Abstract:
An important property of blood is its degree of acidity and alkalinity which is referred to as acid-base balance. The acidity or alkalinity of the blood is indicated on the pH scale. The blood pH has a serious effect on all of the body’s systems and the body uses different mechanisms to control the blood’s acid-base balance. Acid-base imbalances result primarily from metabolic or respiratory failures, both imbalances cause changing in the normal range of CO2 in the blood. The concentrations of oxygen and carbon dioxide from the exhaled breath were used to evaluate the pH of the blood. The results show the relation between concentration of the exhaled CO2 and the blood acid-base pH; decreasing CO2 causes the blood to be alkaline, while increasing CO2 leads the blood to become acidic.
