Mechanical chest compressions as a last-ditch attempt to salvage a profoundly hypoxic but normotensive patient with a massive pulmonary embolism.

Massive pulmonary embolism is a common cause of morbidity and mortality. For patients presenting with massive pulmonary embolism, severe hypoxia is usually associated with severe hypotension. These patients should be considered for thrombectomy should thrombolysis and respiratory support fail to improve their condition. Should thrombectomy not be available or suitable, consideration should be given to offering mechanical chest compressions to 'break up the clot'. We describe a case in which this seemingly led to survival and full recovery.
