Detailed introduction

Non-invasive Airway Mechanics

部气流进行分别测定并计算得出特殊气道阻力SRaw和特殊 气道导率SGaw。 The system uses a dual-chamber plethysmograph to measure the head and chest airflows of animals and calculate the special airway resistance SRaw and special airway conductivity SGaw . Can be equipped with aerosolized drug delivery system.




Product main features:
Can observe multiple animals at the same time, suitable for long-term tracking research;
相关性; SRaw and SGaw parameters are highly correlated with airway resistance measured invasively;
Preparation of animal experiments is more complicated than whole body plethysmography;
The animal is completely non-invasive, and the test is completed in awake state without anesthesia;
Can be equipped with aerosolized drug delivery module;

Main detection parameters:
Specific Airway Resistance
Specific Airway Conductance
Tidal Volume
Minute Volume
Time of Inspiration
Time of Expiration
Peak Expiratory Flow
Peak Inspiratory Flow
Respiratory Rate
Explanations and more parameters



The EMMS non-invasive airway mechanics system uses a classic Pennock style double-chamber plethysmograph to measure nasal and thoracic flow. The animal is placed in a double-chamber plethysmograph (eg. PLY 230 for guinea pig), and is restrained in the chamber with a rubber neck collar. This neck collar also provides an airtight seal between the thoracic and nasal chambers. Flow in the two chambers is measured across two pneumotachographs in the plethysmograph wall. A bias flow air supply is used to prevent build-up of CO2 in the plethysmograph, and may also be used to pull aerosol through the nasal chamber.
