OBJECTIVE To compare pH and PCO2 values of simultaneously obtained arterial, arterialized capillary, and venous blood samples and also to compare oxygen saturation (ASaO2) measured in arterial blood and oxygen saturation by pulse oximetry (PSaO2). METHODS Prospective study was done in the children admitted in the Pediatric Intensive Care Unit of Christian Medical College Hospital Vellore, req...

UNLABELLED Venoarterial extracorporeal membrane oxygenation (VA-ECMO) can be lifesaving in patients with cardiopulmonary collapse. However, observation studies have implied that oxygenated blood does not pass in a retrograde fashion from the VA-ECMO circuit to the aortic root and arch when the femoral artery (FA) is used. This study aims at accurately measuring the oxygen saturation in various ...

RATIONALE Hypoxemia is common during endotracheal intubation of critically ill patients and may predispose to cardiac arrest and death. Administration of supplemental oxygen during laryngoscopy (apneic oxygenation) may prevent hypoxemia. OBJECTIVES To determine if apneic oxygenation increases the lowest arterial oxygen saturation experienced by patients undergoing endotracheal intubation in t...

It is well recognized that air-absorption collapse of a iobe of a lung or a whole lung does not necessarily cause arterial anoxia. In the course of our investigation of the role of the anastomoses between the bronchial and pulmonary arteries described by Braus (1934), von Hayek (1940), Verloop (1948), Liebow, Hales, and Lindskog (1949), and Marchand, Gilroy, and Wilson (1950) in disease, we hav...

Case report An 88-year-old woman was admitted to the emergency department of our hospital with an itchy skin rash that developed while she was on antibiotics (quinolones), administered for an episode of acute cystitis, asthenia and fever. She was suspected to have an allergic reaction and treated with i.v. methylprednisolone 40 mg per day. After 24 hours, skin rash and fever had subsided and th...

This pilot investigation was undertaken to assess the performance of a novel fiber-optic cerebral pulse oximetry system. A fiber-optic probe designed to pass through the lumen of a cranial bolt of the type used to make intracranial pressure measurements was used to obtain optical reflectance signals directly from the brain tissue. Preliminary results from seven patients measured in the operatin...

introduction: one of the main complications of hemodialysis in patients with chronic renal failure is hypoxemia which is related to several factors including the type of filter. the aim of this study was to evaluate the hypoxemia levels in patients undergoing hemodialysis with focus on the type of filter. methods: in a crossover clinical trial, 29 patients from emodialysis ward of fatemieh hosp...

Digital pulse oximetry is a useful non-invasive tool to monitor oxygen saturation. However, it has its own limitation and cannot reflect the true arterial oxygen saturation in case of unstable haemoglobin. We report a Chinese girl having unstable haemoglobin presenting with incidental finding of low oxygen saturation measured by pulse oximetry, its value in identifying affected family members a...
