The heart monitors began to beep. Machines were sounding, alarms indicating erratic heart rhythms.

The doctor began to listen to his heart.

"Sat's are down to 80" a nurse yelled out.

"We're going to scan him for a pulmonary embolism. Bolus 5000 heparin. Start a drip at 1000 an hour" the doctor ordered.

Looking at the scan, the doctor sees it.

"Right pulmonary artery. Get angiography down here for a filter."

The machines began to sound again.

"BP's down to 60, pulse ox 72" a nurse calls out.

"No carotid pulse."

"Dammit, he's thrown another clot. Start chest compressions."
