Vicki,

Are you simply wanting a method to notify staff that you need something done? If so, try one of the free messenger programs such as Yahoo Messenger, Google's, or Windows Messenger. Download it on each computer and set up user names for all the staff. You can then send an instant message to whomever you need (remain HIPPA conscious and do not use full names or critical info) and the message will light up on their toolbar alerting them to your needs. For example, before I leave the room I might message the MA that I need an EKG here (each room has me as a different user so they know where I am) and, by the time I exit the room the EKG machine and MA are there waiting.
Works great for me.
