†Preferably 24 hours before the objective testing or PAP titration; however, not earlier than 48 hours prior to the procedures. *Seventy-two hours quarantine device before the objective testing. ‡After sanitization according to local adopted health care facilities. §Seventy-two hours quarantine PAP device before the titration. HST = home sleep testing, OSA = obstructive sleep apnea, PAP = positive airway pressure, PSG = polysomnography, SARS-CoV-2 = severe acute respiratory syndrome coronavirus 2.
