Chapter 2 Troubleshooting Procedures
2 Getting Started Do one of these: •
To isolate or identify a problem, go to “Pre-Use Check” on page 2-2.
•
If a problem is known, go to “Rapid Problem/Solution Table” on page 2-3.
Do the repair analysis procedure (RAP) or a component replacement shown for the problem. To make sure the repair corrected the problem, do the Pre-Use Check. If troubleshooting procedures do not identify the problem, contact your distributor or local Hill-Rom representative.

Pre-Use Check Chapter 2: Troubleshooting Procedures
Pre-Use Check Do this before each use: 1. Connect the gas hose to a 50 psi oxygen source. 2. Connect the circuit to the controller.
3. Set the mode to CHFO, and select Higher. 4. Turn the selector ring on the handset to three dots.
Higher
5. Turn the master switch ON. 6. Occlude the patient opening of the handset. 7. Watch the pressure gauge. The average of pressure fluctuations should not be less than 15 and not more than 30 cm H2O. 8. Set the mode to CPEP.
Lower
9. Turn the CPEP flow adjuster counterclockwise to full flow. 10. With the selector ring at three, occlude the patient opening of the handset and monitor the manometer. Make sure there is a peak pressure occurrence of not less than 20 and not more than 30 cm H2O. 11. If the device is not within the parameters specified above, do not use the unit. Contact your distributor or local Hill-Rom representative to examine and repair the unit.

Chapter 3 Theory of Operation Introduction The MetaNeb™ System is indicated for the mobilization of secretions, lung expansion therapy, the treatment and prevention of pulmonary atelectasis, and also has the ability to provide supplemental oxygen when used with compressed oxygen gas. The MetaNeb™ System can administer three types of therapy modes: • Continuous Positive Expiratory Pressure (CPEP)-the system supplies medicated aerosol combined with continuous positive pressure to help hold open and expand the airways. • Continuous High Frequency Oscillation (CHFO)-this is a pneumatic form of chest physiotherapy that delivers medicated aerosol while oscillating the airways with continuous pulses of positive pressure. • Aerosol-this is for the delivery of aerosol only. There are three components to the system: • Controller • Air supply hose • Disposable single patient use (SPU) circuit
Controller The controller has an input air supply connection, a user interface, a master On/Off switch, an internal regulator, pneumatic control circuitry, an oscillatory valve, and an output connection point for the SPU circuit. • Input air supply connection-an air supply hose permits the controller to be connected directly to the facility’s compressed oxygen gas supply. • User interface-shows status information and permits the user to input commands that control the operation of the system. • Master On/Off switch-controls the flow of incoming oxygen gas into the controller; the flow is either off or on.

Controller Chapter 3: Theory of Operation
• Internal regulator-regulates the flow and pressure of the incoming oxygen gas into a range that can be used for both therapy modes and the nebulizer supply line. • Pneumatic control circuitry-determines the mode of operation and the flow level for CPEP mode. • Oscillatory valve-generates the pulses and determines the frequency used for CHFO therapy mode. • Output connection point (tri-connector port)-permits the disposable (SPU) to connect to the controller. The tri-connector port aligns the three supply lines (manometer feedback, nebulizer supply, and therapy) to the unit by means of the tri-filter and its mating tri-connector port. The three lines connect to the patient handset.

–
The manometer feedback line transmits pressure readings from the front end of the handset to the controller and manometer. The manometer shows the average peak pressure in the handset.
–
The nebulizer supply line connects to the nebulizer via a universal connection bushing, and the nebulizer connects directly to the handset. The air pressure and flow supplied by the nebulizer line causes the liquid contents of the nebulizer cup to be aerosolized directly into the handset.
–
The therapy line connects to the back of the handset at the jet port. The therapy gas flows into the jet and is concentrated to the opening of the internal venture in the handset body. The venture pulls in the aerosol from the nebulizer and the outside air through the entrainment ports on the back of the handset jet and amplifies the airflow to the front of the handset. The venture also regulates the amplification of the flow based on the back pressure in the front of the handset. The mouthpiece or other respiratory fitting acts as the interface to the patient and permits the therapy air and aerosol to get to the patient lungs.
