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?
The medical term for fainting is syncope. Fainting is a sudden loss of consciousness, usually temporary and typically caused by a lack of oxygen in the brain. The brain oxygen deprivation has many possible causes, including hypotension (low blood pressure).his rise in the heart rate results in hypotension (drop in blood pressure) in other parts of the body, because the brain is flooded with blood (at the expense of other parts of the body). Hyperventilation combined with hypotension may result in short-term loss of consciousness, muscle weakening, and syncope (fainting).
