4 System Operation
Overview
The EarlySense System is designed to display and log respiration rate, heart rate and
movement parameters in an automatic contact-free manner when the patient is lying in
bed. The System is indicated for use in indoor environments. Monitoring of the patient
begins automatically as soon as the patient gets into bed.
The system design allows the user to set high and low threshold parameters that will alert
the user if either heart or respiration rate have crossed predefined thresholds. The system
can alert the user if patient leaves the bed (bed-exit) and allows the healthcare practitioner
to document that s/he changed patients’ position in bed. The health-care practitioner can
insert the event of patient's change of position by documenting the event on the
EarlySense bedside screen. The system then verifies the change in position and logs the
information. The system also provides an option to notify the user if a certain amount of
time (as set by the user) has passed since last position changing (timer expired). The users
can decide to activate or deactivate these notifications
Data is continuously presented on the Bedside Unit main screen. The data obtained
during the monitoring period is recorded by the system in order to enable off-line
presentation and data printing.
The Sensing Unit should be placed under the mattress, underneath the patient’s chest area
and the system should be turned on. After approximately 60-120 sec of the patient lying
in bed in resting position, the system will begin displaying the monitored values on the
bedside Unit Home screen.
By entering the patient’s basic information (MRN, Initials) into the system the data will
be transferred to the Central Display Station (if being used). Heart and respiration rates
and patient movement level will be continuously displayed on screen. Heart and lung
icons will blink and the values will appear in white on the screen as long as
measurements of HR and RR are current.
