During a CPAP titration study a patient at a CPAP pressure of 15 cm who is still snoring and having hypopneas complains that the pressure feels too high and she cannot sleep. What should the tech do?

During a CPAP titration study a patient at a CPAP pressure of 15 cm who is still snoring and having hypopneas complains that the pressure feels too high and she cannot sleep. What should the tech do?

• A. Lower the CPAP pressure to 13cm and wait for the patient to fall back to sleep before raising it again
• B. Switch to BIPAP of 15/11cm and continue the titration
• C. Raise the CPAP pressure to 17cm
• D. Leave the CPAP at 15cm and wait for the patient to fall back asleep

Answer: (B)

When a patient on CPAP at a high pressure can’t sleep because the pressure feels excessive, the goal is to keep airway support while improving comfort. Switching to BIPAP provides two pressures: an inspiratory pressure that continues to stent the airway during in-breath, and a lower expiratory pressure that makes exhalation easier. This can reduce the sensation of “too high” pressure and improve sleep onset, while still addressing obstructive events. In this scenario, using a BiPAP setup of 15/11 cm H2O maintains the necessary airway support during inspiration (IPAP 15) but lowers the baseline pressure on exhalation (EPAP 11), making it more tolerable. You can then continue titration to see if snoring and hypopneas are resolved at these settings or if adjustments are needed. Lowering to 13 cm could under-treat the events and worsen sleep disruption; raising to 17 cm would worsen comfort; leaving at 15 cm and waiting delays therapy without addressing tolerance.
