 Martin's small crew, fewer than 10 people, responds to 911 calls across a dusty 3,000 square mile range of rural West Texas. A lot of what we're seeing now with the heat is environmental, some dehydration, some heat exhaustion, things like that. Martin says they also get calls from people with chronic health issues. Some patients don't understand their medications. They don't make me feel good, so I don't want to take them, so I don't take them, and then I end up being a 911 call. The closest hospital is more than an hour away.
