Difference between oxygen concentrator and ventilator

Difference between oxygen concentrator and ventilator

Many patients with respiratory diseases are hesitant to buy oxygen concentrators and ventilators. Most people don't know much about oxygen concentrators and ventilators. Many people are asking patients with lung disease whether to buy oxygen concentrators or ventilators? Can the oxygen concentrator be used as a ventilator? Do you still need to continue to buy oxygen concentrator with respirator? Only by truly understanding the difference between ventilators and oxygen concentrators can we "tailor the medicine to the case" and achieve the therapeutic effect! Today, I will tell you the difference between a ventilator and an oxygen concentrator.

Both ventilators and oxygen concentrators are medical equipment, but the principles of use of ventilators and oxygen concentrators are different, and they are selected according to the conditions of different patients.

What is a ventilator？

Ventilator is a vital medical device that can prevent and treat respiratory failure, reduce complications, and save and prolong the life of patients. In modern clinical medicine, ventilator, as an effective means to replace the automatic ventilation function, has been widely used in respiratory failure caused by various reasons, anesthesia and respiratory management during major surgery, respiratory support treatment and emergency resuscitation, and plays a very important role in the field of modern medicine.

What is an oxygen concentrator？

Oxygen concentrator is a kind of machine that produces oxygen. Its principle is to use air separation technology. Most oxygen concentrators are molecular sieve oxygen concentrators, which use the adsorption performance of molecular sieve and use the large displacement oil-free compressor as the power through physical principles to separate nitrogen and oxygen in the air, and finally obtain high concentration of oxygen. This type of oxygen concentrator produces oxygen rapidly and has high oxygen concentration, which is suitable for oxygen therapy and oxygen health care of all kinds of people.

The difference between the two (oxygen concentrator and ventilator)

■ The ventilator outputs air, which is an effective means to replace the automatic ventilation function manually; The oxygen concentrator outputs oxygen to improve the oxygen content of the human body. Generally speaking, the ventilator is to ventilate the patient, and the oxygen concentrator is to ventilate the patient.

■ The respirator can adjust the frequency, size and intensity of breathing, while the oxygen concentrator can only adjust the oxygen flow.

■ Ventilators are used in respiratory failure caused by various reasons, anesthesia and respiratory management during major surgery, respiratory support treatment and emergency resuscitation. Oxygen concentrator is an auxiliary means to correct pathological hypoxia, such as respiratory failure, chronic tracheitis, cerebrovascular disease, coronary heart disease, etc.

Use ventilator or oxygen concentrator?

When choosing to use the ventilator and oxygen concentrator, generally observe whether there is carbon dioxide retention.

What is carbon dioxide retention? Like hypoxia, it is a special pathological term. Respiratory dysfunction caused by various reasons leads to hypoxia, which increases, accumulates and retains carbon dioxide, affects normal cell metabolism and gas exchange, thus leading to carbon dioxide retention and a series of clinical manifestations.

In the early stage of some lung diseases, there is only hypoxia and no carbon dioxide retention. Because the diffusion rate of carbon dioxide is 20 times that of oxygen, carbon dioxide exchanges more than oxygen in the same time. As long as there is no serious ventilation problem, there is generally no problem of carbon dioxide retention. This stage is generally called type I respiratory failure. So if the lung function is reduced, but there is no problem of carbon dioxide retention, in this case, it is generally OK to buy an oxygen concentrator.

If the pulmonary function is further reduced and the pulmonary ventilation capacity is further reduced, there will be not only hypoxia, but also carbon dioxide retention. This stage is called type II respiratory failure. In this stage, the patient's small airways are severely blocked and gas exchange is difficult. In this stage, simple oxygen inhalation cannot solve all problems. Because the body is prone to carbon dioxide retention due to insufficient ventilation, the ventilator can help to discharge carbon dioxide. At the same time, the oxygen concentrator needs to provide oxygen to supplement the oxygen saturation of the body. The combination of the two can really achieve therapeutic effect.

Type I respiratory failure

Oxygen deficiency+no carbon dioxide retention=oxygen concentrator

Type II respiratory failure

Hypoxia+carbon dioxide retention=oxygen concentrator+ventilator
