ABSTRACT
Follow-up of patients should focus on efficacy, side effects, and compliance. The outcome measures of treatment efficacy include improved vigilance, daytime performance, quality of life measures, and effect on cardiovascular morbidity including HTN, as noted earlier (37). Kribbs et al. (38), found that only 46% of patients used at least 4 hr of CPAP on 70% of the nights. Patients generally overestimate the hours of CPAP use. Most CPAP machines have built-in meters to record the duration of time that the machine has been running or has been in actual use and can be used to objectively measure compliance.
