Hypothermia is the cause of at least 1,500 deaths a year in the United States. [2] It is more common in older people and males. [ 5 ] One of the lowest documented body temperatures from which someone with accidental hypothermia has survived is 12.7 °C (54.9 °F) in a 2-year-old boy from Poland named Adam. [ 6 ]
Causes: Exposure to cold temperatures [6] Risk factors: Military occupation, recreational winter activities, homelessness, inadequate or wet clothing, substance abuse, diabetes, peripheral vascular disease [6] [7] Diagnostic method: Based on symptoms [1] [6] Differential diagnosis: Hypothermia, Raynaud's phenomenon, chilblains (pernio), cold ...
Symptoms include bluish skin, dilated pupils, slowed pulse and breathing, low blood pressure and loss of consciousness. In severe cases, a person’s heart can stop beating, and they may require CPR.
[1] [2] Patients observe these symptoms and seek medical advice from healthcare professionals. Because most people are not diagnostically trained or knowledgeable, they typically describe their symptoms in layman's terms, rather than using specific medical terminology. This list is not exhaustive.
The cold water can cause heart attack due to severe vasoconstriction, [2] where the heart has to work harder to pump the same volume of blood throughout the arteries. For people with pre-existing cardiovascular disease , the additional workload can result in myocardial infarction and/or acute heart failure , which ultimately may lead to a ...
Symptoms: Numbness, feeling cold, clumsiness, pale color [1] Complications: Hypothermia, compartment syndrome [2] [1] Types: Superficial, deep [2] Causes: Temperatures below freezing [1] Risk factors: Alcohol, smoking, mental health problems, certain medications, prior cold injury [1] Diagnostic method: Based on symptoms [3] Differential diagnosis
The U.S. Centers for Disease Control and Prevention warns that hypothermia, which can be fatal, is most likely at very cold temperatures, but can happen at cooler temperatures above 40 degrees (4. ...
The resulting increase in calcium concentrations within the cells cause the muscle fibers to contract. [1] This generates excessive heat and results in metabolic acidosis. [1] Diagnosis is based on symptoms in the appropriate situation. [2] Family members may be tested to see if they are susceptible by muscle biopsy or genetic testing. [4]
