Blood oxygen transport and tissue oxygenation were studied in 28 calves from the Belgian White and Blue breed (20 healthy and 8 hypoxaemic ones). Hypoxaemic calves were selected according to their high respiratory frequency and to their low partial oxygen pressure (PaO2) in the arterial blood. Venous and arterial blood samples were collected, and 2,3-diphosphoglycerate, adenosine triphosphate, ...

We report a case of coarctation of aorta with previous caesarean section who underwent elective caesarean section under combined spinal epidural anaesthesia (CSEA). By continuous monitoring of oxygen saturation in lower limb, perfusion of the body below coarctation site was assessed. Good oxygen saturation in the lower limbs meant good foetal perfusion and good perfusion of vital organs. Thus o...

Cardiovascular complications are common in fibrosing alveolitis, but there have been few physiological studies of the pulmonary circulation in this condition, and those that have been carried out have usually depended on right heart catheterisation. This paper reports non-invasive measurements of effective pulmonary blood flow, oxygen uptake, pulmonary arteriovenous oxygen content differences, ...

A pulse oximeter is a medical device that indirectly monitors or measure the oxygen saturation of a patient's blood (as opposed to measuring oxygen saturation directly through a blood sample) and changes in blood volume in the skin, producing a photoplethysmogram. The pulse oximeter may be included into a multi parameter patient monitor. This also displays the pulse rate. There are many portabl...

OBJECTIVE To evaluate the immediate effects of red blood cell transfusion on central venous oxygen saturation and lactate levels in septic shock patients with different transfusion triggers. METHODS We included patients with a diagnosis of septic shock within the last 48 hours and hemoglobin levels below 9.0 g/dL Patients were randomized for immediate transfusion with hemoglobin concentration...
