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?
