Key result
The transonic flowmeter system demonstrated a strong linear correlation with pump flow (r = 0.999, p < 0.001) for measuring cardiac output and regional blood flow in rats.
Population
Sprague-Dawley (SD) rats

Facilitates precise hemodynamic measurements in rat models; extends preclinical tools but leaves open clinical translation.
Effect estimate: r = 0.999
p-value: p=< 0.001
The transonic flowmeter system is an accurate and highly reproducible method for measuring cardiac output and regional blood flows in rat models.
Li et al. (1996) studied Sprague-Dawley (SD) rats. Transonic flowmeter system vs. Pump flow was evaluated on Correlation between meter and pump flow (r = 0.999, p=< 0.001). The transonic flowmeter system demonstrated a strong linear correlation with pump flow (r = 0.999, p < 0.001) for measuring cardiac output and regional blood flow in rats.
