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%.
Yes but only just. Gravity is a relationship between the mass of a planet and the distance from the centre. In simplistic terms G = M /R Where G = gravity, M = mass and R = radius. It's a bit more complicated than that-but is a good approximation. For example Saturn is about 9 times larger than the Earth but the gravity is only just above that of the Earth.
