General information


  • ​Single limb design creates a self contained, thermally efficient atmosphere wherein inspired gases are naturally warmed and humidified. 


  • The Universal F transforms easily from an anesthesia delivery system to a transport unit, and if necessary, to a resuscitation circuit thereby increasing the quality of patient care and decreasing the number of products needed to serve a patient.


  • Within the Universal F circuit, the inspired gases are warmed and humidified by the patient’s expired gases.
  • Clear housing at patient and machine connections allows for visualization of circuit function and patient condition.
