Oxyhemoglobin desaturation during sleep
WebMany individuals with COPD are hypoxemic and have waking arterial oxygen tensions at or near the steep portion of the oxyhemoglobin dissociation curve. Accordingly, a decrease of alveolar ventilation will cause greater oxygen desaturation in these individuals than in normal individuals. ... Oxygen desaturation during sleep in COPD is also ... WebMar 24, 2024 · Sleep apnea — a condition in which breathing stops and starts many times during sleep. Some medicines that can cause slow, shallow breathing can lead to hypoxemia. These include certain opioid pain relievers and medicines that prevent pain during surgery and other procedures, called anesthetics.
