What happens if the arterial blood pH is 7.55?
This is too high, a situation called alkalemia. This will distort the ability of the blood to transport carbon dioxide and oxygen as well as alter the balance of electrolytes. If left untreated, alkalemia can be fatal.
What is meant by physiological acidosis when the blood pH is between 7 and 7.35?
The normal ph of arterial blood is 7.4, that of venous blood and IF is 7.35, and that of ICF averages 7.0. The lower pH in cells and venous blood reflects their greater amounts of acidic metabolites and carbon dioxide, which combines with water to from carbonic acid, H2CO3. Whenever the pH of arterial blood rises above 7.45, a person is said to have alkalosis or alkalemia. A drop in arterial pH to below 7.35 results in acidosis or academia. Because pH 7.0 is neutral, chemically speaking 7.35 is not acidic. However, it is a higher-than -optimal H+ concentration for most cells, so any arterial pHbetween 7.35 and 7.0 is called physiological acidosis.
What does it mean when your blood is alkaline?
pH is a measure of alkalinity (base) and acidity. Normal blood pH is between 7.35 and 7.45. When your blood pH is above 7.45 then you have alkaline blood. This is also called alkalemia. Your body can compensate for an increase in base or acid. Stomach acid neutralizes bases and your blood has a lot of HCO3 (bicarbonate) that can buffer, or resist, changes in pH up or down.
