I would like to inquire if it is safe to run a treatment with teh venous chamber monitor remianed clamped during the eun. A line catheter was used and it was not registering venous resistance, so it triggers an alarm on and off, but when it was clamped it was okay. Any untoward consequences?

You should get some kind of reading. Check your venous monitoring for any defects. Never clamp a monitor line that measures either arterial or venous pressures. If there was any change in the pressures you would never know and by not knowing what is happening at the access damage could be occuring.

The venous monitor line should not be clamped for an extended period (other than troubleshooting). If you have no reading there, you take a chance of having the system clot off without warning. Usually (not always) the venous side is where you will see pressure changes that indicate clotting. In addition, I agree with the previous post that access damage could be occuring. To troubleshoot things like this, I would change transducer protectors and have even had a problem with the line itself being faulty. Our tubing has a medication port at the venous drip chamber that we can switch over to the monitor line if we suspect the line itself. If that doesn't cure it, it may be a machine malfunction.
