Participant Flow

The study has been terminated due to low enrollment after only 3 participants were randomized. Results will not be analyzed owing to the small number of participants to be randomized to receive aPAP (the intervention) or no aPAP (standard of care treatment).

32 participants provided informed consent to participate. They underwent an obstructive sleep apnea (OSA) risk assessment questionnaire. Those screening as high risk for OSA underwent home sleep apnea testing (HSAT). Those screening as positive on the HSAT, which was defined as an apnea hypopnea index (AHI) \>= 10 OR an AHI \>= 5 with oxygen desaturation index \>= 5, were randomized to receive aPAP or not. Of the 32 participants, only 3 met criteria for enrollment in the randomization phase.

PRIMARY outcome

Timeframe: 1 day

Population: Of two mothers randomized to aPAP therapy, one required pre-term induction of labor for maternal safety for preeclampsia with severe features. This fetus experienced in-utero fetal demise, so birth weight was not obtained.
