The critical care team is the multidisciplinary group of health professionals responsible for the assessment and treatment of patients with life-threatening illness or injury. Critical care (also called intensive care) wards provide continuous monitoring and advanced organ support for patients who require more intervention than can be delivered on a general ward.
The team is led by a critical care consultant (intensivist), a doctor with specialist training in managing complex, unstable patients. Nurses are central to critical care delivery, with staffing ratios typically one-to-one or one-to-two to allow close observation and rapid response. Additional team members commonly include physiotherapists (supporting breathing and early mobility), pharmacists (optimising medication and monitoring for interactions), dietitians, speech and language therapists, and clinical psychologists.
For cardiac arrest survivors, the critical care team manages the immediate post-arrest period. This includes targeted temperature management, haemodynamic stabilisation, ventilator support if the patient cannot breathe independently, and investigations to identify the cause of arrest. The team works alongside cardiologists to interpret monitoring data and make decisions about interventions such as coronary angiography or implantable cardioverter defibrillator insertion.
A stay in critical care can itself be a source of psychological distress. Patients may experience disorientation, hallucinations, or distressing memories of procedures. These experiences can contribute to post-intensive care syndrome (PICS) and PTSD. Many units offer follow-up clinics after discharge to support recovery and address ongoing physical or psychological needs.
