Slagæðasúrefnisinnihald
Slagæðasúrefni refers to the measurement of oxygen levels within the arterial blood. This measurement is a crucial indicator of how effectively the lungs are transferring oxygen from the air into the bloodstream and how well the circulatory system is delivering it to the body's tissues. Arterial blood is chosen because it represents oxygenated blood that has been pumped by the heart to the rest of the body. Low levels of slagæðasúrefni can signify a problem with lung function, such as in conditions like pneumonia or chronic obstructive pulmonary disease (COPD), or issues with the heart's ability to pump blood effectively. Conversely, abnormally high levels are less common but can indicate hyperventilation or receiving too much supplemental oxygen.
The most common method for assessing slagæðasúrefni is through arterial blood gas (ABG) testing, which involves
