What is hypopnea?

Hypopnea refers to a condition characterized by a decrease in airflow during sleep, which can lead to a reduction in the oxygen saturation levels in the blood. This diminished airflow is significant because it can disrupt normal sleep patterns and lead to various health issues, such as sleep apnea. During hypopnea, breathing becomes shallow or very lightly reduced rather than being entirely absent, which distinguishes it from apnea, a complete cessation of breathing.

Recognizing hypopnea is crucial as it can contribute to fragmented sleep and a reduced quality of life, making early detection and treatment vital in sleep medicine. Understanding the implications of hypopnea aids in the diagnosis and management of sleep-related disorders.
