Who uses N95 masks and has potential safety risks?

People who have diseases that affect their health Although N95 masks can achieve good protection effects and improve the invasion of viruses, not everyone can maintain complete health after using N95 masks. Especially for people who have lung diseases or cardiovascular diseases that affect their health, using N95 masks may affect normal breathing.

Because the air tightness of the N95 mask is relatively good, it is easy to increase the resistance during breathing. I have cardiovascular disease or decreased lung function, and I have more resistance in the process of breathing after wearing a mask. Because of this, many people get less oxygen during breathing, and they are prone to hypoxia.
