Therefore, your PR interval may or may not be short and I wouldn't worry until you receive a full report. The PR interval is short in children and lengthens as we get older. A normal value in adults is 120 to 200 milliseconds. It is however shorter than 120ms in approximately 2 to 4% of the adult population.
It is SaO2 that measures oxygen saturation of hemoglobin, and it should be clear that it depends on the partial pressure of arterial oxygen. If PaO2 drops, there's less dissolved oxygen, and therefore less saturation of hemoglobin with oxygen.
Best Answer: CO2 is just Carbon Dioxide. Its the identifier for that gas. PCO2 is partial pressure of carbon Dioxide. This is usually a reading from a blood gas. It represents the amount of CO2 on the hemoglobin of the blood.Normal for an adult is 35-45mmHg Some times medical professional will refer to the PCO2 as their CO2 as in whats his CO2 level.CO2 readings can be obtained from blood, breath or perspiration just to name a few.t represents the amount of CO2 on the hemoglobin of the blood.
