Oxyhemoglobin desaturation definition
WebThe severe oxyhemoglobin desaturation is not attributed to an increased methemoglobin concentration, because thiopental is not known to be an oxidant stress. In the second occasion, he developed unconsciousness, apnea, and a decrease of Spo 2 to 79% after intravenous lidocaine. WebHypopneas are events characterized by reduced airflow or effort sufficient to cause either arousal or desaturations. Unfortunately, there is considerable variability among sleep laboratories regarding the duration or severity required to score hypopneas and no universally accepted definition exists.
