WebIn PH patients, the use of preload reserve (Frank-Starling's mechanism) helps preserve RV function. Furthermore, according to Laplace's law, an increase in afterload can be offset by an increase in RV wall thickness (RV hypertrophy), and this normalises RV wall stress and myocardial oxygen consumption. Webcardiac reserve (The difference between the maximum and resting cardiac output is called cardiac reserve. Preload is the amount of tension in the ventricular myocardium … WebFluid responsiveness is an increase of stroke volume of 10-15% after the patient receives 500 ml of crystalloid over 10-15 minutes (as defined by Paul Marik) Fluid responsiveness … brittany diehl
