Web13 dec. 2024 · Purpose of the test. The purpose of a blood gases test is to evaluate the amount of oxygen and carbon dioxide and the acid-base balance, or pH, in the blood. Blood gases testing is primarily used for diagnosis and monitoring of different medical conditions. Diagnosis is the process of finding the cause of a person’s health problems. WebCause is an increase in respiratory rate or volume (hyperventilation) or both. Respiratory alkalosis can be acute or chronic. The chronic form is asymptomatic, but the acute form causes light-headedness, confusion, paresthesias, cramps, and syncope. Signs include hyperpnea or tachypnea and carpopedal spasms. lassila \\u0026 tikanoja pasilaWebThe patient’s arterial Pco2 is lower than the normal value of 40 mm Hg because hypoxemia has stimulated peripheral chemoreceptors to increase his breathing rate; hyperventilation causes the patient to blow off extra CO2 and results in respiratory alkalosis. lassila tikanoja jätehuolto turku
