A new employee of your EMS system is about to take a protocol test in front of the EMS supervisor. As he is reviewing the protocol from memory, he gets confused about which amount of oxygen to administer to a patient with a suspected pulmonary embolism. How would you respond if he asks you for help?
A) "Administer 2 liters per minute by nasal cannula to all patients with suspected pulmonary embolism."
B) "Administer supplemental oxygen to the patient of sufficient amount to maintain the pulse oximeter reading at or greater than 94%."
C) "Since a pulmonary embolism is a vascular problem rather than lung problem, administer oxygen to maintain a pulse oximeter reading of greater than 95%."
D) "A patient with a pulmonary embolism has a perfusion deficit, not a ventilation deficit, so oxygen will not change things. Simply start ventilations and transport the patient."
B) "Administer supplemental oxygen to the patient of sufficient amount to maintain the pulse oximeter reading at or greater than 94%."
