The deceleration time is another simple means of evaluating the MV area, in which decay of the mitral inflow profile through a stenotic MV is examined. The following formula describes the relationship of the deceleration time to the MV area (19):
This is a complicated thing. The high pressure side will measure in excess of 250 psi, but that's not important. When filling 134a, you only need to watch the low pressure side.When the compressor kicks on (which it will only do when the pressure is above 40 psi) the pressure will drop.If the lines are full enough, the pressure will remain around 40-45 psi while it's running.f this happens, (and only if you have 134a) you can release the excess pressure from the valve just like you would emptying a tire. Be sure you do this on the LOW side, and do it while the vehicle is running, so you can watch the pressure.
