1.1 What is the Vivo 40?
The Vivo 40 is a pressure-supported and pressure-controlled ventilator.
It has three modes of operation: PCV
(Pressure Control Ventilation)
, PSV
(Pres-
sure Support Ventilation)
and CPAP
(Continuous Positive Airway Pressure)
. The
PCV and PSV modes have an adjustable inspiratory trigger sensitivity setting
which allows the patient to initiate ventilator-assisted breaths.
• In the PCV mode (Pressure Control Ventilation), the ventilator provides
assisted or controlled pressure-regulated breathing. In PCV mode, the clini-
cian sets an inspiration time. The inspiratory pressure is set by the IPAP
(Inspiratory Positive Airway Pressure) setting. The end-expiratory pressure
is set by the EPAP (Expiratory Positive Airway Pressure) setting.
• In the PSV mode (Pressure Support Ventilation), the ventilator’s expiratory
trigger can also be adjusted allowing the ventilator to more easily match
each patient’s needs. The inspiratory pressure is set by the IPAP setting. The
end-expiratory pressure is set by the EPAP setting.
• In the CPAP mode (Continuous Positive Airway Pressure), the ventilator
provides a continuous positive airway pressure.
The Vivo 40 has a pressure sensor that continuously monitors output pressure
to the patient and reference ambient pressure, so that the device automatically
will compensate for altitude changes.
The internal memory of the Vivo 40 can be downloaded to a PC where you can
view the patient compliance data in the Breas Vivo PC Software.
1.2 Intended Use
The Vivo 40 is an assist ventilator intended to augment the breathing of spon-
taneously adult patients >66 lbs (>30 kg) suffering from respiratory failure, res-
piratory insufficiency, or obstructive sleep apnea.
The Vivo 40 is not intended to provide the total ventilatory requirements of the
patient.
The Vivo 40 is intended to be used for both invasive and non-invasive applica-
tions.
