Ventilator and Oxygen Concentrator—Can replace each other?

Ventilator and Oxygen Concentrator

Whether need to buy an oxygen concentrator if have already a ventilator? Or if have an oxygen concentrator already, then no need to buy a ventilator? Can buy only one of them, can they replace each other?

First of all, we have to understand the role of homecare oxygen concentrators and ventilators.

What is the effect of the oxygen concentrators ?

Oxygen concentrator uses molecular sieve physical adsorption and desorption technology to produce oxygen. It is a safe and convenient machine for producing high-concentration oxygen.

Oxygen concentrators are generally suitable for respiratory diseases such as pneumonia, bronchitis, emphysema, pulmonary heart disease, etc., as well as cardiovascular and cerebrovascular diseases, such as, hypertension, heart disease, coronary heart disease, or high altitude hypoxia,and people who are prone to hypoxia.The characteristic of oxygen concentrator is that oxygen inhalation directly increases the oxygen content of the arterial blood. Oxygen therapy could be alleviating the symptoms of hypoxia in time, but it has only a partial and gradual effect on eliminating the cause of hypoxia. Oxygen therapy is the main method for correcting physiological hypoxia and environmental hypoxia, also can prevent diseases caused by environmental hypoxia. For correcting pathological hypoxia, oxygen therapy is an important auxiliary means. For emergency rescue, oxygen therapy is one of the important way.

What is the role of a ventilator?

Ventilator is a medical device that can replace or improve human breathing, can increase lung ventilation, and improve respiratory function.

Ventilators are generally suitable for patients with lung failure or airway obstruction that cannot breathe normally, those with abnormal nasal development, those with enlarged and thick pharynx, those with abnormal thyroid function, and those with obesity who have snoring or other sleep apnea syndromes. Use ventilator when they have symptoms! To help the patient complete the breathing process of exhalation and inhalation.Ventilator, also called  mechanical ventilation in medicine (Ventilation).The process of natural breathing is to expand the chest cavity to form negative pressure, so that air enters the lungs; mechanical ventilation is to force air above atmospheric pressure into the lungs, which is called “breathing”, not as “purge”. 

Ventilators can be subdivided into Non-Invasive Ventilation (NIV) and Invasive Mechanical Ventilation (IMV) according to different connection ventilation methods. The equipment used is non-invasive ventilator and invasive ventilator.Among them, non-invasive ventilators generally ventilate through a closed face mask, while invasive ventilators need to insert the ventilation pipe into the intake tube.

Can oxygen generator and ventilator be used together?

The ventilator and the oxygen generator are completely different concepts.The ventilator provides air flow like an electric fan to help and replace our breathing. The oxygen concentrator is like a sieve, filtering out the oxygen in the air, enriching and purifying it to the human body to improve our hypoxic state. Ventilator can assist human breathing, but it cannot effectively improve the hypoxic state of human body, while 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 concentrator and a ventilator will achieve a more ideal treatment effect!

Therefore, the oxygen concentrator and the ventilator cannot be replaced for each other. The oxygen concentrator has the function of an oxygen concentrator, and the ventilator has the function of a ventilator. In the actual use process, according to the patient’s  condition, when both of them need to be used, here recommended two used in combination.
