With the improvement of people’s living standards, obstructive sleep apnea syndrome is more and more common in clinical practice, and its incidence is high, which seriously affects the quality of life and life span of patients. At this point, the portable ventilator is particularly important.
8-bit Laser Bee MCU EFM8LB12F32 Portable Ventilator System
A portable ventilator requires the use of two pressure sensors to measure the pressure on both sides of the baffle in the ventilation pipe, accurately and quickly collect the pressure value and timely adjust the revolution of the fan to provide a comfortable air supply for snoring people, which is the most critical problem.
At the same time, the application direction of the product in people with obstructive sleep apnea syndrome, so the volume of the product is required to be small, convenient to carry on business trips, and the price is also low.
In the 16th century, Flemish doctor Andreas Vesalius described ways to keep choking animals alive by inserting tubes into their tracheas and blowing air into their lungs. In 1555, it didn’t get much traction. But today, Visari’s description is believed to be the first description of a mechanical ventilator — an important therapeutic tool in modern medicine. To understand the value of a ventilator, we need to understand how the respiratory system works.
The human body expands chest breathing by contracting the diaphragm. So air is drawn in to fill the alveoli — the thousands of little sacs in our lungs. Each of these pellets is surrounded by a network of capillaries filled with blood. Blood takes in oxygen from the inflated alveoli and releases carbon dioxide. When the diaphragm relaxes, carbon dioxide is exhaled along with oxygen and other gases. This process occurs automatically when our respiratory system is functioning normally, but it can be disrupted by a variety of factors. Sleep apnea, for example, causes the diaphragm muscle to stop contracting. Asthma can cause inflammation in the airways, which can block the flow of oxygen. Pneumonia is often caused by bacterial or viral infections that attack the alveoli themselves.
Foreign pathogens kill lung cells, triggering an immune response that can lead to deadly inflammation and fluid buildup in the lungs. All of these conditions can cause the lungs to fail to function properly. But a mechanical ventilator takes the place of this process, allowing oxygen into the body when the respiratory system is not working properly.
Ventilators can bypass blocked airways and deliver oxygen-rich air to help the damaged lungs diffuse more oxygen.
