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

Table 2

Quiet Pressures from the Five-Minute CPAP Test, snoring during titration study, and CPAP titration-based prescription (prescriber was blinded). % = percent; AHI = apnea-hypopnea index; BMI = body mass index (in kilograms per meter²); cwp = centimeters of water pressure; LSAT = lowest oxygen saturation; NA = not applicable (two patients started with CPAP and were later converted to bilevel, which they were prescribed); ODI = oxygen desaturation index; and y = years. Note: no patient had cardiac arrhythmias during the titration studies.
