Eolife® Ventilation Method - ARCHEON EOlife Instructions D'utilisation

Connect the ventilation interface (mask or endotracheal tube) to the compatible end of the FlowSense® sensor The
sensor ends are shaped differently to ensure that the interface cannot be connected to the wrong end
Connect the bag to the other end of the FlowSense® sensor The device must be assembled as shown below:
Disassembly
To remove the accessories from the product, take the FlowSense® sensor out of the ventilation interface (mask or
endotracheal tube) by gently pulling vertically on the FlowSense® sensor Then remove the ventilation bag at the
other end in the same way
Caution
If the patient is intubated and secretions appear in the FlowSense® sensor during ventilation: remove the sensor very
carefully from the endotracheal tube (or other supraglottic airway device) by holding the tube firmly with one hand
and gently pulling the FlowSense® sensor upwards with the other hand to disconnect it from the tube
b) EOlife® ventilation method
EOlife® gives the user real-time feedback on the quality of the ventilation performed on the patient based on
a cyclic analysis of inspiratory and expiratory flow rates It must therefore be positioned proximally to be able to
measure both the inspiratory and expiratory flow rates, calculate the volumes insufflated and expired, the ventilation
frequency and leakage, estimate the tidal volumes, and generate user information signals and alarm signals if the
ventilation parameters are unacceptable
EOlife® also uses algorithms to filter out small airflows generated by chest compressions so as not to display
anomalous volume and ventilation frequency values and to avoid measurement artefacts During ventilation, be sure
to generate enough flow to be detected by the device
Warning
When ventilating a patient with a mask, ensure it is correctly held on the patient's face during insufflation and for the
entire duration of expiration so that EOlife® can measure the volume expired
Note
If used for training on a manikin, check that the manikin's airways are completely sealed so that all of the
air insufflated via the mouth is fully expired If this is not the case, EOlife® will not be able to analyse the
ventilation cycles or calculate the ventilation parameters correctly
The main screen guides the user by displaying the ventilation parameters (advanced interface) or ventilation
instructions (basic interface) and visual indicators showing the ideal air/oxygen volume to administer and when to
administer it The main screen also uses alarm signals to warn the user if the patient is not ventilated correctly

1. Displays the patient height selected and quick access key to change the patient's height
2. Displays the chosen resuscitation mode and quick access key to change the resuscitation mode
3. Rotation icon and key to rotate the screen 180° to adjust the direction of the screen to the user's position during
ventilation
The user can perform ventilation and change the patient's height or the resuscitation mode in this position
The screen returns to its normal position if the user:
•
Presses again on the rotation icon
•
Presses the physical ON/OFF button to show the summary screen
•
Presses the physical ON/OFF button for 3 seconds to switch the device off
4. Displays the battery level (between 0% and 100%)
o See "IX 3 a) Charging the battery"
5. On the advanced interface: displays the actual volume insufflated (Vi) for each ventilation cycle (value in mL)
6. On the advanced interface: displays the tidal volume (Vt) (value in mL):
o For 30:2 mode → mean tidal volume based on the two consecutive ventilation cycles
o For continuous mode → actual value of tidal volume at each ventilation cycle
Note
The tidal volume is the estimated volume of air/oxygen actually reaching the patient's lungs based on both
the measurement of the volume of air expired and the leakage calculated during the insufflation/expiration
phases
The ERC and AHA recommend that an adult patient in cardiopulmonary arrest should be ventilated with a
tidal volume of 6 to 7 mL/kg-1 of theoretical ideal weight, i e a volume of around 420 to 490 mL for an average
adult weighing 70 kg
7.
On the advanced interface: displays the trend value of the ventilation frequency (Freq ) (breaths/minute) taking
into account the frequency of the last ventilation cycles performed:
o For the 30:2 mode → value available from the fourth ventilation cycle
o For the continuous mode → value available from the second ventilation cycle
Note
The ERC and AHA recommend that an adult patient in cardiopulmonary arrest should be ventilated at a
frequency of 10 breaths per minute during continuous cardiac massage
