Older folks or those with medical issues are likely to have a Medical Alarm to help them in the event that they need medical attention and are unable to use the phone to call for it. There are two main scenarios where a person can benefit from these types of alarms.
The first situation is if a person is unable to get to the phone for one reason or another. They might be experiencing a heart attack and have just enough energy to push their Medical Alarm, alerting the authorities and getting an ambulance to their home just in time to save them. Or perhaps they are bound to a wheel chair and are unable to navigate quickly in the event of a fire or other disaster in their home.
The other main situation that a person will use a Medical Alarm is when they have fallen. This scenario requires you to choose a particular type of alarm. Some alarms only alert the authorities when a button is pushed. However, the more advanced options will also alert when a sudden fall is taken. This gives the most protection, because if a person is to fall and become unconscious, they will still get the help they need.
