Arterial oxygen desaturation during esophagogastroduodenoscopy.

This prospective study evaluated the incidence and severity of arterial oxygen desaturation during esophagogastroduodenoscopy (EGD) and assessed clinical factors in relation to arterial oxygen desaturation. Following pulmonary function testing, 192 patients underwent elective EGD with continuous recording of arterial oxygen saturation (SaO2). 62 patients (32.3%) showed arterial oxygen desaturat...

Oxygen desaturation after dental anaesthesia.

The incidence of oxygen desaturation (less than 91%) was measured by pulse oximetry during recovery from outpatient dental anaesthesia in 120 ASA grade I and II children. Alternate cases were given supplementary oxygen 5 litre min-1 by mask. Eighteen of 60 children (30%) given air and 14 of 60 (23%) given oxygen exhibited desaturation (P greater than 0.05). Desaturation was more likely to occur...

Oxygen desaturation during fiberoptic bronchoscopy.

A prospective study was performed to detect oxygen saturation (SaO2) during and following fiberoptic bronchoscopy (FOB) in 50 patients. Twenty-five patients (group 1) underwent the procedure without and 25 (group 2) with supplemental oxygen. The SaO2 declined from the baseline value of 96.4% to 92.08% in group 1 and to 94.88% in group 2 after bronchoscopy alone. The decline was also noted when ...

Evaluating predictions of critical oxygen desaturation events.

This paper presents a new approach for evaluating predictions of oxygen saturation levels in blood ( SpO2). A performance metric based on a threshold is proposed to evaluate  SpO2 predictions based on whether or not they are able to capture critical desaturations in the  SpO2 time series of patients. We use linear auto-regressive models built using historical  SpO2 data to predict critical desa...
