POCT in the ED â¢ Faster does not always lead to better outcome â¢ Lab tests are rarely the rate limiting factor in ED disposition â¢ Process analysis is the key understanding and improving patient throughput in the ED â¢ Test menu selection is a critical component of the potential application of POCT â¢ Match available tests to disposition decisions
Gravity decreases with altitude as one rises above the Earth's surface because greater altitude means greater distance from the Earth's centre. All other things being equal, an increase in altitude from sea level to 9,000 metres (30,000 ft) causes a weight decrease of about 0.29%.
Gravitational pull varies as the square of the distance from Earth (specifically its center). So, we are 4,000 miles from it, and if you set gravity = 1 here (arbitrary number), then at 4000 miles distance (or, a doubling of distance from the center), gravity is 0.25 that at the surface.
