Difference between non-invasive ventilator and invasive ventilator

Recently, the epidemic has spread rapidly around the world, and foreign demand for medical equipment has increased dramatically, especially for invasive ventilators.

As the domestic epidemic situation is further controlled and the epidemic situation is spreading rapidly abroad, many companies report that overseas orders for epidemic prevention supplies such as ventilators have increased, and orders have even lined up.

Rooemed Medical mainly provides Non-invasive Ventilator, ICU ventilator,Ventilator with air compressor,Medical Ventilator,Breathing Machine.

1. From the classification of medical device management categories, non-invasive ventilator belongs to the second-class medical device, and invasive ventilator belongs to the third-class medical device (the third class has the highest level, which requires the certification of the State Drug Administration); the simplest way to distinguish, see medical Device registration certificate, type III or type II;

2. For patients, tracheal intubation (or tracheotomy) ventilation is invasive, while mask ventilation is non-invasive.

3. The invasive ventilator can be connected to high-pressure oxygen; (The advantage is that it can be used with high pressure, high flow, and high oxygen concentration to meet the needs of critically ill patients; Disadvantages: it must be driven by oxygen, and the oxygen consumption is large;)

4. Non-invasive ventilator can also be used with a non-invasive ventilator mask, but generally the oxygen consumption is relatively large and the oxygen concentration is high, so it cannot be replaced completely;

5. Imported high-end invasive ventilators have built-in turbines and can also be connected to high-pressure oxygen, which can achieve invasive and non-invasive integration, but the price is relatively high. Currently, the mainstream emergency ventilator on the market is still driven by oxygen (including imported). ;

6, so the invasive emergency ventilator can be divided into: with built-in turbine (only imported high-end machines have) and without turbine (mainstream is this)

7. The non-invasive ventilator has a built-in turbine, which can be used without an oxygen source; (disadvantages: only through indirect low pressure and low flow oxygen in the mask or breathing circuit, the pressure and oxygen flow are too low, and the oxygen in the critically ill patient does not enter the patient Lungs will cause hypoxia;)

8. The non-invasive ventilator pipe is added with a platform valve when it is used as an invasive ventilator. The pressure requirements are not high, the oxygen concentration is not high, and the flow rate is not high. Some invasive patients can be used for a short time, but they are severe. Patients, patients with high requirements are not easy to use;

9. Non-invasive ventilator is also divided into: single level, double level, etc.

10. In a word: ambulance should use invasive ventilator;
