Home 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 generator?

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

The normal respiration of our human body is due to the "active negative pressure difference between the alveoli and the airway opening" produced by the body through the breathing action, and the inhalation is completed. After the inhalation, the thorax and lung elasticity retract to produce the passiveness of the alveoli and the airway opening. Exhale with a positive pressure difference to meet the needs of physiological ventilation. The home ventilator generates negative pressure in the chest cavity when inhaling in spontaneous ventilation. Passive expansion of the lungs results in alveolar and airway negative pressure, which constitutes the pressure difference between the airway orifice 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, hypertrophy 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 transported to it through a nasal catheter or an oxygen mask Our body. Generally not suitable for critically ill patients!

The main applicable people for oxygen generators are: chronic bronchitis & emphysema and other respiratory diseases, hypertension & coronary heart disease, cardiovascular and cerebrovascular diseases, cardiopulmonary dysfunction, sleep apnea syndrome and other sub-health conditions , Acute and chronic hypoxia symptoms caused by other reasons.

To put it simply, a ventilator and an 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 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 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 concentrator and a ventilator will achieve a more ideal therapeutic effect!
