It can be said that since the outbreak of the epidemic, many people have been buried in panic, from snapping up Radix Isatidis to selling Lianhua Qingwen capsules, and now they are on ventilators. It can be said that this wave of operation is really dazzling.
The famous director of respiratory department in a hospital in Shanghai told his family with a ventilator, which is mainly used for the treatment of patients with severe pneumonia and respiratory failure. If we just prepare for COVID-19 infection, it is totally unnecessary, because there are few severe patients in COVID-19 now.
In a large number of sample data, it is rare to show that COVID-19 is infected by Omicron mutant. According to the research published by China Center for Disease Control and Prevention in June 18 Weekly, from March 22nd to May 3rd this year, the personal data of 338 16 non-severe patients in Shanghai showed that the severe rate was zero.
So, what is the ventilator like? What is its principle? Only by knowing this can we judge whether it is necessary to install a ventilator at home!
Ventilators can be divided into non-invasive ventilators and invasive ventilators. According to the principle of ventilator, ventilator can also be divided into medical ventilator and domestic ventilator.
In hospitals, medical ventilators monitor and feed back a series of parameters according to patients' symptoms, physical characteristics and oxygen saturation. Doctors use knowledge and all equipment to supply gas to synchronize with the patient's breathing. This complex equipment system requires high operation. As long as there is a little deviation, the ventilator may have problems and endanger the life of patients, so it is used in professional medical care.
Domestic ventilators are generally non-invasive ventilators, and the use conditions are very convenient and simple, which is a simplified version of medical ventilators. The domestic ventilator is easy to carry and achieve the purpose of treatment. Household ventilator consists of motor, motherboard, flow sensor, humidifier, mask and pipeline.
The following three types of patients generally need a home ventilator:
1, patients with sleep apnea syndrome, the most prominent performance of such patients is that they snore the most while sleeping. Usually obese people will have apnea and hypoxia.
2, gradually frozen people, that is, patients whose motor neurons are affected, have nothing to breathe, but these patients need to prepare a backup ventilator at home according to the development of the disease because they have no strength to breathe.
3. Patients with chronic respiratory failure. Patients with chronic lung disease, asthma and cor pulmonale will have a series of symptoms such as respiratory failure and hypoxia when their condition develops to a certain stage, and they need oxygen inhalation and respiratory support. However, such patients still need to use a ventilator under the guidance of a doctor. Help patients excrete carbon dioxide and inhale oxygen. But also according to the patient's condition. Sometimes you need a home ventilator to cooperate with the oxygen generator.
I don't know if the readers here still feel the need to have a ventilator at home.
Many families don't have such patients, so there is no need to prepare a ventilator. The price of ventilators generally ranges from 3000 yuan to 1000 yuan, and the ventilator with the largest sales volume is about 5000 yuan. Although ordinary families can afford this ventilator. But I don't think it is necessary at all. For such a ventilator that ordinary people can't use, the person who pays will take up space at home.
Of course, at the worst of the epidemic, some patients can only be treated in isolation at home. These patients can't go to the hospital because of breathing difficulties, so they think that when there is no epidemic, they should hoard a ventilator. I think such a family should hoard a ventilator!
First of all, we must understand the function of ventilator. Without this knowledge, we can't listen to others and prepare one. In this case, families with chronic respiratory diseases are not necessary at all. We should prepare a ventilator at home in case of emergency, but once ordinary patients have serious breathing difficulties, they will go to the hospital for treatment, and they don't know professional knowledge at home, which is useless at all. So there is no need for a ventilator.
Little friends, do you think what I said is reasonable? You can comment in the comments section below. We will discuss it together and look forward to your participation.
