Imagine being trapped beneath the rubble of a collapsed building with no food or water and limited breathing space. As hours turn into days, the body begins to weaken. According to medical and emergency response experts, survival in such circumstances depends on several factors, including a person's age, general health, body reserves, access to breathable air, and the nature of their injuries.
Physician and gastroenterologist Dr. Nashon Okanga explains that the body initially relies on stored energy to sustain vital functions when food is unavailable. As starvation continues, it breaks down fat and eventually muscle tissue to meet energy needs. Dr. Okanga notes that survival varies from one individual to another, with children, older people, and those with underlying medical conditions facing greater risks of deteriorating rapidly.
The absence of water presents a more immediate danger, with severe dehydration becoming life-threatening within days. Dr. Okanga emphasizes that prolonged starvation forces the body to draw on its energy reserves, leading to muscle tissue breakdown, compromised bodily functions, and increased risk of organ damage.
Fred Majiwa of St John Ambulance notes that circumstances surrounding a building collapse significantly affect a trapped person's chances of survival. Victims may be exposed to dust, restricted airflow, physical injuries, and prolonged compression, complicating rescue efforts. Movement can increase energy demands, particularly when a trapped person struggles to free themselves.
Majiwa stresses that rescuers must exercise extreme caution when dealing with victims pinned beneath heavy objects. Removing the weight without proper assessment and medical support can expose victims with crush injuries to further complications. Prolonged compression can damage muscles, release harmful substances into the bloodstream, and trigger disturbances in the body's chemistry.
For people caught in a building collapse, Majiwa advises protecting the nose and mouth from dust and debris while trying to alert rescuers to their location. He recommends conserving energy and avoiding unnecessary movement while waiting for help. If possible, trapped individuals should use available means to signal rescuers without exposing themselves to additional danger.
Ultimately, survival is not just about time; it depends on the conditions endured and the quality and speed of the rescue response. Prompt, carefully coordinated emergency intervention can make a critical difference between life and death. Experts emphasize that every rescue is a race against time.
Key points
- The body's survival without food or water depends on factors such as age, health, and injuries.
- Prolonged starvation and dehydration can lead to muscle tissue breakdown and organ damage.
- Prompt and coordinated emergency response is critical in rescue efforts.
