ABSTRACT

PURPOSE: High-resolution pulse oximetry (HRPO) may provide an inexpensive and simple screening option for sleep disordered breathing (SDB), which could be critical in rural areas with limited health resources and specialized care. Our team hypothesized that applying this technology to a broad cohort of rural hospitalized patients would show similar congruence to previous urban studies comparing HRPO to wearable sleep monitors.

METHODS: This retrospective study was conducted at West Virginia University Hospital and compared indices obtained from HRPO to those obtained from a Type III wearable sleep monitor (PM) on the same night.

RESULTS: A total of 365 individuals were evaluated. The mean index of oxygen desaturation (18.8 ± 19.3 events/h) of HRPO was slightly higher than the mean index of respiratory events (16.0 ± 18.1 events/h, p ≤ 0.001) of PM. ROC curves were developed for apnea severity thresholds predicted by the screening program. AUC values ​​for all three cutoffs were greater than 0.92 and for a Respiratory Index (REI) ≥ 30 was 0.965. Indices of PM and HRPO showed concordance those with screening suggestive of moderate to severe disease.

CONCLUSION: This study demonstrates that the use of HRPO in screening for SDB in hospitalized patients from rural communities is as accurate as PM and can serve as a simple, inexpensive tool to address inequalities in sleep status in these regions of significant health inequality. Our data extend previous findings by applying HRPO to a larger hospital cohort with high prevalence of cardiopulmonary disease.
