Faced with high-intensity work, chronic diseases or oxygen inhalation needs of special groups, home oxygen concentrators have gradually become a healthy tool to improve the quality of life.

However, the purchase cost of thousands of USD and the use threshold of high-function models have made many families entangled: Do they need to buy for a long time? Can short-term needs be solved at a low cost?

In fact, in addition to direct purchase, renting an oxygen concentrator has become a more flexible solution-it can not only try out the adapted model, but also respond to sudden health needs.

Faced with oxygen concentrators of different specifications on the market, how to quickly locate needs and find cost-effective options?

This article will provide the core parameters, functions and usage scenarios of several oxygen concentrators so that you can avoid pitfalls when purchasing or renting.

Purpose of oxygen inhalation

Oxygen concentrators are not "the larger the flow, the better", and different usage scenarios correspond to different specifications:

Daily health care: For healthy people or people who need daily health care, a 1L/minute oxygen concentrator is a good choice.
This type of oxygen concentrator is mainly used to provide high-concentration oxygen to help improve the health of the respiratory system and enhance physical fitness.

Medical auxiliary treatment: For people with specific health problems, such as the elderly or patients with cardiopulmonary diseases, 3L/minute and 5L/minute oxygen concentrators are more suitable.
3L/minute oxygen concentrators are suitable for daily health care and treatment of some mild diseases, while 5L/minute and above oxygen concentrators are more suitable for patients who need high-flow oxygen, such as patients with cardiopulmonary functional diseases or special patients who need high oxygen flow.

Key reminder: Health-care oxygen concentrators cannot replace medical use, and patients with diseases need to follow the doctor's advice to choose professional models.

Core parameters: three major indicators

1. Oxygen concentration > 90%:
When the oxygen concentration is lower than 90%, it cannot meet the needs of effective oxygen therapy. It is recommended to choose a molecular sieve oxygen concentrator-through physical adsorption technology to separate nitrogen, the oxygen concentration is stable at 93%±3%, which is the current mainstream technology.

2. Noise < 45 decibels:
Excessive noise may affect rest (especially those who breathe oxygen at night), and models with variable frequency noise reduction design can be given priority.

3. Continuous operation capability:
For medical purposes, the machine needs to support 24-hour uninterrupted operation and good heat dissipation performance to avoid overheating and shutdown.

Tips for safe use

· The oxygen concentrator should be kept away from fire, high temperature and humid environment to avoid the risk of oxygen combustion;

· The humidification bottle should be cleaned with pure water every day and disinfected every week to prevent bacterial growth;

· The duration and flow of oxygen inhalation should be in accordance with the doctor's advice to avoid excessive oxygen inhalation leading to oxygen poisoning.

Whether it is daily health care, short-term rehabilitation, or reserving resources for sudden health needs, the choice of home oxygen concentrator is essentially a long-term plan for family health.

After clarifying your own needs and being familiar with the core parameters, you need to further evaluate the actual use scenario: if you only need short-term emergency (such as postoperative recovery, seasonal conditioning), or want to experience the adaptability of the model first, renting an oxygen concentrator can not only reduce the initial investment cost, but also ensure the safety of oxygen use through regular maintenance by professional institutions.
