GSI Allegro

The GSI Allegro™ is a handheld screening tympanometer ready for any testing environment that requires tympanometry and ipsilateral reflexes. The Allegro offers a four button navigation that allows for quick and reliable testing. Automatic measurements of the middle ear status are completed in seconds using the device’s configurable test settings. The Allegro includes a charging cradle, thermal printer, and carrying case.

• Quickly obtain a seal for tympanometry. Once a seal is obtained, testing begins immediately.
• Four key tymp measurements include peak pressure, ear canal volume, tympanometric width, and admittance at peak.
• Global settings such as test sequence and test prompts may be defined by the user.
• The Allegro is designed with portability in mind. The device is lightweight and perfect for any testing environment.
• Four button navigation simplifies the testing procedures for a fast paced testing environment.
• Test multiple patients and manage the data at your convenience. The Allegro can store up to 32 patient testresults to be analyzed and managed at a different time.

TYMPANOMETRYInstrument Type: Meatus compensated tympanometerAnalysis Performed: Admittance peak level (in ml); Peak pressure of same; Gradient (in daPa); Ear canal volume (ECV) at 200 daPaProbe Tone Levels and Accuracy: 226 Hz +/-2%; 85 dB SPL +/-2 dB over range 0.2 ml to 5 mlPressure Levels and Accuracy: +200 daPa to -400 daPa +/-10 daPa or +/-10% (whichever is larger) over rangeEar Volume Measurement Range and Accuracy: 0.2 ml to 5 ml +/-0.1 ml or +/-5% (whichever is larger) over entire rangeSweep Speed: Typically 200 daPa/sec; dependent on ear/cavity volumePressure Limits (Safety Cut Out): +600 to -800 daPa

REFLEX MEASUREMENTSMeasurement Modes: IpsilateralReflex Tone Levels and Accuracy: 500 Hz, 1 kHz, 2 kHz, 4 kHz(+/-2%); Configurable over range 70 dB to 100 dBHL (4 kHz restricted to 95 dBHL) +/-3 dB, referenced to 2 ml calibration volume; Compensates for measuredear volumeReflex Detection Threshold and Accuracy: 0.01 ml to 0.5 ml +/-0.01 ml configurable in 0.01 ml stepsReflex Analysis: Reflex present/absent at each level tested; maximum amplitude of each reflex (seen on printed report & computer report); pressure at which reflex was performedPressure Used for Reflex Measurement: Pressure at Tympanogram peak, or 0 daPaReflex Tone Duration: 0.6 seconds

DATA MANAGEMENTNumber of Records Stored in Patient Database: 32 patientsData Stored: Patient initials, tympanogram, reflex graphs, analysis, time/date,and test parameters
