The above statement is not very accurate. The thing is, ventilators are divided into invasive and non-invasive. Other departments do not have as many invasive ventilators as ICUs. There are more than one or two non-invasive ventilators in respiratory medicine.
First, let¡¯s explain what is invasive and what is non-invasive. The difference lies in the word ¡°creation¡±, which is trauma. The invasive and non-invasive ventilators correspond to invasive mechanical ventilation and non-invasive mechanical ventilation respectively.
? Mechanical ventilation, to put it simply, refers to the connection between the machine and the patient. Invasive, the patient is intubated and connected to a ventilator. Non-invasive, it uses a mask or other non-harmful means to connect the ventilator and the patient.
Non-invasive ventilation, broadly defined, not only refers to the use of ventilators, but also includes diaphragm pacing. The latter are rarely used clinically and are difficult to see. Technologies that are rarely used clinically have always had only one reason: the mismatch between treatment costs and effects.
Non-invasive ventilators can be widely used in respiratory medicine. For the same reason, the cost is less, patients are more affordable than invasive ventilation, and the efficacy is good. Providing non-invasive ventilation at an early stage can reduce the possibility of the condition worsening to the point of requiring invasive ventilation.
Invasive ventilators can also be used for non-invasive ventilation. So in the ICU, you can see that some patients may need non-invasive ventilation after extubation and use invasive ventilators directly. Anyway, there are many ventilators in the ICU. However, it is impossible to turn a non-invasive ventilator into an invasive ventilation. Because non-invasive ventilators are cheap, indicators such as compressor power are destined to fall far short of the requirements for invasive ventilation.
Ventilators are precious, especially invasive ones, and must be managed by a dedicated person, usually a designated nurse. Nurses are also the ones who usually perform maintenance and management such as disinfection and management of ventilators.
Nurses can adjust some simple parameters through ventilator training, but only doctors can adjust ventilator parameters for critically ill patients, because only doctors can understand the patient's monitoring indicators.
How to adjust the parameters of the ventilator can be said to be the skill of professional doctors related to the study of human respiration.
Having time this morning, the enthusiastic teacher Xin Yanjun stood next to the ventilator and gave a lecture to the new students: "Do you know what we adjust the ventilator parameters based on?"
¡°The most commonly used and most useful monitoring indicator should be the patient¡¯s blood gas analysis.¡± Xie Wanying said.
Hearing her quick answer, Xin Yanjun was stunned for a moment, but he didn't expect her to be so accurate. Ventilator management has always been the focus of internal medicine. It is not easy for a surgical student to answer this question on his first day in the respiratory medicine department.
Xie Wanying¡¯s answer doesn¡¯t look like she just learned it from a book, but has some clinical experience. Xin Yanjun wondered if she had learned relevant knowledge in clinical practice.
Teacher Xin¡¯s suspicion is right. Xie Wanying just can¡¯t be honest. She was born again. When I used to work in the laboratory department, it was most common for the ICU to perform blood gas analysis on patients on ventilators every three days, or even do these tests urgently in the middle of the night. With the work experience she has accumulated over the years, it is entirely possible that she understands ventilator monitoring indicators better than the average physician.
Laboratory work must be connected with clinical work, and these work contents will follow clinical learning and research.
"There seem to be many modes of the ventilator, but in fact the principle of the ventilator is this. There is no sensor at the beginning, the machine directly inflates the patient's airway. With the sensor, the machine can sense the patient's breathing and adjust accordingly. Make the breathing situation of the machine and the patient more coordinated. The adjustment can be controlled by the computer of the machine, or it can be operated by medical staff. Based on this principle, there are multiple computer modes."
