Simple technique to verify CO(2) diffusion with the CarbonAid™ device

Heart Surg Forum. 2012 Aug;15(4):E212-4. doi: 10.1532/HSF98.20121015.


It has become common practice in cardiac surgery to flood the operative field with CO(2) to facilitate deairing of the heart. However, CO(2) delivery is variable and verification of CO(2) delivery can be challenging. We report a simple, reliable method to confirm CO(2) delivery. This technique ensures that the benefits of CO(2) delivery are provided to the patient during the operation.
