Pressure Drop From Kegel

Hey pumpers,

Just a quick question about pressure readings. I’ve been pumping for a long time now but haven’t been able to find an answer on this.

Whenever I go into the pump erect and pump to about 3”Hg (I do low pressure pumping) I then kegel and the pressure gauge drops back down to about 1.5”Hg or 2”Hg. I’ve always played it safe and just ignore the drop on the gauge but I’d like to know what other pumpers thoughts are. Did the pressure indeed drop and require more pumping to reach my desired level or what?

Thanks,

You have to trust your gauge. So if the pressure drops for whatever reason, you have to pump it back up to your target pressure.

I’ll have to go off the gauge then, thanks.

I think what is going on is based on a simple equation P1xV1=P2xV2. Which becomes P2=(P1xV1)/V2. I’m assuming that you are pumping with air.. Which is a compressible fluid. Thus think about it like this P1 is initial vac pressure, V1 is initial volume of air and blood in penis. You introduced more blood to the system by kegel, therefore V2 is greater than V1 so P2 should be less than P1 for the system.

Be aware this is a vac system, so you are adding positive pressure from within the system.

I think that’s how it works, and DO TRUST your gauge! Hope that helps a little bit!

Sorry, V2 decreases, thus P2 increases. Positive internal pressure makes the gauge pressure drop.

Had to draw the system on paper.oops!
