Sensor ventilator for
COVID-19
The COVID-19 virus is spread by direct
contact with an infected person's respiratory droplets (generated through
coughing and sneezing). Individuals can still become infected by coming into
contact with virus-infested surfaces and touching their faces (e.g. eyes, nose,
and mouth). The people infected with COVID-19 suffered from breathing issues,
lung issues, etc. In the pandemic, hospitals have been facing shortages of
ventilators. Many organizations have already designed low-cost emergency
ventilators, but they have not included a sensor or alarm system. To overcome
this problem, new ventilators have come on the market that have sensors or alarms.
These sensors track breathing and detect malfunctions if any. During the
COVID-19 crisis, a new open-source sensor and alert system made emergency
ventilators more helpful. It uses low-cost, widely available parts so that they
can be produced quickly and inexpensively to help address shortages.
The ventilator monitoring system uses a
similar tracking algorithm to the pressure signal measured in the patient's
airway. When the highest and lowest levels of the pressure signal are far apart,
the ventilator is working correctly. If those levels get too close together,
there might be a malfunction, such as a loose tube. It attaches to a
pressure-cycled ventilator and monitors the breathing cycle. The device, which
is smaller than a deck of playing cards, includes a pressure sensor, a
microcontroller, a buzzer, three buttons, and a display. It shows metrics
including respiratory rate and the pressure levels in the airway during
inhalation and exhalation. Clinicians use these metrics to monitor patients and
adjust ventilator settings. It sounds an alarm when the pressure is too high or
too low when the breathing is too fast or too slow, or too much time has
passed since the last breath.
