Patients, especially the ones that require extensive care requires frequent monitoring in order to keep up with their health conditions. Therefore, the doctors or the caregivers are forced to conduct round-the-clock monitoring in order to enhance the accuracy and also prevent an emergency from happening without the knowledge. However, since the doctors or the caregivers have no way that they can predict the uncertainty; the only method to keep close to such a situation is by monitoring twenty-four hours a week. However, such a task tends to be very tedious and certainly, it is not cost-effective. The caregivers have to attend to the patients in order to manage the pains, bathing and other necessary daily activities that need to be attended to the patients on daily basis. It is not possible for a caregiver to be available to a patient twenty-four hours a day. Sometimes, doctors and caregivers have to leave the patients sometimes, unless there is an alternative exchange of duties. In case there are no multiple caregivers to alternate the duty, then, there is a high possibility that in their absentia an emergency is likely to happen. That is why the doctors and the caregivers recommend the use of the 911 help now systems.
It is worthy to note that, an individual also requires rest. The doctors and caregivers also have a life to attend to as well as the family members. Nowadays, the 911 help now systems have been advanced and made efficiently. Today's models are advanced and light as compared to earlier models which used to be bulky such that it could not be worn even during when a patient is bathing. For example, most of the devices were not waterproof and the devices would not function well or make an alert in case a patient fall in the bathroom. Such cases ended up being fatal if the patient's situation is not noted and attended to as fast as possible.
However, the current design is sophisticated and can be used to alert any occurrence of a situation in any condition. The designs are durable and light-weight such that they can be worn at any time. The seniors who require the devices only need to wear the devices and make an alert. The operation of the device is not complicated since it requires pressing of the button when the need arises. That has helped save a lot of patients from succumbing form health situations such as heart-attacks or feeling dizziness when sick in case the patients are alone in their houses. Therefore, they are very vital for saving lives and at the same time making the work of the doctor and caregivers much easier.
