Pulmonary compliance

From Wikipedia, the free encyclopedia

Compliance of the lungs is an important measurement in respiratory physiology.^[1]^[2]^[3]

fibrosis is associated with a decrease in pulmonary compliance.
emphysema/COPD are associated with an increase in pulmonary compliance.

Pulmonary surfactant increases compliance.

Compliance is greatest at moderate lung volumes, and much lower at volumes which are very low or very high.

Compliance is calculated using the following equation, where ΔV is the change in volume, and ΔP is the change in pressure:^[4]

$C = \frac{ \Delta V}{ \Delta P}$

Respiratory system, physiology: respiratory physiology

Volumes:

lung volumes - vital capacity - functional residual capacity - respiratory minute volume - dead space - spirometry - body plethysmography - peak flow meter

ventilation (V) (positive pressure) breath (inhalation, exhalation) - respiratory rate - respirometer - pulmonary surfactant - compliance - hysteresivity - airway resistance

pulmonary circulation - perfusion (Q) - hypoxic pulmonary vasoconstriction - pulmonary shunt

ventilation/perfusion ratio (V/Q) and scan - zones of the lung - gas exchange - pulmonary gas pressures - alveolar gas equation - hemoglobin - oxygen-haemoglobin dissociation curve (2,3-DPG, Bohr effect, Haldane effect) - carbonic anhydrase (chloride shift) - oxyhemoglobin - respiratory quotient - arterial blood gas - diffusion capacity - Dlco

control of respiration: pons (pneumotaxic center, apneustic center) - medulla (dorsal respiratory group, ventral respiratory group) - chemoreceptors (central, peripheral) - pulmonary stretch receptors - Hering-Breuer reflex

high altitude - oxygen toxicity - hypoxia
