Lung volume measurement for large animals

emkaPACK4G is a non-invasive telemetry system, widely used in large animal studies to monitor the physiology of freely moving large animals, such as dogs, primates, sheep or minipigs,

An external transmitter is worn into a jacket and monitors respiration based on inductive plethysmography. Thorax & abdomen volumes measurements are captured non-invasively, wirelessly transmitted by Bluetooth to a receiver and processed to derive pulmonary parameters.





Can be used for inhalation studies


Long term recording on several animals


Bluetooth data transmission prevents any data cross-talk, allowing each subject to freely to move, single or group-housed in its room, during the acquisition (max. 32 to 48 subjects per room).

The whole system is compact, with:

  • One external emkaPACK4G transmitter worn by each subject, into a jacket.
  • Belts,directly connected to the emkaPACK4G transmitter
  • One or several receivers positioned in the animals’ room, within 10 meters distance from their associated transmitters. A single receiver can communicate with up to 16 transmitters and is powered and transmits data through a single Ethernet cable.

emkaPACK4G takes full advantage of emka TECHNOLOGIES software suite:

Lung volume acquisition in IOX2 software:
  • Easy & seamless calibration of respiration belts
  • Information on belt connection by software
  • Synchronized video
Data analysis with RIP module:

ecgAUTO post-processing software allows fast analysis of cardiovascular, pulmonary (lung volume) and neurological data. In ecgAUTO software, the RIP (Respiratory Inductive Plethysmography) analyzer produces:

  • Duration of breath,
  • Duration of inspiration/expiration,
  • Breathing rate,
  • Inspired/expired volume,
  • Minute volume,
  • Max flow during inspiration/expiration,
  • Thorax-abdomen shift – time or angle (when 2 belts used)

In addition to respiration through thorax and abdominal inductance belts, emkaPACK4G optionally allows the acquisition of:

  • 9 lead ECG
  • temperature
  • posture & activity (3 axis + total acceleration)
  • blood pressure from oscillometric cuff (NIBP), easyTEL+ implant or vascular access port (VAP)
