Newport e360 - Safety Features

Volume. The set Tidal Volume is not guaranteed for each breath, it
is a target.
The target pressure of the first breath, when no target pressure has
been established is PEEP/CPAP + 5 cmH
2
O/mbar.
Safety Features
• Protection From Over Pressurization
• Protection From Re-breathing Exhaled Gases In Case of
Ventilator Shutdown
The e360 Ventilator software allows the user to perform a pre-use
leak, compliance and resistance tests of the patient breathing
circuit, humidifier and filters. Other software based selections
include: breathing circuit compliance compensation of flow/volume
delivery and monitoring On or Off, circuit type in use (heated
expiratory limb (high output), heated insp. expiratory limb (middle
output), or HME), leak compensation On or Off, set time and date,
and adjust for operation at the local altitude.
All modes of ventilation and breath types on the e360 Ventilator
include a range of settings appropriate for adult or pediatric/infant
patients. To maximize patient safety, the Control Panel has an
Accept Button that must be pressed to activate any setting changes.
This feature is to prevent accidental changes. The e360 has settable
alarm limits for high and low peak airway pressure, high and low
expiratory minute volume, high respiratory rate, circuit disconnect
threshold and apnea.
The Low Minute Volume Alarm activates Back
up Ventilation which increases respiratory rate in
A/CMV and SIMV
and provides pressure controlled ventilation according safe basic
settings in SPONT
mode in order to increase ventilation back to
acceptable values during the alarm condition. In addition, 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.
If a condition, such as low battery power during battery operation
or component malfunction, occurs and the ventilator cannot
maintain reliable operation, it declares a Device
Alert alarm.
This
alarm cannot be silenced without first powering off the ventilator.
An
Alarms and Message Bar on the GUI clearly displays all alarm
and informational messages. An alarm lamp on the top of the device
lights with all alarms. It can be viewed from 360º. In addition, a
separate control panel indicator lights in case of a Device Alert.
The exhalation system is heated to prevent moisture in the
exhaled gas from being condensed in the exhaled flow monitor
system. It features low exhalation flow resistance to allow rapid
return to baseline pressure after a positive pressure breath, and
