Videothermometry infrared during respiratory arrest and cardiac ischemia periods. The figure represents two groups; (a) sham group during ventilatory arrest period M5 and (b) treated group during cardiac ischemia period M5. Observe the respective temperature bars and the heat variations in the myocardial tissue according to the colors. In (a) a green isotherm was used and the temperature between 36.9 °C and 39 °C is noted. In (b) a blue isotherm was used and the temperature ranges between 32 °C and 34.5 °C. Arrows 1 and 2, indicate the location of the heart, in the caudal vena cava and right atrium areas, a brown spot is evident, meaning a cooler region with the temperature approximately 32 °C. The treated group, demonstrated a considerable reduction in temperature, indicating a significant decrease when myocardial ischemia occurs. UEA / UENF, 2015
