Trial Outcomes & Findings for Sleep-Disordered Breathing in Chronic SCI (NCT NCT02176928)

NCT ID: NCT02176928

Last Updated: 2020-11-02

Results Overview

Paced Serial Addition Test (PASAT) measures divided attention and memory. PASAT has a total score ranging from 0 to 60 with the lower scores indicate greater impairment of attention.

Measure
AutoPAP
PAP treatment will be delivered for four months by an auto-titrating device (IntelliPAP AutoAdjust®). These devices automatically set the level of delivered pressure to ensure upper airway patency, to treat detected apneas and hypopneas. AutoPAP: PAP will be delivered by an auto-titrating device (IntelliPAP AutoAdjust®). These devices automatically set the level of delivered pressure to ensure upper airway patency, to treat detected apneas and hypopneas. AutoPAP treatment 7 nights a week for four months (16 weeks).
Sham PAP
Sham PAP treatment will be delivered for four months by an auto-PAP device (IntelliPAP AutoAdjust®) that is set to a fixed low pressure of 3 cmH20 without an ability to titrate according to detected respiratory events. Sham PAP: Sham PAP treatment will be delivered by an auto-PAP device (IntelliPAP AutoAdjust®) that is set to a fixed low pressure of 3 cmH20 without an ability to titrate according to detected respiratory events. The pressure is too low to eliminate respiratory events and serves as sham or sub-therapeutic PAP. Sham PAP treatment 7 nights a week for four months (16 weeks)./
