Adequate organ function requires adequate provision of cells with oxygen (O2). The driving force for O2-diffusion from ambient air to its site of consumption in cell mitochondria is the oxygen partial pressure (pO2) gradient along this pathway. After uptake in the lungs, O2 transport in blood...
Recent progress has been made in the identification and implementation of best transfusion practices on the basis of evidence-based clinical trials, published clinical practice guidelines, and process improvements for blood use and clinical patient outcomes. However, substantial variability persists in trans...
Most of the oxygen that is carried by blood is bound to hemoglobin found in red blood cells (erythrocytes). The binding of oxygen to hemoglobin (HbO2) is determined by the partial pressure of oxygen (PO2) and the affinity of the hemoglobin for oxygen, as shown in the figure to the ...
In various pathological conditions the cardio-respiratory system may be unable to meet the oxygen demand of the tissues. Thus, manipulation of the bulk transport of oxygen (TO2) is a frequent intervention in the intensive care patients. However T02 is only one part of the processes involved in...
The primary goal of the cardio-respiratory system is to maintain an adequate flux of oxygen to the tissues to meet their metabolic demands. The flux of oxygen from the heart through the arterial circuit can be measured relatively easily and is referred to as oxygen transport (TO2). That frac...

The study was designed to investigate the age-related increase in maximal oxygen uptake with special reference to the other physiological parameters (ventilation, pulmonary diffusing capacity, cardiac output etc.). 77 normal boys aged 10–18 years were tested by the progressive loading method on a ...
