TPAP for Comfort in OSA

The TheraPAP Comfort Study is an in-office study to assess comfort of TPAP vs. CPAP in CPAP-naïve patients with OSA during supine wakefulness. Patients will be recruited after routine outpatient visits. They will be asked to breath normally for approximately 1 minute in supine wakefulness while being administered background CPAP (at 9 or 13 cmH2O) or TPAP at various pressure drops. TPAP drops will be administered in a paired comparison before or/and after each corresponding CPAP level, according to a randomized design. Eventually, 6 one-to-one comparisons (TPAP vs. corresponding background CPAP or TPAP vs. TPAP) will be made, 3 per each randomized order. As an example, CPAP 9 will be compared to TPAP 1/1 cmH2O drops; CPAP 9 will be compared to TPAP 2/2 cmH2O drops; and TPAP 1/1 cmH2O drops will be compared to TPAP 2/2 cmH2O drops in a random sequence.
