Key result
The relationship between systolic blood pressure and pulse transit time in anesthetized dogs was nonlinear and logarithmic, with correlation coefficients often greater than 0.96.
The relationship between systolic blood pressure and pulse transit time is nonlinear and logarithmic, suggesting caution is necessary when using this relationship to monitor blood pressure due to variability in coefficients.

Nonlinear SBP-PTT relationship in dogs urges caution for monitoring applications; leaves open clinical translation and validation.
Tang et al. (2014) studied Blood pressure monitoring (n=3). Pulse transit time (PTT) vs. Invasive systolic blood pressure was evaluated on Relationship between systolic blood pressure and pulse transit time. The relationship between systolic blood pressure and pulse transit time in anesthetized dogs was nonlinear and logarithmic, with correlation coefficients often greater than 0.96.
