Ventilation Modes

The EO-150 offers a variety of pressure and volume ventilation modes, including:

  • (A)VCV: Volume Assisted Controlled Ventilation (with expiration valve)
  •  (A)PCV: Pressure Assisted/Controlled Ventilation (with expiration valve)
  •  PSV: Pressure Support Ventilation (with expiration valve)
  •  MPV: Mouthpiece Volume Ventilation
  • MPP: Mouthpiece Pressure Ventilation
  • PSV VT: Pressure Support Ventilation Volume regulated (with expiratory valve)
  • V-SIMV: Volume Synchronized Intermittent Mandatory Ventilation (with expiratory Valve)
  • P-SIMV: Pressure Synchronized Intermittent Mandatory Ventilation (with expiratory valve)
  • CPAP: Continuous Positive Airway Pressure (with leak)
  • S(T): Spontaneous Timed (with leak) 
  • PAC: Pressure Assisted/Controlled (with leak)
  • VTS: Volume Target Spontaneous (with leak)
  • C-FLOW: Continuous Flow

C-FLOW mode is a humidified therapy that requires a heated humidifier.

Connections

  • Connect the short circuit to the inspiratory port of the ventilator.
  • Connect the heat circuit, temperature probes, and electric adapter.
  • Connect the nasal cannula and use the leak adapter included in the starter kit.
  • Select the appropriate setting on the humidifier.
  • Fit the nasal cannula to the patient.

Configuration

Follow these steps on the EO-150's display to activate and set the C-FLOW mode:

  • Select CLINICAL on the main menu.
  • Navigate to the CONFIG tab.
  • Choose Circuit type: Leak.
  • Under Ventilation, select Flow type and then C-FLOW mode.
  • On the SETTINGS tab, set the parameters for the C-FLOW mode.
  • For adult patients, the flow can be set from 10 to 60 L/min.
  • For pediatric patients, the flow can be set from 2 to 25 L/min.
  • Ensure that the oxygen flow does not exceed the set flow rate.

Mouthpiece Ventilation (MPV) can be set up in two primary modes: Pressure Control (MPP) or Volume Control (MPV). Successful adaptation and patient comfort rely on fine-tuning the trigger settings, which may include adjusting the Bias Flow and Inspiratory Trigger (I.Trig).

Key Considerations for Patient Comfort and Adaptation

  • Trigger Adjustment: It is possible to adjust the patient's comfort by playing with both the trigger mechanisms: Bias Flow (+) and I. Trig (-).
  • Bias Flow: The Bias Flow can even be switched OFF.
  • Alarms: It is possible to switch off the disconnection alarm and the Respiratory Rate (RR) monitoring if required by the clinical context. 
Setting Positive Trigger (± 0.2 mbar) Negative Trigger (± 0.2 mbar)
AUTO +0.4 mbar -0.7 mbar
1 +0.3 mbar -0.4 mbar
2 +0.4 mbar -0.7 mbar
3 +0.6 mbar -1.2 mbar
4 +0.8 mbar -1.8 mbar
5 +1.0 mbar -2.4 mbar

Note: Lower I. Trig settings (e.g., 1) require less effort (less negative pressure) from the patient to initiate a breath, potentially increasing comfort.


MPP in Pressure Control

This mode delivers a breath until a preset pressure is reached.

Setting Value Notes
Mode Mouthpiece Ventilation in Pressure (MPP) This is the specific mode name for Pressure-controlled MPP.
Respiratory Rate TURN OFF / 5-60 (Adult) / 5-80 (Ped) When turned off, it allows the patient to initiate all breaths.
Control Pressure 5-49 cmH2O Sets the target inspiratory pressure (IPAP) level.
Bias Flow TURN OFF / 1-20 LPM Allows adjustment to facilitate sensitivity to the patient's trigger.
I Trigger AUTO / 1-5 Allows you to set an appropriate sensitivity (e.g., AUTO or a low number such as 1 to facilitate patient triggering).
Slope 1-5 Adjusts the speed at which the pressure reaches the set control level (1 = Fast, 5 = Slow).
I Time 0,3-2,5 s Allows adjustment of inspiratory time if the frequency is adjusted.


MPV in Volume Control (MPV-V)

This mode delivers a preset volume with each patient-initiated breath.

Setting Value Notes
Mode Mouthpiece Ventilation in Volume This is the specific mode name for Volume-controlled MPV.
Respiratory Rate TURN OFF / 5-60 (Adult) / 5-80 (Ped) When turned off, it allows the patient to initiate all breaths.
Tidal Volume (TV) 100-2500 ml (Adult)/ 100-600 ml (Ped) The target tidal volume should be administered with each breath initiated by the patient..
Bias Flow TURN OFF / 1-20 LPM Allows adjustment to facilitate sensitivity to the patient's trigger.
I Trigger AUTO / 1-5 Allows you to set an appropriate sensitivity (e.g., AUTO or a low number such as 1 to facilitate patient triggering).
Slope Square, descending Select the flow pattern based on patient comfort.
I Time 0,3-2,5 s Allows adjustment of inspiratory time if the frequency is adjusted.
