109(7):785-802. Die Chronisch obstruktive Lungenerkrankung (englisch chronic obstructive pulmonary disease, Abkürzung: COPD, seltener auch chronic obstructive lung disease, COLD, chronic obstructive airway disease, COAD; übersetzt „dauerhaft atemwegsverengende Lungenerkrankung“, im ICD-Klassifikationssystem Chronische obstruktive Atemwegserkrankung genannt) ist ein Krankheitsbild … Überblähung: FRC↑, RV↑, RV/TLC↑ At FRC, the inward elastic forces of the lung are in equilibrium with the outward elastic forces of the chest wall. Bei COPD ist die FRC erhöht. Die funktionelle Restkapazität (FRC) bezieht sich auf das Luftvolumen, das nach einer normalen, passiven Ausatmung in der Lunge verbleibt. Most patients will have been smoking cigarettes for many years (probably in excess of 20 pack years). Selvi E C, K V Rao K, Malathi. Increased lung volumes, particularly residual volume (RV), are commonly observed in airway obstruction. Airflow obstruction in COPD patients is believed to be largely secondary to airway damage and remodeling, while emphysema is considered to play only a minor role. Die anderen umfassen ein erzwungenes exspiratorisches Reservevolumen (FEV), das misst, wie viel Luft Sie in einer Sekunde kräftig ausatmen können, und eine erzwungene Vitalkapazität (FVC), die das Gesamtvolumen der Luft misst, die aus den Lungen geworfen wird. During general anaesthesia FRC is reduced by approximately 20%. Wenn dies geschieht, müssen Sie schneller atmen, um genügend Luft in Ihre Lungen zu bekommen. It is composed of ERV and RV, and is usually … Diagnosis of COPD History. Gas trapping is an additional mechanism. Hyperinflation and air-trapping are terms commonly used to reflect these changes, but are not well standardized. This multicentre, randomised, double-blind, single-dose, cross-over, placebo-controlled study evaluated efficacy and safety of the … Dual bronchodilator therapy is recommended for symptomatic patients with chronic obstructive pulmonary disease (COPD). StatPearls Publishing; 2019-. •The earliest alteration of static lung volume in COPD patient is the hyperinflation of TLC. Trotzdem geben die meisten Patienten eine Abnahme der Dys- pnoe an. COPD und funktionelle Restkapazität (FRC) - Copd - 2021, Warum funktionelle Restkapazität wichtig ist, Die Verbindung zwischen COPD und funktionaler Restkapazität, Kann HIIT nicht tun? doi:10.7860/JCDR/2012/4876.2666, Borg BM, Thompson BR. Although measurements of airflows are essential for the diagnosis of COPD and commonly used in disease staging, the effects of the disease on lung volumes correlate better with patient symptoms and impairment of functional capabilities 7 Internationale Zeitschrift für chronisch obstruktive Lungenerkrankung . Dies verändert das Gleichgewicht in der Art und Weise, wie wir atmen, und führt zu einer erhöhten FRC (Hyperinflation). 2. bei Asthma bronchiale) Air trapping: … ; und O'Donnell, D.

Ausatemlage Atemruhelage Residualvolumen RV Residualvolumen Zeit Volumen 1s TLC RV Forc. Respiratory Journal der Primärversorgung . Die zurückgehaltene Luft (bekannt als funktionelles Restvolumen) ermöglicht es der Lunge, sich mit weniger Kraft zu füllen, während die elastischen Kräfte beim Einatmen und Ausatmen im Gleichgewicht bleiben. Traditionally, an increase in “static” FRC refers to an increase in V r due to loss of lung recoil which resets the balance of forces between the lung and chest wall [ 10, 11 ]. Standardisation of the measurement of lung volumes, Relation among body mass index, waist-hip ratio, and pulmonary functional residual capacity in normal weight versus obese Chilean children: A cross-sectional study, Effects of increased functional residual capacity on finger-floor distance in healthy young adults. •The earliest alteration of static lung volume in COPD patient is the hyperinflation of TLC. The term EELV is used inter- changeably with FRC in the current review. With this definition in mind, pathologies which change these elastic forces will also change the FRC. Takeuchi Y, Kato H, Ishizaka M, Kubo A. 2015. Als Lungenfunktion (früher auch als Atmungsfunktionen bezeichnet) wird die physiologische Befähigung der Lunge als Organ für den Gasaustausch bei der äußeren Atmung von lungenatmenden Schnecken, Amphibien, Reptilien, Vögeln und Säugetieren einschließlich des Menschen bezeichnet. Sie kann abnehmen, wenn auf das Zwerchfell ein anhaltender Druck ausgeübt wird. Wenn sie jedoch nicht im Gleichgewicht sind, ist unsere Fähigkeit, Sauerstoffmoleküle in unserem Blut zu absorbieren oder Kohlendioxid aus unserem Blut zu entfernen, beeinträchtigt. COPD ist gekennzeichnet durch einen Verlust des elastischen Rückschlags der Lunge. Volumen FEV 1 pneumo_pocket_2007.book Page 71 Wednesday, June 6, 2007 11:04 AM. "Mechanismen, Bewertung und therapeutische Implikationen der Hyperinflation der Lunge bei COPD." Das gleiche Prinzip gilt für die Lunge. As you inhale and exhale, the concentration of helium remaining in the spirometer can be used to calculate your FRC. Es wird zur Beurteilung der Elastizität der Lunge und der Brustwand bei Personen mit Atemwegserkrankungen wie chronisch obstruktiver Lungenerkrankung (COPD) verwendet. Lung Volumes. Einatemlage Max. Lung volumes in COPD 1. In: StatPearls [Internet]. Diagnosis of COPD History. Surfactant, a sticky substance that lines the outside of your alveoli, helps pull them open. There are limited data on effects of a combination of two long-acting bronchodilators on lung function including body plethysmography. Hier lohnt ein kurzer Blick in die Pathophysiologie der Atemarbeit. You regularly breathe in and out at a rate of 10 to 20 breaths per minute. V d F was 30 ml lower in the Asthma than in the COPD group. William MacNee, in Clinical Respiratory Medicine (Fourth Edition), 2012. Ten measurements were taken from the RV and 10 from the FRC, taken alternately with an interval of 1 minute between each measurement, for five consecutive days.

Sie schränkt Ihre Bewegungsfähigkeit oder anstrengende Arbeit ein, da einfach nicht genug Sauerstoff eingeatmet wird, um Ihre Muskel-, Herz- und Gehirnzellen zu versorgen. Thus, IC is an easy and … FRC in Lung Diseases. Functional closure of small airways can occur during tidal breathing above functional residual capacity (FRC) both in asthma and COPD patients, especially during exacerbations. Normally, FRC values range between approximately 1800 ml to 2500 ml. [3] Eine Studie, die im Januar 2007 in Salzburg veröffentlicht wurd… Dual bronchodilator therapy is recommended for symptomatic patients with chronic obstructive pulmonary disease (COPD). Die FRC misst den Punkt, an dem die nach innen gerichteten Kräfte der Lunge mit der Tendenz der Brustwand nach außen konkurrieren. There are limited data on effects of a combination of two long-acting bronchodilators on lung function including body plethysmography. The purpose of the present study was to evaluate the acute effect of four inhaled bronchodilators (salbutamol, formoterol, salmeterol and oxitropium) and placebo on IC, FEV1, FVC, FEV1/FVC and dyspnoea at rest in COPD patients, and to assess the correlation between the changes in these variables. Results can also help in the diagnosis of lung disease—specifically when differentiating between restrictive and obstructive lung disease., FRC = ERV (the amount of extra air you can exhale if you do so forcefully) + RV (the amount of air remaining in the lungs no matter the extent of exhalation). 22(1):101-11. 2013. Evidence exists to support the effectiveness of pursed lips … 200 mL) Effekte einer inhalativen Glucocorticoidtherapie: Kein wesentlicher Anstieg der FEV 1 /VC nach Anwendung über 4–6 Wochen bei COPD ; Spezielle Konstellationen bei COPD und Emphysem. Respiratory Care. Tests that measure FRC include a lung plethysmograph or a helium dilution method.. During general anaesthesia FRC is reduced by approximately 20%. 2 Hintergrund Die funktionelle Residualkapazität ist die Summe aus Residualvolumen und exspiratorischem Reservevolumen und entspricht damit dem endexspiratorischen Lungenvolumen (EELV). This approach is also justified by the present unavailability … It is the volume of gas present in the lung at end-expiration during tidal breathing. Hyperinflation is the ratio of FRC to total lung capacity (TLC), whilst gas trapping is the residual volume (RV) to TLC ratio. The Measurement of Lung Volumes Using Body Plethysmography: A Comparison of Methodologies. All of these values can all be altered by lung diseases: If you have pulmonary disease, your doctor may prescribe respiratory therapy and physical therapy to help improve your breathing abilities. TLC may be normal, but is frequently increased in the late stages of COPD. The calculation of your FRC is based on a mathematical formula that incorporates the amount of air that you breathe in and out, as well as the volume of air in your lungs.. 50–60J. As obesity can lead to a reduction of functional residual capacity (FRC) in lung-healthy subjects, more recent approaches included body weight or body surface area. The two main symptoms of COPD are breathlessness and cough which may or may not be productive of purulent sputum. FRC ist nur ein Test, den ein Arzt verwendet, um Ihre COPD zu bewerten. Diese Defizite verschlimmern nur die Symptome der COPD und sind der Hauptgrund, warum körperliche Konditionierung für Menschen, die mit der Krankheit leben, so wichtig ist. 2012;57(7):1076-1083. doi:10.4187/respcare.01444, O'Donnell CR, Bankier AA, Stiebellehner L, Reilly JJ, Brown R, Loring SH. At FRC, the opposing elastic recoil forces of the lungs and chest wall are in equilibrium and there is no exertion by the diaphragm or other respiratory muscles. Plethysmography Tests the Volume of Your Lungs. 9:187-201. High-flow nasal cannula oxygen therapy carried less risk of treatment failure than non-invasive ventilation among patients with COPD who had hypercapnic respiratory failure. The variability of lung volumes related to Future studies FRC 1,2 l 1,5 l 1,0 l 4,8 l 3,8 l 3,6 l 20–30J. Diagnose der COPD. The key parameter I want to emphasize is the functional residual capacity (FRC) – the air remaining in our lungs after a passive expiration. COPD patients Claudio M Sanguinetti1,2 Abstract Chronic obstructive pulmonary disease (COPD) is characterized by persistent airflow limitation caused by bronchial alterations, small airways disease and parenchymal destruction. FRC is the functional residual capacity. FRC mbw was normal in both groups, whereas FRC pl values were on average 690 and 1,058 ml larger than respective FRC mbw values in the Asthma and COPD groups, such that FRC pl was not significantly different between both groups. This procedure, also called pulmonary plethysmography or whole-body plethysmography, requires that you enter into a small chamber and breath into a mouthpiece. ; Avdeev, S; et al. Nicht-medikamentöse Maßnahmen erhalten künftig einen stärkeren Stellenwert. 3. As you breathe in and out, the air pressure inside the chamber is measured. 2013;7(1):43–45. exspir. When you have your FRC measured, you are likely to have other pulmonary function tests (PFTs) as well. 72 6 Lungenfunktionsprüfung Ventilation AF Atemfrequenz: [12-20/min] FVC Forcierte exspiratorische … An Overview of Functional Residual Capacity (FRC), Ⓒ 2021 About, Inc. (Dotdash) — All rights reserved. For example, lung elasticity is significantly reduced in emphysema (a form of chronic obstructive pulmonary disease) thereby increasing FRC and leading to hyperinflation. The present study was undertaken to investigate the safety and efficacy of a mixture of nitric oxide (NO) and oxygen … Deborah Leader RN, PHN, is a registered nurse and medical writer who focuses on COPD. Should the Functional Residual Capacity be Ignored? Normally, FRC at rest is determined by the static characteristics of the lung and chest wall. In patients with COPD, breathing techniques aim to relieve symptoms and ameliorate adverse physiological effects by: 1) increasing strength and endurance of the respiratory muscles; 2) optimizing the pattern of thoracoabdominal motion; and 3) reducing dynamic hyperinflation of the rib cage and improving gas exchange. bei Asthma bronchiale) Air trapping: … After a lung transplant, you need to take medication to keep from rejecting the transplant. 2019 Aug 1;117(4):230-236. doi:10.5546/aap.2019.eng.230. Gas trapping is an additional mechanism. The Measurement of Lung Volumes Using Body Plethysmography: A Comparison of Methodologies. If thes Die funktionelle Residualkapazität ist das Gasvolumen, welches nach einer normalen Exspiration in Ruhe noch in den Lungen verbleibt. In diesem Fall würde ein FRC zur Überwachung des Fortschritts verwendet. FRC is of clinical significance for two reasons. FRC or the lung volume at the end of quiet expiration during tidal breathing (i.e., EELV) is increased in COPD compared with health. Wichtig für die Diagnose obstruktiver Lungenerkrankungen, wie der COPD, ist vor allem der FEV1-Wert (der auch mit der Spirometrie gemessen werden kann). The term EELV is used inter- changeably with FRC in the current review. ; et al. Im medizinischen Alltag hat sich der Begriff Lungenfunktion (Abk. How Can Inspiratory Capacity Help Manage My Lung Disease? Auch die Häufigkeit und Intensität der Beschwerden sowie das Ausmaß der Beeinträchtigung im Alltag werden abgeklärt. Q&A : True or False ? In schweren Fällen, in denen Bewegung nicht möglich ist, kann zur Verbesserung der Atmung ein positiver endexspiratorischer Druck (PEEP) (eine nichtinvasive Beatmungsform) verwendet werden. This is best understood by introducing the concept of the time constant. 3. Umgang mit Kopfschmerzen nach einem Schlaganfall. ease (COPD) is often associated with lung hyperinflation. (FRC) may also play a role in nocturnal hypoxaemia in COPD. 2. Der FRC kann sich auch aufgrund anderer Bedingungen außerhalb der COPD ändern. Muñoz Cofré R, Del Sol M, Medina González P, Escobar Inostroza J, Lizana PA, Conei D, Escobar Cabello M. Relation among body mass index, waist-hip ratio, and pulmonary functional residual capacity in normal weight versus obese Chilean children: A cross-sectional study. It should be noted that FRC is not always synonymous with the static equilibrium volume of the relaxed respiratory system; V Thank you, {{form.email}}, for signing up. Bei COPD ist die FRC erhöht. 4 Lung volume and divisions Ex VC Physiology EtELV RV TLC ERV IRV Time e IC = Vt+IRV 0 V T. . Chest. FRC ist nur ein Test, den ein Arzt zur Beurteilung Ihrer COPD durchführen wird. This is due to a number of factors. An increase in FRC measured at rest has both static and dynamic determinants in COPD [ 17 ]. 2005;26(3):511-522. doi:10.1183/09031936.05.00035005. Patients diagnosed with COPD, asthma, chronic bronchitis, and emphysema tend to have a higher FRC. FRC ist nur ein Test, den ein Arzt zur Beurteilung Ihrer COPD durchführen wird. Stellen Sie sich einen Ballon vor, den er leichter füllen kann, wenn er bereits halb aufgeblasen ist. J Clin Diagn Res. PMID: 6731476 Atemzug-volumen V T max. In hyperinflated COPD or asthma patients, the end-expiratory lung volume (EELV Hyperinfl) is greater than the respiratory system relaxation volume, increasing ΔFRC (Δ denoting the increase in volume from the normal FRC); at this increased volume, an inward recoil pressure exists (the pressure of the respiratory system is 7 cmH 2 O relative to the atmosphere). These measurements are not necessary in every patient. BACKGROUND Inhalation of nitric oxide with oxygen could be a promising treatment in patients with chronic obstructive pulmonary disease (COPD) and pulmonary hypertension. Von den zehn häufigsten zum Tod führenden Krankheiten ist sie die einzige, deren Häufigkeit zunimmt. Atemwegsmedizin . 1 As a consequence, the pharmacologic interventions recommended for COPD patients 1 are uniquely aimed at increasing airway caliber and reducing airway inflammation. Die bedeutendste un… Q&A : True or False ? Die anderen beinhalten ein forciertes exspiratorisches Reservevolumen (FEV), das misst, wie viel Luft Sie in einer Sekunde kraftvoll ausatmen können, und forcierte Vitalkapazität (FVC), die das Gesamtvolumen der aus den Lungen ausgestoßenen Luft misst. Sanja Jelic, MD, is board-certified in sleep medicine, critical care medicine, pulmonary disease, and internal medicine. This is, in our opinion, a major concern because TLC in COPD patients varies as a function of the prevalent phenotype (increased in emphysema, often normal in chronic bronchitis); therefore, it cannot be used routinely to address pulmonary hyperinflation in COPD. Accentuated physiological hypoventilation due to central respiratory effects Ventilatory control in patients with COPD follows the same basic principles as in normal subjects. This test uses a spirometer, which is a simple device that you can breathe into and out of. Hyperinflation führt wiederum zu einem Zustand, den wir Dyspnoe oder Kurzatmigkeit nennen. Symptoms Pulmonary functions A S T H M A 2. Schätzungen gehen davon aus, dass in Deutschland drei bis fünf Millionen, in den USA etwa 16 Millionen und weltweit etwa 600 Millionen Menschen an einer COPD erkrankt sind. Tests used to measure your FRC are safe, even if you have advanced lung disease.. Arch Argent Pediatr. ; Guenette, J . Calculation of your FRC is a bit complicated, because this number reflects the air remaining inside your lungs, which cannot be directly measured. . Functional residual capacity (FRC) refers to the volume of air left in the lungs after a normal, passive exhalation. In this review, we exam- ine the mechanisms that may cause functional residual capacity (FRC), residual volume (RV) and total lung capacity (TLC) to increase during acute and chronic airway obstruction. Wie kann ich sagen, ob es sich um einen Schlaganfall oder eine Parkinson-Krankheit handelt? •A reduction of Slow VC reflects the hyperinflation in COPD. Such event has several noxious consequences on gas exchange, airway hyperresponsiveness and mechanical stress and strain within lung tissue and airway wall, mostly due to increase in ventilation heterogeneity. 6 In conclusion, the article by O’Donnell and colleagues 1 has merit in documenting substantial differences in lung volumes assessed by different methods in patients with severe COPD. This multicentre, randomised, double-blind, single-dose, cross-over, placebo-controlled study evaluated efficacy and safety of the … COPD patients Claudio M Sanguinetti1,2 Abstract Chronic obstructive pulmonary disease (COPD) is characterized by persistent airflow limitation caused by bronchial alterations, small airways disease and parenchymal destruction. Intrathorakale Atemwegsstenosen: Asthma bronchiale, COPD, Tumoren; Extrathorakale Atemwegsstenosen: Larynxtumor, Stimmbandparese; Befunde in der Spirometrie. •Forced VC is smaller than Slow VC in COPD. After salbutamol administration, all lung function and MBW indices measured in the Asthma group … It should be noted that FRC is not always synonymous with the static equilibrium volume of the relaxed respiratory system; Vr is the volume at which the elastic recoil … COPD bewirkt eine allgemeine körperliche De-Konditionierung, die sowohl die Muskelkraft als auch die Elastizität der Brustwand beeinflusst. The most likely mechanism is the loss of inspiratory muscle tone of the muscles acting on the rib cage. Finally, an indication about the response to combined inhaled long acting beta-2-agonist and inhaled corticosteroid therapy among different COPD subtypes … By using Verywell Health, you accept our, Pulmonary Function Tests Can Evaluate Your Lung Function. An increase in FRC remains a useful index of pulmonary emphysema, even in the presence of chronic airway disease. But this number depends on several factors, such as age, weight, height, gender, and pregnancy. Pulmonary function testing (PFT) is a complete evaluation of the respiratory system including patient history, physical examinations, and tests of pulmonary function. Obstructive and Restrictive Lung Disease Differences and Treatment, Getting a Forced Vital Capacity (FVC) Test, Your FEV1 Is a Valuable Measure of Lung Function, How Doctors Choose Which Tests to Diagnose Emphysema, chronic obstructive pulmonary disease (COPD). This raises the question whether these models are appropriate in patients with COPD-induced hyperinflation. FRC ist nur ein Test, den ein Arzt verwendet, um Ihre COPD zu bewerten. It should be noted that FRC is not always synonymous with the static equilibrium volume of the relaxed respiratory system; V J Phys Ther Sci. FRC or the lung volume at the end of quiet expiration during tidal breathing (i.e., EELV) is increased in COPD compared with health. The tests used to measure FRC rely on indirect calculations to determine the volume of air in your lungs after you breathe out. 6 In conclusion, the article by O’Donnell and colleagues 1 has merit in documenting substantial differences in lung volumes assessed by different methods in patients with severe COPD. The volume of remaining air after a normal breath is called the FRC. The most likely mechanism is the loss of inspiratory muscle tone of the muscles acting on the rib cage. In den USA stellt die COPD die vierthäufigste Todesursache dar:[2] Man kann von einer Volkskrankheit sprechen. Verywell Health uses only high-quality sources, including peer-reviewed studies, to support the facts within our articles. FRC in Lung Diseases. The primary purpose of pulmonary function testing is to identify the severity of pulmonary impairment. Treasure Island (FL): StatPearls Publishing; 2019 Jan-. Aufgrund Ihres körperlichen Zustands und der Schwere Ihrer Symptome kann Ihr Arzt in Verbindung mit einem auf Ihre Einschränkungen zugeschnittenen Fitnessprogramm eine Physiotherapie verordnen. Wenn Sie ausatmen, stoßen Sie nicht die gesamte Luft aus Ihren Lungen aus. •FRC increases with the supine posture, age and obesity. It is used to evaluate the elasticity of the lungs and chest wall in persons with respiratory illnesses like chronic obstructive pulmonary disease (COPD). Epub 2019 Jan 10. You can benefit from doing these exercises with a therapist, or you may learn how to do them on your own at home. Wenn Einatmen und Ausatmen im Gleichgewicht sind, gibt es keine Konkurrenz und die Atmung wird als normal angesehen. Functional residual capacity (FRC) is the volume of air left in your lungs after a normal, passive exhalation. Delgado BJ, Bajaj T. Physiology, Lung Capacity. Should the Functional Residual Capacity be Ignored?. Das gelingt mit einer dualen Bronchodilatation. •A reduction of Slow VC reflects the hyperinflation in COPD. In these conditions, lung hyperinflation develops characterized by increase in functional residual capacity (FRC) and decrease in inspiratory capacity (IC). ; Decramer, M . FRC or the lung volume at the end of quiet expiration during tidal breathing (i.e., EELV) is increased in COPD compared with health. COPD exacerbations have a great impact on health, both short and long term, ... TLC, FRC and D L CO), along with computed tomography assessment of lung density, one can propose clinical COPD phenotypes using multivariate models . FRC is a reflection of how elastic your lungs are, and your medical team may use your FRC measurements to evaluate how well the treatment you are using for your lung disease is working or whether your condition is progressing. FRC ist in gewisser Weise ein besseres Maß für das, was wirklich in Ihrer Lunge passiert, da die meisten Atemzüge eher passiv als kraftvoll ausatmen. The elasticity of the lungs also keeps your alveoli partially inflated. Conversely, RV and FRC are strongly related to the severity of airflow obstruction. Comparison of plethysmographic and helium dilution lung volumes: which is best for COPD?. COPD is the most common reason for a lung transplant. COPD ja durch eine irreversible Obstruktion charakterisiert ist. Static lung volumes such as TLC, residual volume (RV) and FRC, and the ratio RV/TLC are measured in patients with COPD, to assess the degree of overinflation and gas trapping, and are usually increased. The primary purpose of pulmonary function testing is to identify the severity of pulmonary impairment. Thomas, M . Patients were examined using a manual vacuometer to measur the MIP of 20 daily manoeuvres. Future studies ; Aisanov, Z . COPD, it can be observed that RV increase usually antedates that of FRC and then TLC. [Updated 2019 Mar 14]. The literature dealing with the magnitude, mechanism and effects of reduced FRC in the perioperative period is reviewed.

Wichtig ist dabei zu klären, ob Risikofaktoren vorliegen, also etwa ob der Patient/die Patientin raucht beziehungsweise geraucht hat, oder im Beruf potenziell schädigenden Substanzen ausgesetzt ist. Methods: A retrospective analysis of patients attending for static and dynamic volumes was undertaken. . Most patients will have been smoking cigarettes for many years (probably in excess of 20 pack years). Due to the impaired lung capacity, a fair amount of air remains inside the lungs after exhalation, resulting in greater FRC. COPD charges a relevant social and economic burden, ... Noteworthy is the observation that FRC increases exponentially with the progressive reduction of FEV 1 and the most significant change after bronchodilation is the decrease in FRC and RV, that is in LH, independently from the basal FEV 1 value . Dies kann während der Schwangerschaft der Fall sein, wenn Ihre Leber oder Milz vergrößert wird oder wenn sich im Unterleib angesammelte Flüssigkeit (Aszites) befindet, die durch Zirrhose oder Leberkrebs verursacht wird. Damit muss von einem globalen Phänomen gesprochen werden. 60–70J.
