Heat syncope is fainting or dizziness as a result of overheating (syncope is the medical term for fainting). It is a type of heat illness. The basic symptom of heat syncope is fainting, with or without mental confusion. [1] Heat syncope is caused by peripheral vessel dilation, resulting in diminished blood flow to the brain and dehydration.
Other signs and symptoms vary. Accompanying dehydration can produce nausea, vomiting, headaches, and low blood pressure and the latter can lead to fainting or dizziness, especially if the standing position is assumed quickly. In severe heat stroke, confusion and aggressive behavior may be observed.
Overheating is a phenomenon of rising temperatures in an electrical circuit. Overheating causes damage to the circuit components and can cause fire, explosion, and injury. Damage caused by overheating is usually irreversible; the only way to repair it is to replace some components.
Blood pressure is recorded as two readings: a higher systolic pressure, which occurs during the maximal contraction of the heart, and the lower diastolic or resting pressure. [11] In adults, a normal blood pressure is 120/80, with 120 being the systolic and 80 being the diastolic reading. [12] Usually, the blood pressure is read from the left ...
Ice and water are poured in, and the bag is zipped, with one arm hanging out so Willens can monitor the patient's blood pressure. This impromptu ice bath allows the patient to cool down rapidly ...
Heat stress can result in heat-related illnesses, such as heat stroke, hyperthermia, heat exhaustion, heat cramps, heat rashes, and chronic kidney disease (CKD). [2] [3] Although heat exhaustion is less severe, heat stroke is a medical emergency and requires emergency treatment, which if not provided, can lead to death. [4]
However, experts say it's possible to use electric space heaters safely. If your model is new, is in good working condition, has safety features like automatic shut-off in case of overheating or ...
In heat syncope, or exercise-associated collapse, there is an increased dilation of blood vessels near the skin's surface and a pooling of blood in the lower extremities due to a decrease in vasomotor tone, which is the extent of control over the constriction and dilation of blood vessels. This results in a drop in blood pressure when not lying ...
