'''Periodic breathing''' is a respiratory pattern characterized by alternating periods of apnea or hypopnea (shallow breathing) and normal breathing, typically observed during sleep. This phenomenon is considered a normal variant in infants and can also be seen in adults, particularly at high altitudes or in individuals with certain medical conditions.

== Physiology ==

Periodic breathing results from fluctuations in the body's respiratory control system. These fluctuations can be influenced by factors such as chemoreceptor sensitivity, lung volume, and metabolic rate. The pattern may be exacerbated or triggered by specific situations or conditions, such as altitude, sleep, or certain medical disorders.

== Types of Periodic Breathing ==
There are two main types of periodic breathing:
'''[[Cheyne-Stokes respiration]]:''' This form of periodic breathing is characterized by a gradual increase and decrease in the depth and rate of breathing, followed by a period of apnea. Cheyne-Stokes respiration is commonly seen in patients with heart failure, stroke, or other neurological disorders.
'''[[Central sleep apnea]]:''' This type of periodic breathing occurs during sleep and is caused by a temporary disruption in the brain's signals to the muscles responsible for breathing. Central sleep apnea is often associated with conditions such as heart failure, obesity, or the use of certain medications.
== Clinical Significance ==
In most cases, periodic breathing is a benign and self-limiting condition. However, it can be a sign of an underlying medical disorder, such as:
* [[Heart failure]]
* [[Stroke]]
* [[Kidney failure]]
* [[High-altitude sickness]]
* Brain tumors or other neurological disorders
== Diagnosis ==
Periodic breathing is typically diagnosed through a combination of clinical history, physical examination, and diagnostic tests, such as:
'''[[Polysomnography]]:''' This overnight sleep study measures various physiological parameters, including brain waves, eye movements, muscle activity, and breathing patterns, to assess sleep quality and identify any sleep-related breathing disorders.
'''[[Pulse oximetry]]:''' This noninvasive test measures oxygen levels in the blood, which can help identify periods of hypoxia (low oxygen) associated with periodic breathing.
== Treatment ==
Treatment for periodic breathing depends on the underlying cause and the severity of the condition. In some cases, no treatment is necessary, while in others, addressing the underlying medical condition or making lifestyle changes can help alleviate symptoms. Treatment options may include:
* Oxygen therapy
* Continuous positive airway pressure (CPAP) therapy
* Medications to manage heart failure or other contributing conditions
* Lifestyle modifications, such as weight loss, exercise, and avoiding alcohol or sedatives
