Five-Minute Awake Snoring Test for Determining CPAP Pressures (Five-Minute CPAP Test): A Pilot Study

Figure 2

Fixed pressure delivered with a CPAP device (applied via a nasal soft-gel triangle mask) with the patient performing the Five-Minute CPAP Test using supine awake snoring. (a) demonstrates that the patient is able to snore at lower pressures with closure of the upper airway. (b) demonstrates a higher pressure at which the patient can no longer snore (Quiet Pressure) with an open airway. Labels: A = CPAP via a soft-gel nasal triangle mask, B = standard tongue depressor between teeth, and C = upper airway at the level of the soft palate, base of tongue, and epiglottis.
