We are a start-up focused on re-inventing CPR delivery in the catheterization ("cath") lab. We are focused on bringing to market a novel mechanical CPR device, designed specifically for use within the cath lab, which delivers patient-specific CPR compressions while the Interventional Cardiologist is able to continue performing lifesaving measures without angiographic hindrance.
The current guidelines for CPR, provided by the American Heart Association (AHA) and adhered to in Canada by the Heart and Stroke Foundation, is to deliver 100-120 compressions per a minute at a depth of between five and six centimeters. However, chest compressions performed in hospital did not meet the recommended frequency (100-120/min) in 30% of cases and required depth (5cm) in 40%. Additionally, weariness started after one minute of manual CPR with a continuous drop in quality during the first three minutes; with adequate compressions (depth and frequency) decreasing from 92% to 67% to 39% during the previously cited timeframe and lowering to 18% after five minutes.

In spite of the development of mechanical CPR devices, the AHA only advises their use in unfavorable situations, such as the catheterization lab, where it is very difficult to administer high-quality compressions given the proximity of the necessary imaging equipment. The current devices either use a piston positioned directly above the chest cavity or a load-distributing band, both of which greatly interfere with angiographic imaging and the ability of the healthcare professional to complete time-sensitive procedures with every minute being vital for recovery.
