four cooling off

Physical cooling refers to the method of reducing the temperature of objects by physical heat absorption or dissipation. It can be used to cool patients with high fever. For example, cooling the head can prevent cerebral edema, reduce brain cell metabolism, and improve the tolerance of brain cells to oxygen deficiency. The methods included the following: - Rubbing bath method: such as warm water rubbing bath, alcohol rubbing bath, Chinese medicine liquid rubbing bath. Warm water of 30 - 37 degrees Celsius was generally chosen for the warm bath, because cold water was highly irritating and would shrink pores, which was not conducive to heat discharge, and may aggravate the condition. Alcohol bath was not common because of the allergy of some people. If it was used, it was the same as wiping with a towel. It was not recommended to use the bath method for physical cooling in infants and patients with blood diseases. - Ice compress cooling method: like ice pack cooling, ice cap cooling, etc., can wrap the ice with a towel to cool the armpit, neck and other large blood vessels of the patient with fever. Pay attention to avoid direct contact with the ice to prevent frostbite. - Venous cooling. - Enemas. - Medical ice blanket cooling method, etc. In the process of physical cooling, there may be local frostbite, diarrhea, cardiac arrest, general reactions, subcuticular bleeding, local pressure sores, alcohol allergy, chemical cooling bag fluid extravasation and skin damage, and other complications. It needs to be treated according to the specific symptoms. In addition, if physical cooling fails to reduce the body temperature to normal in a short period of time, it is recommended to go to the hospital in time to avoid delaying the illness.

Here are five physical cooling methods: 1. Wiping bath method: - Warm Water Wipe Bath: Use warm water of about 32 - 34 ° C to wipe the patient's skin all over the body. The wiping time can be slightly longer on the armpits, groin and other parts with rich blood vessels. It is best not to wipe the chest, abdomen and other parts sensitive to cold stimulation. - Alcohol scrub (Due to alcohol allergy in some people, use with caution): The wiping area is similar to a warm water scrub. 2. Ice compress cooling method: - Ice bag cooling: wrap the ice with a towel and place it on the armpits, neck, and other large blood vessels of the feverish patient to cool down. Pay attention to avoid direct contact with the ice to prevent frostbite. - Ice cap cooling: It can cool the head. For example, wearing an ice cap on the head can prevent cerebral edema, reduce brain cell metabolism, and improve the tolerance of brain cells to oxygen deficiency. 3. Room temperature adjustment: Maintain the room temperature at around 25°C. At the same time, maintain appropriate ventilation in the room to help the patient dissipate heat and cool down.

There were many ways to cool down the phone: - ** In terms of hardware **: - Some mobile phones used water-cooling technology to cool down, which was to design a water-cooled heat dissipation pipe on the CPU heat sink, which was fully integrated with the graphene heat sink parallel to the main board to conduct the CPU heat to the outer casing. - You can use professional phone cooling back clips, metal cooling supports, and other accessories to help the phone dissipate heat with the help of thermal and thermal principles. For example, the Nishen water cooler could be directly attached to the phone or fixed to the phone through a clip. It could cool down 45 degrees in 46 seconds, and the temperature could be adjusted freely. It was suitable for Apple and Android phones. - ** Software **: - Some phones had their own cooling function, such as the Vivo phone, which could wake up the small V. The voice input could also shorten the automatic lock screen time to 30 seconds and click a button to cool down. - There were special cooling applications for mobile phones, such as Coolify, which used unique technology to reduce the heat generated by the system and help keep the phone temperature in the normal range. However, the effect may vary according to individual usage and device model. - He could reduce the heat of the phone through software optimization, such as turning on low-battery mode or automatically adjusting screen brightness to reduce the power consumption of core components such as CPU and CPU, and turning off unnecessary background applications to avoid excessive resource consumption. - ** Usage Habits **: - You can perform one-click power-saving optimization, that is, click on the settings-battery-one-click power-saving, detect the phone status and manually select the optimization item according to the prompt; or directly turn on the power-saving mode or super power-saving mode to reduce power consumption and heat, but it may affect the user experience. - During daily use, don't play with your phone while charging, clean up unused background applications in time, don't play music and videos at a high volume for a long time, and try to avoid surfing the Internet in places with poor signal. - ** Regarding environmental conditioning **: Move the phone to a cool and well-vented environment, such as indoors, in a cool place, or use cooling equipment such as a small fan. Do not place it in direct sunlight or in a confined space. The phone itself also had an automatic temperature control function. When it detected that the internal temperature was too high, it would automatically reduce the frequency and screen brightness to protect the phone hardware.

There were many ways to lower the temperature physically. The first method was to replenish fluids and drink warm water. This was a more effective method. The second method was wet compress. A wet towel could be placed on the forehead, wrists, and calves, and other parts could be covered with clothes. The third method was the rubbing bath method. For example, the warm water rubbing bath at 38 - 40 ° C had an obvious cooling effect. It could also use alcohol rubbing bath and Chinese medicine rubbing bath. The rubbing bath site could choose the distribution area of the human body's large blood vessels, such as the head, armpits, neck, etc. The fourth was ice compress cooling method, including ice bag cooling, ice cap cooling, such as wrapping ice cubes with towels to cool down the armpits, neck and other large blood vessels of patients with fever. Pay attention to avoid direct contact with the skin to avoid frostbite; You can also use physical cooling headband cold compress (put the headband into the freezer of the refrigerator to freeze before use). The fifth was to adjust the indoor temperature. It was recommended that the room temperature should not exceed 20 ° C, and at the same time, maintain moderate ventilation in the room. Sixth, reduce the patient's clothing and do not lower the patient's temperature by covering his sweat. Seventh, for children, when they have a low fever, they can take a warm bath of about 34 - 36 ° C (2 - 3 ° C lower than the child's body temperature) for about 15 minutes. During this period, close the doors and windows to avoid direct wind or breeze. Eight, you can give the child more hot water, wash his feet with warm water, rub his hands and feet hot, put an ice water pillow under his head and neck, use a towel to apply cold compress on his head, paste a fever paste on his forehead, and so on. However, physical cooling is not recommended for infants and patients with blood diseases. If physical cooling cannot bring the body temperature down to normal in a short period of time, it is recommended to go to the hospital in time to avoid delaying the illness. In the process of physical cooling, there may be local frostbite, diarrhea, cardiac arrest, general reactions, subcuticular bleeding, local pressure sores, alcohol allergy, chemical cooling bag fluid extravasation and skin damage, etc., which should be treated according to the specific symptoms.

Physical cooling methods included: 1. [Replenish Fluid: Drinking warm water is an effective physical cooling method.] 2. ** wet compress **: Place a wet towel on your forehead, wrists, and calves, and cover the rest of your body with clothes. 3. ** Wiping bath method **: - ** Warm water scrub bath **: The cooling effect of 38 - 40 ° C warm water scrub bath is obviously higher than that of the traditional 27 - 37 ° C warm water scrub bath method. The water temperature is slightly higher than the body surface temperature. After the scrub bath and massage cause the blood vessels to expand, it can achieve the purpose of cooling down through heat dissipation. It is better to apply it during the peak fever period or when the fever is below 38.5 ° C, and when the surgery absorbs heat. - ** Alcohol scrub bath **: The cooling efficiency of 41 - 43 ° C alcohol scrub bath is obviously better than that of 28 - 32 ° C alcohol scrub bath. However, when used by children, it is easy to cause blood circulation and blood volume to decrease, resulting in collapse. Infants under 3 years old are generally not suitable for alcohol scrub bath. Drinking hot drinks before the scrub bath can reduce discomfort. - ** Traditional Chinese medicine bath ** 4. ** Ice compress cooling method **: - ** Ice bag cooling **: For example, an ordinary ice bag was added with 30% to 40% of the total capacity of the infusion bag. After being placed in the refrigerator and frozen, it would be in the shape of a smoothie. It could be used repeatedly, and it was soft and not easy to coagulate. It could fully contact the patient's body surface. When the 10% saltwater ice pack was used in an environment of 18 - 24 ° C for 3 hours, the temperature was still-5 ° C. The low temperature lasted for a long time. During the melting process, it was mixed with frost and ice. The ice pack was soft and could fully contact with the body surface. It was easy to fix and was better than water ice to cool down. It could also be sewn into a cloth bag, filled with millet to 1/2, frozen, and directly applied to the body surface to cool down. It was not easy to cause local frostbite, had strong application ability, and did not affect the change of body position. When using it, pay attention to wrapping the ice with a towel to cool down the armpits, neck and other large blood vessels of patients with fever, so as to avoid frostbite caused by direct contact with the skin. - ** Ice cap cooling down ** 5. ** Venous cooling method ** 6. ** Enemas ** 7. ** Medical ice blanket cooling method **. 8. ** Physical cooling headband **: For cold compress, put the headband into the freezer of the refrigerator to freeze it; for hot compress, put the headband into the microwave oven (high temperature). The heating time is 100 seconds for each use. If it is used continuously, the second heating time is within 60 seconds. 9. ** Others **: For example, don't cover the sweat of the patient with fever, adjust the indoor temperature (do not exceed 20 ° C and maintain ventilation), wear less clothes, wash the child's feet with warm water, rub the child's hands and feet to warm up, put an ice water pillow under the head and neck, and put a fever reduction paste on the forehead.

The reverse rotation of the crown cooling fan may be due to the reverse connection of the starting winding of the fan motor. It can be solved by swapping the two connections of the starting winding. The fan had a main winding and a secondary winding, and the capacity could change the degree of the magnetic field, causing the phase difference between the main winding and the secondary winding to differ by a certain degree. If the main winding lagged behind the secondary winding by a certain degree, the motor would reverse. It could also be solved by changing the connection of the voltage or finding a dual-control switch. The two ends of the terminal were connected to one end of the main winding and one end of the auxiliary winding, and the central contact of the dual-control switch was connected to the power line. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
