CSRO2 is measured using a pulse oximeter, which is a non-invasive device that clips onto a finger or earlobe. The pulse oximeter shines a light through the skin and measures the amount of light that is absorbed by hemoglobin. The amount of light that is absorbed is proportional to the oxygen saturation of hemoglobin.
CSRO2 is a critical parameter to monitor in patients with respiratory problems, such as pneumonia or asthma. It can also be used to monitor patients who are undergoing surgery or who are critically ill.
Normal CSRO2 levels are between 95% and 100%. CSRO2 levels below 90% are considered to be low and can indicate that a patient is not receiving enough oxygen. CSRO2 levels below 80% are considered to be critical and can lead to organ damage or death.
If a patient's CSRO2 levels are low, the doctor may order supplemental oxygen therapy. Supplemental oxygen can be given through a nasal cannula, a face mask, or a ventilator.
CSRO2 is a critical parameter to monitor in patients with respiratory problems. It can help to assess the oxygenation status of a patient and guide treatment decisions.
