“The Universal Breathing System is an efficient means of heating anaesthetic gases and preventing heat loss during anaesthesia.” Carson KD, Casey WF. The Universal F Circuit –A Novel Breathing System for heat Conservation During Spinal Surgery. World Congress – Abstract. 1996.

The Universal F/F2 assists during acute care. Batcheller D. The Impact of Fast Trac Weaning and Cost Containment in the Acute Setting. Respiratory Care, October 1999, Vol. 44, No. 10.

The Universal F breathing system is an efficient cost-effective means of maintaining body temperature during surgery. Thompson M, Rast R, Carson K. The Universal F Breathing System Reduces the Number of Hypothermic Patients Entering the PACU. North Florida Study. World Congress. 1996.

The abstract looks at how to protect the cilia from damage due to under humidification. The results show that the Universal F circuit is able to keep the cilia from damage when a two limb circuit can not. Branson R, Campbell R, Davis K, Porembka D. Anaesthesia Circuits, Humidity Output, and Mucociliary Structure and Function. Anaesthesia and Intensive Care, Vol. 26, No. 2, April 1998.

A study of the Universal F2 (Vent F2) in the ICU to compare airflow resistance and internal compliance to a generic two limb circuit. Branson R, et al. A Laboratory Comparison of the Vent F2 Breathing Circuit. AARC – Poster. 2000.
