Accuracy of venous blood oxygen pressure depends on arterial blood oxygen pressure.
I read with interest the article by REES et al. [1]. Their data on 40 patients with chronic lung disease supports the use of peripheral venous blood for an estimate of the arterial oxygen tension (Pa,O 2) in a vast majority of patients. They also address this issue in a similar study [2]. They found that mean Pa,O 2 was not clinically larger than the peripheral venous oxygen tension (0.83¡4 mmH...
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 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 کاملEffect of aortic insufficiency on arterial blood pressure, coronary blood flow and cardiac oxygen consumption.
In patients with aortic insufficiency and without disease of the coronary ostia or arteries, the occurrence of chest pain having some or many of the characteristics of cardiac pain due to myocardial ischemia has been ascribed classically to a decrease in the coronary blood flow (1, 2), the aortic insufficiency presumably decreasing the coronary blood flow by lowering the mean aortic diastolic p...
متن کاملEffect on partial pressure of oxygen in arterial blood in percutaneous vertebroplasty.
BACKGROUND AND PURPOSE The purpose of this study is to estimate the change in partial pressure of oxygen (Pao(2)) during percutaneous vertebroplasty and also to examine the factors related to the change in Pao(2). MATERIALS AND METHODS We retrospectively reviewed preprocedural and postprocedural Pao(2) of 59 consecutive patients who underwent percutaneous vertebroplasty between November 2003 ...
