Patient circuits

The Astral device supports single and double limb circuits with the use of interchangeable circuit adapters.

Breathing circuits may be of 10, 15 or 22 mm diameter. For recommended patient circuit components and compatible accessories, refer to www.resmed.com/astral/circuits.

There are three circuit adapters:

circuit
2. Single limb | Single limb circuit with expiratory valve (expiratory valve integrated into the circuit)
3. Double limb (Astral 150 only) | Double limb circuit (expiratory valve integrated into the adapter) OR single limb circuit with intentional leak or Mouthpiece circuit
