What is the project to replace the lacking ventilator with a therapeutic device for sleep apnea syndrome?
With the rapid increase in the number of patients associated with the spread of new coronavirus infections, medical devices are in short supply in various places, and a large amount of ventilator is also required. Meanwhile, an open-source project has been launched to replace the artificial respirator by modifying the device for treating

GitHub-osresearch / airbreak: CPAP jailbreak to allow it to be used as a temporary ventilator

In the United States, in preparation for a shortage of ventilators, development of ventilators using bilevel positive airway pressure (BiPAP) , which does not secure the airway by intubation or incision into the body, is progressing. BiPAP is a method of regulating the pressure of air as the patient inhales and exhales, thereby supporting the patient's spontaneous breathing and promoting lung ventilation.
Like BiPAP, nasal continuous positive airway pressure therapy (CPAP) , which does not require incision, is mainly used to treat sleep apnea. CPAP terminals are cheaper than BiPAP terminals, but they do not have enough functionality to be used as ventilators for new coronavirus-infected individuals, and medical device manufacturer ResMed said, `` CPAP uses new coronavirus-infected persons for artificial respiration. to divert as a vessel, it is necessary to significant restructuring of the device 'and comments have been.
Trammel Hudson has modified the ' Airsense 10 ' CPAP terminal for the treatment of sleep apnea syndrome so that it can be applied as a ventilator for new coronavirus-infected persons. The image below is Airsense 10 modified by Mr. Hudson.
Airsense 10 has the function of sending air to open the airway, but it does not have the function of adjusting the air pressure according to the patient's breath like the BiPAP terminal.
Hudson remodeled Airsense 10 because he thought that the difference between CPAP and BiPAP terminals was not the hardware but the software program. By implementing a program that switches the pressure of the air sent according to the patient's breath, Airsense 10 is equipped with almost the same function as the BiPAP ventilator.
The modified Airsense 10 is not approved by the FDA at the time of writing the article, but Mr. Hudson himself asked experts and researchers to review it, and it is said that the verification of the performance is sufficient. On the other hand, Mr. Hudson said, 'No modification of the CPAP device can be used to treat new coronavirus-infected patients,' arguing that sufficient verification by experts is necessary. I will.
In addition, as for the artificial respirator which applied CPAP, the thing remodeled using Arduino Nano of a microcomputer board is also developed. You can understand how to make an open source ventilator using a 3D printer by reading the following article.
