Oxygen Therapy
Maintaining oxygen saturation is one of the primary goals in maintaining blood oxygenation. If
there is any question concerning a patient’s blood oxygenation, supplemental oxygen should
be provided until assessment of arterial blood gases or hemoglobin saturation confirms that
oxygen supplementation is not necessary. When this equipment is not available, assessment
will have to be based on clinical dyspnea or auscultable abnormalities and clinical signs of
hypoxia (cyanosis of the mucous membranes or dark colored blood, tachypnea, tachycardia,
and anxiety). Individually, the clinical signs do not prove hypoxemia, but together they are
suggestive of hypoxemia. There are a variety of methods of oxygen therapy. The method
selected depends on the expected duration of therapy, the demeanor of the patient, and
equipment availability. Available methods include face mask, oxygen bag (hood), oxygen
cage, transtracheal, and nasal insufflation. The ultimate goal of oxygen therapy is to provide
adequate oxygen to the blood, using the lowest possible inspired oxygen concentrations.
