Correct Answer » D Explanation |
 |
– Bain circuit is a coaxial modification of Mapleson D.
– Fresh gas flows through the inner tube; expired gases pass outer tube.
– It suits spontaneous respiration but needs high fresh gas flow.
– More efficient for controlled ventilation due to low resistance.
– Mapleson A best for spontaneous breathing.
– Mapleson D best for controlled ventilation.
– Bain circuit is a lightweight, low-resistance coaxial Mapleson D.
