Instructions for use MONSOON 5.6e

Using the MONSOON with Single Lumen Catheter
Caution: Limited space may not always allow the use of a Jet catheter with second lumen
for continuous pressure monitoring or capnography. For this reason the MON-
SOON features a built-in pause pressure monitor.
It monitors the pressure still present in the respiratory tracts after applying the
Jet pulse. This determines whether the respiratory tract pressure has decreased
during expiration.
This safety feature provides reliable protection from patient barotrauma. To en-
sure this safety feature is effective the Jet frequency must be higher than 80
CPM. At a Jet frequency below 80 CPM the volume of a single Jet pulse may be
big enough to cause barotrauma.
The following graphic illustrates the PP (Pause Pressure) measurement:
