COVIDIEN PURITAN BENNETT 980 (01) PDF Document

The COVIDIEN PURITAN BENNETT 980 ventilator is equipped with an on-screen help system called tooltips. If a tooltip is available for an item on the screen, a glowing blue outline will appear around it.

To access tooltips:

1. Touch the item in question for at least 0.5 seconds, or drag the help icon (the question mark icon at the lower right of the screen) to the item. A tooltip with a short description will appear.

2. Touch “more” on the dialog to see an expanded description.

3. Touch “close” to close the dialog, or it will fade away after 5 seconds.

Note:

Dragging the help icon causes the tooltip to display in its unexpanded state.

Dragging the help icon and pausing causes a tooltip to display. Continuing to drag to another item will dismiss the last tooltip and display a new one.

If the graphical user interface (GUI) display becomes blank, unreadable, or unresponsive, first assess the patient to confirm ventilation is in progress. Examine the status display on top of the breath delivery unit (BDU) to confirm ventilator function. If your clinical judgment determines the patient’s status is satisfactory and ventilation is continuing as set, follow the steps for the specific condition below.

1. Unresponsive screen with display still visible and waveforms active:

If the GUI is unresponsive, inaccurate, or has unintended responses, reset the touch screen.

To reset the touch screen:

1. Touch the display lock key on the GUI bezel to lock the screen. A locked padlock icon will appear.

2. Touch the display lock key again. A progress bar will appear below the padlock icon, after which it will unlock, indicating a successful reset.

Alternatively, ensure no patient is connected and power cycle the ventilator.

Note: Do not touch the screen during the unlock period.

2. Momentary Blank GUI Screen / GUI Transient Reset:

If the GUI resets spontaneously, the status display will show a count-down timer. Assess the patient and wait for the GUI reset to finish (approximately 30 seconds).

3. Blank GUI Screen / GUI Failure:

An error message will appear on the status display. If this occurs, confirm that ventilation continues as set. Provide alternate ventilatory support or transfer the patient to another ventilator according to your institution’s protocols as soon as appropriate. The ventilator should be serviced before being used on patients again.

If, in your clinical judgement, the patient’s status is unsatisfactory, consider patient transfer to another ventilator or provide an alternate source of ventilation in accordance with your institution’s protocols. The ventilator should be replaced as soon as possible and repaired by qualified service personnel.

To set up the ventilator for a new patient, follow these steps:

1. Connect the ventilator to the electrical and gas supplies.

2. Connect the appropriate patient circuit (adult/pediatric or neonatal) to the ventilator.

3. Turn the ventilator on using the power switch.

4. Before ventilating, run a Short Self Test (SST) to calculate the compliance and resistance with all items included in the patient circuit.

To ventilate a new patient:

1. Touch New Patient on the GUI screen. The New Patient settings screen will appear.

2. Enter the patient’s Predicted Body Weight (PBW) or gender and height.

3. If the default ventilator settings are appropriate, touch Start to confirm. Otherwise, touch a ventilator setting and turn the knob to adjust the parameter. Continue this for all necessary parameters.

4. Touch Accept or Accept ALL to confirm the changes.

5. Connect the circuit to the patient’s airway to start ventilation.

A Short Self Test (SST) must be run before ventilating a new patient, when changing the patient circuit or its components, or when adding/removing accessories. Always disconnect the patient before running SST.

Required Equipment:

• Proposed patient circuit for ventilation

• Accessories (e.g., water traps)

• Exhalation filter and condensate vial

• Humidifier, if applicable

• A number 1 stopper to block the patient wye

• Two gas sources (air and oxygen) connected to the ventilator at a pressure between 241.3 kPa and 599.8 kPa (35 psi and 87 psi)

To run SST:

1. Ensure a patient is not connected to the ventilator.

2. Ensure the breathing circuit wye is not attached to a test lung or covered.

3. Turn the ventilator on. The ventilator runs a Power On Self Test (POST). Ensure it is operating on full AC power.

4. Wait at least 15 minutes for the ventilator to warm up.

5. At the ventilator startup screen, touch SST or the configure icon (wrench).

6. Connect the patient circuit, filters, condensate vial, and all accessories. Ensure the patient wye is not blocked.

7. Touch Run All SST to perform all tests or Run Leak Test for only the leak test.

8. Touch Accept to continue or Cancel to go back.

9. After accepting, touch the Circuit Type button corresponding to the patient circuit type (adult, pediatric, or neonatal).

10. Touch the Humidification Type button corresponding to the type used. If a humidifier is used, touch Humidification Volume and enter the correct volume.

11. Touch Accept to start SST.

12. Follow the on-screen prompts. Certain tests require operator intervention.

13. After each test, the ventilator displays the results. If a test fails, you can choose to repeat the test or perform the next one.

When the SST is complete, the status screen displays the individual test results. The overall outcomes are as follows:

WARNING: Overriding an Alert in SST may result in ventilator performance outside of the stated specification for accuracy. Choose to override the Alert status and authorize ventilation only when absolutely certain this cannot create a patient hazard or add to risks arising from other hazards.

WARNING: One primary battery must be installed at all times in the BDU’s primary battery slot for proper ventilator operation. The ventilator will not complete the startup process without the primary battery installed.

The ventilator uses primary and optional extended batteries. The primary battery is in the rearward receptacle on the right side of the BDU, and the extended battery is in the forward receptacle.

To install or replace the primary battery in the BDU or compressor:

1. Check the battery’s charge level by pressing the charge level button on the battery. Five green LEDs indicate ≥90% capacity. A red LED indicates a fault.

2. If the charge is sufficient, orient the battery as shown in the manual. The receptacle towards the rear houses the primary battery.

3. The primary battery is fastened with a thumbscrew. Loosen the thumbscrew approximately four to five turns to allow installation.

4. Insert the battery into its receptacle until it clicks. It will only fit one way.

5. Tighten the thumbscrew to secure the battery.

To remove the primary battery, loosen the thumbscrew and slide the battery ejector to the left to eject it.

To install or remove an extended battery in either the BDU or compressor:

1. Properly orient the battery.

2. Push the battery into the forward receptacle until it clicks, indicating it is latched.

To remove the extended battery, slide the battery ejector to the left. The battery will eject. There is no thumbscrew for extended batteries.

A manual purge may be performed any time the sensor lines contain excessive condensation, moisture, or secretions.

To perform a manual purge:

1. Touch the Configure icon in the constant access icons area of the GUI.

2. Touch the Options tab. A screen appears containing the Installed Options and Prox tabs.

3. Touch the Prox tab. The Prox Setup screen appears.

4. Touch START that appears next to the text “Prox Manual Purge: To begin touch the Start button”. During the purge, a message appears in the GUI prompt area stating the purge process is being performed.

External surfaces of the GUI, BDU, and compressor base should be cleaned periodically.

2. With your thumb in the plastic exhalation port and four fingers under the EVQ, pull it down until it snaps out. To avoid damaging the flow sensor element, do not insert fingers into the center port.

3. Remove and discard the disposable components: exhalation valve diaphragm, exhalation filter seal, and pressure sensor filter.

Disinfection:

WARNING: Do not steam autoclave the EVQ or sterilize with ethylene oxide gas.

1. Presoak the EVQ in an enzymatic solution to break down any bio-film. Follow the manufacturer’s instructions for duration.

2. Rinse in clean, deionized water.

3. Prepare the chemical disinfectant according to the manufacturer’s instructions. Use only approved disinfectants.

4. Immerse the EVQ in the disinfectant solution, oriented as shown in the manual, and rotate to remove trapped air bubbles. Keep immersed for the minimum time specified by the manufacturer.

5. At the end of the immersion period, remove and drain all disinfectant completely.

Rinsing:

1. Rinse the EVQ using clean, deionized water in the same manner as the disinfection step.

2. Drain and repeat rinsing three times with clean, deionized water.

3. After rinsing, immerse in a clean isopropyl alcohol bath for approximately 15 seconds. Slowly agitate and rotate to empty air pockets.

Drying:

1. Dry in a low temperature warm air cabinet designed for this purpose, with temperature not exceeding 60°C (140°F).

Inspection:

After disinfection, inspect the plastic body, diaphragm sealing surface, filter grommet, and seal groove for any damage, degradation, or contamination. Inspect electrical contacts and clean with a soft cloth if necessary. Inspect the hot film wire and thermistor for damage; do not attempt to clean them. If rinsing is unsuccessful or they are damaged, replace the EVQ.

You will need an EVQ Reprocessing Kit which contains a new diaphragm, pressure sensor filter, and exhalation filter seal.

EVQ Reassembly:

1. After drying the EVQ, take the new pressure sensor filter from the kit. Install its large diameter into the filter grommet with a twisting motion until it is flush with the plastic valve body. The narrow end should face out.

2. Take the new exhalation filter seal from the kit. Turn the EVQ so its bottom is facing up.

3. Install the seal into the exhalation flow sensor, ensuring it fits completely within the recess and sits flat.

4. Remove the new diaphragm from the kit and install it. Ensure the diaphragm bead is located in the EVQ’s groove.

5. Carefully inspect component placement and the complete assembly.

To install the EVQ into the ventilator:

1. With the exhalation filter door open, insert the assembly directly under the exhalation valve and push straight up until it snaps into place.

2. Install the exhalation filter by sliding it onto the tracks in the door, orienting the filter’s from patient port through the hole in the door.

3. Close the exhalation filter door and lower the exhalation filter latch.

4. Calibrate the flow sensor.
