For general anesthesia, CPAPs should be used immediately after surgery in the recovery room. CPAPs should be used thoughout the procedure if conscious sedation is used. Please read these manuals found at the ASAA main site which covers this in detail:
CPAP USE IN A HOSPITAL OR SURGICAL SETTING
HOSPITAL CHECKLIST FOR OBSTRUCTIVE SLEEP APNEA PATIENTS
SLEEP APNEA AND SAME-DAY SURGERY
