Body plethysmograph NAM-XMR

for animalsfor animal research

The Non-Invasive Airway Mechanics (NAM) developed by Tow-Int Tech can measure the respiratory parameters of awake and restrained animals. It can measure nasal flow and thoracic flow, specific airway resistance (sRaw), and specific airway conductance (sGaw) respectively. Non-Invasive Airway Mechanics separates the head and body of an animal into a head chamber and a body chamber, enabling the measurement of nasal flow and thoracic flow respectively. By analyzing the delay of nasal flow relative to thoracic flow, specific airway resistance (sRaw) and specific airway conductance (sGaw) can be obtained, allowing for a more accurate assessment of animal airway resistance. The system features an adjustable bias - flow system that supplies fresh air to prevent the accumulation of carbon dioxide. It is used for research such as long - term monitoring of animals in a conscious and restrained state. Without the need for surgery or anesthesia, it can achieve rapid monitoring of a large number of animals. Non - invasive and no anesthesia required; monitors animal respiratory indices when the animal is awake. Specific airway resistance (sRaw) and specific airway conductance (sGaw) can be obtained, providing more comprehensive data for research. Integrates nebulization drug delivery, respiratory detection, and bias - flow control. Automatic calibration function The specially designed animal fixator and dual - chamber plethysmograph ensure airtightness while minimizing the restraint on the animal.
