The impact of pregnancy on sleep quality and sleep disordered breathing (SDB) is of interest due to concerns of an impact on maternal, intra-uterine and neonatal health. The SDB sub-study of the Nulliparous Pregnancy Outcomes Study (NuMoM2b) provided a large cohort of single gestational women who underwent home sleep apnea testing (HSAT) to evaluate for SDB. To evaluate changes in sleep during pregnancy, a secondary analysis of this data utilizing cardiopulmonary coupling (CPC) was performed.
The sleep parameters of main interest the apnea hypopnea index (AHI), the sleep quality index (SQI) and sleep duration were all adversely impacted as gestation progressed (p<0.001).
The SleepImage method uses simple portable photoplethysmography and is low-cost, it is more convenient than the conventional method (HSAT) and offers the opportunity to monitor sleep during pregnancy as multiple tests can be conducted in a patient-friendly sleep environment, such as the patient’s own home.
