When a family member comes home from the intensive care unit, there is huge relief. Then the reality of recovery begins. Many people who have been in ICU, whether for pneumonia, sepsis, COVID, surgery or a heart or lung problem, come home much weaker than anyone expected. They may struggle to stand, get breathless walking to the bathroom, sleep poorly and feel low or anxious. This is common, and it does not mean something has gone wrong. It means the body and mind need time and support.
This guide explains what to expect and how a gradual, physiotherapy-guided routine can help in the first weeks at home.
Why people are so weak after ICU
Critical illness and long periods of lying still cause muscles to waste quickly. Strong medicines, sedation, breathing machines and poor nutrition add to this. Many patients also have stiff joints, poor balance and reduced lung capacity. Doctors sometimes call this group of problems "post-intensive care syndrome". It can include:
- Muscle weakness and tiredness, especially in the legs and shoulders
- Breathlessness with small efforts
- Poor balance and a higher risk of falls
- Difficulty concentrating or remembering things
- Poor sleep, low mood, anxiety or upsetting memories of the ICU stay
Families can be affected too. Caregivers often feel exhausted and worried, and that deserves attention as well.
The first days at home
The first priority is safety and routine. Follow the discharge instructions on medicines, oxygen if prescribed, diet and follow-up appointments. Set up the home so essentials are within reach, the path to the bathroom is clear and well lit, and a chair with armrests is available. If the bedroom is upstairs, it may be wiser to arrange a bed on the ground floor for the first weeks.
Breathing exercises
Do these sitting upright, 3 to 4 times a day:
- Relaxed breathing: 1 to 2 minutes of gentle, slow breathing with the shoulders relaxed.
- Deep breaths: 5 slow deep breaths with a 2 to 3 second hold, then rest. Repeat 3 times.
- Huffs: 1 to 2 huffs through an open mouth to bring up any mucus, followed by a cough if needed.
Simple strengthening exercises
Start with what the patient can manage today. Even small amounts done regularly add up.
- Ankle pumps: 15 times every hour while awake.
- Knee straightening in sitting: straighten one knee, hold for 3 seconds, lower. 8 to 10 each leg, twice a day.
- Arm raises: lift both arms forward to shoulder height and lower slowly, 8 to 10 times, twice a day.
- Sit-to-stand: from a firm chair, with hands on the armrests at first, 3 to 5 times, twice a day. Build up slowly.
- Standing balance: stand holding a firm support, with someone nearby, for 30 seconds. Repeat 3 times.
Walking
Begin with short walks inside the house, perhaps to the next room and back, two or three times a day, with a helper close by. Add a little distance every couple of days. A walking stick or frame may be needed for a while; a physiotherapist can advise on the right aid and height. You should be able to talk in short sentences while walking. If the patient uses a pulse oximeter, keep oxygen saturation within the range the doctor has advised.
Stop if there is chest pain, dizziness, a racing or irregular heartbeat, sudden breathlessness, or oxygen falling below the advised level. Sit down, rest, and contact the doctor if it does not settle.
A note on post-COVID breathlessness and fatigue
Some people recovering from COVID, including those who were never in ICU, have breathlessness and tiredness that lasts for weeks or months. For some, symptoms get worse a day or two after doing too much. If this happens, the approach is careful pacing: doing a little less than you think you can, resting before you become exhausted, and building up very slowly. Breathing retraining can help if the breathing pattern has become fast and shallow. Any new chest pain, palpitations or breathlessness should be checked by a doctor before increasing activity.
Sleep, mood and memory
Keep a regular day and night routine, with daylight and some activity during the day and a quiet, dark room at night. Write down important things, as memory may be patchy. Talking about the ICU experience can help, but if low mood, anxiety or nightmares persist, speak to your doctor, as specialist support may be needed.
Tips for caregivers
- Encourage independence: let the patient do what they safely can, even if it is slower.
- Keep a simple diary of walking distance, exercises and how they felt, to see progress over weeks.
- Share tasks among family members and take breaks yourself.
- Learn the warning signs below and keep emergency numbers handy.
Food and fluids for rebuilding strength
Muscles cannot rebuild without enough fuel. Many patients have a poor appetite after ICU, and some find swallowing harder for a while. Small, frequent meals often work better than three large ones. Include a source of protein at each meal, such as dal, paneer, curd, milk, eggs or pulses, unless the doctor has advised otherwise for kidney or other reasons. Follow any advice on fluids, salt or sugar from the treating team. If the patient coughs or chokes when eating or drinking, tell the doctor, as a swallowing assessment may be needed.
When to see a doctor urgently
- Breathlessness that is worse at rest, or blue or grey lips
- Chest pain, fainting, or a racing or irregular heartbeat
- Fever, new cough or a change in phlegm
- New confusion, severe drowsiness or sudden weakness of the face, arm or leg
- A painful, swollen calf or sudden sharp chest pain, which can signal a blood clot
- Not eating or drinking, or passing very little urine
