Frequently Asked Questions

UPDATED: JANUARY 14TH, 2021

TECHNICAL

Which power sources are required to use the MVM electrical and gas?


Electrical – AC mains supply 100 – 240 VAC, 50/60 Hz, 2.0-1.0 A

Pneumatic/gas - 30-100 PSI O2 + 30-100 PSI Air Supply.




Does the MVM have a battery backup in the event of an electrical failure?


Yes – the MVM’s Bel Power BPEU4035 power supply provides battery backup which automatically provides 12V DC power in case of a power outage. When fully charged, the battery provides 120 min of operational time. The functionality of the MVM remains unchanged after the switch-over to the internal battery power source and during the time it is recharging.




Which circuits can be used with the MVM Ventilator?


A list of compatible patient circuit components can be found in the user manual.




Can the MVM be used with a humidifier?


No.





GENERAL

Is the MVM ventilator Health Canada cleared or approved?


The MVM is authorized for use by Health Canada under the Interim Use authorization for ventilators, which authorizes its use for the duration of the COVID-19 public health emergency declaration justifying emergency use of these devices, unless terminated or revoked (after which the products may no longer be used).




Can the MVM be used for transport?


The MVM is not designed to be used for any kind of transport (intra hospital or inter hospital).




Can the MVM be used in the home?


The MVM cannot be used in a home setting.




Is it possible to use the MVM for non-invasive ventilation (NIV)?


No, the MVM cannot be used for NIV. The MVM is designed to ventilate intubated or for patients who have a tracheostomy.





USER SETTINGS

Which modes of ventilation are provided by the MVM?


The MVM provides two modes: Pressure Control Ventilation (PCV) and Pressure Support Ventilation (PSV).




What is PCV?


PCV is a time-cycled controlled ventilation mode in which the inspiratory pressure level is kept constant. A new inspiration is initiated either after a breathing cycle is over, or by patient request at any time during expiration.




What is PSV?


PSV mode is a flow cycled spontaneous mode in which the ventilator takes over part of the work of breathing, with the patient maintaining control of the respiratory rate. PSV is not suitable for patients unable to breathe spontaneously.




Can a patient be weaned from the ventilator using one of the modes?


A patient can be weaned from the ventilator using the PSV mode.




Does the MVM have audio and visual alarms?


The ventilator has high, medium and low priority audio and visual alarms.




Does the MVM have remote alarm capability?


The MVM has remote alarm capability.




How do I set the inspiratory time in PCV?


The inspiratory time is not set directly but is calculated based on the set rate and set i:E ratio.




Is the inspiratory trigger sensitivity (ITS) of ‘1’ easy or hard for the patient to trigger a breath?


‘1’ would be a setting that would be the easiest for the patient to trigger.




In PSV what does an Expiratory Trigger Sensitivity (ETS) of 30% mean?


A setting of 30% signifies that when the patients inspiratory flow decreases to 30% of their peak inspiratory flow, inspiration will end. The lower percentage that is set, the longer the inspiratory time of the breath.




What is occurring when the ventilator triggers independently of set rate or patient initiation?


There may be several reasons for ‘auto triggering’. The ITS setting may be too sensitive or there may be a leak in the circuit or patient interface (e.g. endotracheal tube).




Why can’t I immediately repeat an inspiratory or expiratory pause procedure?


There is a ‘time out’ of 60 seconds where activation between activation of inspiratory or expiratory pause procedures is prohibited.




What do I do if the screen turns completely red?


If this occurs in testing, prior to connecting the patient, power off the ventilator and power on after at least 20 seconds. Should this occur during ventilation – remove patient immediately and provide alternate means of ventilation.




In an emergency would it be possible to connect several patients to one ventilator using a ‘Y’ connector?


Vexos does not recommend the use of one MVM for more than one patient. To ensure appropriate and lung-protective ventilation, monitoring and ventilator settings need to apply for one patient only.
