lung compliance

lung compliance

a measure of the ease of expansion of the lungs and thorax, determined by pulmonary volume and elasticity. A high degree of compliance indicates a loss of elastic recoil of the lungs, as in old age or emphysema. Decreased compliance means that a greater change in pressure is needed for a given change in volume, as in atelectasis, edema, fibrosis, pneumonia, or absence of surfactant. Dyspnea on exertion is the main symptom of diminished lung compliance.

It supports real patient monitors and sensors and features dynamic lung compliance that responds to real mechanical ventilation.
Dense pulmonary fibrosis critically affects lung compliance and oxygenation.
There is the release of lung surfactant [11] when lungs have been stretched near to total lung capacity and prostaglandins into alveolar spaces, [12] which increase lung compliance and decreases bronchial smooth muscle tone, respectively.
Decreased lung compliance in obese patients lowered FRC resulting in closure of small airways during ventilation and ventilation perfusion mismatches and hypoxemia.
There are several explanations, most important being changes in lung mechanics with the increase in the overall chest volume and stiffness, lower lung compliance, all of which make respiratory muscles ineffective, weak and prone to fatigue.
Variation in airway resistance (RI) and lung compliance (Cdyn) after reaction with various concentrations of methacholine were measured as described by Pichavant et al.
Results: The dynamic lung compliance decreased significantly at ROSC immediately and 1 h after ROSC compared to baseline (21.
The pulmonary pathology of ALI/ARDS can be divided into acute and fibroproliferative phases [5] which is characterised by diffuse alveolar damage, leakage from alveolar capillaries, and protein rich pulmonary oedema leading to poor lung compliance, severe hypoxaemia, and bilateral infiltrates on chest radiograph.
Assessment techniques that were 'almost never' or 'never' used included calculation of lung compliance (n=75, 69%), calculation of hypoxaemia (n=74, 69%) and assessment of patient readiness for weaning (n=63, 58%).

6] Weight may have effects on pulmonary function tests by causing small airway dysfunction and expiratory flow limitation, alterations in respiratory mechanics, decreased chest wall and lung compliance, decreased respiratory muscle strength and endurance, decreased pulmonary gas exchange, lower control of breathing, and limitations in exercise capacity.
