What is the purpose of measuring capillary refill time?

Measuring capillary refill time is primarily utilized to evaluate circulatory status. This assessment provides valuable information about the perfusion of blood throughout the body, which is critical for understanding how well the circulatory system is functioning. When blood flow to the capillaries is adequate, the refill time is typically quick; a prolonged capillary refill time can indicate poor blood circulation, shock, or other cardiovascular issues.

While assessing respiratory function, checking temperature regulation, and determining heart placement are important aspects of veterinary care, they do not directly correlate with the primary aim of capillary refill time measurement. Capillary refill time specifically focuses on how well blood is circulating to the extremities, highlighting its pivotal role in gauging overall circulatory health.
