Hypothermia

#hypothermia, #cold-related illness, #cold wave, #body temperature, #core temperature, #frostbite, #winter health, #hand tremor, #body tremor

Hypothermia refers to a drop in core body temperature to 35°C or below. The lower the body temperature falls, the more dangerous the condition becomes, and in severe cases it can lead to cardiac arrest. It can occur with prolonged exposure to extreme cold or cold environments, and extra caution is needed when alcohol has been consumed. If hypothermia is suspected, please call 119 immediately or go to a hospital.

Even without symptoms, it is important to detect it early through regular health checkups. If an abnormal finding is detected or you have any concerns, please be sure to consult a medical specialist.

#lower extremity arterial disease, #peripheral arterial disease, #peripheral vascular disease, #leg pain, #atherosclerosis, #limb ischemia, #diabetic foot, #numbness in the hands and feet, #arm numbness, #tingling in the legs

Lower extremity arterial disease occurs when the arteries supplying blood to the legs become narrowed or blocked, reducing blood flow and causing symptoms such as pain, numbness, and delayed wound healing.

Peripheral vascular disease is a condition in which the blood vessels in the legs, far from the heart, become narrowed or blocked by blood clots (thrombi), and it can be a medical emergency. In serious cases, tissue in the leg can die and amputation may be necessary, so if your leg is severely swollen and painful, please consult a cardiology or vascular specialist immediately.

More than 50% of people with pneumonia and more than 90% of people who die of pneumonia are aged 65 or older. In older adults, symptoms are often not obvious, so diagnosis is easily delayed. If you have suspected symptoms, please consult a pulmonology and allergy specialist immediately.

Post-Cardiac Arrest Integrated Care

#cardiac arrest, #cardiopulmonary resuscitation, #defibrillation, #chain of survival, #targeted temperature management, #heart, #emergency

Cardiac arrest is a condition in which the heart stops, cutting off the blood supply to the brain and the rest of the body. Without emergency care within 3 to 5 minutes, serious brain damage can occur, so immediate treatment such as CPR and defibrillation is important, and integrated care by a specialized medical team is needed afterward. If cardiac arrest is suspected, call 119 immediately and receive treatment from a medical specialist.
