a significant reduction in arterial blood oxygen saturation during fiberoptic bronchoscopy has been proved but it is not yet known whether all patients need supplemental oxygen during this procedure. the aim of study is to examine the relationship between peak expiratory flow rate (pefr) before bronchoscopy and oxygen desaturation during bronchoscopy. measurement of pefr (% predicted) performed...

introduction: hypoxemia can occur during upper gastrointestinal endoscopy with or without pharmacological sedation. pulse oximetry saturation (spo2) levels were assessed in patients attending for routine unsedated diagnostic upper gastrointestinal endoscopy to identify factors associated with oxygen desaturation. methods: a total of 300 patients who underwent upper gastrointestinal endoscopy wi...

OBJECTIVES To measure the incidence of cerebral desaturation during high-risk cardiac surgery and to evaluate strategies to reverse cerebral desaturation. DESIGN Prospective observational study followed by a randomized controlled study with 1 intervention group and 1 control group. SETTING Tertiary care center specialized in cardiac surgery. PARTICIPANTS All patients were scheduled for hi...

OBJECTIVE Despite advances in anesthetic technique, the incidence of perioperative desaturation in general anesthesia has remained high. Knowledge on factors associated with intraoperative desaturation is relatively scanty. The purpose of the present study was to investigate the distribution of time dependent intraoperative desaturation and factors predicting perioperative desaturation. MATER...

We present the cases of three children with patent ductus arteriosus (PDA), pulmonary arterial hypertension (PAH), and desaturation. One of them had desaturation associated with atrial septal defect (ASD). His ASD, PAH, and desaturation improved after successful device closure of the PDA. The other two had desaturation associated with Down syndrome. One had desaturation only at room air oxygen ...

BACKGROUND Oxygen desaturation is not uncommon during bronchoscopy. We sought to identify factors predictive of desaturation during flexible bronchoscopy. METHODS Over eight months, we enrolled 137 randomly selected patients who were undergoing fiberoptic bronchoscopy at our medical center. The patients' oxygen saturation was monitored on their arrival and during the procedure by finger pulse...

Early experience with continuous monitoring of jugular venous oxygen saturation (SjvO2) suggested that this technology might allow early identification of global cerebral ischaemia in patients with severe head injury. The purpose of the present study was to examine the relationship between episodes of jugular venous desaturation and neurological outcome. One hundred and sixteen severely head-in...

BACKGROUND AND PURPOSE Wake-up stroke (WUS) represents a quarter of all ischemic strokes and may be a specific subgroup. Nocturnal desaturation secondary to sleep-disordered breathing is an independent risk factor for stroke, but the association between nocturnal desaturation and WUS remains unclear. We investigated the relationship between nocturnal desaturation using oxygen desaturation index...

BACKGROUND Oxygen desaturation during walking can have important consequence on prognosis of COPD patients. However, a standard 6-min walk test (6MWT), useful in detecting desaturation in COPD patients, can be difficult to execute in some settings of COPD management, as in the community healthcare service. We evaluated a new scoring system for the risk of oxygen desaturation during walking in C...
