At the intensive care unit you will be constantly exposed to frequent stimuli. Depending on the nature of your illness and how seriously ill you it may be necessary to administer medication that will help you to sleep
Occasionally it may be necessary for you to sleep all 24 hours of the day. The depth of sleep necessary in order to achieve peace and quiet varies. The depth of the sleep you have had affects what you subsequently remember following your stay at the intensive care unit. It can also affect how you feel following discharge from hospital.
The staff's task is to achieve an acceptable level of well-being for you with optimal sedation, as well as to reduce pain, anxiety and worry. It is also to allow you to be able to communicate with your surroundings in spite of receiving sedative medication. In connection with convalescence and as required the supply of sleeping pills will be reduced.
It is normal for one’s sleep rhythm to be disturbed during a period of stay at hospital. The surroundings in the room are important in order to create conditions conducive to peace and quiet. There should be the facility to vary the lighting between day and night. Noise from the surroundings, appliances and the tone of conversations should be adjusted to minimize distractions. An effort should be made to maintain good contact with staff, who will regularly inform you what is happening and give you information about the time, place and why you are hospitalized.
