Objective: In Part II, you will be able to calculate the impact angle of blood spatter. Procedure: Using a protractor and a dropper, allow a single drop of blood to drop from three angles: 25Â°, 45Â°, and 75Â° onto a sheet of paper.5Â° 45Â° 75Â°. Determine the relationship between the angle of impact and the shape of the blood drop. (1 point). Using the equation sin c = width / length, calculate the angle for each trial (show your work in the space below).
UNEXPLAINED FAINTING Fainting is a common problem accounting for 1-3% of emergency department visits and 6% of hospital admissions in the U.S. each year. 1. Fainting: Occurs when blood pressure drops and limits oxygen to the brain; May also be called âpassing out,â âblackoutâ or âsyncopeâ Usually lasts only a few minutes, but may be followed by a period of confusion; Affects all age groups and sometimes occurs in healthy people; Can be a sign of an underlying medical condition; WHY MONITOR?
Syncope (medicine) Syncope, also known as fainting, is a loss of consciousness and muscle strength characterized by a fast onset, short duration, and spontaneous recovery. It is caused by a decrease in blood flow to the brain, usually from low blood pressure. There are sometimes symptoms before the loss of consciousness such as lightheadedness, sweating, pale skin, blurred vision, nausea, vomiting, or feeling warm. Syncope may also be associated with a short episode of muscle twitching. When consciousness and musc
