There are many brands and models of oxygen concentrators on the market. Many consumers are dazzled and don’t know how to choose. They don’t know much about 5L oxygen concentrators.

　　1. Machine life.

　　Generally, the power of the 5l oxygen concentrator is much stronger than that of the 3L, and it can withstand a higher workload. During long-term high-flow operation, the 3-liter engine may be overloaded, shortening its lifespan, or even malfunctioning.

　　2. Disease progression.

　　Many chronic lung diseases (such as COPD) are progressive and irreversible, and the disease will only get worse over time. Buying a 5l oxygen concentrator at the beginning is actually the most economical choice!

　　3. Differences in oxygen concentration.

　　Taking the oxygen inhalation concentration (inhaled alveolar oxygen concentration) required by COPD patients as an example of 29%-35%, the oxygen concentration of 3 L is about 28.39%. Although it can meet the general medical needs, it is difficult to meet the needs of long-term oxygen therapy patients. needs. The oxygen concentration of the 5l oxygen concentrator is about 33.39%, which has a therapeutic effect and can effectively relieve the symptoms of the patient.

　　Seeing this, I believe you already have a certain understanding of which oxygen generator to choose, but when purchasing a 5l oxygen concentrator, the manufacturer of the 5l oxygen concentrator still reminds you to choose a professional through regular channels.
