Well the easiest answer I can think of is to use the ideal gas equation and look at the terms and their effect on pressure. PV=nRT == P=(nrRT)/V, as can been seen from the equation: Pressure is directly proportional to Temperature and inversly proportional to Volume. So you trap air inside a fixed volume container. (Note: not every container will work. The walls of the container must be able to withstand the imbalance between the new inner air pressure and the atmospheric pressure.) Then simple cool the container. If you have gauge fixed to the rigid container (measuring the interior) you will see a drop in air pressure inside the container.
Less than 30CMH2o
cardiac cycle Normal is less than 120 (mmHg)
less than 120 over 80
Compression
No. Although pressure inside a tornado is lower than normal, it is still closer to normal pressure than it is to a vaccum. In most cases the pressure drop in a tornado is less than 10%.
Normal blood pressure should be less than 120/85mmHg.
Abnormally low Blood Pressure is called "Hypotension"(Hypo-= Below, beneath, under, less than normal, deficient, in the lowest state of; Tension= to strain or stretch.)Blood pressure is the force(strain) on the blood vessels' walls. Thus, Hypotension is the less than normal strain on the walls of the blood vessels.
I can say that it should be less than 150
An alcoholic should have the same blood pressure as anyone else, less than 120/80, if they are an adult.
Low pressure can refer to an actual air pressure mass that is less than the normal pressure. It can also refer to the amount of force you place on something or the force of water from a faucet.
Yes, it can make you pass out. Or it can also cause you to go into shock, which can be dangerous particularly if your normal blood pressure tends to run lower than the average normal blood pressure.
hypo means less than normal, or deficient, so hypo-volition would mean a less than normal, or deficient ability, to make a conscious choice or decision
