Background: Appropriate CPAP interface selection, sizing and education have been documented to improve CPAP compliance. This study assesses the effect on compliance when a patient is allowed to acclimate to wearing an interface at a low CPAP pressure while waiting for their titration polysomnogram to be performed. CPAP pressure is then adjusted to the optimal level post titration study.

Methods: 50 OSA patients were divided equally into two groups. All received C-Series Tango CPAP (ResMed) with heated humidification, interface of choice and the same educational materials/instruction. Group One were setup on CPAP at a pressure of +6 cmH20 while waiting for titration study to be performed and optimal pressure set once determined by titration. Group Two received CPAP only after optimal pressure was determined. Compliance comparison using hour meter reading was performed at 30, 60 and 90 days after the optimal pressure was applied for Group One versus Group Two.

Results: Group One patients averaged 17.3 days on CPAP prior to their titration polysomnogram. There was improved compliance for Group One of 46 minutes (12%) at 30 days, 34 minutes (5%) at 60 days and 37 minutes (10%) at 90 days.

Conclusion: CPAP compliance is improved when the patient is desensitized to the interface at a minimal pressure prior to setting the patient on their optimal pressure. Further study is needed to further evaluate the effect this desensitization has on long term compliance.
