Chapter 1: For Your Safety and that of Your
Patients
The Alberta E-Vent is an electrically driven automated resuscitator
based on the robotic operation of a Health Canada and ISO approved
Bag Valve Mask Assembly (BVM, e.g. Ambu SPUR II). It is designed and
built to rapidly support health agency ventilator shortages caused by
the Covid-19 pandemic. The device design was inspired by the
Massachusetts Institute of Technology (MIT) E-Vent, and automates a
manual ISO approved biocompatible resuscitator to expand
functionality and achieve consistent operation.
1.1. Safety Information
Please review the following safety information prior to operating the
Alberta E-Vent. Attempting to operate the Alberta E-Vent without
fully understanding its features and functions may result in unsafe
operating conditions.
General Warnings and Cautions applicable to the use of the Alberta E-
Vent under all circumstances are included in this section. Specific
Warnings and Cautions are also found within the manual.
If you have a question regarding the installation, set up, operation, or
maintenance of the Alberta E-Vent, contact the COVID Client
Coordinator, as shown in Appendix A.

Alberta E-Vent User Manual Version 1.3 June 3, 2020 2
1.1.2. Warnings
WARNING!
Strictly follow these Instructions for Use.
Any use of the product requires full understanding
and strict observation of all portions of these
instructions.
The device is only to be used for the purpose
specified under "Intended Use" and in conjunction
with appropriate patient monitoring. Observe all
WARNING and CAUTION statements throughout
this manual and all statements on device labels
▪Alberta E-Vent can only be used by a trained
clinician, under a qualified physician direction.
▪When the Alberta E-Vent is connected to a
patient, a trained clinician must be in
attendance at all times to react to an alarm or
other problem indications and that can
manually ventilate the patient in case of failure.
▪The Alberta E-Vent does not contain a backup
power source but will alarm if disconnected
from power. Whenever connected to the
patient, it must be plugged into a receptacle
attached to an uninterruptable power source if
continuous operation is required.
▪The BVM has operating limitations. The bag
must be replaced:
-Anytime a healthcare professional notices
abrasion on the bag or,
-If the bag does not fully re-inflate after
the Alberta E-Vent arms are fully
extended.
▪As the BVM is the primary resuscitation device,
and as with other positive pressure ventilation
devices, the lungs are force inflated with
pressurized air or oxygen and can inherently
lead to risk of various complications such as
over inflating or over pressurizing the patient
and related injury, such as gastric insuffation,
volutrauma barotrauma., etc.
▪A source gas failure will change the FIO2 and
may result in patient injury. The Alberta E-Vent
does not monitor gas input or concentrations.
▪Do not touch electrical connectors of the
ventilator or accessories, and patient
simultaneously.
▪Due to possible fire hazard, the ventilator
cannot be used in the presence of volatile
anesthetics or an oxygen-rich environment.
Device can only be used in well ventilated,
general purpose electrical environments.
▪An audible alarm indicates an anomalous
condition and must always be investigated
immediately.
▪If a mechanical or electrical problem occurs
while operating the Alberta E-Vent, it must be
removed from use and referred to qualified
personnel for servicing. Using a faulty Alberta
E-Vent may result in:
-clinician injury or,
-patient injury or death.
▪The Alberta E-Vent functionality may be
adversely affected by or may adversely affect
the operation of other equipment nearby,
including but not limited to:
-high-frequency surgical (diathermy)
equipment,
-defibrillators,
-short-wave therapy equipment,
-“walkie-talkies” and similar transmitting
radio equipment, and
-cellular phones.
▪Electric shock hazard - Do not remove any of
the Alberta E-Vent covers or panels.
▪A protective ground connection by way of the
grounding conductor in the power cord is
essential for safe operation. Upon loss of
protective ground, all conductive parts
including knobs and controls may cause an
electric shock. To avoid electrical shock:
-plug the power cord into a properly wired
receptacle,
-use only the power supply cord supplied
with the ventilator,
-ensure the power cord is not abraded and
is in good condition.

Alberta E-Vent User Manual Version 1.3 June 3, 2020 3
1.1.3. Caution
CAUTION!
The following cautions apply any time you work with the
Alberta E-Vent.
▪Ensure that the voltage selection and installed fuses or
breakers are set to match the voltage and ampacity of the
wall outlet, otherwise damage may result.
▪Do not submerge the Alberta E-Vent or pour cleaning
liquids over or into the Resuscitator Mechanism or the
electric casing.

Alberta E-Vent User Manual Version 1.3 June 3, 2020 4
Chapter 2: Intended Use
The Alberta E-Vent is an automated resuscitator
intended for short-term respiratory support,
monitoring and treatment of adult patients when a
conventional ventilator is unavailable. It allows
hospitals to expand their patient care capacity and
reallocate conventional ventilators to sophisticated
needs patients.
The Alberta E-Vent does not have the functionality
of a full feature ventilator. It can be used as a
replacement to manually compress the BVM only if
absolutely necessary where full-feature ventilators
are unavailable, staff are unavailable to attend a
manually operated BVM, and only under the
supervision of a clinician.
The Alberta E-Vent can only be used for Patients:
▪18 years of age or older
▪require a tidal volume less than 860 ml
▪require peak inspiratory pressures of less than
45 cmH20
▪require less than 30 breaths per minute in
Volume Control mode, or 18 breaths per
minute in Assist Control mode
▪with a lung compliance greater than 10 ml/cm
H2O
▪accept the risks of the limitations of the
emergency functionality of the Alberta E-Vent
and where an experienced clinician is trained
on the Alberta E-Vent and can supervise its
operation
▪not recommended for Acute Respiratory
Distress System (ARDS) patients
▪are located in a well-ventilated environment
where a concentration of Oxygen below 25% is
maintained.
The Alberta E-vent has only been tested with the
Ambu® SPUR® II - Disposable Resuscitator (REF
520211000). The results of the testing are only
valid for this particular brand of BVM. While other
BVM’s can be used, the user must conduct their
own tidal volume mapping and verify that the
device performs as expected with respect to all
user settable parameters. Using other brands of
BVMs are done so at the risk of the operator and
patient.
2.1. System Configuration
The Alberta E-Vent is composed of the Resuscitator
Mechanism, the Programmable User Interface (UI)
and electronics, and the Ventilation Circuit. It is
designed for simplicity of operation and setup.
While full-feature ventilators have multiple
adjustments for various operating and alarm
parameters to accommodate all patients, the
Alberta E-Vent automated resuscitator adjustments
are limited to six key items to accommodate the
majority of patients. The following six operational
parameters are available for adjustment once the
Alberta E-Vent warm-up sequence has completed:
1. Ventilation Mode (volume or assist control)
2. Alarm Set Points (PIP High/Low Limit, PEEP
High/Low Limit and Respiratory Rate Alarm)
3. Tidal Volume
4. Respiratory Rate
5. Inspiration Time
6. Trigger Pressure
2.2. Features and Functions
▪The Alberta E-Vent operates in two different
modes –Volume Control and Assist Control.
▪Two operational displays: operational settings
(Left) and alarm settings (right).
▪A large red remote display to enable clinicians to
remotely observe key indicators from the
observation room.
▪A button and scroll wheel system are used to set
and confirm all operational and alarm settings.
▪Adjustable alarms enable attending clinicians,
respiratory therapists, and nurses to set alert
limits.
▪An emergency stop button to immediately
disable the Alberta E-Vent.
▪Inspiration and expiration cycles are indicated
through LEDs. The operator can quickly glance at
the Alberta E-Vent and determine the current
ventilation state.

Alberta E-Vent User Manual Version 1.3 June 3, 2020 5
▪Electronics are housed in an all metal enclosure
to suppress Electrical Magnetic Interference
(EMI) from surrounding devices and
environment.
▪A membrane covers the user interface and
control box to facilitate Alberta E-Vent surface
cleaning, sterilization and prevent debris and
other materials from penetrating into the
enclosure
▪A Splashguard for the Resuscitator Mechanism to
reduce the risk of contamination.
2.3. Disclosures / Deficiencies
▪This is an emergency device. If the device
malfunctions and no immediate fix is available,
shut the machine off and immediately follow
standard patient care procedures and switch to
manual ventilation.
▪Shelf life or durability testing has not been
conducted on the Alberta E-Vent.
▪Oxygen, Heliox, and air supply are not supplied.
The Alberta E-Vent BVM draws air from the
surrounding environment and can be connected
to an externally titrated, blended and supplied
oxygen source. There is no FiO2 indication or
alarm.
▪Patient pathology determines who can use this
device and length of treatment time to avoid
post-use complications. The clinician must be
aware of all the Alberta E-vent’s limitations
before authorizing its use. For example, the tidal
volume operational range is narrower than full-
featured ventilators and accommodates a
narrower range of patients.
▪The Alberta E-Vent and its components are
provided in a clean condition and should be
disinfected before use by the professional
healthcare facilities using their own disinfection
methods and procedures.
-BVMs and Ventilation Circuit hoses and
valves are supplied by the healthcare
facility.

4.3. Hospital Supplied Accessories
4.3.1. Uninterruptable Power Supply (UPS)
The Alberta E-Vent will not function if a loss of
power occurs, although it has been designed to
alarm clinicians in the event that it is no longer
receiving power. Hospitals have the option to add a
UPS to the system in order to guarantee reliable
power in the event of a blackout or if they need to
transport the patient.
4.3.2. FiO2 Monitoring Devices
The Alberta E-Vent does not contain an FiO2
monitoring system. FiO2 requires an external FiO2
analyzer such as the MySignO, which has a
measuring range of 0-100% oxygen and accuracy of
< 1%.
4.3.3. Air Oxygen Blender
Hospitals may also wish to use a blended gas
source for FiO2 control as opposed to the supplied
FiO2 table (Appendix B). Canadian Hospital
Specialties offers a blender (MX120E-AIR/02-DS)
that offers a range of 5-120LPM, which would be
required for this purpose.
