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%.
The braking distance is a function of several variables. First, the slope (grade) of the roadway will affect the braking distance. If you are going uphill, gravity assists you in your attempts to stop and reduces the braking distance. Similarly, gravity works against you when you are descending and will increase your braking distance.
