Buxco® Large Animal Whole Body Plethysmography

Large animal respiratory data

WBP is an acronym for Whole Body Plethysmography.  WBP is a way to measure respiratory function in animals (or people) without the use of anesthesia or restraint.  The system relies on a specially designed chamber in which the subject is placed.  A sensitive pressure transducer is connected to measure pressure changes inside the chamber.  Since the chamber is fitted with screen pneumotachs which allow air to pass outside the chamber, the small pressure changes in the chamber are related to flow.  And so, the chamber is a plethysmograph.  From these small flows signals, utilizing special algorithms Buxco FinePointe software derives ventilatory and bronchio constriction parameters.

Key Features

  • Species:  Rabbit, ferret, cat, dog, pig,  NHP*
  • Up to 16 animals can be supported simultaneously
  • Variable bias flow pump provides fresh air supply
  • Digital Preamplifier / controller with USB interface
  • Chambers have integrated pneumotach and reference chamber
  • Flow transducer and optional temperature and humidity probe
  • Integrated nebulizer controller supports Aerogen nebulizer

    *NHP uses chaired resraint


Key Benefits

  • Halcyon – Chambers incorporate patented noise suppression design
  • Multiple large animal chamber sizes supported by same hardware, sensors, and software
  • High fidelity differential pressure transducer - provides drift free air flow signal
  • Pre-calibrated digital temperature and humidity probes do not require adjustment
  • FinePointe software integrated study design and subsequent automated reporting
  • Where applicable, standard animal crates are utilized within the chamber for easier animal handling, reduced chamber cleaning, and quicker animal acclimation
