Acute hemodynamic effects of controlled oxygen therapy in decompensated chronic obstructive pulmonary disease.

abstract：BACKGROUND:Hemorrhage in trauma is a significant challenge, accounting for 30% to 40% of all fatalities, second only to central nervous system injury as a cause of death. However, hemorrhagic death is the leading preventable cause of mortality in combat casualties and typically occurs within 6 to 24 hrs of injury. In c...
