Extreme heat is the leading weather-related threat in the U.S., with Phoenix experiencing temperatures expected to reach 115 degrees. In Phoenix, heat-related deaths surpass homicides annually, prompting the city to adopt an unconventional method: bags of ice. The Phoenix Fire Department is implementing a new protocol to address heatstroke, as reported by Ben Tracy of Climate Central.
Firefighter Colin Kennedy noted the critical temperature threshold of 105 to 106 degrees, emphasizing the dangers of heat exposure. In a demonstration, firefighters showcased their standard heatstroke protocol, which involves placing individuals experiencing heatstroke into a blue bag filled with ice water to rapidly lower their body temperature before transporting them to the emergency room.
Captain Dave Kirk explained that the practice of cold water immersion has military origins and is becoming increasingly vital as climate change leads to more frequent and severe heat waves. Phoenix now faces 39 additional hot summer days compared to 1970, with Climate Central reporting an increase in dangerous multiday heat streaks across the country.
Traditional methods of treating heatstroke, such as using ice packs and cold IV fluids, are being supplemented by this new approach. The ice bag method can cool patients three to five times faster, which is crucial for preventing brain damage and organ failure.
Each fire station in Phoenix is equipped with eight bags weighing seven pounds each, which are taken on calls. This summer alone, the rapid cooling bags have been utilized over 220 times, and ice is also stockpiled at popular hiking trails to assist overheated hikers.
Dr. Geoff Comp from Valleywise Health Medical Center highlighted the effectiveness of cooling patients before they reach the hospital, stating that reducing the time patients are exposed to high temperatures significantly decreases mortality rates.
This initiative represents a proactive approach to addressing the health risks associated with extreme heat in Phoenix, as reported by Ben Tracy for PBS NewsHour.
