Turning the ventilator on • Start the ventilator by pressing the button on the right side of the device

• Then the following welcome screen appears : To display the results of the last manual test To set a ventilation for children

To set a ventilation for adult

Ventilation selection •

Once the patient configuration has been chosen, the following screen displays in order to choose the ventilation mode :

Volumetric mode

Pressure modes

•

Once the mode has been selected, the screen of parameters setting appears

Ventilation modes : (A)PCV

• (A)PCV = Assisted Pressure-Controlled Ventilation The ventilator delivers cycles characterized by a fixed insufflation's time and pressure parameter

© ResMed

–

PCV = cycles are released by the ventilator, insufflation does not depend on patient’s effort. A frequency should be adjusted.

–

APCV = inspiration can be released by the patient (trigger)

–

The change from PCV to PACV mode depends on inspiratory triggers adjustment

Ventilation modes : (A)PCV • On (A)PCV mode, the parameters to set are :  FiO2  Inspiratory Pressure  Positive End Expiratory Pressure (PEEP)  Frequency  Inspiratory time  Trigger level  Inspiratory slope

© ResMed

Ventilation modes : (A)PCV

• Therapeutic indications : As the pressure is controlled, P(A)CV mode is particularly recommended if there is a risk of barautroma or lung infection that could obstruct respiratory tract (inhalation pneumopathy) As the end of inspiratory time is imposed on the patient, the P(A)CV mode could sometimes be uncomfortable because it is not very adapted to the patient’s needs This mode is recommended at the beginning of weaning to facilitate the adaptation of the patient to the ventilator

–

CV = cycles are released by the ventilator, insufflation does not depend on patient’s effort. A frequency should be adjusted.

–

ACV = inspiration can be released by the patient (trigger)

–

The change from CV to ACV mode depends on inspiratory triggers adjustment

Ventilation modes : (A)CV

• On (A)CV mode, the parameters to set are :  FiO2  Tidal Volume  Positive End Expiratory Pressure (PEEP)  Frequency  Inspiratory time or I/E ratio or Maxi flow  Trigger level

© ResMed

Ventilation modes : (A)CV

• Therapeutic indications : The CV mode is recommended when it is better the device totally substitutes itself for the patient ventilation The ACV mode is particularly recommended for patients whose ventilation needs could be changed (volume control). It helps to adapt the patient to the ventilator. The setting of volume and frequency alarms is very important in order to avoid hyperventilation risks (exaggerated patient’s demand)

Ventilation modes : PS

• PS = Pressure Support This mode is a pressure mode assisting the patient’s spontaneous breathing

•

Principle : The beginning and the end of the inspiratory cycle are initiated by the patient. However, Elisée 250 is provided with a minimum frequency parameter : if the number of patient initiated breaths is lower than Fmini, the ventilator releases support breaths.

© ResMed

Ventilation modes : PS •

PS mode also allows to set an apnea time at the end of which the ventilator switches to backup apnea ventilation if the patient does not initiate a breath

•

If the patient initiates a breath afterwards, ventilation switches back to Pressure Support

Apnea ventilation = Exclusive to Elisée 250 ! © ResMed

Ventilation modes : PS • On PS mode, the parameters to set are :  FiO2  Pressure Support  Positive End Expiratory Pressure (PEEP)  Trigger level  Inspiratory slope  Maximum inspiratory time

• The adjustable parameters of apnea ventilation are :  Apnea Time  Tidal Volume  Frequency  Inspiratory time or I/E ratio or Maxi flow
