Some researchers believe that there are currently six different "types" of COVID-19, which differ in severity and symptoms. However, in the treatment process, most patients need to use a breathing ventilator machine.
As a medical apparatus company, let Pigeon Medical introduce the six types of COVID-19.
(1) The first type of new coronary pneumonia, which is "similar to flu without fever," it is usually accompanied by headache, loss of smell, muscle pain, cough, sore throat, and chest pain. The chance that such patients will eventually need a ventilator is 1.5%.
(2) The second type is "similar to flu with fever". Symptoms include loss of appetite, headache, loss of smell, cough, sore throat, hoarseness and fever. More than 4% of patients will require respiratory support.
(3) The third type is simply called the "gastrointestinal" type. These patients do not cough, but they have headaches, diarrhea, loss of smell, loss of appetite, sore throat, and chest pain. Only slightly more than 3% of these patients need respiratory support.
(4) The fourth type of patients, also known as "grade one severe" patients, often have fatigue, accompanied by headache, loss of smell, cough, fever, hoarseness and chest pain. They have an 8.6% chance of needing respiratory support.
(5) The fifth type is called "second-degree severe" new coronary pneumonia. Patients may have all the symptoms of the fourth type, as well as decreased appetite, sore throat, and muscle pain. The main characteristic of such patients is trance, about 10% of patients require respiratory support.
(6) The sixth type is "third-grade severe" new coronary pneumonia. Patients have all the symptoms of the fifth type, as well as abdominal pain, shortness of breath and diarrhoea. As the most severe type, nearly half of these patients will require hospitalization, with a 20% chance of requiring respiratory support.
When the patient's symptoms improve, the respiratory function gets better significantly, and the following main characteristics are achieved, removal of breathing ventilater machine can be considered:
(1) Lung function is good, FiO2<30%.
(2) The patient is conscious and blood gas analysis is normal or nearly normal.
(3) Cough and swallowing reflex are existing, and lung infection has been basically controlled.
(4) The cardiac function is good and the circulatory function is stable.
(5) When the auxiliary respiratory rate reaches 6-10 / min, and the patient's breathing is stable, ventilation and oxygen saturation are normal, the breathing ventilator machine can be removed.
However, during the process of removing the breathing ventilator machine, the patient may show intolerance such as irritability, increased breathing rate, and decreased blood oxygen. Then, the weaning process should be stopped or slowed down.
