The elastic properties of the respiratory system are the combination of lung properties and chest wall properties. The lung tends to collapse, and exerts a positive pressure at virtually all volumes, whereas the chest wall tends to expand, and exerts a negative pressure. Lung Compliance. Dynamic lung compliance is consistently decreased in infants with BPD70,71 ( Figure 97-4).

In these lessons, we explore topics such as how we get air into our lungs, Se hela listan på philschatz.com Pulmonary Compliance. Pulmonary compliance is reduced by up to 25% in simple obesity and by as much as 40% in patients with the obesity-hypoventilation syndrome.18,19 The primary mechanism of reduced lung compliance is increased blood volume in the pulmonary circulation, although small airway closure related to reductions in functional residual capacity is also a factor. Distributions of vascular volume and compliance in the lung.

Possible causes limiting lung expansion during pleural fluid withdrawal or pneumothorax aspiration include diverse pulmonary diseases resulting in decreased lung compliance (e.g., lung fibrosis), pleural diseases (e.g., those associated with pleural peel formation) and significant endobronchial obstruction resulting in lung atelectasis (Huggins et al., 2007; DiVietro et al., 2011; Gupta et al
2017-02-09 · Like lung volumes, the lung compliance can be measured under static and dynamic conditions. Figure 3 shows the static pressure volume curves (PVC) of the lungs and the chest wall. The entire lung PVC in Fig. 3 falls within the positive limb of P aw , suggesting the tendency of the lungs to collapse at any degree of pulmonary inflation. This study compared pathophysiological and biochemical indexes of acute lung injury in a saline-lavaged rabbit model with different ventilatory strategies: a control group consisting of moderate tidal volume (V(T)) (10-12 ml/kg) and low positive end-expiratory pressure (PEEP) (4-5 cmH(2)O); and thre …

Respirationsfysiologi – Wikipedia
Lung compliance is the volume change that could be achieved in the lungs per unit pressure change. Elastance, also known as the elastic resistance is the reciprocal of compliance, i.e. the pressure change that is required to elicit a unit volume change. In this article we review the profound alterations in lung mechanics (reduced lung compliance and lung volumes), pulmonary gas exchange (reduced diffusing capacity, increased dead space ventilation, chronic arterial hypoxaemia) and airway physiology (increased cough reflex and increased airway volume), as well as pulmonary haemodynamics related LUNG COMPLIANCE It is the measure of the stretchability of lungs defined as the ratio of change in lung volumes to change in trans pulmonary pressure.lung resisting expansion at high volume. C= V P Normal value=200ml/cm of H2o 16.
