The primary goal is to correct any imbalance, restore the patient's health, and return the patient to normal activities as quickly as possible. To help prevent ICU psychosis, many critical care units are now:
using more liberal visiting policies,
providing periods for sleep,
protecting the patient from unnecessary excitement,
minimizing shift changes in the nursing staff caring for a patient, orienting the patient to the date and time,
reviewing all medical procedures with an explanation about what to expect,
asking the patient if there are any questions or concerns,
talking with the family to obtain information regarding religious and cultural beliefs, and
even coordinating the lighting with the normal day-night cycle, etc.
How long does ICU psychosis last?
ICU psychosis often vanishes magically with the coming of morning or the arrival of some sleep. However, it may last 24 hours or even up to two weeks with fluctuations of the level of consciousness and behavior patterns. Although it may linger through the day, agitation frequently is worst at night. (This phenomenon, called sundowning, is also common in nursing homes).
Fortunately, ICU psychosis usually resolves completely when the patient leaves the ICU.
How common is ICU psychosis?
Some estimate that one patient in every three who spends more than five days in an ICU experiences some form of psychotic reaction. As the number of intensive care units and the patient population in them grow, the number of individuals affected by this disorder will correspondingly increase. With patients being transferred out of the ICU more rapidly than in years past; ICU psychosis may be more common in other areas such as the regular medical floor of the hospital or sometimes may even occur after discharge from the hospital.

Panic attacks are sudden feelings of terror that strike without warning. These episodes can occur at any time, even during sleep. A person experiencing a panic attack may believe that he or she is having a heart attack or that death is imminent. The fear and terror that a person experiences during a panic attack are not in proportion to the true situation and may be unrelated to what is happening around them. Most people with panic attacks experience several of the following symptoms: racing heartbeat, faintness, dizzyness, numbness or tingling in the hands and fingers, chills, chest pains, difficulty breathing, and a feeling of loss or control. There are several treatments for panic attacks.

Vancomycin-resistant enterococci (VRE) infection is the most common type of infection acquired by patients while hospitalized. Patients at risk for VRE are those who are already ill, and hospitalized, including individuals with diabetes, elderly, ICU patients, kidney failure patients, or patients requiring catheters. Enterococci can survive for months in the digestive tract and female genital tract. Other risk factors for acquiring VRE include those how have been previously treated with vancomycin and combinations of other antibiotics. Treatment of VRE is generally with other antibiotics other than vancomycin. Prevention of VRE can be achieved by proper hand hygiene.

Biologic rhythms, or biorhythms, are how our bodies respond to the regular phases of the sun, moon, and seasons.
