Frequently Asked Questions

What is the average emergency response time?

The national average EMS response time is about 7 minutes in urban areas and 14 minutes in rural areas. However, this only starts when 911 is called. For someone living alone who falls or has a medical emergency, the biggest delay is often the time before anyone knows to call for help.

Why is detection delay so dangerous?

For strokes, every minute without treatment destroys 1.9 million brain cells. For heart attacks, survival drops 7-10% per minute without defibrillation. For falls, lying on the floor for more than 1 hour dramatically increases complications. Detection delay is often the largest component of total response time for people living alone.

How does a daily check-in reduce response time?

Without any alert system, a person living alone who has an emergency may not be found for hours or even days. A daily check-in like ImAlive limits the maximum detection delay to 24 hours. Combined with a medical alert device, this creates a comprehensive safety net.

Should I get a medical alert device?

Medical alert devices are valuable for anyone at high fall risk or with serious medical conditions. They provide instant help at the push of a button. However, they do not help if you cannot press the button (e.g., unconscious). A daily check-in service like ImAlive complements alert devices by providing a passive safety net.
