STILL, the Most Innovative and Versatile Coaxial System that...

• Protects both inspiratory and expiratory machine ports with a single, dual-chamber, high efficiency filter• Helps maintain patient body temperature as reported in independent studies1,2,5

• Reduces the torque on the airway device, because the lightweight flex tubing can be: > Custom shaped near the airway > Expanded to the ideal length between patient and machine to minimize draping

• Reduce the number of circuit lengths stocked, due to flex tubing that expands to multiple lengths

• Minimizes circuit types stocked, because the Flex2 can be used wherever an adult or pediatric two-limb

is used > Whenever an adult or pediatric two limb is used the effective inner and outer diameter is

equivalent to a standard two limb pediatric circuit.

> Elbow of the Flex2 has no more dead space than a pediatric 2-limb wye

• Requires significantly less storage space, because flex tubing is packaged at its most compressed length

Coaxial breathing circuit

• Produces less overall disposable waste for the hospital when using Flex2 for surgery, transport, and the PACU• Can provide lower cost options when using the Flex2 for surgery, transport, and the PACU

Protects Both Patient and Machine

KingFlex2 Filter and HME Performance Data5,6

* Bacterial efficiency determined per test method ASTM F2101, which simulates the actual airborne transmission of Staphylococcus aureus in water droplets.6

** Viral efficiency determined per test method ASTM F2101, which simulates the actual airborne transmission of bacteriophage phi x174 in water droplets.6

*** Particulate efficiency determined per Nelson Laboratories’ test protocol, which transmits dry and inert 0.3um airborne particulates. An efficiency of >99.97% is a requirement for a filter to be rated as HEPA.4
