- Educational video describing the condition of hypothermia.
Hypothermia is a life threatening condition that may result in death. A drop in the core body temperature of less than 95 degrees F (35 degrees C). this temperature is below what is required for normal metabolism and bodily function. The normal body temperature is between 97.7-99.5 degree Fahrenheit (F) which is the same as 36.5-37.5 degrees celsius (C). The body’s thermoregulation mechanism adjusts to weather changes.
During extreme cold, the body receives a signal from sensory receptors. The signal will go up to the brain. The brain then sends a signal to the body to respond to the col temperatures and attempts to maintain the core body temperature. This is necessary in order to provide the vital organs with the necessary heat to function properly. The brain will send a signal to the smooth muscle cells of the blood vessels of the skin and the skeletal muscles.
During the cold, the signal from the brain causes vasoconstriction of the arterioles in the skin which allows the body to shift the blood to more vital areas f the body. Another signal from the brain goes to the skeletal muscles which quickly contracts them causing shivering that helps to keep the body warm. If the body is exposed to cold and the thermoregulation mechanism is unable to preserve the heat, a drop in the core body temperature will occur. As the body temperature drops, characteristic symptoms will occur such as shivering and mental confusion.
Hypothermia can be mild, moderate, severe or profound. Heat is produced by the muscles, by the heart, as well as the liver and the body loses heat through the skin. The body heat increases 2-4 times more with contraction of the muscles from exercises or by shivering. Accurate core body temperature can be measured by a special low body temperature thermometer. Hypothermia may also be associated with frostbite.
Symptoms of hypothermia: depends on the degree of hypothermia:
•Shivering •Blushed lips and extremities
•Altered mental status due to decreased CNS electrical activity: such as confusion, poor judgment, etc.
•Slowly the patient may lapse into an unconscious state.
•Cold hands, feet or skin, shivering and teeth chattering or feeling cold does not necessarily mean you are experiencing hypothermia. Only a core body temperature below 95 degrees F indicates hypothermia.
Causes of hypothermia include:
•Exposure to low temperatures •Alcohol use during exposure to cold. •Poor clothing •Trauma
•Swimming or diving into cold water: heat is lost more in water than on land.
•A patient who perform outdoor sports such as skiing or mountain climbing.
•Patients who have had a major surgery
•Excessive blood and fluid loss. Alcohol consumption increase the risk of developing hypothermia ad does not help with the symptoms. Alcohol is a vasodilator and it increase the blood flow to the skin and extremities. Alcohol may make the patient feel warmer, however it increase the heat loss by vasodilation.
•Elderly people are most prone to hypothermia since they are more fragile, lower in body fat content, are prone to worse outcome if they have cardiac history. Keep elderly individuals home and warm.
•Children are also susceptible to hypothermia. Children have a smaller size and less body surface area. A child’s head is larger relative to the rest of their body and a lot of heat is lost through their heads. When outside in the cold, make sure to cover the heads of children.
•Paradoxical undressing: a large percentage of deaths occurs from hypothermia when the patient becomes confused and disoriented, they may remove their own clothing thinking they will feel better. When this occurs it only increases the rate of heat loss and the condition of hypothermia gets worse. The heart rate may slow in patients with hypothermia. It may be difficult to find a pulse, so keep trying. Hypothermia increases the heart’s need for oxygen and lethal cardiac arrhythmia may occur.
Hyperthermia is different from hypothermia. Hyperthermia occurs due to elevated body temperature that is present during heat exhaustion and heat strokes.
Treatment
•Immediate action is required •Move the patient from water and to a safe place. •Remove the wet clothing and wrap the patient with a warm, dry blanket. •Do not massage the patient •Do not apply dry heat •Warming of the patient should be done gradually.
Treatment at the hospital or in the field
•Usually begin with warm blankets •Warm IV fluids •Warm humidified oxygen •EKG •Blood warmer
Conclusion
•Any drop in body temperature will make a person feel cold.
•If you begin to shiver during exposure to cold, this is the point where you should get out of the weather and warm up.
•Prolonged exposure to cold beyond this point can be dangerous and it is not a good idea to remain exposed to these cold temperatures.

I was found with a core tempature of °81 F, °27.2 C.. I was covering my body in snow to try to "cover up" from the -16 weather here in Minnesota.... honestly remember most that it was a peaceful feeling to just drift off.
Thank God your ok
Holy

Honestly covering up in that snow might’ve helped you out (unless you were naked) as an insulator. Good on you for getting out of that alive. Just going down to 89-91 degrees made me surprisingly drowsy and mentally slow.
81 Fahrenheit is a dangerously low temperature for a human, that is a sign of severe hypothermia
ive had hypothermia this year in march, got it during a school trip. We went tobaggoning in an indoor snowdome. I only wore a black hoodie with grey warm trousers and trainers. we had three turns each. Third time, I crashed into glass wall while in tobaggon and I filpped twice and fell unconscious csuse I remember hitting my head twice. I woke up with the tobaggon on me and my hands were bruised. my entire body was cold even when we were on the bus. the teacher told me , my body was freezing. I went home and told my mum everything and she gave me hot chocolate and wrapped me in blankets and gave me a mini heater. I went doctors the next day because my head was still hurting and the teachers told me too go just incase, the hyperthermia had gone. I wemt doctors and they told me that I had a mild concussion
*hypothermia
@@JessicaHuangTheQuetzalKirin relax he just had a concussion.
Oh... I hope you're okay
The hypothermia may have actually lessoned the effects from your concussion. Cold has a protective effect on the brain. You are *very* lucky.
I got mild hypothermia this morning and recovered by sharing body heat and keeping my body warm.
i got it all last night and still recovering. once u warm up and go outside u realize how cold it actually is and its terrifying to even think about. i was out in 16 degree weather for 8 hours, at some point i took my socks and shoes off bc i thought that would make my feet warmer.
I froze to death in 1994. After losing control on an icy road, I hit my head on my car windshield sustaining a subarachnoid hemorrhage. I left the car, not understanding the extent of my injuries. Honestly it wasn't super cold, (just below freezing,) so I only had on a windbreaker. I left the car, and got lost trying to find help. I passed out from my concussion in the snow. I laid there for 6 hours. The state police did a poor search of the area, and had my car towed. When someone found me the next morning I was blue and lifeless, but still alive. They called 911, and a life flight helicopter was dispatched. Ground crew took my vitals, that said I was 20 degrees celsius (68 degrees Fahrenheit), was dead, and waived the copter off. A technician claims he then felt a pulse. I don't know if he did, or if he was just taking a chance on me, and they tried to get the copter to return. Still after it goes, it can't come back. So they had an ambulance be dispatched. I was definitely w/o a pulse when it arrived. They rushed me to a trauma unit, and tried to hook me up to a blood rewarming machine. Unfortunately the device was caked with dried old blood. So instead they gave me 100 blood transfusions, and brought me back. About a half an hour had passed. So not only had I had the hemorrhage, but I also suffered extreme hypoxia . I was placed into a month long drug induced coma, and my family was told to expect the worst. The effects of hypoxia are similar to a stroke. Healing is a lifelong process, and never ends. Improvements happen slower today, but still occur. The cold was a double edged sword. It killed me, bu also helped protect my brain from a more severe kind of injury.
Thanks! I really need this for my speaking grade to present to the class in 6th grade!
This is extremely useful, I would love to become an emergency doctor or a paramedic when I grow up, when I’m old enough I will get involved in kidet. For now I’m just doing lemme research
Being a paramedic is ass and doesn’t pay well. I’d rather become a nurse before becoming a paramedic.
I'm studying paramedic
I've had hypothermia bc I got pissed off and went walking in temps in the lower 40's-upper 30's without my coat.wasnt a great idea by the time I decided to call my mom my body temperature was 95°f and that was after being in the car with the heater on full blast for a solid 10-15minutes!
Its 3am and I randomly got obsessed with hypothermia (I live in the southwest)
Thank u so much I have hypothermia right now and I was so delusional last night it scared me I thought I was going crazy you made me feel a lot better
Ngl this was disturbing, but I need to for a wattpad book so...
This a great reminder for the super cold blast like -20 * degrees and be lower more than -20* or the wind chills - 30* degrees. In winter places
Thanks a lot for this video! Very laconic, clear and understandable presentation!
I was walking on a pathway to get food while at a school lunch break and it was 30 degrees celsius and i ended getting stage 3 hypothermia. It was really scary.
Thank you, Dr. Ebraheim. I used your video to introduce a story by Jack London. The main character traveled through the Yukon and experienced hypothermia.
Very Informative and interesting video.
Great video! clear and concise.. Is there one for hyperthermia?
Thanks for great information
I feel strange saying this, but I have a lower than average body temperature and heart-rate. If I suffered from hypothermia, would the parametres of it move down or do I just have a smaller window to be cold?
Eat more garlic
That's a really good question...
You state in your video "Children have a smaller size and less body surface area." Chidren have a proportionally larger BSA not smaller.
would you mind clarifying whether we can give warm drinks or hot drinks to moderate hypothermic patient or a severe hypothermic patient? Is it warm or hot or NONE at all? There is a huge body of conflicting information on this subject on the internet. No fluid, warm fluid, or hot fluid. Definitely not coffee as it is a vasodilator.
In the Andes Mountains I've seen people give warm milk but only when they are concious and somewhat coherent. Don't give them alcohol tho, I've seen people give Aguardiente and that's a terrible mistake.
this literal saved my life. i faint like 2 times before my parents found me all blue
It was so cold when I slept I think I got this
I don't have muscles mass only recently i have a hub of chunky fat skin layer that were made to be like obesity ir overweight. My bed is invisibly infused to aircon so to perssive as cold room
There was a stupid community pool party thing I went and when swimming the pool wasn't heated so I got so cold I got out wrapped myself in my towel and couldn't stop shivering I was trying to put on a jumper properly my lips were grey even an hour later. It was horrible soz if I don't make sense it happened an hour or two ago......
good introduction
I have hypothermia when I waited in the cold at my school
Iam 25 years old, but my mom told me when i was baby i drop from bed during that moment she found me on the bed hiding under my mom said like 1 meters to ground and she said i dont cry that time and donw have money to she docter chech my head. Turn out when i was 12 years old when i run and my back sweat some times i can’t breathe good they thought me got asma, but right now when i was super cardio badminton my back feel cold and i cant sleep by heartrate goiing up when i take sleep it makes me find this hypoterima. What’s should i do?
My body temps are betweem 94.9-97f is this normal?
Yes
I have hypothermia this morning...and it's happen a few time..
My natural body temperature is 90-91° F... Kids am I normal?
Can't find it ANYWHERE! Everywhere they just talk about the temporary "because of cold weather or wet clothes or blah blah" and nowhere about having permanent low temperature without some temporary mentioned reasons.
you are an android XD lol im kidding, you must go to the doctor for a checking, maybe you are taking your temperature the wrong way or you can have a failure in your hypotalamus
I'm watching this video because in Pakistan, 21 people died of hypothermia today.
Kenneka Jenkins was drunking alcohol 🍷 and she died in the freezer so when was in the freezer as being drunk 😵 hypothermia happened
It’s funny how sometimes alcohol can increase risk of hypothermia and sometimes it can decrease it.
Im in Minnesota is it possible to ctb by hypothermia
my mum has rhemutoid arthritis
Eating in all meat carnivore diet has been proven to cure autoimmune disseases.
So to check if you have it, you can rip of your nail and if you bleed your fine and if it doesn't that means you have hypothermia
Not sure thats the smartest idea
@@jakesparrow5961 yeah...
Energy drinks can helpful or danger for hypothermia patient...???????
danger. they would stress out even more the poor body
Alcohol can sometimes be helpful for them and sometimes it can be dangerous for them.
God and I'm jumping in an ice lake today??
How many abandoned soul's die from this every winter? Shouldn't you people be feeding...clothing...and taking these people out of danger? No I did not say "take them into bondage" or cage them.
I swim in salt %35 salty water 24° river for 15 minutes in showered for 1 minute. Walk for about 15 minutes in 24 degrees air, than swim again for 5 minutes. And shower 18° shower for 1 minute. And dried up after 10 minutes.
All in 60 minutes. I did not shivered, my tits got very sensitive., never felt that way before. I thought if i stay in water and expose to wind , and wet short, i would probably would get hypotermia, and get hurt in legs and chest. No pain is worth in water. My hand got red when I squeeze, make a fist. Explains the blood moving close to my skin.
👍👍👌
Om dying of stress
Who discovered Hypothermia ???
Jake Sparrow I suffered hypothermia
@@alicewong7206 were you shivering?
@@alicewong7206 same
Just drink a bottle of whiskey 🥃 and u be fine people.
alcohol causes vasodilation and you will lose even faster temperature, so NO.
Study me
