DEVICE DESCRIPTION
The e360 ventilator employs a dual servo gas delivery system
(one each for air and oxygen), a servo controlled active exhalation
valve, and a combination control panel interface and touch screen
interface/ graphics monitor (GUI). The electronically-controlled inlet
gas mixing system is superior to traditional pneumatic mixers that
must exhaust gas from the system to consistently deliver precise
oxygen concentrations. The dual servos respond immediately to
change the delivered F
I
O
2
when requested by the control system.
Approximately 60 minutes of operational backup power is available
when the ventilator’s internal battery is fully charged. In addition,
the e360 ventilator has remote alarm, external battery, VGA and
external alarm silence connections plus an RS232 interface to
connect to central monitoring systems and USB port for uploading
software.
When the e360 ventilator is turned on, the Power On Self-Test
(POST) verifies the integrity of the software and hardware of the
ventilator and the ventilator is in Standby until the user selects
Start Ventilating. During operation, the ventilator performs regular
pressure transducer calibrations and software tests to ensure
accuracy of monitored and displayed data. A user initiated Circuit
Check performs a leak test of the breathing circuit system and
measures circuit compliance and resistance. User initiated sensor
calibration tests allow for calibration of the O
2
and Exhalation Flow
Sensors.
All breath types and modes include a range of ventilation and
alarm settings appropriate for adult or pediatric/infant patients. The
e360 ventilator has settable alarm limits for high and low peak
airway pressure, high and low expiratory minute ventilation/ back
up ventilation, high respiratory rate, disconnect threshold and
apnea.
There are built-in alarms limits for O
2
monitoring, low
baseline pressure, high baseline pressure, sustained high baseline
pressure, gas supply failure, device alert and power switchover
.
The e360 ventilator monitors and displays the power source,
volumes, peak flows, breath timing parameters (I:E ratio,
respiratory rate, and inspiratory time), delivered oxygen
concentration, and patient pressures (peak, plateau, mean airway,
and baseline).
The e360 ventilator has a built in oxygen analyzer that can be
calibrated with a push of a button.
During exhalation, the e360 ventilator uses a bias flow to flush
exhaled CO
2
and stabilize temperature, humidity, and baseline
pressure in the patient breathing circuit.
A
stable baseline pressure
between breaths helps to minimize auto-triggering.
