Plethysmograph

Acute respiratory measurement can take place with an intubated animal placed in a Type 853 plethysmograph box. This reduces the dead space in the respiratory path. The pneumotachometer is not needed and is replaced by the screens in the plethysmograph box.

• Investigate resistance and compliance without surgical intervention just by intubating
• Low dead space volume (no pneumotach in-line with the trachea)
• Possibility of continuous gas anesthesia and aerosol application
• Applications 
  – Toxicology 
  – Environmental studies 
  – Long term drug effects
