Respiratory Rate Module type 684

The HSE Respiration Rate Module is used to determine respiration frequency (rate) in the range from 3 to 150 breaths per minute. This module is a plug-in module which is used in conjunction with a Bridge Amplifier (DBA) or a Carrier Frequency Bridge Amplifier (CFBA) together with a differential pressure transducer and a pneumotachometer. The input signal is connected either internally through the PLUGSYS bus system or externally direct through the input connector from an external amplifier.

Description

Input selected by switch (indication through LED)
a) internally: signal through 96-pin connector from the PLUGSYS bus system
b) externally: from an external amplifier

Input filter band-pass, bottom and top frequency limit selected separately within the ranges 0.04 / 0.2 / 1 Hz and 5 / 10 / 20 Hz

Trigger operation adjustable over a wide range through 10-turn potentiometer

Range 3 ranges are available, selected by a switch
• 30: 3 to 37,5 breaths/min
• 60: 6 to 75 breaths/min
• 120: 12 to 150 breaths/min

Indication 3½-digit LED display (0 to 1000 breaths/min); additional trigger response check through LED in display field

Outputs • the analogue frequency signal is available at a BNC socket on the front panel (0 to 10V) and through the connector on the PLUGSYS bus system
• the external input signal (10 V) can also be passed to the PLUGSYS bus system

Output filter three positions: 2.5 / 5 / 25 s, are provided for smoothing the recording

Calibrating the respiration rate on the recorder, i.e. setting the rate (shown at the display) in relation to the pen deflection on the recorder. The recording range for respiration rate is set by using the trimmers CAL and SUP. Adjustment is through 10-turn trimmers and the CAL/SUP value is shown by the LED display on the front panel. The chosen CAL values are switched to the display and to the output for feeding into the recorder by setting the CAL switch to “CAL”.

Signal output MUX after pressing the MUX key the response signal is switched to the system bus line AM (analog multimeter) which can be switched to an optional digital Display Module DM or a Digital Voltmeter DVM. The function is self-maintained; the module previously selected is switched off.

Power supply 5 V, 450 mA, through connector from PLUGSYS bus system

Dimensions module for 19 inch rack, width 8E ( 40.5 mm),height 3U (128.7 mm), depth Europe size (220 mm)

Connector DIN 41612, 96-pin VG

Weight 450 g
