Hospital alarms

Some patients are connected to monitors that sound dozens of alarms for problems from a low heart rate to clogged intravenous medication tubing. Patients and families also can press various emergency alarms. Nurses must respond to these alarms quickly, and keep from being desensitized to them. More serious alarms generally sound faster and at higher pitch, signaling nurses that the problem could be urgent.
