The Surfair 365 System

Designed for First Responders


Featuring the Spirit 3200 Ventilator

The ‘SPIRIT 3200 VENTILATOR’ is designed with state of the art components that are more accurate and provide increased reliability. The software provides operational functions to give even the most experienced Respiratory Therapist the precision and settings needed for the most delicate situation. At the same time, the most inexperienced personnel can enter simple patient data and the unit can calculate typical parameters to save lives until more experienced personnel can take over. Patented safety features that are absent on other ventilators just may make this the safest ventilator available.
