Novel coronavirus and "ventilator"

The current "Pneumonitis Diagnosis and Treatment Program for New Coronavirus Infection (Trial Fifth Edition)" was released on February 5th, which once again mentioned some ventilator aspects. There are also many friends who added me to WeChat. I have no symptoms, but I keep seeing media reports about pneumonia and ventilator. In this place, I will briefly introduce the situation of the "new crown and ventilator", so as not to confuse everyone when choosing a ventilator, this article is just a guide for the sake of introduction.

Ventilator

Real "ventilator"


Respiratory support: (1) Oxygen therapy: Severe patients should receive nasal cannula or mask to inhale oxygen, and assess in time whether respiratory distress and / or hypoxemia is relieved. (2) High-flow nasal catheter oxygen therapy or non-invasive mechanical ventilation: When patients with respiratory distress and / or hypoxemia cannot be relieved after receiving standard oxygen therapy, high-flow nasal catheter oxygen therapy or non-invasive ventilation can be considered. Emphasize "if the condition does not improve or worsen within a short period of time (1 to 2 hours), tracheal intubation and invasive mechanical ventilation should be performed in a timely manner." (3) Invasive mechanical ventilation: adopting lung protective ventilation strategy, that is, mechanical ventilation with small tidal volume (ideal weight of 4-8mL / kg) and low inspiratory pressure (platform pressure <30cmh2o) to reduce ventilator-related lung injury. (4) Salvage treatment: For patients with severe ards, it is recommended to perform lung expansion. In the case of sufficient human resources, prone ventilation should be performed for more than 12 hours per day. If prone position ventilation is not effective, if conditions permit, extracorporeal membrane oxygenation (ecmo) should be considered as soon as possible. ——Fifth Edition of Diagnosis and Treatment Plan


The description of the ventilator in the fifth edition of the "Diagnosis and Treatment Program" appears in Article 8. The red font is marked out by me, and there are five places in total. Everyone may be surprised. Why don't you see the word "ventilator"? "Ventilator" is our usual colloquial name. In formal situations, the general name is: mechanical ventilation, which is relative to our normal ventilation. Regarding mechanical ventilation, it is basically a compulsory course for all respiratory physicians at the university level. This is also the name of a thick professional book.

Because some severely ill patients had no obvious dyspnea and manifested as hypoxemia, it changed to "Severely ill patients often have dyspnea and / or hypoxemia one week after the onset of illness, and the severe cases progress rapidly to acute respiratory distress syndrome, sepsis Shock, metabolic acidosis that is difficult to correct, and coagulation dysfunction, etc.


The most common condition for pneumonia caused by a new crown is hypoxemia, that is, we often say that the oxygen saturation is low. The most direct solution to this symptom is to inhale oxygen. Then use mechanical ventilation as appropriate, which is what we call a "ventilator." The "ventilator" of mechanical ventilation is the real "ventilator".


Ventilators used in hospitals are usually large medical non-invasive / invasive dual-purpose machines. Most of them look like this!

But the hospital ventilator should be provided for many patients, so the ventilator used is relatively large and not suitable for use at home.


Hunan Jintai hardware mechanical and electrical import and Export Co., Ltd. has several small and flexible respirators, which can provide enough respiratory support. For patients with respiratory failure, other aspects can also be used for the clinical treatment of sleep apnea hypopnea syndrome, heart failure and other applications. It is a ventilator suitable for patients to use at home.
