Vyntus APS

For accurate and safe bronchial challenge testing
Vyntus APS is an Aerosol Provocation System. Up-to-date and sophisticated electronics and mechanics allow for optimal use of its nebulization technology with precise dosing. For the observation measurements Vyntus APS combines with the Vyntus PNEUMO and/ or the Vyntus IOS in one system.

APS nebulizer system integrates into Vyaire MasterScreen™ and Vyntus™ instruments – Spirometry, IOS Impulse Oscillometry, Rocc and BODY Plethysmography. The nebulizer system is powered by SentrySuite™ software and is able to test a broad age range: from 4 years to adult. Choose between single and multiple concentration testing.

Everything you demand from a provocation system

  • Single and multiple concentration bronchial provocation testing
  • The two modes of administration, pulse or continuous nebulization allow for a broad age range to be tested
  • Time and volume-controlled process guarantees highest drug efficiency
  • Computer-controlled nebulization guarantees the amount of drug inhaled is reproducible
  • Timer functionality monitors exposure times
  • Automated calculation of PD and PC based on FEV1, R5, Fres, sRaw, sGaw, etc.
  • Standard protocols delivered with each system, with the ability to customize and make your own
  • Real-time visualization of dose administration and breathing patterns
  • The APS uses a high efficiency filter to eliminate the risk of cross-contamination
  • Intelligent SentrySuite™ software guides the user through the entire measurement process – protocol customization and improved observation module

Choose out of two modes of administration

Choose out of two modes of administration, i.e. pulse or continuous nebulization. The process is time and volume controlled so that the highest drug efficiency is guaranteed. After each provocation step the software calculates the actual dose that has been administered. When the pre-set dose has been achieved the compressor automatically in control during nebulization with real-time visualization of dose administration and breathing patterns during nebulization.

Safe and accurate testing
The build-in intelligence of the observation module ensures patient safety whilst achieving accurate provocation thresholds (automated PD, PC calculation). After the initial baseline measurement to exclude a contra-indication, the software monitors the patient’s response to each provocation step. It either automatically progresses to the next provocation step or flags that the pre-set provocation level has been achieved.
