desaturation
Pronunciation: dee-sat-yur-AY-shun
Drop in blood oxygen saturation levels below acceptable thresholds, monitored continuously in NICU patients.
Full Definition
Desaturation refers to a decrease in oxygen saturation levels in the blood, typically measured via pulse oximetry. In neonatal care, desaturation events (often called 'desats') are closely monitored as they may indicate respiratory compromise, apnea, or other medical issues. Target oxygen saturation levels vary based on gestational age and clinical condition, with premature infants requiring careful balance to avoid both hypoxemia and hyperoxemia.
Usage
Usage note: Commonly shortened to 'desat' in clinical communication.
