Normal CO2 in the blood is the same as Normal PH. Ph is 7.35-7.45 CO2 is 35-45
95 or better
Decreasing spo2 signifies - decreased efficiency of lungs to absorb enough oxygen, required to have normal gaseous exchange.
CO2 regulates the body breathing functions. The normal range is 23 to 32. A level of 31 is within the normal range. High levels of CO2 could indicate a breathing problem.
SPO2 or pulse oximetry
92%
It is about 70 to 75 for a full term healthy newborn during the first 1-7 days
CO2 in the blood stream can be measured from bicarbonate in the blood or pCO2 (partial pressure). Normal CO2 measured from bicarbonate is 22-28 mEq/L Normal pCO2 is 35-45 mmHg
Pulse 120 to 150, SpO2 97% (SpO2= saturation derived from a pulse oximeter, a 2 wavelength, red and infrared, non-invasive probe). The heartrate will change as the infant ages, slowing down, while the oxygen level should remain constant throughout adulthood. An SpO2 of 97% is technically as high as it can go on room air, as there is a normal 3% anatomical shunt. This can however be increased if there is exposure to CoHb (Carbon Monoxide) which has an affinity for the heme ring of the red blood cell 210-240 times that of oxygen. Pulse oximetry has limitations and cannot differentiate between oxyhemoglobin and carboxyhemoglobin. That requires photospectronomy.
Since the normal SpO2 max is ~98%, due to physiological demands/metabolism, it would be the accuracy of the equipment that produced a 100% reading. Typically, pulse oximitry has an accuracy of +/- 2%.
