What Is The Difference Between a Home Ventilator And An Oxygen Concentrator ?
Household ventilators and oxygen concentrators are both commonly used medical equipment in our families.
However, many people often confuse these two types and regard ventilators as oxygen concentrators, mistakenly thinking that ventilators can also produce oxygen.
What is the difference between a home ventilator and an oxygen concentrator?
The working principle of the ventilator: The normal breathing of the human body is due to the "active negative pressure difference" between the alveoli and the airway opening generated by the body through the breathing action to complete the inhalation. Exhale due to the pressure difference to meet the needs of physiological ventilation. The inspiratory action of the household ventilator during spontaneous ventilation produces negative chest pressure, and the passive expansion of the lungs produces alveolar and airway negative pressure, thereby forming a pressure difference between the airway opening and the alveoli to complete the inhalation; after inhalation, the thorax and lungs elastically rebound. contraction, creating the opposite pressure difference to complete the exhalation.
Oxygen generator working principle: using molecular sieve physical adsorption and desorption technology. The oxygen concentrator is filled with molecular sieves, which can absorb nitrogen in the air during pressurization, and the remaining unabsorbed oxygen is collected, and after purification, it becomes high-purity oxygen, which is then transported to the inside of us. Generally not suitable for critically ill patients!
Applicable people for the ventilator: The home ventilator is mainly suitable for patients with abnormal nasal development, hypertrophy and thick pharynx, abnormal thyroid function, obesity and other patients who have snoring or other sleep apnea syndrome!
Applicable people for oxygen concentrator: chronic bronchitis & emphysema and other respiratory diseases, high blood pressure & coronary heart disease-like cardiovascular and cerebrovascular diseases, low cardiopulmonary function, sleep apnea syndrome and other sub-health states, acute and chronic insufficiency caused by other reasons oxygen symptoms.
