Summary
Pregnancy alters respiratory function, increasing sleep disordered breathing risks. Respiratory physicians should consider sleep apnea in pregnant patients due to these physiological changes.
Area of Science:
- Obstetrics and Gynecology
- Pulmonology
- Sleep Medicine
Background:
- Pregnancy significantly alters respiratory physiology, especially in the third trimester.
- These changes can compromise respiratory function during sleep.
- Increased incidence of snoring suggests a rise in sleep disordered breathing.
Purpose of the Study:
- To examine physiological changes during pregnancy and their link to sleep disordered breathing.
- To summarize current knowledge on sleep disordered breathing in pregnant individuals.
Main Methods:
- Review of physiological changes in the respiratory system during pregnancy.
- Analysis of the relationship between these changes and sleep disordered breathing.
- Synthesis of existing literature on sleep disordered breathing in pregnancy.
Main Results:
- Pregnancy involves increased ventilatory drive, metabolic rate, and alveolar-arterial oxygen gradients.
- Reduced functional residual capacity and residual volume occur.
- Upper airway patency changes and increased snoring indicate higher obstructive sleep apnea/hypopnea syndrome risk.
Conclusions:
- Physiological adaptations during pregnancy predispose women to sleep disordered breathing.
- Sleep disordered breathing, including obstructive sleep apnea/hypopnea syndrome, is more common in pregnancy.
- Respiratory physicians must consider sleep disordered breathing in pregnant patients.

01:05Breathing
The process of breathing, inhaling and exhaling, involves the coordinated movement of the chest wall, the lungs, and the muscles that move them. Two muscle groups with important roles in breathing are the diaphragm, located directly below the lungs, and the intercostal muscles, which lie between the ribs. When the diaphragm contracts, it moves downward, increasing the volume of the thoracic cavity and creating more room for the lungs to expand. When the intercostal muscles contract, the ribs...
01:30Alterations in Respiration II
There are numerous types of normal and abnormal respiration. Based on ventilatory movements, breathing patterns are classified as regular, deep, or shallow. Examples include Biot's breathing, Cheyne-Stokes respiration, Kussmaul's breathing, hyperventilation, and hypoventilation. Each pattern is clinically significant and aids in evaluating patients.
In Biot's breathing, the respiratory rate and depth are irregular, alternating between periods of deep gasping and apnea. Common causes include...

01:17Other Pulmonary Disorders
Respiratory disorders encompass a range of conditions with varying levels of severity. Asthma, marked by chronic airway inflammation and hypersensitivity, is one such condition. It can lead to airway obstruction due to factors like bronchial spasms, mucosal edema, increased mucus secretion, or epithelial damage. Asthma triggers are diverse, ranging from allergens to emotional upset, and treatment focuses on both immediate relief through bronchodilators and long-term inflammation suppression.
01:17Sleepwalking and Sleep Talking
Somnambulism, commonly known as sleepwalking, involves individuals engaging in activities ranging from simple walking to more complex behaviors such as driving. Sleepwalking typically occurs during the slow-wave sleep stages 3 and 4 early in the night when the person is not dreaming, contradicting the myth that sleepwalkers are acting out their dreams.
Factors that increase the likelihood of sleepwalking include sleep deprivation and alcohol consumption. Contrary to common beliefs, it is safe...

01:15REM Sleep Behavior Disorder
REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.

01:21Sleep Apnea
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.
