The Patient Data Module is a portable acquisition device. It collects data from a
patient, converts the data to a digital form for processing, and sends the data to a
bedside, transport or surgical monitor for further processing and display.
The data that it collects, converts, and sends includes the patient's vital signs and
physiological waveforms. It also stores patient history including trends and special
events, and setup information such as blood pressure zero points and alarm limit
settings. The patient history is stored so that the collected information is transferred
when a patient is transferred to a different monitor.
The Patient Data Module shares power and communicates with host devices through
the host interface connection called the ePort. The Patient Data Module connects
directly to a transport patient monitor through a docking station. The Patient Data
Module connects to a bedside host patient monitor through the host interface cable
and docking station.
The Patient Data Module contains software and hardware to monitor the following
parameters:
ECG/respiration
Noninvasive blood pressure
Pulse oximetry
