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%.
mass is the amount of matter in an object weight is a measure of the gravitational force exerted on an object gravity is a force of attraction between objects that is due to their masses, which decreases as the distance between the objects increases.ravity is the attraction between two or more masses. so any object always has mass. if the object is near something like a planet gravity effects it. which gives a fore on it, called weight.
