Static compliance is the compliance measured when there is no gas flow into or out of the lung. Lung compliance and chest wall compliance. Compliance is made up of lung compliance and chest compliance => 1/Ct = 1/Cl + 1/Ccw (Ct = total compliance, Cl = lung compliance, Ccw = chest wall compliance) Factors affecting compliance.

Elastic recoil vs compliance

Therefore, exhalation becomes more difficult as there is less elastic recoil of the lungs. When compliance is low , a high transpulmonary pressure is required to expand the lung to the same V T : the respiratory muscles must then work harder during inspiration and respiratory failure may ensue. to distinguish resistive from elastic recoil-related pressures requires an introduction of an end-inspiratory circuit occlusion after VT delivery. peak pressure will decrease down to a stable plateau pressure (3 second hold) -> this corresponds to the elastic recoil pressure “Quasi-static” Compliance = VT/Pplat – PEEPtotal 3. ELASTIC RECOIL: Airway diameter will be affected by the transmural pressure across them (Fig 2). Although the airways are embedded in the lung, the pressure that they are exposed to on their outside wall is close to intrapleural pressure.

As alveoli are inter-connected, any alveolus tending to collapse will be held open, because it will be supported by the walls of adjoining alveoli; this interaction between alveoli is termed interdependence. Low compliance indicates a stiff lung (one with high elastic recoil) and can be thought of as a thick balloon – this is the case often seen in fibrosis. High compliance indicates a pliable lung (one with low elastic recoil) and can be thought of as a grocery bag – this is the case often seen in emphysema.

I thought this would actually be the opposite of what happens --> with aging the vessels get stiffer, less compliant, and have greater elastic recoil (resistance to being stretched, i.e. elastance). Is this a situation where UWorld is just using the word elasticity to mean compliance?

this!

Compliance is inversely related to the elastic recoil of the lungs, so thickening of lung tissue will decrease lung compliance. The lungs must also be able to overcome the force of surface tension from water on lung tissue during inflation in order to be compliant, and greater surface tension causes lower lung compliance.

High compliance indicates a pliable lung (one with low elastic recoil) and can be thought of as a grocery bag – this is the case often seen in emphysema .

Although the airways are embedded in the lung, the pressure that they are exposed to on their outside wall is close to intrapleural pressure. If elastic recoil is reduced, then intrapleural pressure will be less negative than normal.
