e700 Ventilation Modes

The e700 transport ventilator has 13 ventilation modes:

  • Manual Ventilation

  • Controlled Mandatory Ventilation (CMV),

  • CMV with Pressure Control Ventilation (PCV)

  • Assist Control Ventilation (A/C V)

  • A/C V with PCV

  • Synchronized Intermittent Mandatory Ventilation (SIMV)

  • SIMV with Pressure Support Ventilation(PSV) (P-SIMV)

  • BiLevel Pressure Ventilation (BiLVL)

  • BiLVL with PSV

  • CPAP

  • CPAP with PSV

  • Mask CPR

  • Intubated CPR

1. Assist/Control Volume Ventilation (A/C V)

Assist Control Ventilation (A/C V) – Ventilator will deliver Mechanical Ventilation at the set Tidal Volume (Vt) and Rate (BPM). If the patient makes a spontaneous effort and initiates the start of the ventilation cycle the ventilations then become Patient Triggered however, the Ventilator will maintain the selected ventilation parameters.

2. Assist/Control Pressure Ventilation (A/C P)

In the pressure Controlled Ventilation (PCV) setting the ventilator generates the preset pressure during a preset inspiratory time and at a preset ventilation rate (as selected by the operator). There is no Tidal Volume selection in the PCV mode. The pressure is constant during the inspiratory time and the flow is decelerating.

3. Controlled Mandatory Ventilation (CMV)

In the A/C V mode if the Trigger (Trig) is turned off (“–“) the ventilator will deliver mandatory ventilation regardless of the patient’s inspiratory effort.

4. Synchronized Intermittent Mandatory Ventilation – (SIMV)

The SIMV mode allows the patient to breath spontaneously. If assistance is needed the vent will assist. If NO patient effort during trigger window – Ventilator will initiate Mandatory Ventilation.

5. SIMV with Pressure Support Ventilation (P-SIMV)

Pressure Support Ventilation (PSV) is a spontaneous mode of ventilation where the patient initiates every breath and the ventilator delivers inspiratory support to the selected pressure value.

In the P-SIMV mode, the ventilator will assist the spontaneously ventilated patient with pressure cycled breaths at their own respiratory rate and tidal volume.

6. Constant Positive Airway Pressure (CPAP)

In CPAP mode, the ventilator will deliver a continuous flow rate to generate a continuous positive pressure in the airway. The ventilator uses the control valve to maintain the CPAP level.

Note: CPAP is pre-set with 20-second APNEA backup – settings for Rate BPM, Tidal Volume (Vt), I:E ratio and Minute Volume (Mv) location is set at the bottom of the screen. The default settings can be adjusted by the operator.

7. CPAP with Pressure Support Ventilation (CPAP +PSV)

CPAP + PSV is equivalent to BiPAP and provides positive airway pressure through both the inspiratory and expiratory phases of the breathing cycle but at two different levels. This reduces the work of breathing for the patient as the lower expiratory pressure allows
for easier exhalation while the higher inspiratory pressure assists in inhalation.

CPAP + PSV is equivalent in effect to BiPAP.

To create BiPAP with the e700 ventilator we utilize the CPAP setting to generate the lower, expiratory, pressure and the Pressure Support Ventilation setting to generate the higher, inspiratory pressure.

The peak inspiratory pressure is the CPAP pressure + the PSV pressure e.g.: 5 cm H2O of CPAP + 10 cm H2O of PSV = a 15cm H2O peak inspiratory pressure.

Note: CPAP is pre-set with 20 second APNEA backup – settings for Rate BPM, Tidal Volume (Vt), I:E ratio, and Minute Volume (Mv) location is set at the bottom of the screen. The default settings can be adjusted by the operator.

8. Biphasic Pressure Ventilation (BiLVL)

Note: Biphasic is NOT BiPAP – it is similar to SIMV with pressure control (P-SIMV) and optional Pressure Support Ventilation.

9. CPR Modes

The CPR Mode consists of timed chest compression audible prompts coupled with automatically delivered breaths for both intubated and mask ventilated patients. The screen displays a visual animated display to guide the health care provider while performing CPR. Oxygen is delivered automatically at 100%.

Use of a Chest Compression Device or CPR with no Pictogram or Sound

Note: When using a chest compression device with the e700, the set CPR modes with pictogram and sound will be difficult to synchronize with the device.

To use a chest compression device simply….

  • Set the e700 to A/C V mode

  • Turn off the PEEP

  • Turn off the Trigger

  • Set Pressure Max (Pmax) at 60 cm H2O

  1. Appropriate size of patient is already selected – pre-set default in A/CV start up​ mode -or operator can select the proper preferred Title Volume and Rate

  2. Operator has the option to adjust other parameters based on local protocol.

A/C V settings with Trigger turned off, “0” PEEP and Pmax set to 60 cm H2O.
A/C V settings with Trigger turned off, “0” PEEP and Pmax set to 60 cm H2O.
