There is no gas flow, and hence no flow-resistive losses of pressure in the airways, during the respira-tory efforts against an occluded airway. Hence, Pao is equal to PA. This assumption has been challenged [10, 11]. In rediscount form https://makendatec.com

A plethysmograph is an instrument for measuring changes in volume within an organ or whole body (usually resulting from fluctuations in the amount of blood or air it contains). The word is derived from the Greek "plethysmos" (increasing, enlarging, becoming full), and "graphein" (to write).
