Pulse transit time in pregnancy: a new way to diagnose and classify sleep disordered breathing?

摘要

Study ObjectivesThere are significant discrepancies between the prevalence of snoring and that of objectively defined sleep disordered breathing among pregnant women, suggesting subtle airflow limitations that may not be captured by conventional scoring. This study examined the performance of pulse transit time, an indirect measure of arterial stiffness and sympathetic activation, in pregnancy.
