Adult, infant and pediatric complete PFT

Complete your PFT for all ages

Our state-of-the-art and highly accurate yet easy-to-use PFT systems help diagnose pediatric, infant and adult lung diseases. We offer the full range of measurements—from lung volumes and diffusion capacity over body plethysmography, to impulse oscillometry and respiratory mechanics.

Vmax® Encore PFT system

The easy-to-use Vmax Encore PFT system collects data using real-time BTPS correction technology while complying with ATS/ERS and NLHEP standards.

MasterScreen™ PFT system

This PFT system offers single- and non-breath hold diffusion tests, rebreathing diffusion during lung volume maneuver and integrated dosimetry.

IOS spirometry

IOS spirometry has shown more sensitivity under resting conditions than spirometry in measuring small airway obstruction and post-bronchodilator effects.

MasterScreen™ PAED

MasterScreen PAED provides tidal flow-volume analysis, which studies show provides valuable information on how the baby's respiration is influenced.

MasterScreen™ BabyBody plethysmograph

The MasterScreen BabyBody plethysmograph helps test babies and premature infants using tidal breathing analysis and double-occlusion airway resistance.

Vmax® Autobox V62J and V62W system

The Vmax Autobox provides pressure-compensated flow technology in a spacious cabin, increasing test capabilities while decreasing test time.

MasterScreen™ Body plethysmograph

The MasterScreen Body plethysmograph is a spacious cabin with integrated sensors for box and mouth pressure and an easy-to-exchange, heated pneumotach.

APS Pro system

The APS Pro system allows single and multiple concentration protocols and computer-controlled nebulization with MasterScreen™ and Vmax® instruments.
