| Key Benefits
- Testing procedure is easier by eliminating the
need to
correct for continuous bias flow.
- The Direct Connect preVent™ Pneumotach is the
first
metabolic assessment interface to allow direct
measurement of a patient’s metabolism without
compensating for, diverting or turning off bias flow.
- This advance in metabolic assessment allows early and
improved nutritional management of ventilator patients
on
a wide range of ventilators typically found in the ICU
/ CCU.
- Optimizing nutritional states has been proven
to decrease
the number of ventilator days and, ultimately, to the length
of stay in the ICU. This translates into improved patient
outcomes and significant cost savings to the health care
facility.
Key Features
- Simple setup: The design saves time and eliminates
hassles
associated with more complex flow measuring devices.
- Unsurpassed accuracy and reliability: Directly measures
gas exchange without the need for correction factors,
complicated connections or isolation valves.
- Great efficiency: The Direct Connect preVent™ Pneumotach
is the only completely disposable pneumotach on the
market. Eliminate the concern over infection control and
allow quick exchange between patients.
“Snap-in & Snap-out”.

It is a revolutionary flow device for unparalleled accuracy
and infection control for metabolic assessment of ventilated
patients.
