New GSI Suite V1.1
GSI TympStar
Overview
The GSI TympStar sets the standard for clinical middle-ear testing... A standard that had been established by its predecessor, the GSI 33. The sophistication, functionality and flexibility of the GSI TympStar provides unparalleled testing capabilities.
The GSI TympStar Version 1 provides four different test modes: tympanometry, reflex threshold, reflex decay, and Eustachian tube function testing.
Move up to the Version 2 if you are interested in accurately testing newborns and differential diagnosis of middle ear problems using multiple component and multi-frequency tympanometry.
The GSI TympStar is now EMR compatible with GSI Suite V1.1.
The GSI TympStar's ergonomically designed control panel allows you to select a test protocol by simply pressing a button, and its large screen makes for easy viewing of test parameters, possible alternatives and test results. The high-speed printer generates reports in concise graphical or tabular formats. GSI TympStar options include a VGA monitor for displaying test results, an external printer that produces test results in a larger format, and a keyboard for entering patient information.
The GSI TympStar also offers several options for managing and archiving data including internal memory for 26 tests and a standard RS232 for data exchange.

Features
|
Tympanometry (V1 and V2) The GSI TympStar offers automatic or manual 226 Hz tympanometry in a diagnostic or screening mode. Sensitivity scales are automatically determined based on the peak amplitude of the tympanogram. The built-in screen can simultaneously display up to three tests, helping you to determine the presence or absence of a peak on a low-amplitude tympanogram. |
Reflex-Decay Testing (V1 and V2) The GSI TympStar's screen clearly displays reflex decay time in seconds, as well as marks the five and ten second interval points. |

Two-Component Tympanometry (V2 only) Version 2 offers additional tympanometric capacity to test Admittance (Y), Susceptance (B) and Conductance (G) at 226, 678 and 1,000 Hz probe tones. This helps you quickly and clearly determine where, along the ossicular chain, problems in the middle ear are occurring in patients of all ages. |
Eustachian Tube Function (ETF) Testing (V1 and V2) Two separate test modes are available, one for testing ETF with an intact tympanic membrane (TM) and one for testing ETF in a perforated TM. The ETF mode for an intact TM eliminates the need to instruct a patient to perform a Toynbee or Valsalva test. |

|
Acoustic Reflex Threshold Testing (V1 and V2) Acoustic reflex testing with the GSI TympStar allows you to automatically or manually time the tone presentation. Multiple stimuli and intensities are available to determine the threshold level for the acoustic reflex. Automatic threshold determination and threshold marking are available. |
Multiple Frequency Tympanometry (V2 only) Multiple-frequency tympanometry allows you to easily determine the middle-ear resonance frequency. Normal middle ears exhibit a resonance frequency of between 800 and 1200 Hz. A middle ear with otosclerosis would be above 1200 Hz, and a disarticulated ossicular chain would be below 800 Hz. When used in pre and post-operative test comparisons, this can give you quantitative proof of a patient's improvement. |
