Increased Body Temperature01:25

Increased Body Temperature

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 response to an infection or illness.
Factors Affecting Body Temperature01:28

Factors Affecting Body Temperature

As a nurse, it is vital to understand the factors affecting body temperature to monitor variations and effectively evaluate deviations from regular.
Factors may  include:
Homeostatic Imbalances in Body Temperature01:19

Homeostatic Imbalances in Body Temperature

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...
Methods of reducing fever01:22

Methods of reducing fever

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.
Pharmacological Methods of Reducing Fever:
Decreased Body Temperature01:29

Decreased Body Temperature

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 sustained extreme cold exposure, and severe...
Assessing Body Temperature - Temporal Artery01:19

Assessing Body Temperature - Temporal Artery

Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.  
Step 3: Assess the patient's forehead...

Summary

Heatwaves significantly increased mortality in Vienna, particularly among the elderly. Preventive measures are crucial as global warming intensifies heatwave risks.

Area of Science:

  • Environmental Health
  • Public Health
  • Epidemiology

Background:

  • European heatwaves in 2003 caused increased mortality, but Austrian data were lacking.
  • Vienna experienced rising seasonal temperatures over 35 years.
  • This study addresses the impact of heatwaves on mortality in Vienna.

Purpose of the Study:

  • To analyze the association between heatwaves and daily mortality in Vienna.
  • To quantify the excess mortality attributable to heatwaves.
  • To identify vulnerable populations during heatwave events.

Main Methods:

  • Utilized daily mortality data (1998-2004) and meteorological data for Vienna.
  • Defined heatwaves using the Kysely criterion.
  • Employed a generalized additive model to predict daily mortality, accounting for seasonal trends and heatwave days.

Main Results:

  • Vienna saw an increase of over 1.7°C in seasonal temperatures over 35 years.
  • In 2003, 44 heatwave days were associated with approximately 180 excess deaths.
  • Heatwave days (1998-2004) showed a significant 1.13 relative mortality risk, higher in females and the elderly (>65 years).

Conclusions:

  • Heatwaves demonstrably impacted Vienna's mortality, though less severely than in other European regions.
  • An estimated 130 deaths in 2003 could have been prevented with timely medical aid and advice.
  • Preventive strategies targeting the elderly are essential due to increasing heatwave frequency linked to global warming.
