Being a nursing student who is deaf in one ear and partially in the other ear -- I have a special interest in your situation.
As mentioned on other threads -- I use an electronic stethoscope to hear sounds.
Fortunately, I hear well enough to hold a normal conversation, and can hear IV alarms, and understand the STAT overhead pages.
Drawbacks...I cannot tell which direction the sound is comming from. Also, I had a hell of a hard time hearing in the OR when we did our "outside classroom experiences." The Surgeon asked me to answer his page -- and I had to step outside of the OR to understand the operator (phone). It's the background noise that kills me.
I plan on looking into amplified hearing aids/etc once I get out of nursing school
and get a real world job. Right now--just have ultra high deductible insurance (mainly for cancer/etc.) -- that won't even begin to look at hearing equipment/etc.
