Amplifier for measuring respiratory rate
Amplifier for measuring respiratory rate
The unit can only be operated on anesthetized species. The external diameter of the tracheal cannula developed to this unit, determines on what species the unit can be used. The present design allows four applications (rat, rabbit, dog, pig). The removable thermo sensor is placed in the cannula, which measures the respiratory rate based on the temperature difference of the air coming from the lungs. The sensor is interchangeable and can be connected to any tracheal cannula. In case of failure the replacement can be performed without calibration.
