BACKGROUND Rapid sequence induction may be associated with hypoxemia. The purpose of this study was to investigate the possible difference in desaturation during rapid sequence induction in overweight patients using either succinylcholine or rocuronium. METHODS Sixty patients with a body mass index (BMI) between 25 and 30 kg/m², American Society of Anesthesiologists class I or II, undergoing ...

This paper will design a non-invasive pulse oximeter using the ADuC842 microcontroller. A pulse oximeter is a medical device that indirectly monitors the oxygen saturation of a patient's blood and heart rate. The hardware has been developed for the pulse oximeter and programming/coding has been done for calculating blood oxygen saturation and pulse rate of a patient. The results are displayed o...

The present study was undertaken in an attempt to contribute to the solution of the problem of the effect of rapid heart rate on the oxygen satu'ration of the arterial blood. In 1921 Barcroft, Bock and Roughton (1) reported that they had found normal saturation of the arterial blood in a patient during an attack of paroxysmal-tachycardia. Carter and Stewart (2) later reported a case in which th...

Regional coronary venous oxygen saturation and myocardial oxygen tension (Po2) in isolated dog hearts were measured using two different methods—a new technique of microscopic oximetry and an improved oxygen electrode. Both methods yielded similar results. In studies of the isolated perfused dog heart developing a constant left ventricular systolic pressure, mean coronary venous oxygen saturatio...

background: the use of intravenous sedatives is common in gastrointestinal endoscopy. this study is to evaluate the safety and ef_cacy of propofol and/or midazolam in induction of proper sedation in esophagogastroduodenoscopy (egd) compared with a control group, which does not receive sedation for egd. â  methods: four groups (a, b, c and d) of 30 patients each for whom egd had been indicated w...

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...

Background: Poisoning with carbon monoxide occurs occasionally worldwide, and the gold diagnostic standard is to measure carboxyhemoglobin level in the blood. This study investigated the correlation between carboxyhemoglobin and the end-tidal carbon dioxide levels in 50 patients with carbon monoxide poisoning. Methods: We recruited 50 volunteer patients who had been admitted to the Emergency S...

Introduction: Several pathological conditions can reduce blood supply to the organs, among which burns can be mentioned. By developing the volume depletion and reducing the cardiac contractility, burns can cause hypoperfusion. Further, in ICUs, since the finger pulse oximetryis commonly used instead of the measurement of the nasal alar oxygen saturation, the use of finger probe restricts pulse ...
