58 3100B HFOV WARNING Do not attempt to substitute a circuit configuration from any other instrument. Use of a non-3100A or a non-3100B circuit can result in injury to the patient or to the operator, and it may cause damage to the equipment. The Patient Circuit described in this manual is specifically designed for patient use with the Model 3100B HFOV. CAUTION When connecting the Patient Circuit, make certain that it is properly supported by the support arm as described in Chapter 6, Assembly and Installation. Failure to do so could result in inadvertent patient circuit disconnection due to oscillatory forces or could result in collection of humidifier condensate in the patient airway. CAUTION 4. Connect all color-coded Patient Circuit Control Lines and the clear Pressure Sense Line to their proper locations on the Patient Circuit as described in Chapter 6. Care should be taken not to crimp or perforate any of the control or sense lines (running to or from the Patient Circuit) during assembly or operation of the ventilator as this will cause malfunction of the Safety Alarms, Warning Alarms, Caution Alarms, and/or Pressure Limit controls. 5. Block off or obstruct the ET connection port on the Patient Circuit using the #1 rubber stopper accessory provided. 6. Turn on the Main Power Switch (the green LED on the Start/Stop pushbutton should be off). Some of the alarm LED's will be lit when power is first turned on. WARNING An audible alarm indicates the existence of a condition potentially harmful to the patient and should not go unattended. Failure to respond to alarms could result in injury, including death, to the patient and/or damage to the ventilator. CAUTION Ensure that the stopcock is closed prior to performing a Patient Circuit Calibration. If the Water Trap Stopcock is left open, Patient Circuit Calibration (39–43 cmH20) may not be achievable, and the deliverable Pa will be reduced. WARNING Ensure that the cooling fan at the rear of the driver enclosure is operational. 7. Calibrate the patient circuit to the system. (These instructions are also located on a label on the side of the Control Package). a. Turn on source gas pressure and establish Bias Flow at 20LPM. Be sure to read the flow at the center of the ball, looking level at the flow meter. b. Set Max Pa Alarm to 59 cmH2O. c. Set Mean Pressure Adjust control to Max (full CW). d. Push in and hold RESET while observing the Mean Pressure digital readout. It is normal for the Battery Low LED to light when the reset button is pressed. e. Adjust the Patient Circuit Calibration on the right side of the control package to achieve a Pa of 39 to 43 cm H2O. Do not overturn; if the specified pressure can not be achieved, locate the leak. f. Release the RESET button; the Battery Low LED should turn off. 767164–101 Rev. R
Operator’s Manual 59 CAUTION Do not overturn the Patient Circuit Calibration as this may cause damage to the device. When it is nearing its adjustment limit, it will reach a mechanical stop. CAUTION 8. Perform the Ventilator Performance Check “Off Patient Only” section. (These instructions are also located on a label on the top of the Control Package). a. Insert stopper in Patient Circuit “Y” and turn on both gas sources. b. Set BlAS FLOW for 30 LPM. c. Set Max Pa Alarm to 35 cmH2O. d. Rotate Mean pressure “ADJUST” knob to 12 o’clock position. e. Pressurize system by pressing and holding RESET, and ADJUST for a mean Pressure of 29-31 cmH2O. f. Set FREQUENCY to 6, % I-Time to 33, and press START/STOP to start the oscillator. g. Set POWER to 6.0. h. When a stable ∆P reading is obtained, verify that the ∆P and Pa readings are within the range specified for your corresponding altitude (see Figure 7.1). 9. Depress the START/STOP button to stop the oscillator. 10. With Mean Pressure Adjust and/or Bias Flow adjustment, achieve a mean airway pressure within 2 cmH2O of the desired level. Ensure that the Bias Flow is sufficient (see Chapter 9, Clinical Guidelines). 11. Verify the function of the thumb-wheel switches for “Set Max Pa” and “Set Min Pa” alarms by setting the Max thumb wheel just below the established Mean pressure, and by setting the Min thumb wheel just above the established Mean pressure. 12. Set these thumb-wheel alarm switches to their desired settings. This is generally 2–5 cmH20 above (Max thumb-wheel) and below (Min thumb wheel) the established Mean pressure. 13. With fingers and thumb(s), squeeze closed the 1/8" clear Pressure Sense tubing on the patient circuit to verify operation of the “Pa > 60 cmH2O” alarm. 14. Depress the RESET button until the “Pa < 5 cmH2O” LED is extinguished to reestablish the mean airway pressure. 15. Again, squeeze the pressure sense tubing on the patient circuit and observe the pressure at which the Mean Pressure display limits. 16. Position the ventilator for connection to the patient. Loosen the Position Lock control and adjust the angle of the Control Package for the best view and access relative to the patient. Retighten the Position Lock. 17. Set the desired % oxygen, Mean Pressure, and ∆P for the patient. ∆P will affect the Pa depending on ratio of Flow Rate/Pa. The lower the ratio, the stronger the effect. Fractional concentration of inspired oxygen should be verified with an oxygen monitor. Administration of excessive oxygen to a patient may be harmful. It is imperative that the prescribed gas mixture is delivered by the blending system. 767164–101 Rev. R
