Health disciplines

Registered dietitian

Intensive care unit patients can have unique and complex nutritional and medical needs. A registered dietitian works with the entire ICU team, to advise and translate the science of nutrition care and intervention into patient specific, evidence-based nutrition care plans. Nutrition support may be provided in different ways: in the form of specialized oral diets, through a feeding tube (enteral nutrition), or by intravenous access (parenteral nutrition).

Occupational therapist (OT)

Occupational therapists are rehabilitation professionals who help patients with their independence and quality of life while they are in the ICUs. They address care aspects like patient positioning in the bed or chair, early cognitive and perceptual assessment, and adapting basic everyday tasks such as feeding and communication.  

Occupational therapy assistant (OTA)

The OTA assists the occupational therapist to teach patients how best to get back to their daily activities.


The pharmacist works with the nurses and doctors to manage all of the patients’ medications while in the hospital.

Physiotherapist (PT)

The physiotherapist helps patients move and become mobile early on to prevent weakness and promote independence through a range of motion and strengthening exercises, balance activities in sitting and standing, and gait training. The physiotherapist may use manual techniques to help clear secretions from the lungs as well as teach deep breathing and coughing techniques. Along with the other team members, the physiotherapist helps the patient and family transition to the unit and create a safe discharge plan as appropriate.
