reflection objectives: To evaluate the result of interface on objective compliance.

reflection objectives: To evaluate the result of interface on objective compliance, patient satisfaction, adverse powers quality of life, and residual sleep-disordered breathing in patients with obstructive slumber apnea/hypopnea syndrome (OSAHS) using continuous positive airway squeezing (CPAP).

Design: Randomized, cross-over

Setting: couple suburban community-based hospital sleep laboratories.

Patients: Data were consider probableed on 39 patients with OSAHS (mean age, 487 years), in whom CPAP was a novel treatment.

Interventions: Interventions were nasal pillows (Breeze; Mallinckrodt Corporation; Minneapolis, MN) and nasal mask (Contour; Respironics; Murrysville, PA).

Measurements and results: results assessed at the completion of each 3-week treatment period were objective compliance, adverse general intents and satisfaction with CPAP (CPAP questionnaire), daytime sleepiness (Epworth sleepiness scale [ESS]) quality of life (Functional issues of Sleep Questionnaire [FOSQ]), be still diary, and residual sleep-disordered breathing (apnea-hypopnea index [AHI]). Patients were randomly assigned to use the nasal pillows or the nasal mask following laboratory titration and initiated upon CPAP (pressure range, 5 to 14 cm [Hsub2]O) The percentage of days utilized favored the nasal pillows (941% v 857%; p = 002) nevertheless minutes of use per night did not differ (nasal pillows, 223 min; nasal mask, 288 min). ES scores were lower and the FOSQ total scores were higher following CPAP treatment (p < 0001) further no differential treatment effects were noted. Fewer adverse powers less trouble getting to be dead and staying asleep, and les air leak were reported with nasal pillows (p < 004) The mean [+ or -] SD pretreatment AHI (471 [+ or -] 351/h) was significantly lower following treatment with CPAP for the two types of interface (nasal pillows, 102 [+ or -] 98/h; nasal mask, 70 [+ or -] 77/h; p < 0001)

Conclusions: Nasal pillows are a well-tolerated and effective interface for OSAHS patients receiving CPAP at [les than or equal to] 14 cm [Hsub2]O Use of nasal pillows was associated with fewer adverse powers and better sleep quality during the first 3 weeks of CPAP therapy. Further investigation is needinessed to determine whether interface original affects long-term CPAP use.

**********

Continuous positive airway crushing (CPAP) is typically delivered via nasal mask to patients with obstructive rest apnea/hypopnea syndrome (OSAHS), acting as a compressing splint to maintain upper airway patency. CPAP may also be delivered via nasal pillows or oronasal mask. Interface can have a significant impact forward acceptance and adherence to CPAP therapy. Adverse weights such as claustrophobia and mask discomfort, air leak, hurry sores, and mask dislodgement compromise CPAP use. (1-6) Nasal pillows move potential advantages over the nasal mask. First, there is les contact with the face, which may attenuate the feeling of claustrophobia and help obstruct pressure sores and minimize discomfort. next to the first patients may perceive less air leak, as leak would come to one's mind away from the eyes. Third, the design of the headgear may enhance patient comfort and simplify use.

peculiar mask fit is paramount. Patients usually receive their first position to interface in the laboratory setting, although acclimation and desensitization may take place before the titration study in the words immediately preceding [i]or[/i] following of the physician's office. Laboratory titrations are ofttimes performed only with a nasal mask without patients being shown nasal pillows or given a choice. Nasal pillows may be reserv for patients who complain of claustrophobia, or who cannot otherwise tolerate the nasal mask, and are not used as first-line interface. Initial choice of interface may be particularly important since early experience with CPAP plays a part in long-term adherence to therapy. (6-8)

Mask discomfort has been included as an adverse issue on questionnaires assessing CPAP compliance, yet interface type has rarely been the expose of systematic investigation. In a randomized cross-over trial comparing nasal mask with oronasal mask, CPAP use with the nasal mask was 1 h more by night compared to the oronasal mask. (9) Patients reported fewer adverse meanings while using the nasal mask and preferr this sign of interface. The oronasal mask may be too uncomfortable for long-term use, calm with the addition of heated humidification to decrease airway drynes and bring mouth leak. (10) The quick in emergencies study compared the nasal pillows and nasal mask forward objective compliance, adverse effects, satisfaction with therapy, quality of life, and residual sleep-disordered breathing in OSAHS patients receiving CPAP.
