Prolonged Use of Automated CPR Aids In Revival of Hypothermia Patient

It was the middle of winter in Michigan and a 56-year-old male was found down in the snow, cold and unresponsive. At EMS’s time of arrival, he had a Glasgow Coma Scale (GSC) of 6, pinpoint pupils and was given NARCAN®, but was still unresponsive.

When he arrived at the hospital, the unresponsive patient had a GSC of 3 and CPR was initiated with the Michigan Instruments Life-Stat automated CPR device, along with intubation. He was experiencing ventricular fibrillation, considered the most serious cardiac rhythm disturbance. One attempt at defibrillation was made, but the temperature of the patient was 25 degrees Celsius, therefore, no further shocks were delivered.

The patient remained on the Life-Stat automated CPR Device, while an intravascular warming catheter was inserted into the femoral artery, and an esophageal warming device was administered. These warming devices were used in conjunction with the Life-Stat device for 3 hours and 45 minutes. During that time, his temperature rose from 25 degrees to 30 degrees Celsius. Once his temperature rose, he was given another shock, but that was unsuccessful.

He was then given an epinephrine drip and additional shocks. Finally, he did open his eyes and moved his extremities. One hour later, he was able to follow commands while still on a ventilator.

The patient was then moved to ICU where had additional tests and imaging done. He showed no signs of edema on his head or chest, and while in ICU he was weaned of the drips, extubated and slowly improved. Nine days after his arrival in the ER, he was discharged.

When asked how often the automatic CPR device was used in the hospital, Dr. Miller responded with “We use it daily, for every cardiac arrest.”

This case is just one of many examples where a Michigan Instruments automated CPR device was used to administer continuous, consistent CPR to cardiac arrest patients in a prolonged resuscitation. Light enough to be incorporated into any hospital crash cart set up, perform precise, programmed, hands-free CPR and never get tired with our Life-Stat or Thumper CPR machines.
