CPAP interface: satisfaction and side effects.

ABSTRACT

PURPOSE: This study aimed to evaluate the care receiver's satisfaction with the continuous positive airway pressure (CPAP) interfaces. METHODS: A questionnaire with visual analog scales was sent to all our CPAP patients (0 = absolutely unsatisfied, 100 = very satisfied). From the ResMed ResScan program, we obtained the CPAP daily use and air leak values. RESULTS: We received 730 answers (70 % of participants); females comprised 22 %. A total of 391 patients had ResMed interfaces, 227 had Respironics, 87 had Fisher & Paykel (F&P), and 25 patients had other interfaces. Interfaces were nasal for 79 %, nasal pillows for 9 %, oronasal for 9 %, and unidentified for 3 % of cases. The mean ± SD satisfaction rate was 68 ± 25. No statistically significant differences were found regarding the type or brand of interface, previous interface experience, or the age or gender of the patient. Users of ResMed interfaces had significantly (p < 0.01) fewer cases of disturbing leaks than did users of Respironics or F&P interfaces (60 vs. 70 and 72 %, respectively). The ResMed Ultra Mirage interface had the fewest cases of disturbing leaks. Values for the measured median leaks were a mean of 5.9 ± 7.2 l/min, and those for the maximum leaks were 39.3 ± 22.2 l/min with no differences between brands. The users of F&P interfaces experienced significantly (p < 0.01) more comfort and used the CPAP device significantly (p < 0.007) more than did users of ResMed or Respironics interfaces (88 % of cases vs. 65 and 57 % and 6.2 ± 2.6 vs. 5.3 ± 2.8 or 5.8 ± 2.8 h/day, respectively). CONCLUSIONS: The majority of patients consider the use of the CPAP interface disturbing even though the satisfaction rate is good with no differences between brands.
