Abstract
A method for coupling ventilator breathing circuit tubing to a respiratory ventilator using a compression coupler. The tubing has a corrugated or ribbed portion and a non-corrugated cuff. The cuff is inserted into the coupler, which is in turn coupled to the ventilator. The coupler has inner and outer tubular members that compressively engage the cuff between them when they are rotated with respect to one another.
