Abstract
A trap for collecting liquid in a gas line between the patient and a respiratory gas analyzer which trap senses the collection of a predetermined volume of liquid and operates upon sensing that volume to immediately interrupt the connection between the gas analyzer and the deposit of liquid and also to initiate a flushing cycle such that the liquid is flushed out of the lines to protect the analyzer from contamination.
