High altitude periodic breathing
ICD-10 G47.32 is a billable code used to indicate a diagnosis of high altitude periodic breathing.
High altitude periodic breathing (HAPB) is a condition characterized by abnormal respiratory patterns that occur in individuals exposed to high altitudes, typically above 2,500 meters (8,200 feet). This phenomenon is often observed in individuals who ascend to high altitudes rapidly without proper acclimatization. The condition is marked by episodes of hyperventilation followed by periods of hypoventilation or apnea, which can lead to significant fluctuations in blood oxygen levels. HAPB is thought to be a response to hypoxia, where the body attempts to compensate for reduced oxygen availability. Symptoms may include sleep disturbances, daytime fatigue, and cognitive impairment. Diagnosis is often made through polysomnography, which reveals the characteristic breathing patterns during sleep. Management typically involves gradual acclimatization to altitude, supplemental oxygen, and in some cases, medications such as acetazolamide to enhance respiratory drive. Understanding HAPB is crucial for healthcare providers, especially in regions where high-altitude exposure is common, as it can mimic other sleep disorders like obstructive sleep apnea or central sleep apnea.
