What is the expected oxygen (O2) level in a patient with DKA?

In diabetic ketoacidosis (DKA), the metabolic derangement leads to a significant increase in the production of ketone bodies due to insulin deficiency and the breakdown of fat for energy. While DKA primarily affects glucose and acid-base balance, the respiratory compensation through hyperventilation can impact oxygen levels in the blood.

In cases of DKA, patients often exhibit tachypnea (rapid breathing) as a compensatory mechanism to eliminate carbon dioxide and correct metabolic acidosis. This condition can create a situation where oxygen levels may become elevated, especially if the patient receives supplemental oxygen or if their increased respiratory rate effectively improves ventilation-perfusion matching in the lungs.

In a typical case of DKA without significant pulmonary pathology, the oxygen saturation is often normal, but due to the body's compensatory mechanisms and potential for increased oxygen uptake during hyperventilation, a trend toward higher oxygen levels may be observed.

However, it's also important to acknowledge that many patients with DKA might present with an array of clinical features, including varying degrees of respiratory distress, but in a standard evaluation, those not experiencing complications or severe pulmonary issues could exhibit higher oxygen levels, especially following treatment maneuvers.

Thus, in this context, the expected outcome in a patient with D
