In suspected acute myocardial infarction, which medication should be administered immediately if hypoxia is present?

When hypoxia is present in suspected acute myocardial infarction, giving supplemental oxygen right away is the priority. Oxygen increases the amount of oxygen carried in the blood, helping more oxygen reach the ischemic heart muscle and reducing further injury. The goal is to correct the low oxygen level and support myocardial oxygen delivery while other treatments are started. The other options don’t fix oxygenation directly or immediately. Heparin prevents clot progression but doesn’t rapidly correct low oxygen. Morphine can relieve pain but doesn’t address hypoxemia directly. Furosemide helps with fluid overload or pulmonary edema, not the immediate need to raise blood oxygen.
