Operator’s Manual Addendum

Introduction This addendum describes enhancements to the 840 Ventilator System and changes to the 840 Ventilator System Operator’s and Technical Reference Manual part number 4-075609-00 up to and including Revision G, and part number 4-07008800 up to and including Revision F. NOTE: If you have 840 Ventilator System Operator’s and Technical Reference Manual part number 4-075609-00 Revision F, your manual has been updated with the information contained in this addendum except for any references to PAV™*+ option, PA breath type, the Flow-Volume loop plot information starting on page 21, and the RS-232 command update starting on page 37. If your manual is Revision G, it has been updated with the information contained in this addendum except for the Flow-Volume loop plot information starting on page 21 and the RS-232 command update starting on page 37. If you have 840 Ventilator System Operator’s and Technical Reference Manual part number 4-070088-00 Revision E or later, your manual has been updated with the information contained in this addendum except for the Flow-Volume loop plot information starting on page 21 and the RS-232 command update starting on page 37. Updates to the manual include: •

The patient circuit type specified during short self test (SST) determines default settings and available ranges for ventilator operation.

•

Certain recommended ranges can be overridden. Touching the OK button allows operation outside the recommended setting range.

•

The humidification type can be changed after running SST without adversely affecting breath delivery or spirometry, and humidifier volume can be entered for non-HME humidifiers during or following SST.

•

A prompt has been added at the start of the SST compliance test to allow the operator to check for the presence of water in the humidifier.

•

A reminder arrow now flashes at the Ventilator Startup screen to prompt the operator to consider previous settings.

•

Display of data on the upper GUI screen is larger for improved visibility at a distance.

Operator’s Manual Addendum

•

Alarm Silence in Progress and 100% O2/CAL in Progress indicators (when active) and the CANCEL buttons for them are displayed on the lower GUI screen.

•

The main settings (buttons displayed at the top of the lower screen) can be set individually or in a batch to allow quick setup.

•

Drop-down menus of available selections have been added for mode, mandatory type, spontaneous type, trigger type, apnea mandatory type, and graphics plot setup.

•

The lower screen displays monitored settings if you select or change the settings that affect them:  Selecting or changing the volume setting displays the current volume per weight ratio (VT/IBW or VT SUPP/IBW).  Selecting or changing the respiratory rate or volume setting displays the set minute volume (VE SET).

•

Expiratory sensitivity (ESENS) is now a primary setting that appears at the top of the lower screen. ESENS can be set as high as 80% for leak management.

•

The alarm setting bars on the Alarm Setup screen display the recent range of the corresponding patient data.

•

Circuit disconnect and patient data alarms no longer reset an active alarm silence.

•

Oxygen sensor calibration (100% O2 CAL) can be canceled.

•

An automatic expiratory or inspiratory pause maneuver can be canceled by touching the CANCEL button on the lower GUI display.

•

If the ventilator enters idle mode or an occlusion status cycling (OSC) state when NeoMode is active, the ventilator delivers 40% O2 if available.

•

Peak Circuit Pressure (PPEAK) shows the peak inspiratory pressure, and is updated at the end of each inspiration. Previously, this number represented the peak pressure for the whole breath.

•

Mean Circuit Pressure (PMEAN) indicates the average circuit pressure over all breaths for the previous 1-minute interval.

•

The O2 sensor alarm is no longer a DEVICE ALERT alarm.

•

Various alarm parameters have been changed to reduce the occurrence of nuisance alarms.

Operator’s Manual Addendum

Update to patient circuit ranges This section updates Operator’s Manual section 2.3. Warning When using a Fisher & Paykel™* humidifier with the 840 Ventilator, use the Fisher & Paykel™* model 210 or 250 humidifier chamber for adult patients and the model 220 or 290 humidifier chamber for pediatric patients. Other Fisher & Paykel™* humidifier chambers can cause water to splash into the patient circuit during circuit disconnects and high peak flow rate conditions.

Patient circuit type selection Table 1 shows IBW values and patient circuit types. The “Allowed but not recommended” ranges require an override. Table 1. Patient circuit and IBW values Recommendation Recommended

Ideal body weight (IBW) in kg (lb) Neonatal: 0.5-7.0 kg (1.1-15 lb) Pediatric: 7.0-24 kg (15-53 lb) Adult: 25-150 kg (55-330 lb)

Allowed but not recommended

Neonatal: Not applicable. Pediatric: 3.5-6.5 kg (7.7-14.3 lb), and 25-35 kg (55-77 lb) Adult: 7-24 kg (15-53 lb)

Warning Recommended ranges exist to ensure patient safety. Only those with expertise to judge the appropriate circumstances should override the recommended ranges.

Operator’s Manual Addendum

Update to short self test (SST) and humidification type This section updates Operator’s Manual sections 3 and 4.8.

SST setup For optimum inspiratory volume and spirometry accuracy, SST asks you to specify the humidification type: Heated exp tube, Non-heated exp tube, or HME (HME = heat-moisture exchanger). For non-HME humidifiers, you can touch the HUMIDIFIER VOLUME button, then turn the knob to select the dry humidifier volume (the humidifier’s specified volume, not compressible volume). The HUMIDIFIER VOLUME button is not visible when HME is selected.

SST compliance calibration For a humidification type of Heated exp tube or Non-heated exp tube, the ventilator prompts you to indicate if there is water (YES or NO) in the humidifier.

Changing humidification type after SST For optimum spirometry accuracy, humidification type and volume (for non-HME humidifiers) can now be changed after running SST. Follow these steps to select the humidification type and set its volume: 1.

Touch the OTHER SCREENS button, then touch the MORE SETTINGS button.

2.

Touch the HUMIDIFICATION TYPE button, then turn the knob to select the new value (Heated exp tube, Non-heated exp tube, or HME).

3.

For non-HME humidifiers, touch the HUMIDIFIER VOLUME button, then turn the knob to select the dry humidifier volume. (The HUMIDIFIER VOLUME button is not visible when HME is selected.)

4.

Review the proposed settings, then press ACCEPT to apply the new settings.

Operator’s Manual Addendum

Update to Ventilator Startup screen This section updates Operator’s Manual section 4.1. The Ventilator Startup screen (Figure 1 below) has changed: •

Expiratory sensitivity (ESENS) is now a primary setting and appears at the top of the lower GUI screen.

•

The startup screen includes flashing reminder arrow (next to the SAME PATIENT button) that prompts the user to consider previous settings.

•

During and after Ventilator Startup, drop-down menus of available selections are displayed for vent type, mode, mandatory type, spontaneous type, trigger type, and apnea mandatory type.

•

Once Ventilator Startup is complete, the volume per weight ratio is displayed when the volume setting is selected or changed. Volume = tidal volume (VT) when breath type is VC, target volume (VT) when breath type is VC+, target support volume (VT SUPP) when breath type is VS.

•

VE is no longer displayed in the Ventilator Startup screen.

•

For additional changes to Ventilator Startup screen, see “Ventilation Type – INVASIVE/NIV” on page 26.

Updated ranges for settings, alarms, and data This section updates Operator’s Manual section 4.9 and Appendix A.6, and includes only changes to ventilator settings or alarms. Ventilators equipped with the NeoMode option can select all ranges (neonatal, pediatric, or adult). Only pediatric and adult ranges are available to ventilators without the NeoMode option. Some settings have recommended limits that can be overridden. When a proposed setting exceeds the recommended limits, the ventilator sounds a tone and asks you to confirm that you want to override the recommended range.
