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?
Fainting, also called syncope, is a loss of consciousness that is typically due to a lack of normal blood flow to the brain. Fainting is uncommon in dogs and not always caused by a lack of blood flow; there are other similar medical causes that result in fainting for both humans and animals. That said, no matter how scared dogs or cats may get, they never faint from fright the way a human might (e.g., from panic attacks, hyperventilating, etc.).
