Inoperative Conditions This chapter gives you additional information about telemetry inoperative conditions (SYNOPSIS. A complete summary of In Ops and alarms can be found in Chapter 3 of the User's Guide. Monitoring During Inoperative conditions {IN OPS) exist when the signal Inoperative cannot be properly processed. IN OPS automatically i. additional s. Ever Condition reset when the condition clears. Every IN OP alarm is nations accompanied by a specific message.
5-2 Note $ Inoperative Conditions When fallback occurs, ECG-CH 2 occupies the sector. An IN OP message, for example LEADS OFF II, appears above ECG-Chi's waveform and the prompt Leads swapped due to lead off appears in the ECG Task Windows. When the condition clears, the IN OP message is removed and ECG-CH 1 returns to the sector. To prevent lead selection which would terminate the fallback mode, the soft key enabling the change of lead or label {or swap) is removed.
Fallback Mode with Arrhythmia Extended Monitoring Mode Note 9 Arrhythmia fallback is a feature of arrhythmia monitoring and occurs even if your telemetry system is not configured for fallback. Arrhythmia fallback occurs if your patient is arrhythmia monitored, ECG-CH 1 is IN OP, and ECG-CH 2 is operative. After a 10 second delay, ECG-CH 2 switches to the sector and arrhythmia analysis and alarms continue to be generated.
with ECG-CH 1 as Lead II and ECG-CH 2 as off, if the left leg (LL) electrode fall off, ECG-CH 2, Lead MCL, turns on, occupies the sector, and becomes the tachycardia lead. When the IN OP of ECG-CH 1 is corrected, monitoring continues as before. Extended Monitoring with the 4-wire Lead Set {(M1400A /B transmitter) Since the 4-wire lead set reconstructs four of its possible 6 leads, ITI, aVR, aVL, aVF, it may be able to continue monitoring if ECG-CH 1 and B are both IN OP.
Configuration Configuration How your telemetry system performs depends in large Choices part on the configuration choices made during system installation. The following tables summarize the factory-set defaults and the alternative configuration choices that relate to clinical practice. Configuration is performed at the receiver mainframe, except for the Dravidian transmitters, which are configured at the wave viewer, and all settings except frequency pertain to all receivers in the mainframe.

Analog Output Option Warning 9 Caution $ The Analog Output Option J01 (Patient Premonitory Interface) gives the HP Dravidian Telemetry System the capability of providing ECG outputs to bedside monitors, Holder monitors, and other recording devices. The Patient Premonitory Interface (Analog Output) Option is intended for display and recording purposes only.
Analog Output Bedside Monitor Cables Note g B-2 Analog Output Option SRE TE To connect the telemetry transmitter to the bedside monitor via the optional Patient Premonitory Interface {Analog Output), you will need an analog output bedside monitor cable. The end of the cable that connects to the bedside monitor will have either a small 12-pin connector or a larger 8-pin connector (See the illustration below). The other end of the cable has a phone plug connector, and it plugs into the wall plate.
There are four different analog output bedside monitor cables. Which cable you use will depend upon whether the input connector on your bedside monitor is 8-pin or 12-pin and whether your transmitter lead set is 3-wire, 4-wire, or 5-wire. The proper cable selection is summarized in the following table. The cables can be distinguished from the 5-wire cable by the attached label (see the table on page B-5). The lead set type also determines which are the valid leads to be selected at the bedside.
Lead Placement and Selection Note $ Caution $ B-4 Analog Output Option To ensure valid waveform with the correct lead label, you must remember to use the following: » standard lead placement (shown on the telemetry transmitter case and in further detail in the section “Electrode Placement” in Chapter 2) w valid lead selection (performed at the bedside monitor) The following table summarizes recommended lead placement and selection.
Using Non-standard Lead Placement With the and 5-wire lead set, you can use non-standard lead placement, but you must still use a valid lead selection at the bedside monitor. This will give you the desired waveform, but it will result in a mislabeled lead at the bedside monitor.
Controls for Telemetry Setup To make adjustments to your patient’s ECG, you will need access to either the Patient Window Task Window on the HP Omnivore Component Central Monitor or a bedside monitor. First, go to the HP Omnivore Component Central Monitor, press and select a patient. If telemetry is not turned on, turn it on here. Then press and make adjustments. If soft key labels for telemetry controls appear, as shown below, you make all adjustments at the central monitor.
RR Functionality with paced Wave forms Caution $ In order for paced waveform to be processed correctly by bedside monitors using the analog outputs, the pace pulses must be artificially reconstructed and inserted into the analog output signals. The synthesized pace pulse is very narrow and may not be visible at the bedside display, depending on the type of monitor used.
Inoperative (IN OP) Conditions Note 9 B-8 Analog Output Option With the Patient Premonitory Interface (Analog Output) Option, the following telemetry inoperative (IN OP) conditions will appear as a LEADS OFF message at the bedside monitor. .
