Description
PR4-g
Lung Ventilator for Transport and Emergency
The portable Lung Ventilator PR4-G was developed with advanced technology for use in intra and
extra hospital transportations, aeromedical rescue or emergency rooms, caring for adult, pediatric
and neonatal patients.
With volumetric and pressumetric controls, it presents in real time, through its LCD graphic
display, the visualization of all reading parameters, digital manometer and graphic of pressure by
time. It has adjustments of controls and alarms in its panel, of easy operation, facilitating the
control of the parameters to the operator
VENTILATION MODES
ADULT / PEDIATRIC
VCV assisted / controlled
PSV/CPAP
SIMV(VCV) + PSV
SIMV(PCV) + PSV
NEONATAL
PCV assisted / controlled
AUTOPEEP
With the AutoPEEP Ventilatory Mechanic, PR4-G evaluates the persistence of positive alveolar pressure at the end of the expiration, due to a final expiratory pulmonary volume higher than the foreseen functional residual capacity. The Auto P E E P occurs as consequence of the exhalation time being insufficient for the complete exhalation of the
patient.
INTERFACE AND VENTILATION MODES
With an LCD display of 7”, PR4-G holds a friendly and intuitive graphical interface, which allows the visualizaton of the ventilatory parameters and the curve of pressure by time. It is also composed of a large range of assisted
and controlled ventilatory modes capable of serving all patients, in an agile and easy to understand way.
NEONATAL MODE
The PR4-G is one of the most versatile transport ventilators in the market and may ventilate all patients, including newborns from 300g. With ventilatory modes such as continuous flow and nasal CPAP, and safety tools specific for the little ones, the PR4-G guarantees a proper ventilation for Neonatal
APPLICATIONS
PR4-g is a portable microprocessed lung ventilator which attends adult, pediatric and neonatal patients. The device is proper for versatile uses in intra and extra hospital mobile units, aeromedical rescue or emergency care.
