Multi-organ support in intensive care
A plain-English guide for families explaining how intensive care machines and medicines temporarily take over for the lungs, heart, kidneys and other organs while a very ill person is given time to recover.

In short
- Organ support uses machines and medicines to do the work of struggling organs — lungs, heart, kidneys and others — while the body is given time to recover.
- It supports the body and buys time; it does not cure the underlying illness by itself, and recovery is often slow.
- Day by day the team will explain whether organs are improving, holding steady, or not responding — this picture can change in either direction.
- Reducing or stopping support when someone is improving is good news, not 'giving up'; difficult decisions are always discussed with you.
A plain-English summary. The detail — including risks and recovery — is below.

What is multi-organ support in intensive care?
When someone is very ill, more than one of their organs can start to struggle at the same time. The lungs, heart, kidneys, liver, blood or brain may all need help. Multi-organ support is the name for the machines, drips and medicines an intensive care (critical care) team uses to do the work of those organs for a while, so the body has time to rest and heal.
Organ support does not cure the illness on its own. It buys time and keeps the body going while doctors treat the cause — for example an infection, an injury or a problem with the heart. Support can include a breathing machine (ventilator), drugs to hold the blood pressure up, a kidney machine (dialysis or filtration), and feeding through a tube or vein.
Needing support for several organs means someone is seriously unwell, and it is right to be worried. It does not automatically mean they will not get better. Some people improve steadily; for others, recovery is slower, uncertain, or sadly not possible. The team will keep you updated honestly as things change.
This is intensive, around-the-clock care given by the NHS. It usually starts as an emergency, so there is rarely any choice of hospital or any private booking involved.
Types, options & approaches
There may be different ways to do this. The right approach depends on the clinical question and your circumstances.
Options at a glance
These are the main approaches described in this guide. The right option depends on the diagnosis, your goals and what your clinician thinks is safe.
Breathing (lung) support
Extra oxygen, a tight mask (non-invasive ventilation), or a tube into the windpipe attached to a ventilator that breathes for the person while they are sedated.
Heart and blood-pressure support
Drugs given through a drip to keep the blood pressure up and help the heart pump, so that blood and oxygen still reach the organs.
Kidney support
A filtering machine (dialysis or continuous filtration) that cleans the blood and removes extra fluid when the kidneys have stopped working properly.
Feeding and fluids
Nutrition given through a tube into the stomach or, if needed, into a vein, plus carefully controlled fluids, because a very ill body still needs energy to heal.
Preparing for your treatment
- Organ support usually starts as an emergency, so there is rarely time to prepare — the team acts first and explains as soon as they can.
- Ask the nurse or doctor to talk you through the machines and what each one is doing; no question is too small.
- Choose one family member to be the main contact, who can pass news on to everyone else and reduce repeated phone calls.
- Tell the team about the person's usual health, medicines, allergies and any wishes they have expressed, such as an advance care plan.
- Look after yourself too — eat, rest and take breaks; staff understand you cannot be at the bedside every moment.
- Ask whether the unit has a relatives' room, a follow-up clinic, or a charity such as ICUsteps that supports families.
- Keep a notebook or diary of what you are told, as it is a lot to take in and the picture can change.
What happens
On the unit, the person is cared for very closely, often one-to-one with a nurse. Tubes, wires and screens around the bed can look frightening at first; each one is helping or measuring something, and staff are happy to explain.
Medicines keep the person comfortable and usually drowsy or asleep, so they are not distressed by the tubes. A breathing machine may be doing their breathing. Drips give fluids, nutrition, antibiotics and drugs to support the heart and blood pressure. A kidney machine may be filtering the blood at the bedside.
The team reviews everything many times a day, adjusting support up when an organ struggles and down when it improves. Several specialists — intensive care doctors, nurses, physiotherapists, pharmacists and others — work together. You will usually be able to sit with the person, hold their hand and talk to them; familiar voices can be a comfort even if they do not seem to respond.
Is this treatment right for me?
A good consultation should explore whether it's the right choice for you now — including reasons to wait or consider something else.
May not be suitable if…
- Where the underlying illness or injury is so severe that organ support cannot lead to recovery, comfort-focused care may be kinder.
- If a person has clearly stated, for example in an advance decision, that they would not want invasive life support.
- When the burdens of intensive treatment would outweigh any realistic benefit, the team will discuss this openly.
- Decisions about who is likely to benefit are made by senior clinicians with the family, not by any fixed rule.
Delay or rearrange if…
- Organ support is started without delay in an emergency, so it is not usually something that is postponed.
- Where there is time, the team weighs up the likely benefit and the person's own wishes before escalating treatment.
- If the situation is unclear, a 'trial' of support for a set period may be agreed, then reviewed honestly.
- Families should never feel rushed into decisions; ask for time and clear information.
Alternatives to discuss
- Treating the cause without full intensive care, where the illness is less severe.
- Care on a high-dependency unit if only close monitoring or single-organ support is needed.
- Comfort-focused (palliative) care, when intensive treatment can no longer help.
- A time-limited trial of organ support, with an agreed point to review whether it is working.
Before you decide
Use this as a shared-decision checklist. The aim is not just “can this be done?”, but whether it is right for you, now, with the risks and alternatives clearly understood.
What matters most to me?
Think about symptoms, daily life, work, caring responsibilities, sport, fertility, travel, appearance and anxiety — the right choice depends on your priorities, not just the medical facts.
What are all my options?
Ask about waiting, monitoring, medicines, rehabilitation, a smaller or larger procedure, a different test, NHS referral, or a second opinion where that would help.
What would make me pause?
Active infection, pregnancy, unstable medical problems, smoking, medicines that increase bleeding, poor support at home, or feeling pressured are all reasons to slow down and get tailored advice.
What happens if I do nothing today?
For some problems, waiting is safe; for others, delay can make treatment harder. A good consultation should explain the trade-off in plain English.
Comfort, sedation or contrast choices
If local anaesthetic, sedation, contrast or pain relief is used, ask what is planned, why, and what it means afterwards.
Benefits
- Keeps oxygen and blood flowing to vital organs while the body is too ill to do this itself
- Buys time for treatments, such as antibiotics or surgery, to work on the underlying problem
- Allows organs that are struggling to rest and, in many people, recover
- Lets the team watch the person extremely closely and react within seconds if things change
- Keeps the person comfortable, settled and free of pain while they are most unwell
- Provides a setting where difficult decisions can be made carefully, with the family involved
Risks & complications
- Muscle weakness and weight loss from being very ill and still for a long time
- Confusion or vivid, frightening dreams (delirium), which is very common in intensive care
- Disturbed sleep, and losing track of day and night
- Discomfort or distress from tubes, despite medicines to ease this
- Infections picked up in hospital, including chest or bloodstream infections from lines and tubes
- Pressure sores from lying still, despite careful nursing
- Blood clots in the legs or lungs
- One organ recovering while another stays weak, lengthening the stay
- Lasting damage to an organ that does not fully recover, such as kidneys needing long-term dialysis
- Serious complications from the illness itself that the body cannot overcome
- Death, despite full support, when the underlying illness or injury is too severe
The biggest uncertainty is not the machines themselves but whether the underlying illness or injury will get better. Two people on similar support can have very different outcomes. Ask the team each day what they are most worried about, which organs are improving, and what would tell them treatment is or is not working.
Published figures to discuss
Survival and recovery after multi-organ support vary enormously depending on the illness, the person's health beforehand, their age, and how many organs are affected. There is no single, reliable percentage that fits every patient, so the team will give you a view tailored to your relative rather than a fixed figure.
| Figure | Reported range | How to interpret it | Source / confidence |
|---|---|---|---|
| Mortality as the number of failing organs increases | Rises steeply from single-organ to multi-organ failure | Risk is driven by the underlying disease, age, frailty and response in the first days, not by machines alone. | NHS — Intensive carenhs.ukSource-linked context |
| ICU-acquired weakness | Common after prolonged ventilation, sepsis or multi-organ failure; often quoted around 25 to 50% in high-risk survivors | Early mobilisation, nutrition and sedation minimisation help, but recovery can take months. | NHS — Intensive carenhs.ukPublished figure |
| Acute kidney injury needing renal replacement therapy | Common in severe shock, sepsis and multi-organ failure | Dialysis support may be temporary, but some survivors have persistent kidney impairment. | NHS — Intensive carenhs.ukSource-linked context |
| Treatment burden without meaningful recovery | A key risk in irreversible disease or severe frailty | Daily goals-of-care review is part of good ICU practice. | NHS — Intensive carenhs.ukSource-linked context |
These are literature figures, not a personalised prediction. Your own risks and likely benefits depend on your circumstances, your health, and how your care is carried out and followed up.
What happens afterwards
Recovery from critical illness is usually slow and uneven, and a large part of it happens after the person leaves intensive care — sometimes over many months. Getting off support is a gradual, step-by-step process, not a single moment.
- Feeling exhausted by small efforts, such as sitting up or washing
- Weak, wasted muscles that take weeks or months to rebuild
- Patchy or muddled memories of the time in intensive care, or no memory at all
- Low mood, anxiety, poor sleep or distressing dreams afterwards
- Poor appetite and weight that takes time to return
Aftercare
- Expect a slow, gradual recovery and pace activity rather than rushing back to normal.
- Follow any physiotherapy and rehabilitation plan to rebuild strength safely.
- Eat well and accept help with meals; appetite often takes time to return.
- Talk about frightening memories or dreams — these are common after intensive care and can be helped.
- Keep follow-up appointments and ask about a critical care follow-up clinic if the unit runs one.
- Let the GP know about the intensive care stay so ongoing problems are picked up.
- Look after carers too — supporting someone after critical illness is tiring and emotional.
- Name and direct contact for the unit or follow-up clinic
- A written summary of what happened and what support was given
- Details of any rehabilitation or physiotherapy plan
- A list of medicines on discharge and who reviews them
- Information on emotional support, such as ICUsteps, for patient and family
- Clear advice on warning signs and who to call
- A nominated family member to coordinate updates and appointments
⚠ Get urgent help if…
- Any sudden change you notice at the bedside — tell the nurse straight away rather than waiting
- After going home: a high temperature, shivering or feeling generally very unwell (possible infection)
- Increasing breathlessness, chest pain or coughing up blood
- A swollen, hot or painful calf, which can signal a clot
- Confusion, drowsiness or being hard to wake
- Not passing urine, or much less than usual
- Distressing flashbacks, nightmares or thoughts of self-harm — ask for help early
Who to contact: your clinician, clinic or test provider first (keep their number to hand). For urgent advice when you can't reach them, call NHS 111. In an emergency, call 999.
General guidance — it doesn't replace the specific advice your specialist gives you.
Results & realistic expectations
A good outcome means the supported organs recover enough for the machines and drugs to be withdrawn, and the person gradually wakes, breathes and lives without them. This becomes clearer over days to weeks rather than hours. Even after a good recovery, people are often weak and tired for a long time, and full recovery can take many months.
Organ support cannot guarantee survival or a return to exactly how someone was before. For some people the illness is too severe to overcome despite everything. The team will be honest with you about what they expect and will involve you in decisions.
How well someone does in the long run depends mostly on the illness or injury that brought them in, their health beforehand, and how their organs recover. Many people regain a good quality of life, though it can take a year or more. Some are left with lasting effects, such as reduced lung or kidney function, muscle weakness, or memory and mood problems, and may need ongoing care.
Related tests, treatments or support
Organ support is, by nature, several treatments used together — breathing, heart, kidney and feeding support are often combined and adjusted as a whole. Other treatments, such as scans, operations or specialist input, are added depending on the cause of the illness.
Follow-up & long-term care
Many intensive care units offer a follow-up clinic or rehabilitation service some weeks after discharge, to check on physical, emotional and memory problems and arrange further help. The hospital and GP should share information so that any lasting effects are picked up and supported.
- Ongoing physiotherapy and gentle exercise to rebuild strength
- Review of any medicines started in hospital
- Monitoring of organs that were affected, such as kidney function checks
- Emotional and psychological support for patient and family if needed
- Follow-up with the relevant specialist for the original illness
Repeat, follow-on and what comes next
- Support is constantly adjusted — increased if an organ worsens, reduced as it recovers; this is normal, not a setback.
- Some people need support restarted after it is reduced, for example going back on the ventilator; this happens and is not a failure.
- A 'trial' of support may be agreed for a set time, then reviewed honestly with the family.
- Where treatment is no longer helping, the focus may rightly shift to comfort and dignity, always discussed with you.
Ask what happens if the result is unclear or needs repeating, and what is included if further tests or follow-up are needed.
What good aftercare looks like
- A named contact on the unit and honest, regular updates for the family.
- Clear, plain-English explanations of each machine, drug and decision.
- A critical care follow-up clinic or rehabilitation plan after discharge.
- Emotional and psychological support for both patient and family, including signposting to ICUsteps.
- Good handover to the ward, GP and any specialists so lasting effects are not missed.
What affects the cost
Costs vary a great deal between people and providers, and we don't publish prices. What matters is understanding what drives the cost and making sure your quote is complete. The main things that affect it:
- Intensive care is almost always provided as urgent NHS care, so families do not usually face a private bill.
- Where any private critical care exists, cost depends on the length of stay, which can be days to many weeks.
- The number of organs being supported and the machines and medicines used affect the intensity of care.
- One-to-one specialist nursing and round-the-clock consultant cover are major parts of the cost of critical care.
- Tests, scans, operations and specialist opinions add to the overall care.
- Rehabilitation and follow-up after intensive care are part of the wider picture of recovery.
- Confirmation of whether care is NHS or private, and who is responsible for any costs
- Who the consultant in charge of intensive care is
- How decisions about treatment will be shared with the family
- What happens if more organ support, surgery or transfer is needed
- Whether a follow-up clinic or rehabilitation is included
- How the family will receive updates and who to contact
On the NHS? Multi-organ support is intensive, around-the-clock care that is almost always provided by the NHS, usually as an emergency, rather than as a private self-pay treatment.

Consent traps and marketing red flags
These are not small details. They are often where patients lose choice, time to reflect, or realistic expectations.
Consent traps
- Families not having the machines and their purpose explained in plain language.
- No honest discussion of what the team expects, including the possibility that the person may not recover.
- Treating reduction of support as 'giving up' rather than a normal part of getting better.
- Not asking about, or recording, the person's own previously expressed wishes.
- Big decisions being made without the family being given time and clear information.
Marketing red flags
- Any claim that life support 'guarantees' recovery or survival.
- Private services implying they can offer outcomes the NHS cannot in an emergency.
- Pressure to transfer a critically ill person for non-clinical reasons.
- Language that hides how serious the situation is, or how slow recovery can be.
Choosing a specialist safely
- Check the specialist is on the GMC Specialist Register for this area.
- Make sure they work at a CQC-registered service, and look for membership of the relevant Royal College or professional body.
- You're entitled to time to consider and to have your questions answered before you agree — the specialist who looks after you should explain it, not a salesperson.
- Be wary of pressure: time-limited offers or deposits taken before you've had time to think are red flags, not bargains.
- You're entitled to your total cost in writing — including any follow-up — before you decide.
Questions to ask your medical professional
Take this to your consultation. A good specialist will welcome every one of these.
- Which of my relative's organs are being supported, and how?
- What is the main illness or injury you are treating, and how is it responding?
- Which organs are improving, and which are you most worried about?
- What would tell you the treatment is working — or that it is not?
- How will you keep them comfortable and free of pain?
- Is there a follow-up clinic or support service for when they recover?
- Are you on the GMC Specialist Register for this area, and which Royal College or professional body are you a member of?
- Will you be the specialist who carries out my treatment, and who looks after me afterwards?
- What are the risks for someone like me, and how often do your own patients have a problem or need it repeated or redone?
- What does a realistic result look like — and what can this treatment not achieve?
- What are my options, including waiting, doing nothing for now, or choosing a different approach?
- Can I have written information, results and aftercare instructions in a format I can use, including any accessibility or communication support I need?
- What is the total cost in writing, including any follow-ups, and how much time do I have to decide?
