pulse oximeter oxygen saturation in prediction of arterial oxygen saturation in liver transplant candidates
results roc-derived spo2 threshold of ≤ 94% can predict hypoxemia (pao2 < 60 mmhg) with a sensitivity of 100% and a specificity of 95%. furthermore, there are associations between the roc-derived spo2 threshold of ≤ 97% and detection of hypoxemia (pao2 < 70 mmhg) with a sensitivity of 100% and a specificity of 46%. the accuracy of pulse oximetry was not affected by the severity of liver disease...
متن کاملPulse Oximeter Oxygen Saturation in Prediction of Arterial Oxygen Saturation in Liver Transplant Candidates
BACKGROUND Liver transplant is the only definitive treatment for many patients with end stage liver disease. Presence and severity of preoperative pulmonary disease directly affect the rate of postoperative complications of the liver transplantation. Arterial blood gas (ABG) measurement, performed in many transplant centers, is considered as a traditional method to diagnose hypoxemia. Because A...
متن کاملDo changes in pulse oximeter oxygen saturation predict equivalent changes in arterial oxygen saturation?
INTRODUCTION This study investigates the relation between changes in pulse oximeter oxygen saturation (SpO2) and changes in arterial oxygen saturation (SaO2) in the critically ill, and the effects of acidosis and anaemia on precision of using pulse oximetry to predict SaO2. PATIENTS AND METHODS Forty-one consecutive patients were recruited from a nine-bed general intensive care unit into a 2-...
متن کاملZero Oxygen Saturation in Pulse Oximeter: Need for Clinical Correlation
Sir, I would like to share an unusual incident, which had happened recently in our operation theater. This event had occurred while conducting spinal anesthesia for a 28-year-male patient with an inguinal hernia for meshplasty. His preoperative anesthetic evaluation and investigations were unremarkable. In the operating room, the blood pressure (BP) cuff and pulse oximeter were applied in the s...
متن کاملCerebral arterial oxygen saturation measurements using a fiber-optic pulse oximeter.
BACKGROUND A 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 brain tissue. METHODS Short-duration measurements were made in six patie...
