When you think about working in Intensive Care Unit (ICU) that too in the NHS, a different healthcare system you may not be accustomed to, you may naturally feel some apprehension. You're looking to deal with the patients who have been deemed the sickest in the hospital. They will be receiving different types of support in order to keep them stable; it could be blood pressure, ventilatory, sedation, etc.
What can you expect?
Patients on ICU require a high level of care and observation. These are patients who are deemed to be well enough when not in hospital to the point that ICU care is appropriate. There should also be something that ICU is offering that cannot be given on the ward (ex: administration of potassium via a central line, intubation and ventilation, etc).
