A patient monitor is a medical device that collects and stores vital signs of the patient, which together with alarm systems process and record the parameters of the patient. They are teams capable of providing operational facilities for medical staff and modern medical practice. Nowadays, these patient monitors collect information from different physiological parameters and also store trends and events of arrhythmias.
A patient monitor must have an interaction with the user, easy and simple to use by medical staff. It groups the set of works that must be performed from the interaction of the key, its effect on the screen and then its execution in the operation of the monitor.
Criteria for Use of Patient Monitors
Patient monitors have ergonomic designs that meet certain characteristic criteria to be taken into account for the development of their functions, and are:
- Ease of connection to patient, adjustment of scales, alarm limits, etc.
- Configure the basic functions, which should be the required time in which it is required, select the information to be displayed including alarms, parameters, quiet times, etc.
- Change parameters easily by monitoring.
- Taking manual noninvasive pressure measurements
- Cables must be easily accessible, connected to the patient so as not to obstruct the visibility of the screen.
- Regulate alarms based on patients’ conditions.
In this sense, the functions of patient monitors are basically used by trained personnel, so it is not necessary to use a user manual, since the references help explain the function or operation not very obvious to users with functions that are not used frequently. In addition, the monitor should be as simple as possible, allowing the on-screen display from various angles to be clear and precise. As well as using the controls for simple and obvious functions.
Alarm Interface as a Standard for Use of Patient Monitor
It is important to take into account the alarm system that regulates and warns the effectiveness in the use of patient monitors, which are reflected as follows:
- Aperture: Alarms should be triggered as soon as the patient is connected to the monitor and monitoring has begun. Alarms should be initiated by default at reasonable values for each parameter.
- Visual indicator: refers to the identification of any pre-set limit, both sound and visual. These indicators must identify the alarm that has been violated and must be activated within 10 seconds of the alarm condition.
- Mute or Disable: This is important because the user can attend to the patient without worrying about changing the level of the alarm. The silence time should be short and should be automatically reactivated at the end of the silence if the alarm condition remains.
- The default volume must be audible. These variables are between 50 and 60 dB in care and emergency rooms with peaks of 65 to 70 dB by conversations and others. It is important that the alarm tones differ from the other sound signals found on the monitor application sites.
Finally, the neglect of patient monitoring is a special kind of alarm that occurs when an error occurs or because it has been turned off due to low battery charge.
