Medical Services
A medical alert works by connecting a user’s wearable button or device to a 24/7 emergency response center, which then assesses the situation and contacts the appropriate help, such as emergency services, family, or caregivers. The system typically uses a help button, which can be activated manually or automatically if a fall is detected. The center uses two-way communication to confirm if help is needed and can dispatch emergency personnel or notify designated contacts.

How a medical alert system works step-by-step
Activation: The user presses the button on their wearable pendant, bracelet, or other device, or the device automatically triggers a call if it detects a fall.
Signal sent: The device sends a signal to a monitoring center staffed by trained professionals 24/7.
Two-way communication: The response center operator uses a two-way speaker to talk to the user and assess the situation.
Dispatching help: The operator dispatches the appropriate help based on the user’s needs, which could be emergency medical services, a family member, or a caregiver.
Follow-up: If the user does not respond, or in a clear emergency, the operator will proceed with dispatching professional help. The operator also typically notifies designated loved ones or caregivers about the incident.

Key Features
Wearable technology: Devices are typically wearable pendants or wristbands, making them always accessible.
Automatic fall detection: Many systems include automatic fall detection, which can trigger an alarm even if the user is unable to press the button themselves.
24/7/365 monitoring: The response centers are always staffed, so there is a trained professional available at any time of day or night.
Monitored vs. unmonitored: Most systems are monitored, meaning they connect to a call center. Unmonitored systems may be pre-programmed to call 911 or a specific contact directly.
