Long-term oxygen therapy improves the survival of patients with chronic obstructive pulmonary disease. Measures proposed in clinical clinics to evaluate the indication and monitoring of arterial blood pressure therapy and arterial oxygen saturation. The use of pulse oximetry has been widespread, but the information to determine if these measures are interchangeable is insufficient. The objective is to review the physiological foundations of variables related to oxygenation and their forms of measurement. In the assessment of the patient with respiratory pathology, pulse saturation is a valuable clinical aid., however, its limitations do not allow, in certain ranges, to replace direct arterial blood pressure (arterial blood gas) measurement of arterial saturation and arterial oxygen pressure, to determine the indication of oxygen therapy.
