Description:

The ventilation waveform generator is a device currently used for testing CPAP devices and aiding patients experiencing restricted breathing. It is similar in function to what is desired for the NOSE. A linear motor is programmed to create positive pressures through a tube in conjunction with an air compressor as depicted in the patent figure below.

Pros and Cons:

Pros:

The ventilation waveform generator creates pressure changes similar to what the NOSE will need to accomplish for testing the NED.

Cons:

The generator would need to be fitted exactly to the NED device.

Cost for the generator is high, and they are not easily accessible.
