Explanation:
Detailed explanation-1: -Rebreathing circuits use a carbon dioxide absorber to trap and remove CO2 so the patient can breathe gases that have been recycled through the machine. Non-rebreathing circuits use high gas flows to washout expired CO2 from the circuit before the patient takes its next breath.
Detailed explanation-2: -All non-rebreathing (NRB) circuits lack unidirectional valves and soda lime carbon dioxide absorption.
Detailed explanation-3: -Non-rebreathing systems are most useful in small patients (less than 5 to 10 kg) but require higher O2 flows which increases consumption of anaesthetic and causes more waste of anaesthetic (environmental pollution).
