During a patient case study,increasing increments of PEEP showed no significant effects until 15 cm H₂O was used,at which time the PₐO₂ improved markedly.This represents the point at which _______________.
A) cardiac output decreased
B) airway resistance decreased
C) hemoglobin saturation improved
D) alveolar recruitment probably occurred

Question

Recruitment maneuvers can produce varying results among patients.In patients who respond to an RM,P_aO₂ increases,P_aCO₂ decreases,and the change in pressure (ΔP)required to cause an acceptable Vᴛ decreases.
