Comparing 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...

Physiol. 206(4) : 858-866. rg64.-The effect of changes in blood flow and of blood oxygen tension on oxygen uptake of the in situ gastrocnemius-plantaris muscle group of the dog was examined. Oxygen uptake by resting muscle was not altered by changes in blood...
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...
متن کاملPilot investigation of photoplethysmographic signals and blood oxygen saturation values during blood pressure cuff-induced hypoperfusion
Photoplethysmography (PPG) is a non-invasive electro-optical technique widely used in the monitoring of the pulsations associated with changes in blood volume in a peripheral vascular bed. The technique is based on the absorption properties of vascular tissue when it is transilluminated by light. Photoplethysmography is also used in the estimation of arterial blood oxygen saturation ðSpO2Þ by p...
