C. Meredith et J. Edworthy, ARE THERE TOO MANY ALARMS IN THE INTENSIVE-CARE UNIT - AN OVERVIEW OFTHE PROBLEMS, Journal of advanced nursing, 21(1), 1995, pp. 15-20
There are many reported problems with auditory warnings in critical ca
re areas of hospital such as the intensive care unit (ICU) and operati
ng room. There are too many alarms; many of them are unnecessarily lou
d and continuous, which can be irritating and annoying for staff. The
problem of excessive alarms is further complicated by the fact that th
ere are no standards agreed between manufacturers on the auditory warn
ings used for medical equipment. Therefore, the same piece of equipmen
t manufactured by different companies will have different alarms that
could result in confusion. Another possibility as to why confusion cou
ld occur is because alarms are often inappropriate in terms of their '
urgency mapping'. This means there is generally no relationship betwee
n the urgency of a medical situation and the perceived urgency of the
alarm that signals that condition. A further problem involves the numb
er of false alarms that occur; that is, alarms that are not signalling
a medical emergency. The following paper discusses these problems and
suggests attempts to remedy some of them. There is also a brief discu
ssion of the amount of monitoring that occurs on the ICU as the more m
onitors there are the greater the number of alarms there will be.
