Body Temperature01:25

Body Temperature

3.7K
The body's temperature, measured in degrees, is determined by the balance between heat production and dissipation to the surrounding environment. For instance, if exercising vigorously, the body will produce more heat, causing sweat and dissipating that heat. Despite extreme environmental conditions and physical exertion, the human temperature-control system maintains a constant core body temperature (the temperature of deep tissues, which are the tissues located beneath the skin and other...

As a nurse, it is vital to understand the factors affecting body temperature to monitor variations and effectively evaluate deviations from regular.

Increased Body Temperature

6.4K
A body temperature above  38°C  (100.4 °F) is known as fever or pyrexia, and a person with fever is termed 'febrile.' Typically, the hypothalamus, a part of the brain that acts as the body's thermostat, regulates body temperature through a thermoregulatory setpoint. It receives signals from cold and warm thermal receptors throughout the body and adjusts the body's temperature accordingly. Fever occurs when this hypothalamic setpoint is altered, usually in...

Methods of reducing fever01:22

Methods of reducing fever

1.6K
The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.

Decreased Body Temperature01:29

Decreased Body Temperature

1.2K
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...

Homeostatic Imbalances in Body Temperature01:19

Homeostatic Imbalances in Body Temperature

3.9K
Hyperthermia occurs when the body's temperature becomes unusually high, often due to heat exposure, intense physical activity, or certain illnesses. This condition can create a dangerous cycle where elevated body temperature increases the metabolic rate, generating more heat and potentially leading to organ failure and brain damage. A severe form of hyperthermia, called heat stroke, can raise body temperature to life-threatening levels. Fever, on the other hand, is a controlled form of...

    Summary

    Hypothermia, a dangerous drop in body temperature, is often missed due to poor measurement tools. This review covers its causes, effects, and new core rewarming treatments.

    Area of Science:

    • Medical Science
    • Physiology
    • Emergency Medicine

    Background:

    • Hypothermia (core temperature <35°C) is often unrecognized.
    • Standard thermometers are inadequate for accurate measurement.
    • Multiple causes and complex pathophysiology hinder diagnosis and treatment.

    Purpose of the Study:

    • To review the pathophysiology, etiology, and management of hypothermia.
    • To highlight the importance of understanding thermoregulation.
    • To discuss recent advances in core rewarming therapy.

    Main Methods:

    • Literature review of hypothermia.
    • Analysis of thermoregulation physiology.
    • Examination of diagnostic and treatment strategies.

    Main Results:

    • Hypothermia diagnosis is challenging due to inadequate tools and complex presentation.
    • Understanding thermoregulation is crucial for effective management.
    • Core rewarming represents a significant advancement in hypothermia treatment.

    Conclusions:

    • Accurate recognition and management of hypothermia are critical.
    • Further research into thermoregulation and treatment is warranted.
    • Improved diagnostic methods and therapeutic approaches are needed.
