BIOC34H3 Study Guide - Transpulmonary Pressure, Alveolar Pressure, Pulmonary Compliance
Document Summary
Lecture 10 study notes: lung compliance: a measure of the ease of expansion of the lungs and thorax, compliance = lung volume / (p alv p ip) or lung. t ranspulmonary pressure: refers to the driving force behind lung expansion: not the same as driving force for air flow. change in transpulmonary pressure i. e pressure that drives lung expansion: p alv p ip, contraction of bronchiole smooth muscle (long term changes, mucus secretion www. notesolution. com, normal tidal breath vt is b/n 2200 2700 ml. e. g. asthma or emphysema: restrictive lung disease: fev/fvc is normal or slightly high, as the patient may breath in inadequate amount of air, so the less volume of air in the lungs is expelled. Inert gas technique www. notesolution. com: primarily designed to measure functional residual capacity ( frc = Erv + rv: 10% helium is primarily used.
