BodyBox PFS plethysmograph

Complete Body Plethysmograph Solutions

Contact a Sales Rep

The Body Plethysmograph (Bodybox) is considered the gold standard for the measurement of Functional Residual Capacity (FRC) and Lung sub-divisions, with the ability to measure both ventilated and non-ventilated lung areas. This then coupled to Airways Resistance and Spirometry with a wide range of Diffusion options and gas dilution lung volumes, provides a comprehensive testing station.

  • Complete basic spirometry measurement, with Forced Vital Capacity, Slow Vital Capacity, Maximum Voluntary Ventilation and Minute Tidal Ventilation including bronchial provocation testing software.
  • Thoracic Gas Volume and Lung sub-divisions (FRC-pleth, VC, IC, ERV, RV and TLC) using plethysmography technique.
  • Airways Resistance measurement (RAW and sGAW): with metronome to assist the breathing process, full loop analysis with automatic and manual slope analysis.
  • Completely clear, glass enclosure ensures all around visibility, the seat loading will cope with heavy and obese subjects, the enclosure is available in two sizes, Standard and XL, the new multi link patient arm allows measurements both inside an outside the cabin.
  • Semi-disposable / reusable preVent® flow sensor, flow measurement from 0 to 15 l/s.
  • Integrated weather station (temperature and barometric pressure) for BTPS correction of the volume.
  • Low cost of operation and low maintenance.
  • Expair software suite with complete operator and patient guide included


The BodyBox can be combined with the following devices:

  • Micro 5000 spirometer
  • Micro 6000 spirometer
  • HypAir pulmonary function testing system
  • SpiroAir volumetric pulmonary function testing system
  • Ergocard CPX exercise testing system
  • FeNO+
  • Resmon PRO FULL V3 forced oscillation technique

Beside spirometry and lung volumes measurement by plethysmography, several options can be added in the BodyBox for comprehensive pulmonary function testing.

Lung diffusion capacity:

The BodyBox PFS offers the largest choice of lung diffusion capacity measurement (DLCO) with 6 possibilities:

  • Traditional Single breath DLCO with Helium tracer gas, using exhalation bag.
  • Real Time Single breath DLCO with Helium tracer gas, using rapid analyzer.
  • Real Time Single breath DLCO with Methane tracer gas, using rapid analyzer.
  • Intrabreath DLCO with Helium or Methane tracer gas.
  • Single breath double diffusion of CO and NO (DLCO-NO) with Helium tracer gas, allowing measurement of membrane diffusion (Dm) and capillary blood volume (Vc).
  • Rebreathing DLCO with Helium tracer gas, using rebreathing bag.

For single breath and intrabreath technique, you can choose the method to inhale the mixture:

  • the fastest and most economical: through a demand valve.
  • the most physiological, especially for patient with less cooperation: through an inhalation bag.

Lung volumes measurement:

In addition to TGV plethysmography method, alternative method to measure lung volumes can be added:

  • FRC-He: lung volumes measurement by Helium dilution in a closed circuit, using a rebreathing bag with O2 compensation and CO2 absorption.
  • FRC-N2: lung volumes and lung clearance index (LCI) measurement by multibreath Nitrogen washout.
  • N2 slope: measurement of the closing volume by single breath Nitrogen washout. This test is included when you choose FRC-N2 option.

Bronchoprovocation and Special Resistance Testing:

  • Provo 4 Provocation System: automated, software controlled, accurate and safe bronchial provocation testing.
  • RINT: resistance measurement using flow interruption technique. Ideal for children.
  • NEP (negative expiratory pressure): alternative method to detect and quantify expiratory flow limitation, which does not require performance of forced expiratory efforts nor a body plethysmography test.

Respiratory Mechanics Testing:

  • MIP – MEP (maximum inspiratory and maximum expiratory pressure): indicator of respiratory muscle strength.
  • SNIP: maximal nasal inspiratory pressure using a nasal cannula. A non-invasive indicator of diaphragmatic muscle fatigue.
  • P0.1: inspiratory occlusion pressure at 0.1 seconds, for respiratory muscle drive evaluation.
  • Static and dynamic compliance and resistance: measured by intra-esophageal balloon catheters.
