The Winchester Critical Care Unit is a specialised area in the hospital. It includes Intensive Care (ICU) and High Dependency (HDU) areas.
Critical Care is for patients who are critically unwell and need additional support that cannot be provided in a normal ward setting.
During critical illness, vital parts of the body (organs) may stop working. We are able to support one or more of a patient's vital organs, such as their lungs, heart or kidneys.
Patients who are not critically unwell may be admitted to Critical Care if they require very close monitoring, such as after major surgery.
In Critical Care, patients are closely monitored and treated by a team of specially trained healthcare professionals.

We understand this can be a worrying time. If you have questions, please ask the Critical Care staff. You will also have opportunities to receive updates from the medical team.
Sometimes a patient's condition may change quickly. We will try to update you as soon as possible. Please make sure we have your correct contact details.
The length of time that patients spend in Critical Care varies a lot. Patients who are admitted for close monitoring after an operation might only need to stay in Critical Care overnight or for a few days. Other patients might require Critical Care treatment for weeks or even months.
It is often very difficult to know how patients will respond and how quickly. We know that this can be very unsettling and we will always try to keep you updated.

What your friend or relative may look like
Patients may have:
- Breathing support (oxygen mask or breathing tube)
- Tubes in their neck or arm for monitoring or giving medication
- A monitor showing heart rate, blood pressure and oxygen levels
Staff will explain what they are doing, even if the patient seems unconscious, as some people can still hear and may remember later.
Often patients in Critical Care are sedated. There are a number of reasons why patients may need sedation, including if patients require the help of a ventilator for breathing.
What you can do to help
Even if your loved one appears asleep or sedated, talking to them can be comforting.
You can:
- Share memories
- Read from a book or magazine
- Bring small personal items or photos
You may also be asked to complete a “This Is Me” form so we can get to know them better.
Families are welcome to take part in simple care, such as applying moisturiser or brushing hair — please ask the bedside nurse if you wish to help.
