Decreased Body Temperature01:29

Decreased Body Temperature

954
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...

Requirements for Human Life

12.4K
The Earth and its atmosphere have provided humans with air, water, and food, but these are not the only requirements for survival. Humans also require a specific range of temperature and pressure that the Earth and its atmosphere provides.
Oxygen
Atmospheric air is only about 20 percent oxygen, but that oxygen is a key component of the chemical reactions that keep the body alive, including the reactions that produce ATP. Brain cells are susceptible to a lack of oxygen because they require a...

Summary

Cold urticaria (CU) is a rare condition that can be dangerous for divers. This case highlights why CU should disqualify individuals from diving due to the risk of anaphylaxis.

Area of Science:

  • Diving Medicine
  • Dermatology
  • Allergology

Background:

  • Cold urticaria (CU) is an uncommon condition presenting with hives upon cold exposure.
  • A 39-year-old scientific diver developed CU postpartum and sought to resume diving.
  • Evaluation for underlying causes and management strategies were initiated.

Purpose of the Study:

  • To present a case of cold urticaria in a scientific diver.
  • To discuss the implications of CU for diving safety.
  • To highlight CU as a potential disqualifying condition for divers.

Main Methods:

  • Case report of a scientific diver with cold urticaria.
  • Review of medical management including antihistamines and corticosteroids.
  • Assessment of diving fitness based on CU symptoms and anaphylaxis risk.

Main Results:

  • The patient remained symptomatic despite antihistamines, even in warm water.
  • She was not cleared for scientific or recreational diving due to anaphylaxis risk.
  • No underlying pathology was identified.

Conclusions:

  • Cold urticaria poses a potentially fatal risk to divers and should be a disqualifying condition.
  • Management may involve antihistamines, corticosteroids, or omalizumab, but anaphylaxis risk persists.
  • Hyperbaric physicians must recognize CU as a cause of post-diving rash and a diving contraindication.
