The current recommendation for ACPE is for CPAP to be used initially.NPPV should be used only in patients who were hypercapnic and continue to be hypercapnic in spite of the CPAP.This patient is not hypercapnic at this time;therefore,mask CPAP is the appropriate therapy.IPPB is not appropriate because the positive effects of the therapy will be lost after a few minutes off the therapy.
