RAH ICU dietitians also have a key role in leading clinically focused nutrition research and have extended scope of practice to place post-pyloric feeding tubes at the bedside.

Physiotherapists are key members of the ICU team who routinely review ICU patients during their stay.

The supportive therapies delivered by physiotherapists have been shown to enhance patient rehabilitation and outcomes during and after critical illness.

Physiotherapist treatments may involve:

• Listening to the chest and helping to clear the lungs
• Maintaining a range of limb movements and mobility in bed with stretches
• Strengthening exercises and helping with movement, such walking and transfer out of bed into a chair. This is important when patients are unwell to prevent deconditioning during critical illness.
