MasterScreen IOS
|
Why use IOS?
|
|
 | - Early detection of pathological impairments of the small airways.
|
|
| - Early diagnostic capabilities — successfully used by Respiratory Therapists in children as young as 4 years old.
|
|
| - Differentiate between peripheral and central airway disease
|
|
| - IOS is the perfect diagnostic tool for pediatric, geriatric, and neurologically compromised patients.
|
|
| - The automatic interpretation on the basis of a graphic lung model sets a new standard in diagnostic testing.
|
|
| - Determine the effects of medication in different sites of the lung.
|
|
| - Notebook capabilities as well as desktop.
|
|
| - IOS can be added to both your VMAX and Jaeger systems.
|
|
The MasterScreen IOS offers the determination of the respiratory impedance of the lung-thorax system including:
|
| |
|
| - Average values of respiratory impedance (resistance and reactance spectra)
|
|
| - Easy-to-understand graphic model-based interpretation including proximal and distal
|
|
| - Breath by breath analysis by differentiation of volume and flow interdependency of respiratory impedance
|
|
| - Slow and forced spirometry (inspiratory and expiratory flow-volume curve and Tiffeneau test)
|
Components:
|
|
| - Computer, printer and monitor, optionally on trolley or as portable notebook version
|
|
| |
|
| - IOS-head including loudspeaker generator, Y-adapter and terminating resistance
|
|
| - Reference impedance for calibration
|
|
| - Complete recording and analysis software including powerful data management features and calibration program
|
High-End Impulse Oscillometry
|
Early diagnosis and screening require an objective and sensitive method that is easily performed, and is independent of patient cooperation. MasterScreen IOS allows you to determine Respiratory Impedance without any technical expenditure and provides precise results for differential diagnosis, even outside hospital or practice.
The system is especially suited for use in paediatrics, geriatrics and occupational medicine because a few normal breaths are required for a complete test. The automatic interpretation on the basis of a graphic lung model sets a new standard in diagnosis.
|
| |
Precise Differentiation of Breathing Mechanics
|
MasterScreen IOS differentiates between proximal and distal components of the respiratory tract. This important feature allows early detection of pathological impairments of the so-called small airways. Additionally, the effect of drugs or medication in different sites of the lung can be determined.

Practical and Scientific - Convincing in Every Respect
|
The informative graphic display of the respiratory obstruction on the basis of a lung-thorax model is user-friendly. Researchers will be convinced by the comprehensive spectrum of analytically relevant parameters.
The relevant recording parameters will be output graphically and numerically, so that the quality of the test can be assessed already during recording. Artefacts will be detected immediately. And last but not least, MasterScreen IOS is fast. Within less than one minute, the system provides exact and reliable results.
|
| |
Flexible and Portable.
|
For outpatient application MasterScreen IOS can also be used in combination with a notebook computer. Installation only takes a few minutes and respiratory impedance can be measured wherever and whenever you want.
|
| |
Most important options include:
|
| |
|
| - APS, the aerosol provocation system
|
|
| - The paediatric version with a full face mask
|
|
| - Rhinomanometry by passive anterior measurement
|
|
| - Bedside option to allow measurements with patients in bed
|
The Principle of Impulse Oscillometry is Easy and is Safe.
|
A characteristic feature of Impulse Oscillometry is that pulmonary impedance is not derived from the respiratory signals but from the pressure-flow relationship of artificial impulse-shaped test signals which are produced by an external generator. These artificial signals are superimposed on the respiratory tidal breathing waveform of the patient in the Y-adapter while the patient simply inhales ambient air via mouthpiece, pneumotach and terminating resistance (<0.1 kPa/l/s). The advantage of artificial test signals is the incomparably higher frequency contents with a relatively high consistency as far as frequency range and amplitude are concerned, so that a thorough differentiation of pulmonary function is possible.
