Objective.
To assess the diagnostic ability of WristOx 3100 using its three different recording settings in patients with suspected obstructive sleep apnea syndrome (OSAS).
Methods.
All participants (135) performed the oximetry (three oximeters WristOx 3100) and polysomnography (PSG) simultaneously in the sleep laboratory.
Both recordings were interpreted blindly.
Each oximeter was set to one of three different recording settings (memory capabilities 0.25, 0.5, and 1 Hz).
The software (nVision 5.1) calculated the adjusted O2 desaturation index-mean number of O2 desaturation per hour of analyzed recording ≥2, 3, and 4% (ADI2, 3, and 4).
The ADI2, 3, and 4 cutoff points that better discriminated between subjects with or without OSAS arose from the receiver-operator characteristics (ROCs) curve analysis.
OSAS was defined as a respiratory disturbance index (RDI) ≥ 5.
Results.
101 patients were included (77 men, mean age 52, median RDI 22.6, median BMI 27.4 kg/m2).
The area under the ROCs curves (AUC-ROCs) of ADI2, 3, and 4 with different data storage rates were similar (AUC-ROCs with data storage rates of 0.25/0.5/1 Hz: ADI2: 0.958/0.948/0.965, ADI3: 0.961/0.95/0.966, and ADI4: 0.957/0.949/0.963, P NS).
Conclusions.
The ability of WristOx 3100 to detect patients with OSAS was not affected by the data storage rate of the oxygen saturation signal.
Both memory capacity of 0.25, 0.5, or 1 Hz showed a similar performance for the diagnosis of OSAS.
