Effects of recruitment of collapsed lung units on the elastic pressure–volume relationship in anaesthetised healthy adults

Background: The elastic pressure–volume (Pel–V) curve of the respiratory system can be used as a guide for improved ventilator management. The understanding of curves recorded for sick patients can be improved with better knowledge of the Pel–V relationship observed in healthy humans. Dynamic Pel–V curves were determined over an extended volume range in 15 anaesthetised and muscle‐relaxed healthy humans. The influence of a recruitment manoeuvre was studied.
