In a cardiac patient with a history of heart attacks, if SpO2 is 94%, what level of oxygen should be given?

Oxygen is given when a patient is actually hypoxic or showing signs of breathing distress, not just because they have heart disease. A SpO2 of 94% means the blood is adequately oxygenated, and there's no current indication of hypoxia. In patients with cardiac history, withholding supplemental oxygen unless SpO2 drops below the target (often 94% or lower, depending on protocol) helps avoid potential downsides of oxygen overuse, such as unnecessary vasoconstriction and increased workload on the heart. So, with SpO2 at 94% and no distress described, the appropriate course is to provide no supplemental oxygen and continue to monitor the patient. If SpO2 falls below the threshold or symptoms of hypoxia appear (e.g., shortness of breath, chest pain with signs of poor perfusion), then oxygen should be started and titrated to maintain the target range.
