Insights

Infant sleep apnea, including central and obstructive types, is common. Sleep-disordered breathing in infants disrupts sleep patterns, particularly reducing rapid eye movement (REM) sleep.

Area of Science:

  • Pediatric Sleep Medicine
  • Neonatology
  • Respiratory Physiology

Background:

  • Sleep apnea is frequently observed in infants, yet comprehensive data on its prevalence and spectrum are limited.
  • Understanding the variations in apnea and associated upper airway obstruction is crucial for infant health.

Purpose of the Study:

  • To quantify the amount and range of apnea in infants referred to a sleep disorders unit.
  • To investigate the relationship between sleep-disordered breathing, upper airway obstruction, and infant sleeping patterns, specifically REM sleep.

Main Methods:

  • Polysomnographic studies were conducted on 49 infants.
  • Apnea, upper airway obstruction (mixed apnea), and sleeping patterns were analyzed.
  • Infants were categorized into two groups based on apnea severity and obstruction levels.

Main Results:

  • Central apnea was present in all infants, with varying amounts.
  • Mixed apnea (upper airway obstruction) was found in 36 infants, with 16 exhibiting significant obstruction.
  • Group I infants (obstruction or high central apnea) showed significantly less REM sleep compared to Group II.

Conclusions:

  • Sleep-disordered breathing is a significant issue in infants.
  • Infants experiencing sleep-disordered breathing exhibit notable disruptions in their sleep architecture.
  • Reduced REM sleep is associated with sleep-disordered breathing in this infant cohort.

Breathing

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...
Alterations in Respiration II01:30

Alterations 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...
Insufficient Sleep and Sleep Deprivation01:13

Insufficient Sleep and Sleep Deprivation

Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.
Sleep deprivation is a more severe form of sleep loss...
Sleepwalking and Sleep Talking01:17

Sleepwalking 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...
REM Sleep Behavior Disorder01:15

REM 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.
RBD is significantly associated with...
Sleep Apnea01:21

Sleep 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.
The condition is more prevalent among...
