I had second sleep study with cpap titration. i didn't sleep all night, was this a waste of time?

Not necessarily: As a patient, CPAP titrations can be frustrating. The ideal situation is to sleep on multiple pressures to determine which works best for your sleep apnea. Your dr. May still make recommendations @ a certain pressure, if sleep segments were still seen ; improvement was seen @ those pressures. Moreover, an auto. Positive airway pressure (apap) device may be an alternative treatment plan by your dr.
