Chest wall compliance is the opposite of elasticity, and elasticity is the tendency of lung tissue to return to its original (or relaxed) position after an applied force has been removed. Compliance is essentially the ability of the lung tissue to “absorb” the same applied force, which generally results from a change in intrathoracic pressure.

Låg compliance ses vid restriktiva lungsjukdomar p.g.a. att lungans återfjädringstryck ökar; det vill säga IRDS (infant respiratory distress syndrome).

• Compliance is a measure of lung distensibility. In restrictive lung disease (fibrosis) the lung has low compliance (i.e., hard to inflate). Because compliance has a direct relationship with the lung volume available for ventilation, loss of lung volume (e.g. during atelectasis, pneumonia or pulmonary oedema) will cause a proportional drop in compliance. The concept of ‘baby lung’, introduced in (p. 339) the middle of 1980s showed that, in most ARDS patients, the normally Den lätthet varmed lungan kan sträckas ut kallas för lungans följsamhet ( compliance) och avgörs av två faktorer: sträckningsmöjligheten hos de elastiska fibrer som lungan består av. Utgör 1/3 av lungans elastiska kapacitet.

See also: compliance Note the lung volume at (1) does not start at zero. There is a reserve volume in the lungs- they are never completely empty. The ventilator then starts to increase the pressure in the lung as it initiates the breath. However the lung volume does not change initially as the lung compliance is low at this stage (2). Remember the balloon analogy here.

The measurements of lung compliance, airway resistance and respiratory dead space as clinical tests have gradually fallen into disuse as the standard pulmonary function testing procedures; spirometry, lung volume and diffusing capacity measurement, followed, if necessary, by imaging have become the norm for diagnosis of COPD and other lung diseases.

It is independent of airway resistance. Normal compliance in a nonmechanically ventilated patient is 60 to 100 ml/cm H 2 O. Low compliance of 25 to 30 ml/cm H 2 O is common with pulmonary edema, interstitial lung disease, lung hyperinflation, pleural disease, obesity, bronchial intubation and ascites.2 Dynamic compliance (C D) measures both lung compliance and airway resistance (R aw Objectives 1.
