Position the patient in High Fowler's position to reduce the work of breathing and administer supplemental oxygen to target an SpO2 of ≥92%.
A stable blood pressure does not rule out significant right ventricular strain. Closely monitor for signs of decompensation, including a sudden drop in SpO2, increased dyspnea, or hypotension. Avoid activities that could dislodge the clot or increase cardiac workload, such as ambulation or strenuous deep breathing exercises in the acute phase.
Do not delay oxygen therapy for pain medication. While analgesics are important, untreated hypoxemia can lead to rapid clinical deterioration and cardiac arrest.
