In which populations is capillary blood gas testing most commonly preformed, and on what part of the body is this procedure usually done?Pediatric Patients Heel
Why is capillary blood not as desirable as arterial blood for testing blood gases?Because it is a mixture of blood from the capillaries, venules, and arterioles and is mixed with tissue fluid
