cardioplegia delivery pressure
The pressure at which cardioplegic solution is administered to achieve adequate myocardial distribution and protection.
Full Definition
Cardioplegia delivery pressure refers to the optimal pressure range (typically 150-300 mmHg) used to infuse cardioplegic solution into the coronary circulation. Proper delivery pressure ensures uniform distribution throughout the myocardium while avoiding tissue damage from excessive pressure. Factors influencing delivery pressure include the degree of coronary stenosis, aortic regurgitation, and the specific cardioplegia formulation being used. Anesthesiologists must monitor these pressures carefully as inadequate delivery can result in incomplete myocardial protection.
Usage
Usage note: Always specify pressure values and units when documenting.
