The new ward I am working at has a lot of monitoring.. So there are different alarm bells.
A long tone if the cables disconnect (e.g. the patient left the bed to go to the toilet equals 95% of the alarms..) a faster two tone alarm if something is wrong with the ECG and a really fast two tone alarm for a flatline.

No lie: Something there is always ringing. I'm pretty amazed that I am still able to listen to music in my spare freetime because it's like the audio-overkill.
So a couple of one tone and slow two tone alarms were ringing and it sounded like this song I heard on my way to work:



I did two or three dancing steps down the hallway and entered a room to see if the patient was alright.
