Hemodynamic monitoring with esCCO yields cardiac output values different from those measured by LiDCOrapid.
The 35 s rebreathing period yielded cardiac output measurements similar in accuracy to those with 50 s rebreathing.
An average of three measurements taken randomly during the respiratory cycle was considered and was referenced to body weight to yield the cardiac output (Q).
The resulting model generates physiological pressures in both systole and diastole, and yields realistic cardiac output and stroke volume at physiological Reynolds numbers.
Tachibana and coworkers [ 23] reported the use of a shorter duration of rebreathing (35 s versus 50 s), which mitigated these effects but yielded a cardiac output measurement that is similar in accuracy.
Protective ventilation yielded lower cardiac output (P < 0.05) and higher pulmonary vascular resistance (P < 0.001) after 2 h of mechanical ventilation and endotoxemia, despite similar baseline values (Table 1).
This catheter was inserted via a 4 F introducing sheath (Arrow, Reading, USA) and connected to a bedside computer (COLD Z-021, Pulsion Medical Systems, Munich, Germany. The COLD Z-021 is the precursor to the current transpulmonary thermodilution pulse contour cardiac output (PiCCO™) technique and yields the same cardiac parameters.
There were no age-dependent differences in mitochondrial pool, as quantified by Mitotracker red staining, quantification of citrate synthase (CS) activity and total cardiac mitochondrial yield.
Murine ESCs differentiating into the cardiac lineage yield several specialized cell types of the heart, such as atrial-, ventricular-, sinus nodal- and Purkinje-like cells.
This bioenergetic inefficiency cannot be attributed to reduced mitochondrial mass, which seems to remain preserverd in aging mouse cardiomyocytes as quantified by specific staining with Mitotracker red, total cardiac mitochondrial yield quantification and CS activity measurement.
