WebCompliance isn't how far apart the lung molecules are from each other as you described. Instead, it's the ability of the tissue to accommodate a change in volume with minimal change in pressure. So when you're expiring, you're already at the more compliant part of the curve. You can't really get more compliant from there. WebContinuous, reliable measurement of static compliance of the lung and thorax is of the utmost importance in state‑of‑the‑art mechanical ventilation. Dynamic compliance cannot be considered a satisfactory substitute, as it is dependent on the airway resistance and can be misleading in various clinical conditions. Cdyn x Pmax (Pmax = set ...
Lung compliance, or pulmonary compliance, is a measure of the lung's ability to stretch and expand (distensibility of elastic tissue). In clinical practice it is separated into two different measurements, static compliance and dynamic compliance. Static lung compliance is the change in volume for any given … Meer weergeven Pulmonary compliance is calculated using the following equation, where ΔV is the change in volume, and ΔP is the change in pleural pressure: For … Meer weergeven Low compliance indicates a stiff lung and means extra work is required to bring in a normal volume of air.
