A device to visualize breathing

Introduction

Currently, a researcher from Ohio university drive an ENS study which consist of breathing visualization in order to tell to the brain that even we don't feel airflow we are currently breathing air.
The technique of breathing consist of breath near a mirror for seen the fog created by our breathing.
I directly thought that it was an interesting idea. So thanks to her for this.


So with this idea I have "created" a device for see, hear and feel our breathing. I think that if more senses are stimulated then maybe our brain will understand better that we are currently breathing air. It is just a theory I'm not a scientist.
Also, I have a hope that those simulations can increase the breathing command drive.
As you know, ENS can create dyspnea and decrease the breathing command drive due to the lack of stimulation of the mechanical and temperature (TRP) receptors in the nasal mucosa. These phenomena also create the central sleep apnea.

The device

Device to visualize breathing
The device, sorry for the horrible cable management.

The device is made with a pressure sensor (1), a nasal cannula (2), a LED (3) and a fan (4) linked to a microcontroller (5), the operation is very simple. When the pressure is negative (inspiration), the LED and the fan are turned ON. When the pressure is positive (expiration), the LED and the fan are turned OFF.
It is just as simple as this.
The fan is placed near the skin in order to feel the airflow, I don't know which part of the body is the more appropriate to feel this airflow.
I also don't know if there is any sense to place a fan near the skin when the brain is waiting the mucosa receptor signals. It is maybe a completely no sense.
Maybe in the future I will send the airflow in the nasal cavity via a pipe but it is more complicated and the airflow can dry the mucosa.

Conclusion

I will write an article in order to tell you the eventual results and the possible improvement of the device.
Keep in mind that I'm not a scientist and this device is possibly useless.
If some of you are interested, I will do a short tutorial to show you how made the device and where buy the components.
