Surface Temperature and Burn Severity in Diving Medicine - Diving Medicine

More Info

---

In diving medicine, understanding the relationship between surface temperature, contact duration, and burn severity is crucial for preventing and managing thermal injuries. Burns are classified into three degrees based on the severity of tissue damage, with third-degree burns being the most severe, affecting all layers of the skin and potentially underlying tissues.


Surface Temperature and Contact Duration
1. Surface Temperature: Third-degree burns typically occur at temperatures exceeding 150°F (65°C). However, the exact temperature threshold can vary depending on several factors, including the individual's skin type, the presence of moisture, and the specific area of contact. For instance, a surface temperature of around 200°F (93°C) can cause third-degree burns in less than a second of contact.

2. Contact Duration: The duration of contact plays a significant role in determining burn severity. Generally, the longer the skin is exposed to high temperatures, the more severe the burn. For example:
- 1 second of contact with a surface at 160°F (71°C) can lead to a second-degree burn.

- 3 seconds of contact with a surface at 140°F (60°C) can result in a second-degree burn.

- More than 5 seconds of contact with a surface at 120°F (49°C) can cause a second-degree burn, while contact at 140°F (60°C) for this duration can lead to a third-degree burn.


Factors Influencing Burn Severity
Several factors can influence the severity of burns, including:
- Skin Thickness: Different areas of the body have varying skin thicknesses. Thinner skin areas, such as the face and inner arms, are more susceptible to burns.

- Moisture: Wet skin can burn more quickly than dry skin due to increased heat conduction.

- Individual Variability: Age, health status, and skin condition can affect how skin responds to heat. For example, elderly individuals or those with certain medical conditions may experience burns at lower temperatures or shorter contact durations.


Prevention and Management
In diving medicine, it is essential to educate divers about the risks of thermal injuries, especially when using equipment that can reach high temperatures, such as exhaust pipes or hot surfaces. Here are some preventive measures:
- Protective Gear: Wearing appropriate protective clothing can help shield the skin from high temperatures.

- Awareness: Divers should be aware of their surroundings and the potential for contact with hot surfaces.

- Immediate Action: In the event of a burn, immediate cooling of the affected area with running cool (not cold) water for at least 10-20 minutes is crucial to minimize tissue damage.


Conclusion
Understanding the relationship between surface temperature, contact duration, and burn severity is vital in diving medicine. Third-degree burns can occur at temperatures above 150°F (65°C) with very brief contact, emphasizing the importance of prevention and immediate treatment. For any burn injury, especially those suspected to be severe, it is essential to seek medical attention promptly to assess the extent of the injury and initiate appropriate treatment.
