My father experienced sudden shortness of breath while doing his usual routine in the farm. he has no chest pain and his blood pressure is 120/60. what should i do?

Get checked out: Sudden shortness of breath is not normal and can come from several different things without chest pain. He should get it checked out as soon as possible.

He needs cardiac w.u: He needs cardiac w.U, to start with exam and ekg and needs to be ruled out for valvular issues with echo and possibly stress test.

SOB: Get to er get ekg with rhythm strip and cardiac enzymes drawn along with chest x-ray to rule out pulmonary embolism.
