We investigated the blood oxygen transport properties of the semi-fossorial Sundevall's Jird () using the mixing method to trace the oxygen-hemoglobin dissociation curve. Under standard conditions (pH 7.37; T 37 掳C; CO40 mmHg), Paveraged 42 mmHg and the Bohr factor 0.6. Both values are ...
a cornerstone element in its definition. Numerous indices have been used to describe this hypoxemia, such as the arterial to alveolar O2difference, the intrapulmonary shunt fraction, the oxygen index and the PaO2/FIO2ratio. Of these different indices the PaO2/FIO2ratio has been adopted for routine...
Dependency on acid-base status of oxyhemoglobin dissociation and 2,3-diphosphoglycerate level in human erythrocytes. II. In vivo studies. The intraerythrocytic level of 2,3-diphosphoglycerate and the oxygen affinity of hemoglobin in the red cell are shown to be strongly dependent on the intra.....
cells occur in individuals living at higher altitudes, such as the increase in the levels of 2,3-diphosphoglycerate (2,3-DPG), a chemical compound found inside the red blood cell, whose function is to reduce hemoglobin's affinity for oxygen in order to facilitate its release into tissues20...
When arterial oxygen (O2 ) levels fall, they evoke a rise in minute ventilation that mirrors the O2 hemoglobin dissociation curve. When activated, they ... BD Johnson,MJ Joyner - 《Jacc》 被引量: 5发表: 2013年 A left shift in the oxyhaemoglobin dissociation curve in patients with severe ...
From the oxygen hemoglobin dissociation curve, the following can be seen: Lungs: Partial pressure of oxygen is ___ mmHg Hemoglobin is ___ % saturated Tissues:. Partial pressure of oxygen is ___ mmHg Hemoglobin is ___ % saturat Choose the correct answer: At the lungs...

haemoglobin,Hb,hemoglobin- a hemoprotein composed of globin and heme that gives red blood cells their characteristic color; function primarily to transport oxygen from the lungs to the body tissues; "fish have simpler hemoglobin than mammals" ...
oxygen deliveryp50radiotherapysquamous cell carcinomaHypoxia was identified many years ago as a crucial cause of radioresistance in tumours and an association between haemoglobin concentration and radiation response has been established, especially in patients with squamous cell carcinoma. The explanation for ...
It is also important to recall that the hemoglobin dissociation curve shows hemoglobin to be 100% saturated when the partial pressure of arterial oxygen (PaO2) is approximately 80 mmHg. Under conditions of complete saturation, as is the case with 100% oxygen administration under normobaric conditions...
