Comparison Between Actual And Predicted Sweat Rates In Burn Survivors Using A Predictive Model For Fluid Replacement, Timothy P. Schaefer, Elizabeth A. Gideon, Erin M. Harper, Zachary J. Mckenna, Rachel M. Cottle, Ollie Jay, Craig G. Crandall
International Journal of Exercise Science: Conference Proceedings
Sweating is a primary physiological response necessary to regulate body temperature in hot environments. Recent literature identifies a correlation between multiple variables (i.e., height and weight, environmental temperature, humidity, intensity and duration of exercise, and venue of exercise) and the rate of sweat loss during physical activity in healthy participants. These findings were then used to create a model to predict fluid loss via sweat, and thus the fluid replacement necessary to rehydrate during and following exercise (sweatratecalculator.com). Importantly, this calculator was modeled with data from uninjured, healthy individuals and therefore may not be accurate for burn survivors. Grafted skin …
