Abstract
The shortfall between breath-hold time on cold-water immersion and the time required to make an underwater escape from a helicopter provides the rationale for emergency underwater breathing systems (EUBS) for passengers flying over cold water. This study compared three types of EUBS: a compressed ga...

Both trials resulted in significant 13-33% increases in total leukocytes, mostly driven by a 24-30% increase in neutrophils. A significant relationship was found between the change in core temperature (T(re)) during exercise and the increase in total leukocytes (r = 0.561). Similarly, the change in...
