What does the term lung compliance refer to quizlet?

What is lung compliance? A measure of how easily the lung can be stretched out or inflated. Therefore, compliance is similar to distensibility.

What determines lung compliance?

Two factors determine lung compliance: elasticity of the lung tissue and surface tensions at air water interfaces. Two factors determine lung compliance – elasticity of the lung tissue and surface tensions at air water interfaces.

Which condition does the term compliance refer to?

Compliance is defined as. change in volume / change in pressure (L/ cm water) also compliance = 1 / elasticity (or stiffness)

What is compliance in COPD?

Compliance refers to the distensibility of an elastic structure (such as the lung) and is defined as the change in volume of that structure produced by a change in pressure across the structure. Thus, the lungs in emphysema would be considered highly compliant. See Also: Emphysema.

What is lung compliance affected by quizlet?

Compliance is inversely related to elastance. More elastic tissue means greater recoil force therefore lower compliance. A thinner rubber band is easier to stretch than a thicker one. What is the relationship between lung volume and intra-pleural pressure?

What does decreased lung compliance mean?

A low lung compliance means that the lungs are “stiff” and have a higher than normal level of elastic recoil. A stiff lung would need a greater-than-average change in pleural pressure to change the volume of the lungs, and breathing becomes more difficult as a result.

What is lung compliance and why is it important?

Pulmonary compliance, a measure of the lung expandability, is important in ideal respiratory system function. It refers to the ability of the lungs to stretch and expand. Lung compliance can be calculated by dividing volume by pressure.

Two factors determine lung compliance: elasticity of the lung tissue and surface tensions at air water interfaces. Two factors determine lung compliance – elasticity of the lung tissue and surface tensions at air water interfaces.

What is normal lung compliance?

The compliance of healthy lungs is approximately 0.2L per cmH 2O. The compliance of the chest wall is also closer to 0.2 L per cmH 2O. Thus, the compliance of the respiratory system becomes less (0.1L per cmH 2O).

What is normal range for lung compliance?

Normal lungs usually develop a decrease in lung volume and compliance after receiving positive-pressure ventilation for a few hours. Thus normal static compliance values in patients receiving mechanical ventilation range from 40 to 60 ml/cm H 2O.

What is compliance of the lungs?

Lung compliance. Lung compliance, or pulmonary compliance, is a measure of the lung’s ability to stretch and expand (distensibility of elastic tissue).
