Have you ever heard of "cryogenic burns"? As the temperature continues to drop, many people also use various "heating artifacts". However, although the "artifacts" can bring warmth and comfort, they can easily get injured if used incorrectly.
You may wonder, can you get burned at low temperatures? Ordinary burns and scalds are usually wounds caused by contact with hot gases, flames, boiling water, etc. This trauma is often obvious and easy to detect and avoid. And low-temperature scalds, a bit like "boiled frogs in warm water", as long as the temperature reaches 44 for 6 hours, it can cause ** damage.
Several common heating equipment on the market can reach different temperatures, but on the whole, the average temperature actually used is between 40 and 50, which is in the "high incidence range" of low-temperature burns! Infants, young children, the elderly, paralyzed patients or drunk people often become "high-risk groups" for low-temperature burns due to their sluggish sensory responses.
The main influencing factors of burns are the maximum temperature at the time of contact and the contact time! So keep these two things in mind: get rid of the heat source and cool down quickly. Then, the five first aid steps of "flushing, taking off, soaking, covering, and sending" were quickly opened by using the on-site conditions.
One flush: When a scald accident occurs, it is necessary to rinse the scald area with running cold water for at least 20 minutes as soon as possible to reduce the heat of the surface and reduce further damage.
Second off: After rinsing and soaking thoroughly, carefully remove clothing in cold water. If the wound sticks to the clothing, cut it carefully to avoid forced tearing.
Three bubbles: the pain is obvious, and it can be soaked in cold water for 10 to 30 minutes for pain relief.
Four covers: Gently cover the affected area with sterile gauze, if no gauze is available, you can use a clean and dry towel instead. Remember not to cover it with hairy or flocculent items to avoid adhesion to the wound.
Five sends: Hurry up and send them to the hospital for treatment! Again: don't smear anything without permission, give it to the doctor!
