Validation of a new unattended sleep apnea monitor using two methods for the identification of hypopneas.

ABSTRACT:

Study objectives

The objective of the present study was to evaluate the accuracy of a home sleep apnea test (HSAT), MATRx plus (Zephyr Sleep Technologies, Calgary, Alberta, Canada), in identifying apneas and hypopneas and estimating indices of obstructive sleep apnea (OSA).

Methods

Individuals with suspected OSA underwent a one-night study wearing both HSAT and polysomnogram (PSG) sensors. The results provided by the overnight HSAT were compared with those from the simultaneously recorded PSG. The PSG data were scored manually, and the HSAT data were analyzed automatically using both preceding peak (PP) and moving average window (MW) methods for determining the reference oxyhemoglobin saturation (O₂ Sat). Accuracy of the HSAT in detecting individual apneic and hypopneic even
