ABSTRACT
For obtaining P50 in mongrel dogs at normal body temperature (37degrees C), pH(7.4) and PaCO2 (40 mmHg), we performed arterial blood gas analysis in 14 mongrel dogs by using ABL 30 blood gas analyzer ( Radiometer, Copenhagen, Denmark) after inhalation of various concentration of oxygen. The oxyhemoglobin dissociation curve was made by plotting of arterial O2 saturation against each PaO2, and P50 was obtained by using linear regression equation. The result shows that P50 in mongrel dogs is 28.5+/-0.8 mmHg (mean+/-DS).
