Applications
OptiVent™ is an electro-medical device for the completely automated management of the multi-functional Nutrivent™ nasogastric probe.
Among these operations are included:
• system calibration;
• setting of the pressure zero;
• support to the positioning of the nasogastric probe;
• periodic and automatic inflation and deflation of the balloons on the nasogastric probe,
• registration in continuous mode of the pressures supplied, data graphic and numeric display;
• storage of patient data;
• transfer of the data registered on the computer.
The equipment is provided with a practical touch screen interface for an immediate input of the requested data and for a simple interaction with the system.
OptiVent™ allows to register and monitor, in continuous mode, basic parameters in the management of the critical patient: transpulmonary pressure (Ptp),, Elastance (E), Compliance (C), inspiratory effort, endoabdominal pressure Pga (with NutriVent™ provided with two balloons), transdiaphragmatic pressure (with Nutrivent™ provided with two balloons).
The registration of the esophageal pressure allows to split Elastance and Compliance into their components: of the whole respiratory system (Ers, Crs), of the lung (EL, CL). of the chest (Ecw, Ccw).
System calibration
During this operation, the software
inside the device determines the
most suitable inflation volume of
the esophageal balloon for the single
patient.
The balloon is inflated at different
volumes and the software sets
the best volume for the optimal
transmission of the pressure signal
from the patient to the equipment.
Moreover, the system corrects the
signal registered by eliminating the
cardiac and esophageal artefact.
Support to the positioning of the nasogastric probe
In order to have a good reading
of the pressures, it is important
that the balloons are properly
positioned: the esophageal balloon
in the third medium/lower
of the esophagus; the gastric
balloon (if available) in the
stomach.
In the intubated patients with
spontaneous respiratory activity,
it is absolutely possible to
define if the position of the esophageal
balloon is appropriate
by performing an occlusion of
the respiratory tract and checking
that the variations of the esophageal
pressure comply with
the ones of the respiratory tract.
Registration in continuous mode of the pressures supplied, parameter
calculation and their display
On the screen of the equipment
are displayed two traces, which
can be of pressure (esophageal,
gastric, respiratory tract), of
flow or of volume. The two traces
can be selected by the user.
By simply pressing a button, it is
possible to recall the summarizing
screen page of the ventilator
parameters, in all their components.
