0 00:00:00.000 --> 00:00:03.025 COVID-19 2 1 00:00:03.025 --> 00:00:07.225 Flying Doctors Korea Crisis Education - COVID-19 #Response Methods Next, we will briefly explain the response methods 2 00:00:07.225 --> 00:00:13.625 If you suspect that you have been infected with COVID-19 or have received a confirmed diagnosis, 3 00:00:13.625 --> 00:00:16.126 isolation is the most important aspect 4 00:00:16.126 --> 00:00:20.076 #Response Methods - Hydration and Nutrition Next, it is important to pay attention to hydration and nutrition 5 00:00:20.076 --> 00:00:25.226 (10% increase in fluid intake when body temperature increases by 1 degree Celsius from normal) In the case of fluid intake, if our body temperature increases by 1 degree Celsius from normal, 6 00:00:25.226 --> 00:00:32.976 fluid consumption increases by 10%, so if we consume fluids as usual when we have a fever, 7 00:00:32.976 --> 00:00:35.826 dehydration symptoms inevitably occur 8 00:00:35.826 --> 00:00:39.076 Dehydration symptoms are actually very dangerous 9 00:00:39.076 --> 00:00:41.026 Next, nutrition intake is important 10 00:00:41.026 --> 00:00:47.277 If we do not properly intake nutrients, we will not have the energy to overcome the stress of infection 11 00:00:47.277 --> 00:00:52.927 (The regeneration time of intestinal epithelial cells is long, which prolongs the recovery period of the disease) When diarrhea or vomiting occurs, the regeneration time of intestinal epithelial cells is long 12 00:00:52.927 --> 00:00:55.977 Which will prolong the recovery period of the disease 13 00:00:55.977 --> 00:01:01.127 Therefore, you should pay strong attention to your intake of fluids and nutrients 14 00:01:01.127 --> 00:01:08.127 #Response - Taking fever reducers Taking fever reducers is important, and when it comes to fever reducers, there is ibuprofen, or Advil in other countries 15 00:01:08.127 --> 00:01:10.578 In Korea, there is Carol and so on 16 00:01:10.578 --> 00:01:15.028 If you don't have acetaminophen like Tylenol, you can take aspirin 17 00:01:15.028 --> 00:01:20.678 Because, as explained earlier, if the fever persists, you become vulnerable to dehydration 18 00:01:20.678 --> 00:01:25.128 When we have pain, fever, or feel unwell 19 00:01:25.128 --> 00:01:28.878 It causes stress and that can also weaken the immune system 20 00:01:28.878 --> 00:01:33.178 Therefore, it is important to take sufficient fever and pain relievers 21 00:01:33.178 --> 00:01:37.429 #Response - Dealing with shortness of breath, chest pain, and decreased urine output If you have any of these three symptoms, you should definitely go to the hospital 22 00:01:37.429 --> 00:01:41.979 Typical symptoms would be shortness of breath, chest pain, and decreased urine output 23 00:01:41.979 --> 00:01:44.579 #Response - Dealing with shortness of breath Shortness of breath is a very subjective symptom 24 00:01:44.579 --> 00:01:50.679 For example, I may not have been out of breath climbing two flights of stairs before 25 00:01:50.679 --> 00:01:56.479 But suddenly, I find myself out of breath after walking just a little, or even after climbing just one flight of stairs 26 00:01:56.479 --> 00:01:59.979 If you experience difficulty breathing, you need to go to the hospital 27 00:01:59.979 --> 00:02:07.780 And if you have come down with a lung disease or, although rare, myocarditis or myocardial infarction, chest pain may accompany it 28 00:02:07.780 --> 00:02:11.380 In such cases, you must go to the hospital and see a doctor 29 00:02:11.380 --> 00:02:18.080 #Response method - Decreased urine volume. If dehydration has progressed or there is kidney damage due to medication, urine volume may decrease 30 00:02:18.080 --> 00:02:23.030 When you have these three symptoms, it's best to go to the hospital as soon as possible 31 00:02:23.030 --> 00:02:26.180 #Routes of Transmission Next, let me briefly explain about the routes of transmission 32 00:02:26.180 --> 00:02:31.880 We need to know the routes of transmission of COVID-19 to know how to defend against it 33 00:02:31.880 --> 00:02:36.431 Size comparison (Coronavirus: 0.1㎛ / Droplets (mucus): 5㎛ or more → up to 8m) The coronavirus is about 0.1㎛ in size 34 00:02:36.431 --> 00:02:42.481 If converted to meters, it is one ten millionth of a meter, it is a very small virus 35 00:02:42.481 --> 00:02:49.681 The most common route of transmission for the coronavirus is through droplets, also known a drops of saliva 36 00:02:49.681 --> 00:02:54.231 Droplets is defined as saliva drops that are 5㎛ or larger 37 00:02:54.231 --> 00:03:02.382 When speaking or breathing quietly like me, it only goes up to a radius of 2 meters and falls to the ground due to gravity 38 00:03:02.382 --> 00:03:07.082 However, if you shout, sneeze, cough, or sing, 39 00:03:07.082 --> 00:03:11.932 It is known that these droplets can spread up to a maximum of 8 meters 40 00:03:11.932 --> 00:03:17.932 However, as these droplets fly, the moisture evaporates 41 00:03:17.932 --> 00:03:25.482 As a result, the droplets become smaller and lighter, and when they become smaller than 5㎛, 42 00:03:25.482 --> 00:03:27.982 (Aerosol: 5㎛ (0.6~0.8㎛) → floats in the air for more than 16 hours) This changes from droplets to aerosols 43 00:03:27.982 --> 00:03:35.683 Aerosols are lightweight and can float in the air for more than 16 hours without being affected by gravity 44 00:03:35.683 --> 00:03:41.783 Aerosols can also spread throughout a building through the air conditioning system 45 00:03:41.783 --> 00:03:46.583 They can also be present in the space we are in without being visible 46 00:03:46.583 --> 00:03:50.083 These droplets and aerosols can spread not only in the immediate vicinity 47 00:03:50.083 --> 00:03:56.534 But can also travel far and act as a source of contact transmission 48 00:03:56.534 --> 00:04:02.584 That's why we need to understand why wearing a mask and washing hands are important 49 00:04:02.584 --> 00:04:08.134 For example, aerosols can be as small as 0.6 micrometers 50 00:04:08.134 --> 00:04:11.334 So, we need to know the performance of the masks we are using 51 00:04:11.334 --> 00:04:16.584 For example, an N95 mask filters out 95% of particles as small as 0.3 micrometers 52 00:04:16.584 --> 00:04:22.884 A KF94 mask can block 94% of particles as small as 0.4 micrometers 53 00:04:22.884 --> 00:04:28.585 And a KF80 mask, commonly known as dental mask, can block 80% of particles as small as 0.6 micrometers 54 00:04:28.585 --> 00:04:35.135 Surgical and regular masks can filter out particles as large as 3 micrometers, but the percentage is not specified 55 00:04:35.135 --> 00:04:42.535 Hand washing is important because droplets and aerosols can spread far and wide 56 00:04:42.535 --> 00:04:45.485 (Fomites) non-living contact infection agent -> Wash hands, disinfect, eat cooked food) There could be viruses on any object around us 57 00:04:45.485 --> 00:04:51.285 Therefore, washing hands is very important, disinfection is important, and eating cooked food is important 58 00:04:51.285 --> 00:04:54.261 Thank you
