Misunderstanding the arterial blood oxygen saturation
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...
متن کاملComparing the Effect of Simple Filtration Hemodialysis and Ultrafiltration Hemodialysis on Arterial Oxygen Saturation and Blood Pressure in Chronic Dialysis
Background and purpose: Hypoxemia and hypotension are important complications of hemodialysis in patients with chronic renal failure that are linked to several factors, including the type of filters used. The aim of this study was to compare the effect of simple filtration hemodialysis and ultrafiltration hemodialysis on blood pressure and blood arterial oxygen level. Materials and methods: In...
متن کاملArterial Blood Oxygen Saturation during Blood Pressure Cuff-induced Hypoperfusion
Pulse oximetry has been one of the most significant technological advances in clinical monitoring in the last two decades. Pulse oximetry is a non-invasive photometric technique that provides information about the arterial blood oxygen saturation (SpO2) and heart rate, and has widespread clinical applications. When peripheral perfusion is poor, as in states of hypovolaemia, hypothermia and vaso...
متن کاملpulse 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 کاملTHE EFFECT OF ARTERIAL O2 SATURATION AND HE ART RATE ON BLOOD PRESSURE DURING HYPOXIA
A periodic increase in blood pressure (BP) occurs during apneic episodes in patients with obstructive sleep apnea (OSA). Several factors including hypoxemia and an increase in heart rate (HR) were reported to be responsible for this increased BP. To examine the contribution of these two factors in increasing BP, 35 healthy male subjects (mean age±SD= 23.64±3.80) were studied in three experi...
