Sleep Apnea01:21

Sleep Apnea

833
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.
The condition is more prevalent among...

Assessment of Ventilation
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.

Respiratory Depth
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:

Area of Science:

  • Obstetrics and Gynecology
  • Sleep Medicine
  • Maternal-Fetal Medicine

Background:

  • Sleep disordered breathing (SDB) is increasingly recognized as a potential contributor to adverse pregnancy outcomes.
  • The Nulliparous Pregnancy Outcomes Study Monitoring Mothers-to-be (nuMoM2b) cohort provides a unique opportunity to investigate SDB in pregnancy.
  • Understanding the link between SDB and pregnancy complications is crucial for maternal and infant health.

Purpose of the Study:

  • To determine if sleep disordered breathing during pregnancy is a risk factor for adverse pregnancy outcomes.
  • To analyze the relationship between SDB and specific outcomes including preeclampsia, gestational hypertension, gestational diabetes mellitus, fetal growth restriction, and preterm birth.

Main Methods:

  • Prospective cohort study of 10,037 nulliparous women.
  • Sleep disordered breathing substudy recruited 3702 women.
  • Objective, overnight in-home sleep tests performed at two gestational periods (6-15 weeks and 22-31 weeks).

Main Results:

  • Objective sleep data obtained from 3261 women at the first visit (88.1% of attempted).
  • Objective sleep data obtained from 2511 women at the third visit (87.6% of attempted).
  • Basic characteristics of the substudy cohort are detailed in this methods article.

Conclusions:

  • The substudy was designed to investigate the relationship between sleep disordered breathing and pregnancy outcomes.
  • This research addresses critical questions regarding SDB's impact on maternal and child health, including preeclampsia risk.
