Diving mammals.
The ability of diving mammals to forage at depth on a breath hold of air is dependent on gas exchange, both in the lung and in peripheral tissues. Anatomical and physiological adaptations in the respiratory system, cardiovascular system, blood and peripheral tissues contribute to the remarkable breath-hold capacities of these animals. The end results of these adaptations include efficient venti...

a 35 year old diver comes to your office. he had hyperglycemia in his last check up. he asks if he can steel dive in spite of hyperglycemia. we reviewed the recent studies about diabetic persons who dive. recent studies have shown that well controlled diabetic persons may be permitted to dive, but if they have any problem such as diabetic nephropathy, retinopathy, neurological and cardiac probl...
متن کاملAdvanced Diving Physiology
The human's normal atmosphere, oxygen and nitrogen, produces both toxic and narcotic effects when breathed at high pressure. In addition, the inert gas is absorbed and must be eliminated from the body at a controlled rate to avoid serious complications. Carbon dioxide has significant implications at the higher pressures encountered while diving and may alter the human’s sensitivity to both oxyg...
متن کاملEnergy Dumpster Diving
Power data alone cannot identify sources of energy inefficiency. However, correlating power data with utilization statistics can reveal where power is used well and where it is wasted. We describe a sensing infrastructure, PowerNet, that monitors power and utilization in a building environment. The deployment includes both wired and wireless sensors and covers offices, networking closets, and s...
متن کاملAnimation of Human Diving
The motion of a human platform diver was simulated using a dynamic model and a control system. The dynamic model has 32 actuated degrees of freedom and dynamic parameters within the range of those reported in the literature for humans. The control system uses algorithms for balance, jumping, and twisting to initiate the dive, sequences of desired values for proportional{derivative servos to per...
