Official title
Comparison Between CPAP and BiPAP for Management of Sleep Disordered Breathing in Cervical Spinal Cord Injury Patients: a Pilot Randomized Controlled Study
Overview
Sleep-disordered breathing (SDB) is common in individuals with cervical spinal cord injuries, with studies suggesting prevalence rates ranging from 27% to 62%. The condition often leads to daytime sleepiness, fatigue, and poor participation in rehabilitation. Positive airway pressure therapy can be used to treat the condition; however, some individuals find continuous positive airway pressure (CPAP), which applies the same pressure during inhalation and exhalation, difficult to use. Bilevel positive airway pressure (BiPAP) offers different pressures for inhalation and exhalation, which may be more comfortable and potentially improve adherence in this patient population. However, limited evidence compares CPAP and BiPAP in individuals with cervical spinal cord injuries. This pilot study will enroll 32 adult participants with cervical spinal cord injuries who have moderate to severe SDB (defined as an AHI of 15 events/hour or greater). Participants will be randomly assigned to either CPAP or BiPAP therapy for 4 weeks. Device usage per night will be measured, and data on daytime sleepiness, fatigue, and sleep quality will be collected at baseline, 2 weeks, and 4 weeks. The investigators aim to determine whether BiPAP improves adherence and symptoms compared to CPAP in this patient population.
Interventions
- Device CPAP
Participants randomized to this group will receive auto-CPAP therapy. The device will be initiated by a respiratory therapist at GF Strong Rehabilitation Centre. Settings will be adjusted to achieve a device efficacy index \< 5 events per hour. - Device BiPAP
Participants will receive BiPAP S mode therapy for 4 weeks. The device will be initiated by a respiratory therapist at GF Strong Rehabilitation Centre with initial settings of IPAP 8 cmH2O and EPAP 3 cmH2O. Settings will be modified to a maximum tolerated level to achieve a tidal volume of 8 mL/kg ideal body weight and SpO2 \> 95%. Overnight oximetry will be performed to ensure at least 4 hours of device use, and settings will be adjusted to achieve a DEI \< 5 events per hour.
Primary outcome measures
