Keeping astronauts healthy as well as providing them with adequate medical care can be an enormous challenge due the extremely harsh environment of space. For years NASA has been conducting research and experiments to improve the medical care that astronauts can use in space. NASA teamed up with Impact Instrumentation Inc., a manufacturer and innovator of respiratory care products and instrumentation for military and civil emergency medicine, to develop better critical care capabilities. The Advanced Group Project of NASA worked with Impact Instrumentation to create the LTM (Lightweight Trauma Module). This single device combines once separate devices such as ventilators, heart monitors and IV pumps.
