desaturation


Also found in: Dictionary, Wikipedia.

de·sat·u·ra·tion

(dē'sat-yū-rā'shŭn),
1. The act, or the result of the act, of making something less completely saturated; more specifically, the percentage of total binding sites remaining unfilled; for example, when hemoglobin is 70% saturated with oxygen and nothing else, its desaturation is 30%. Compare: saturation (5).
2. The process or reaction of removal of two hydrogen atoms from a molecule, resulting in the formation of a double bond.

On physical examination, the on-call resident noted intermittent retractions with inspiratory stridor, and the patient demonstrated intermittent severe oxygen desaturations into the 70s.
Positive pressure was provided through hand-assisted ventilation which prevented the patient from desaturation due to partial inflow forced by positive pressure and partial flow through the upper airway.
Patients with AHI greater than 15.6 events per hour or in the DI4% tertile (more than 9.3 desaturations per hour) were approximately twice as likely (1.94 and 1.93 times, respectively) to have a more aggressive melanoma as were those with less severe sleep apnea, after adjustment for age, gender, body mass index, and melanoma location.
Lowering the oximetry threshold (2 desaturation clusters and 1 desaturation event <90%) improves sensitivity and negative predictive values to 86% and 90%, respectively.
(13) were reported that the frequency of nocturnal desaturation was significantly higher and the duration of desaturations was longer in the printers than in the controls.
Although, initial spontaneous and regular breathing may not reflect complete functional recovery, this may still prevent haemoglobin desaturation that would ensue if the patient remained apnoeic.
Similarly desaturation was observed in 85 cases in group-A (24%) as compared to 28 cases (8%) in group-B.
The time of desaturation was measured without the use of noninvasive mechanical ventilation.
Then, after checking for exact alignment between the two copies, experiment by decreasing the opacity of the top black and white layer to get a desired level of desaturation of the original color image as the result of combining the two versions of the same photograph.
Desaturation episodes are one of the main reasons for the development of complications associated with OSAS.
