Doctor's Notes on Bleeding
Bleeding may be caused by any number of injuries such as cuts, lacerations, or puncture wounds from sharp objects. Minor bleeding is very common, easy to treat, and usually has no long-term consequence. Extensive bleeding can be very dangerous. It may cause a drop in blood pressure and decreased organ blood flow, which could lead to shock. For any bleeding that is difficult to control with pressure or requires a tourniquet, call 911 immediately. If a person is bleeding, always check for other injuries such as a significant head injury, fractures, or dislocations.
Symptoms that may result from bleeding include pale, cool, clammy skin; fast heart rate, low blood pressure, lightheadedness, unconsciousness, and in very severe cases, death within seconds to minutes.
