Optimal pacing strategies for coming off CPB
نویسنده
چکیده
Optimal pacing strategies employed after CPB enhance ventricular function with improvements in cardiac output and tissue perfusion. Pacing is optimized for each patient by taking into consideration the underlying electrophysiological abnormalities, as well as co-existing structural cardiac diseases. The primary objective of rhythm stability and improved cardiac function in the post-CPB period is obtained by 1. Optimizing pacemaker lead configuration and positioning as well as capture and sensing properties 2. Appropriate programming of pacemaker timing and intervals and use of correct pacing modes a. Adjusting pacing rate to obtain balance between cardiac output and myocardial oxygen demand b. Maintaining optimal atrio-ventricular (AV) synchrony and AV conduction delay c. Maximizing ventricular ejection through coordinated ventricular activation

Effect of cardiopulmonary bypass on vancomycin and netilmicin disposition.
The effect of cardiopulmonary bypass (CPB) on the disposition of vancomycin (15 mg/kg) and of netilmicin (3 mg/kg) was studied in 10 adults. The concentration-time profile of the drug in serum and renal clearance were characterized pre-CPB, during CPB, and post-CPB. Vancomycin and netilmicin exhibited initial decreases in mean concentrations in serum of 4.0 mg/liter (16.8%) and 2.2 mg/liter (29...

متن کاملOptimization of Pacing Strategies for Cycling Time Trials Using a Smooth 6-Parameter Endurance Model
Abstract. Computing the optimal pacing strategy for cycling time trials can be formulated as an optimal control problem, where a mechanical model and a physiological endurance model form the dynamical system and time to complete the track is to be minimized. We review approaches that use the 3-parameter critical power model to compute optimal pacing strategies and modify it to become a smooth 6...
