    Study Notes

    BIOPAC Calibration

    • BIOPAC equipment calibration is a two-step process.
    • The first step involves stabilizing the reference line with the transducer held vertically and immobile.
    • The second step calibrates amplitude and compensates for temperature and pressure by passing a known volume of air through the transducer using a syringe.
    • Five complete cycles with the syringe are performed, ending with the plunger fully retracted.
    • The final calibration screen should match the one depicted in Figure 21.
    • If an inverted deflection does not occur, change the transducer's orientation and repeat the calibration.
    • Calibration should be performed only once, regardless of the number of participants.

    Respiratory Function Recording

    • The participant must sit, look in the direction opposite the monitor, be relaxed, and have their eyes closed to minimize any external disturbance.
    • The participant places the nasal clip and secures the mouthpiece, and breathes normally through the apparatus for at least twenty seconds before starting the recording.
    • Participants always breathe through the adapter marked "Inlet."
    • The transducer must be held steady throughout the entire recording.
    • A respiratory cycle consists of inspiration and expiration.
    • Click the "Record 12" button and breathe normally for 3 cycles, then inhale as deeply as possible, hold your breath for a moment, and exhale forcefully and rapidly.
    • Then, exhale normally for 3 cycles.
    • Press the "Stop" button, then the "Find volume" button.
    • The recording should be similar to the one in Figure 24.
    • Data can be modified if the procedure was not strictly followed.

    Respiratory Cycle Measurement Recording

    • The subject should sit, looking in the direction opposite the monitor, relax, and with their eyes closed.
    • The subject should place the nasal clip and secure the mouth piece; and breathe normally through the device for at least 20 seconds before the recording starts.
    • Always breathe through the "Inlet" transducer end.
    • The transducer should be held upright throughout the recording.
    • A respiratory cycle consists of inspiration and expiration.

    Recording Procedure

    • Press the "Record 12" button.
    • Perform 5 normal breathing cycles.
    • Perform deep rapid breathing for 12–15 seconds.
    • Perform 5 normal breathing cycles.
    • Press the "Stop" button, then "Find volume" button.

    DVMM (Vmax) Recording Procedure

    • Click on the button "Redo 12" to measure DVMM (Vmax).
    • The subject should sit, looking in the direction opposite to the monitor, relax, and with their eyes closed.
    • The subject should place the nasal clip and secure the mouth piece; and breathe normally through the device for at least 20 seconds before the recording starts.
    • Always breathe through the "Inlet" transducer end.
    • The transducer should be held upright throughout the recording.

    DVMM (Vmax) Data Analysis

    • Use the selection tool to select an interval of 12 seconds in which the cycles are counted (approximately 15 cycles, monitor the Delta T value).
    • Mark the end of the selected area (click on the bottom part of the marker zone).
    • Use the selection tool to select each cycle within the 12-second interval.
    • If an incomplete cycle is found at the end, do not consider it.
    • Read the p-p values for each cycle.
