Abstract

Cardioplegia is a mixture of blood and potassium/crystalloid solution administered to protect the myocardium during cardiopulmonary bypass (CPB) procedures. Microplegia is a termed used to describe cardioplegia that uses minimal (non-traditional) amounts of crystalloid to carry the potassium solution. I have designed a microplegia technique that utilizes a syringe driver but is more user-friendly and cost effective.

Claims

1. The delivery options are limited to 4 options. High K⁺, Low K⁺, Burst, and Blood Only. The labels may have a different name, but the function stays the same. The actual solution may vary by surgeon preference. The delivery rate of 20 meQ/L for induction and 10 meQ/L is a suggested rate but may alter on the final product depending on physician preference.

2. The display on the screen will show pertinent information, and may be customized to each institution.

3. The flow sensor communicates with the syringe driver to auto-start, auto-stop, and determine flow delivery rate based on the actual delivery rate in mL/minute.

4. The syringe driver display may be a touch screen or have buttons to depress.
