Correct Answer: The blood is acidic. pH must be less than 7.0 for acidic to be true. The condition certainly is an acidosis.
Full Answer
A blood pH test is a normal part of a blood gas test or arterial blood gas (ABG) test. It measures how much oxygen and carbon dioxide is in your blood. Your doctor might test your blood pH as part of a regular health checkup or if you have a health condition.
A pH higher than 7 is alkaline or basic. This scale might seem small, but each level is 10 times bigger than the next. For example, a pH of 9 is 10 times more alkaline than a pH of 8. A pH of 2 is 10 times more acidic than a pH of 3, and 100 times more acidic than a reading of 4. So, what’s a normal blood pH?
A blood pH level that isn’t normal may be a sign you have slight imbalance or a health condition. In most cases, your blood pH will balance out once the cause goes away or is treated. You may need several tests to help your doctor find the best treatment for you. These include:
A pH below 7.35 indicates acidosis; thus a pH of 7.25 a sign of acidosis. Normal blood pH lies between 7.35 and 7.45. A pH of 7.55 indicates alkalosis. A patient has the following arterial blood gas results: pH 7.32; PaCO2 56 mm Hg; HCO3- 24 mEq/L.
Interpreting the results A pH of less than 7.35 indicates acidosis and a pH greater than 7.45 indicates alkalosis.
Example: a patient with a blood pH of 7.33 is slightlyAcidemic, i.e., on the acid side of the normal 7.4. If his PCO2 is 60 he has a strong Respiratory Acidosis accompanied by a partially compensating Metabolic Alkalosis of 6 mEq/L.
Alkalosis is excessive blood alkalinity caused by an overabundance of bicarbonate in the blood or a loss of acid from the blood (metabolic alkalosis), or by a low level of carbon dioxide in the blood that results from rapid or deep breathing (respiratory alkalosis).
Metabolic alkalosis is diagnosed by measuring serum electrolytes and arterial blood gases. If the etiology of metabolic alkalosis is not clear from the clinical history and physical examination, including drug use and the presence of hypertension, then a urine chloride ion concentration can be obtained.
A quick introduction to the pH scale The right pH levels are needed for good health. The pH scale ranges from 0 to 14. The readings are based around a pH of 7, which is neutral, like pure water: A pH below 7 is acidic. A pH higher than 7 is alkaline or basic.
Metabolic acidosis occurs when the blood is too acidic (pH below 7.35) due to too little bicarbonate, a condition called primary bicarbonate deficiency. At the normal pH of 7.40, the ratio of bicarbonate to carbonic acid buffer is 20:1. If a person's blood pH drops below 7.35, then he or she is in metabolic acidosis.
Alkalosis is characterized by a pH level of 7.45 or higher. While seemingly slight, these numerical differences can be serious. Metabolic acidosis can lead to numerous health issues, and it can even be life threatening.
Symptoms of alkalosis can include any of the following:Confusion (can progress to stupor or coma)Hand tremor.Lightheadedness.Muscle twitching.Nausea, vomiting.Numbness or tingling in the face, hands, or feet.Prolonged muscle spasms (tetany)
Acidosis is a condition in which there is too much acid in the body fluids. It is the opposite of alkalosis (a condition in which there is too much base in the body fluids).
Metabolic alkalosis occurs when digestive issues disrupt the blood's acid-base balance. It can also be due to conditions affecting the liver, kidneys or heart. Metabolic alkalosis is usually not life-threatening. It does not have lingering effects on your health once it is treated.
Metabolic alkalosis is a condition that occurs when your blood becomes overly alkaline. Alkaline is the opposite of acidic. Our bodies function best when the acidic-alkaline balance of our blood is just slightly tilted toward the alkaline.
Definition. Metabolic acidosis is a condition in which there is too much acid in the body fluids.
