25 EK Pro Simultaneous multi-lead analysis is performed on leads I, II, III, and the V lead (with 5-lead set). This decreases false alarms caused by artifact and increases the accuracy of arrhythmia calls. ECG The following are examples of each arrhythmia the system calls. They are related to our most current level of software. Please consult your Operators Manual for the arrhythmia criteria relating to the level of software currently in the monitor. NOTE: Artifact may still occur due to patient movement, dry electrodes or inadequate skin prep. Artifact Message Alarm is displayed when artifact occurs on the ECG. Full arrhythmia processing is suspended. Lethal arrhythmia is still active, but its accuracy may be hindered by the artifact. Arrhythmia Suspend message will be displayed and a system warning alarm will sound if the artifact lasts for 20 of the last 30 seconds of ECG. At this point it is essential to troubleshoot the source of artifact as no arrhythmia processing is possible at this time. ACC VENT Adult: Accelerated ventricular occurs when six or more ventricular beats are detected with an average heart rate for the ventricular beat between 50 and 100 beats-per-minute. 0 2 Years: Between 60 and 160 beats-per-minute 3 10 Years: Between 60 and 140 beats-per-minute Years: Between 60 and 130 beats-per-minute HR 0 ASYSTOLE Ventricular Asystole occurs whenever the displayed heart rate drops to zero. ATRIAL FIBRILLATION Characterized by random, chaotic, low-amplituded deflections of the supraventricular component of the ECG waveform, resulting in irregular timing of the QRS complexes and an absence of uniform P-waves preceding the QRS complex. 19

26 EGG BIGEMINY Bigeminy occurs when three or more bigeminal cycles (a ventricular beat followed by a non-ventricular beat) are detected. HR 44 BRADYCARDIA Bradycardia is the average of the most recent eight R-to-R intervals at a heart rate less than the set low heart rate limit. NOTE: Changing the low HR Limit will change the Brady Limit. HR 71 COUPLET Coupling occurs when two ventricular beats are detected and have non-ventricular beats before and after the couplet. The coupling interval between the PVCs must be less than 600 milliseconds. 20

27 ECG HR 87 IRREGULAR IRREGULAR This occurs when six consecutive normal R-to-R intervals vary by 100 milliseconds or more. PAUSE Pause occurs when a default time setting interval is exceeded without a QRS complex being detected. The default can range from 1 to 5 seconds at 1/2 second increments. The beat pause selection is adjusted in the ECG: MORE ECG menu. PVC Isolated premature ventricular complexes occur when a premature ventricular beat is detected and has non-ventricular beats before and after. R on T This occurs when a ventricular complex is detected within the repolarization period of a nonventricular beat. 21

28 ECG HR 148 TACHYCARDIA Tachycardia is four R-to-R intervals at a heart rate greater than the set high heart rate limit. NOTE: If a high heart rate limit is changed, the Tachy limit changes. TRIGEMINY Trigeminy occurs when three or more trigeminal cycles (a ventricular beat followed by two non-ventricular beats) are detected. HR 27 V BRADY Adult: Ventricular Bradycardia occurs when a run of three or more ventricular beats is detected with an average heart rate that is less than or equal to 50 beats-per-minute. 0 2 Years: Less than or equal to 60 and beats-per-minute 3 10 Years: Less than or equal to 60 and beats-per-minute Years: Less than or equal to 60 and beats-per-minute 22

29 ECG VFib/VTac Ventricular fibrillation occurs when the ECG waveform indicates a chaotic ventricular rhythm. V TACH Adult: Ventricular Tachycardia occurs when a run of six or more ventricular beats is detected with an average heart rate greater than or equal to 100 beats-per-minute. 0 2 Years: Greater than or equal to 160 beats-per-minute 3 10 Years: Greater than or equal to 140 beats-per-minute Years: Greater than or equal to 130 beats-per-minute VT > 2 Adult: Ventricular Tachycardia > 2 occurs when a run of ventricular beats is detected with a duration of less than six beats but longer than two beats and with an average heart rate that is greater than or equal to 100 beats-per-minute. 0 2 Years: Greater than or equal to 160 beats-per-minute 3 10 Years: Greater than or equal to 140 beats-per-minute Years: Greater than or equal to 130 beats-per-minute 23

30 ECG Pace Detection Indicators QRS Indicator Heart Rate Heart Rate Alarm Limits PVC Count (Full Arrhythmia Only) ST Measurement Point ST Analysis Data ECG Parameter Box Display Leads changes the top displayed (primary) ECG lead. When monitoring in the single lead analysis mode, it is the only lead used for arrhythmia processing. ECG Size changes the size of all ECG waveforms displayed and graphed. Detect Pace turns pacemaker detection On and Off, and accesses Pace Help. 24 Pace 1 and Pace 2 modes use different algorithms for pacemaker artifact rejection. The Pace 2 mode is more conservative in recognizing paced QRS morphologies and is recommended for use whenever possible. (See Pacemaker Troubleshooting QRG). ECG Limits displays a new menu and information window to adjust heart rate and PVC alarm limits. View All ECG displays six leads of ECG.

31 ECG Clear V 2 through V 6 Fail clears the V 2 V 6 Fail message displayed on the screen when only using the 5-leadwire set of a 10-leadwire cable. Arrhythmia Levels turns arrhythmia processing On and Off. Full and Lethal are available with the Cardiac Software Package. Relearn learns a patient s new QRS pattern. This can be useful to correct arrhythmia calls and heart rate values, and to restore ST measurements. During relearning, an X replaces the heart rate value and the message Learning appears on the display. ST Analysis is performed on multiple leads, simultaneously. It identifies the ST segment of the QRS as beginning at the J-Point and ending predetermined milliseconds following the J-Point. The menu options allow turning ST analysis On and Off, printing ST trends and complexes, storing new references, adjusting ST alarm limits, identifying the V lead, and adjusting the ST point. NOTE: Storing new references is for visual reference only and does not affect the ST processing. ECG Filter selects levels of filtering for the ECG waveform data on the display and graph. Filtering affects the ECG waveform only and does not affect ECG analysis and arrhythmia analysis. The moderate filter mode reduces high frequency interface, i.e., ESU. Moderate and maximum ECG filtering are not recommended for pacemaker patients. Maximum Filter alters the displayed ECG morphology. Do not rely on ECG morphology for diagnostic purposes when this filter is selected. 12 Lead ECG Analysis: Display 12 leads of ECG with special menu options for analyzing and printing. LD Analysis: Choose single-lead or multi-lead processing of ECG and arrhythmia. More ECG: Display a new menu to turn the QRS tone On/Off, adjust volume when on, specify the QRS width type, and adjust the beat pause interval. 25

34 NBP Accuracy of NBP measurement depends on using the proper cuff size. It is essential to note the circumference of the limb and check the cuff for proper size using the range markings printed on the inside of the cuff (DINAMAP/Critikon). Inappropriate cuff selection or improper application will result in erroneous measurements. NBP Go/Stop Systolic Value NBP Parameter Window Diastolic Value NBP Auto Timer Limits and Units Time of Last Measurement and Cuff Size Mean Value 28

35 NBP NBP Go/Stop initiates a single NBP measurement without going into the NBP menu. It can also be used to stop a measurement already in progress. NBP Auto starts/stops the automatic mode selects a time interval. NBP Stat starts five minutes of continuous, sequential NBP measurements. (Not available in the Neonatal ICU mode). Review NBP reviews previous NBP measurements stored in vital signs. NBP Limits displays an information window and a new menu to adjust systolic, diastolic, and mean limits. Cuff Size is used to select the type of cuff being used, (adult, pediatric, neonatal), and adjusts the initial inflation pressure. Clear NBP Reading removes the current value from the NBP parameter window. Cleared value will not be stored in vital signs. Initial Inflation Pressure determines the specific target inflation pressure for the first NBP measurement. 29

36 Respiration Respiration Parameter Window Limits and Units Lead Monitored Breath Indicator Respiration Rate Respiration is detected by measuring thoracic impedance. When respiration are monitored, a small AC signal is applied through ECG Lead I or Lead II. This signal appears between the right arm and left arm electrodes, or right arm and left leg electrodes, depending on the selected ECG lead. The lead selected is dependant on whether a patient is a chest breather or an abdominal breather. 30

37 Lead changes the lead from which the respiration rate is derived. (Lead I or Lead II). Relearn Respiration initiates a monitor relearn of the patient s respiration system. Sensitivity increases or decreases the sensitivity setting. The lower the percentage, the greater the detection sensitivity. Respiration Limits displays a new menu and information window to adjust respiration rate and apnea alarm limits. Respiration Auto Size automatically sizes the respiration waveform to fit in a predetermined area on the screen. NOTE: Adjusting the displayed size does not change the sensitivity. Manual Size increases or decreases the size of the respiration waveform. Cardiac Artifact Alarm turns the artifact alarm on and off. The Cardiac Artifact Alarm alerts the clinician to the fact that the respiration rate is within 5% of the heart rate over 30 consecutive breaths. Speed: Change the sweep speed for the displayed respiration waveform.

38 SPO 2 Patient Preparation for SPO 2 Monitoring Choose the probe that is best suited to your patient needs: ear, finger, disposable, reusable, etc. Clean the surface of the probe before and after each patient use. Following the instructions provided with the probe, correctly position and attach the probe to your patient. When a Masimo sensor is repositioned at any time, disconnect the cable from the sensor before repositioning. Reconnect sensor to cable after proper patient preparation and placement. NOTE: Good clinical practice includes proper probe placement and maintenance of probe position on the finger to prevent false SPO 2 readings from ambient light interference. SPO 2 monitoring is a non-invasive technique used to measure the amount of oxygenated hemoglobin and pulse rate. This is done by measuring the pulse absorption of selected waveforms of light. The light generated in the probe passes through the tissue and is converted into an electrical signal by the photodetector in the probe. The monitor processes the electrical signal and displays a waveform and digital values for SPO 2 and pulse rate. The Dash 3000 and Dash 4000 (V5) monitors incorporate two different technology options for interpreting SPO 2 values: Nellcor Masimo Set NOTE: The type of SPO2 technology available is based on equipment purchased. 32

39 SPO 2 SPO 2 Parameter Window Signal Strength Indicators Limits and Units Pulse Rate Value SPO 2 Value In order for accurate SPO2 readings to be obtained by the monitor, it is important to correctly position the probe and verify the quality of the signal. There are three indications from the monitor that verify the quality of the data being displayed: Signal Strength Indicators Three asterisks = good signal strength Two asterisks = adequate signal strength One asterisk = poor signal strength The quality of the SPO 2 waveform: Noise or artifact may be due to poor probe placement or patient movement. Frequent or erratic changes in the value or waveform may indicate a poor signal. NOTE: When using Masimo technology, the waveform cannot be utilized as a quality indicator due to the fact that motion artifact is filtered. The stability of the SPO 2 value: Compare the heart rate in the SPO 2 parameter window with the heart rate in the ECG parameter window to confirm accuracy. NOTE: It is critical to observe all three indicators at the same time. Example of a Good SPO 2 Waveform 33

40 SPO 2 Both SPO 2 technologies include the following menu options: Size adjusts the size of the displayed SPO 2 waveform. The default size is 1x. Rate turns the displayed rate value on and off. Rate Volume turns on a tone that sounds each time a pulse is detected. This is a variable pitch tone which changes as the patient s saturation level changes. The volume of this tone can be adjusted. SPO 2 Limits displays a new menu and information window to adjust SPO 2 percent and rate (beats per minute) alarm limits. Persistent SPO 2 allows the SPO 2 parameter box to remain on the display after the SPO 2 cable has been disconnected. The parameter box displays PROBE OFF PATIENT when the cable is disconnected and an alarm sounds at both the monitor and the central station. This option may be turned on or off in the SPO 2 menu if enabled in defaults. 34

41 SPO 2 SPO 2 Masimo SET allows the sensitivity and averaging times to be adjusted. Sensitivity options include: - Normal for routine patient monitoring purposes. - Maximum for improved low perfusion performance and for faster tracking of SPO 2 changes. SPO 2 Masimo Parameter Window Averaging menu options determine how many seconds the collected SPO 2 information is averaged. Options for averaging times are 2, 4, 8, 10, 12, 14 or 16 seconds.

42 Invasive Pressures Systolic Value Diastolic Value Zero All ART Parameter Window Limits and Units Pulse Rate Value Mean Value Mean Value CVP Parameter Window Limits and Units Zero All is selected to zero multiple pressure transducers at one time: Level all transducers to the phlebostatic axis. Turn the venting stopcocks open to air, closed to patient. Press the ZERO ALL on the Dash series monitor. Verify that zero reference has been established. (Watch the parameter box for message) Close the venting stopcocks to air, open to patient. Each invasive pressure connector is labeled BP. For convenience, the monitor has a specific pressure name assigned to each BP connector. 36 These names can be changed during setup, so any pressure line can be plugged into any BP connector. Having the connectors named properly is important for proper waveform processing, since different algorithms are used for processing different pressure sites. A labeled pressure waveform is displayed when the patient s IBP cable is connected to the monitor. After a zero reference procedure is done, numerics are displayed in the pressure parameter window on the right side of the screen. The current systolic, diastolic, and mean values are displayed. Some pressures only display a mean value (CVP, ICP, etc.)

43 Invasive Pressures CVP Menu Scales changes the displayed scale size for this pressure. Cursor displays a movable cursor over the waveform. Clear Cursor removes the cursor from the waveform. Limits displays a new menu and information window to adjust alarm limits. Change Name displays a pop-up menu listing site name choices for this pressure connector. Zero sets the zero reference for this transducer only. IABP turns the intra aortic balloon pump feature on and off. Smart BP recognizes zeroing, fast flushing, and drawing blood and eliminates needless alarms associated with these procedures. Disconnect Alarm is a feature found in the ART and FEM pressure menus. If the mean pressure falls below 25 mmhg and the disconnect alarm is on, a warning alarm sounds and the message DISCONNECTED is displayed in the parameter window. Check the patient immediately in the event the catheter has been dislodged. Pulse Rate is found in the ART, FEM, and UAC pressure sites and displays a rate value in the parameter window. BP Filter sets the filter at 12 Hz or 40 Hz. 12 Hz is recommended for general monitoring. Calibrate Transducer adjusts transducer offset. Speed changes the sweep speed for this display. 37

44 Invasive Pressures ART Parameter Window with IABP IABP (Cardiopulmonary Software Package) Triggering GE Medical Systems Information Technologies recommends that the signal source used to trigger an intra aortic balloon pump should be the balloon pump itself. This ensures that the trigger signal is compatible with all modes of IABP. An extra set of ECG electrodes or an additional connection from the arterial line can be connected to the monitor s display for consolidated waveform viewing. The monitor measures arterial (femoral) pressure and displays both the pressure waveform and numeric pressure values. The IABP feature compensates for the irregularities in the pressure waveform caused by the IABP. Starting the IABP Program Select the IABP option from the pressure menu. When ON, the parameter label begins with an I (IART1). 38

45 PA Insert / Wedge PA Parameter Window with Inflate Balloon Message The PA Insertion/Wedge Display was designed to provide the clinician maximum visualization during central line insertion. PA Insertion: To adjust the display when the PA catheter is being inserted, select PA INSERT/WEDGE from the PA parameter box. This removes all BP waveforms from the display, except the PA, to optimize PA visualization. Numerics for all other waveforms are still displayed on the right side of the screen. PA Wedge: To perform a PA Wedge measurement, select the PA parameter box, select PA INSERT / WEDGE. 39 Auto Wedge: Click on the MODE option to change from Manual to Auto. This mode will allow performing a measurement without having to touch the monitor once the program is started. (Manual Mode requires additional steps at the monitor to complete the measurement). Once Auto Mode is active, a message appears in the PA parameter window: INFLATE BALLOON. Print Insertion: When PA Insert/Wedge is selected, choose GRAPH BP INVASIVE to print insertion.

46 PA Insert / Wedge Review Wedge Information Window As the program senses the catheter wedging, the prompt changes to WEDGE PROCESSING. Deflate the balloon once wedging is adequate (3 to 4 respiratory cycles), but no longer than 20 seconds. The prompt will change to WEDGE COMPLETE. A PA Wedge Review information window will automatically appear. It contains 20 seconds of compressed waveform data. Move Wedge Cursor repositions the cursor to change the wedge value. Press the Trim Knob control to confirm and store the new PA Wedge value. Print Wedge: Press GRAPH GO/ STOP to print the waveforms in the PA Wedge Review Window. Once a PA Wedge pressure is confirmed, it will be displayed along with the time of the measurement in the PA parameter box. From the PA menu, the clinician may continue on to the Cardiac Output program by selecting CARDIAC OUTPUT from the menu options. This will also store the PA Wedge pressure value into the Cardiac Calculations and Vital Signs. PA Parameter Window with PAW 40

47 Cardiac Output Cardiac Output Complete The Cardiac Output program measures cardiac output by use of a thermodilution catheter. A numeric value and a real-time cardiac output washout curve are displayed on the monitor. The monitor allows performing multiple measurements and delete those not wanted.
