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. This occurs as the lungs in this case become fibrotic, lose their … Meer weergeven Lung compliance is an important measurement in respiratory physiology. • fibrosis is associated with a decrease in pulmonary compliance. • emphysema/COPD may … Meer weergeven
Web3 nov. 2024 · in mechanically ventilated, normal patients: compliance = 50-100mL/cmH20, resistance = 1-8cmH20/L/s.
