Elastance can be conceptualized as recoil force; highly elastic lungs are stiff and difficult to inflate and exhibit a high recoil force. Compliance is the measure of distensibility of matter and specifies the ease with which matter can be stretched or distorted. Compliance is the inverse of elastance or elastic recoil, compliance=1/elastance. Elastic Recoil of the Lung For many years it was thought that the elastic recoil of the lungs was solely due to the elastin ˜bres present in the lung parenchyma. This notion was disproven by von Neergaard who showed a lung completely ˜lled with saline had much greater compliance.

Compliance is the inverse of elastance or elastic recoil, compliance=1/elastance. 2014-11-08 this! High compliance = less elastic recoil; low compliance = more elastic recoil. A. How lung pressures are expressed We will now discuss compliance of lung structures, or how their volume changes as a function of pressure. The pressure term needs clarification, as it can be expressed in several different ways.

asthma) normal W elastic + W flow-resistive + W negative = W total Emphysema is a disease characterized by dilation of the alveolar spaces and destruction of the alveolar walls. With their loss, much of the elastic recoil of the lung is also lost.

Page 6. Ease of Inflation: Compliance vs. Elastance. Easy to inflate If the mechanical properties of the system change, FRC will change as well: For example, if lung compliance decreases, elastic recoil pressure will increase, and as long as is practicable.
Compliance is like elasticity of hollow tube. Elasticity is less for instance for arteries so they are less compliant. There seems to some sort of relationship between compliance and elasticity. Learning Objectives.

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 . The loss of elastic recoil of the lung affects the pressure difference between the interior of the alveoli and the pleural surface of the lungs, that is, the transpulmonary pressure. As a result, a lung of high compliance, like the emphysematous lung, expands to a greater extent than the one of low compliance, when both are exposed to the same increase in transpulmonary pressure. Conditions that make ventilation difficult (i.e. emphysema) as it diminishes elasticity.

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?

Conditions that make ventilation difficult (i.e. emphysema) as it diminishes elasticity. Explain emphysema in terms of static effective compliance. With destruction of elastic tissue, the lung is easier to inflate but with no recoil, air remains trapped within alveoli as the smaller airways collapse with lung deflation.

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.
