Multiple Choice: Chapter 6 Lung mechanics: elastic forces

Question 6.1. When producing a pressure-volume loop for the measurement of static lung compliance

a intrapleural pressure is usually assessed using a cannula passed between the ribs into the intrapleural space
b lung compliance is calculated as volume/intrapleural pressure at functional residual capacity
c the pressure-volume relationship is the same during inspiration and expiration
d measurements of volume and intrapleural pressure are taken as the subject holds his breath because then alveolar pressure is zero.
