Document Summary

Lung compliance: the ability of lungs to stretch a lot when being healthy, measure of change in lung volume that occurs with change in transpulmonary pressure, equation, higher compliance= easier to expand the lungs, depends on 1. Alveolar ventilation in one minute: minute ventilation is the total amount of gas flow in/out of the respiratory tract, normal at rest is 6l/min, exercise is around 200l/min, alveolar ventilation rate (avr) is the flow of air in/out of alveoli during a. Gas exchanges between the blood, lungs, and tissues. Respiratory pressure in relation to patm: negative respiratory pressure is lower than atmospheric pressure, positive respiratory pressure is higher than atmospheric pressure, zero respiratory pressure equals one atmospheric pressure, air always moves from high to low pressure. Gas exchange between the blood, lungs and tissues. Thickness and surface area of the membrane: only 0. 5 to 1 micrometer thick and gas exchange is very efficient, large total surface area.
