Your stay

Critical care

Being admitted to critical care

It can take around 1 to 2 hours to settle you into the unit. 

We'll often give you sedation (medicine to make you sleep). This is to make sure you're comfortable while on a ventilator, or getting other treatment.

What it's like in critical care

The unit can be busy, with lots of activity and noise.

Please try not to let the noise and alarms concern you. If you have any questions, your bedside nurse will explain what the noises are and the treatment and equipment we use.

When you arrive on the unit we'll give you monitoring leads and equipment. This allows staff to watch your:

  • heart rhythm
  • blood pressure
  • oxygen levels in your blood

You'll often need a lot of rest to help you recover.

Your recovery

When you no longer need critical care treatment you'll leave the intensive care unit (ICU). You'll move to a high dependency unit (HDU) if you still need to be closely monitored, or to a ward.

Leaving ICU is usually a positive step. It can be difficult to adjust to no longer having one-to-one nursing. Ward staff will continue to support you in your rehabilitation. A member of our critical care team will check on you a few days after you leave ICU.

You'll usually spend time on a ward before going home. During this time our critical care team is available to provide advice and support.

We'll send a full report to your GP including any rehabilitation plan.

At home

If you have any health problems once you are home, please contact your GP.

Life after critical illness can be challenging and it's not always easy to get the help you need. We'll invite you for an appointment at our post intensive care recovery clinic. This will be 2 to 3 months after you leave hospital. 

You can also self-refer by calling 020 7185 6565 or emailing icuclinic@gstt.nhs.uk.

We have a peer support group. Former patients and families can meet each other, share their experiences and help make sense of life after critical illness. Please email icupeersupport@gstt.nhs.uk for more information.
