Household ventilators and oxygen concentrators are both commonly used medical equipment in our families. However, many people often confuse these two types together and mistake the ventilator as an oxygen concentrator, mistakenly thinking that the ventilator can also produce oxygen. In fact, it is not. So, what is the difference between a home ventilator and an oxygen concentrator?

Ventilators and oxygen concentrators are two essentially different medical devices. Let's first understand the working principles of ventilator and oxygen concentrator.

The normal breathing of our human body is due to the "active negative pressure difference" between the alveoli and the airway orifice generated by the body through the breathing action to complete the inhalation. After inhalation, the thorax and lung elasticity retract to produce the passive positive pressure difference between the alveoli and the airway orifice and exhale. Qi to meet the needs of physical ventilation. The home ventilator generates negative pressure in the chest cavity during the inhalation action during autonomous ventilation. Passive expansion of the lungs produces negative pressure in the alveoli and airway, which constitutes the pressure difference between the airway opening and the alveoli to complete the inhalation; the thorax and lung elasticity return after inhalation Retract and produce the opposite pressure difference to complete the exhalation.

The home ventilator is mainly suitable for patients with abnormal nose development, thick and thick pharynx, abnormal thyroid function, obesity and other patients when they have snoring or other sleep apnea syndrome symptoms!

The working principle of the oxygen generator is: the use of molecular sieve physical adsorption and desorption technology. The oxygen generator is filled with molecular sieves, which can absorb nitrogen in the air when pressurized, and the remaining unabsorbed oxygen is collected, after purification treatment, it becomes high-purity oxygen, and then it is delivered to it through a nasal catheter or an oxygen mask Our body. Generally speaking, it is not suitable for critically ill patients!

The main applicable groups of oxygen generators are: chronic bronchitis & emphysema and other respiratory diseases, high blood pressure & coronary heart disease and other cardiovascular and cerebrovascular diseases, cardiopulmonary dysfunction, sleep apnea syndrome and other sub-health conditions, and other causes Acute and chronic hypoxia symptoms.

In a word, the ventilator and the oxygen generator are two completely different concepts. The ventilator provides air flow like an electric fan to help and replace our breathing. The oxygen generator is like a sieve, filtering out the oxygen in the air, enriching and purifying it to the human body to improve our hypoxic state. Respiratory function can assist human breathing, but it cannot effectively improve the hypoxic state of the human body. Oxygen concentrator can increase the oxygen content and oxygen reserve in the blood, maintain the human blood oxygen saturation in a healthy state, and then improve the body's metabolic capacity and immunity for more serious diseases such as chronic obstructive pulmonary disease and heart failure, the combination of an oxygen generator and a ventilator will achieve a more ideal treatment effect!
