Check the patient’s skin condition periodically and change the electrode site as required. 2.Connect the lead cable to the relay cable. 3.Plug in the relay cable to the ECG input connector (green) of the patient monitor. 4.Verify that the ECG waveform is displayed on the monitor. Adjust the waveform size and position. The monitoring lead can be also changed. Reference Refer to “ 6. Parameter Setup ECG” for size / lead setup. 3 5 About the Arrhythmia Analysis Arrhythmia Analysis Flow Learn Waveform QRS Judgement VPC? Pattern Matching VPC! Arrhythmia The arrhythmia detection algorithm learns the normal waveform of the patient and compares the waveform (QRS pattern) and RR interval for each heartbeat to determine the VPC. It compares the parameters such as QRS amplitude, QRS width, QRS polarity, RR interval, and selects abnormal QRS. Then the QRS with suspected VPC is pattern matched to distinguish the noise and VPC. This will finally determine the VPC and generate the arrhythmia alarm. QRS Classification Each heartbeat will be classified to the following patterns according to the QRS judgement. N (Normal)Normal QRS beat V (VPC)Ventricular Extrasystole S (SVPC)Supraventricular Extrasystole P (Pacing Beat)Pacing beat F (Fusion Beat)Fusion beat of pacing and spontaneous beat ? (Undetermined Beat)Learning arrhythmia, or beat not matching the pattern Arrhythmia Type With the above QRS judgement, the following 12 types of arrhythmia alarm can be generated. TypeMeaningDetection Criteria ASYSTOLECardiac Arrest Cardiac arrest is detected for more than preprogrammed time. VFVentricular Fibrillation A random, rapid electrical activity of the heart is detected. VTVentricular Tachycardia 9 or more continuous ventricular beats are detected. (HR: 140bpm / 120bpm or over) SLOW_VT 9 or more continuous ventricular beats are detected. (HR: under 140bpm / 120bpm) TACHYTachycardiaHR is over the upper alarm limit. BRADYBradycardiaHR is below the lower alarm limit. RUNConsecutive VPC Continuous VPC exceeding the preprogrammed value is detected.

3 14 To Measure the NIBP 1.Select the appropriate cuff type for the patient. According to the AHA (American Heart Association) guideline, the appropriate cuff width is 40% of the arm circumference. Select the appropriate cuff from the following selections. Infant Cuff CUF-7105 Width 8.5cm Pediatric Cuff CUF-7104 Width 10.5cm Adult Cuff (small) CUF-7103 Width 11cm Adult Cuff (medium) CUF-7102A Width 14.5cm Adult Cuff (large) CUF-7101 Width 17cm 2.Connect the cuff to the air hose, and then connect the air hose to the cuff connection connector on the monitor. 3.Apply cuff to the patient. Position the ARTERY mark over the artery on the patient’s arm and wrap the cuff around. A finger should just fit in between the cuff and arm. 3 15 Check Point Align the cuff height and heart position to eliminate an error caused by the blood weight. It is most appropriate to measure with the patient lying down and arms naturally extended. 4.Start the measurement. Pressing the NIBP START/STOP key will start inflating the cuff pressure and starts the measurement. Upon completion, the measured value will be displayed inside the NIBP parameter key. WARNING Before the measurement, make sure the patient type ( Adult / Child / Neonate ) is properly selected. Otherwise, correct measurement can not be performed, and congestion or other injury may result. CAUTION ? Pay attention when measuring the NIBP of patient with bleeding disorders or hypercoagulation. The cuff inflation may cause petechia or circulatory failure by the blood clot. ? If the air hose is twisted, or weighed down, the cuff air can not be exhausted. Properly arrange the cuff and air hose. 3 To Measure the NIBP 3 16 Procedure for Periodic Measurement 1.Press the NIBP parameter key on the home display. The NIBP setup menu will be displayed. 2.Press the Auto Mode key on the NIBP setup menu. The interval time setup menu will be displayed. 3.Select an interval time. Press the key for the desired interval. Check that the key LED is lighted for the selected interval. The measurement will automatically start at the selected interval. The measurement time will be integral multiple of the selected interval time starting from 0 minute. Ex.) If the present time is 13:14, the measurement time will be as follows for each interval time. 2 min.: 13:16, 13:18, 13:20, ... 2.5 min.: 13:15, 13:17:30, 13:20, ... 3 min.: 13:15, 13:18, 13:21, ... 5 min.: 13:15, 13:20, 13:25, ... 3 17 To Measure the BP 1.Connect the 2ch BP conversion cable to the monitor and interface cable. 2 channels of BP can be measured on this monitor. Connect the monitor and the interface cable via 2ch BP conversion cable. 2.Assemble the BP measurement device. The following procedure explains the case when BP transducer (COBE CDX series, No.041-575- 504) is used. If using other transducers, refer to the operation manual for the corresponded transducer. (1)Check if the package of the transducer is not damaged before opening. Verify that each connector is securely connected. (2)Align the bracket to patient’s heart position (about 1/2 of the chest depth). 2ch BP Conversion Cable Interface Cable 3 To Measure the BP 3 18 (3)Inject the heparin 1000 units to saline bag, mix thoroughly and puncture the infusion line through the same hole. Set the saline bag to pressure bag, and hang from the infusion device. Fill saline to about 1/3 of the drip. (4)After loosening the zero-port plug, push the flash button to perform priming to remove air bubbles. (5)Verify that all air bubbles are removed, and tighten the zero-port plug. Turn on the zero-port plug side of the open-air three-way cock. (6)Inflate the pressure bag to 300mmHg. (7)Wait about 5 minutes after setting the blood pressure device. Next procedure is to perform the zero balance. 3 19 2.Perform zero balance. (1)Loosen the zero-port plug on open-air three-way cock one-half turn. (2)Press the BP parameter key on the home display. The display will proceed to BP setup menu. (3)Press the BP Zero key on the BP setup menu. Zero balance will start. (4)Turn off the zero-port plug side of the open-air three-way cock. (5)Connect the catheter to the end of monitoring line. The preparation for measurement is complete. 3 To Measure the BP 3 20 3.Start the BP monitoring. Start the BP measurement. Press the Home key. Verify that the BP waveform and each measurement value is displayed on the home display. CAUTION If the SYS value is abnormally high, or DIA is abnormally low, a resonance may be the cause. If the resonance can not be eliminated by adjusting the blood pressure filter, check the BP line and use a thick, short, and hard catheter. CAUTION The zero balance procedure is required for the following case. ? When starting a measurement. ? When the heart position has changed due to body movement. ? When the transducer position has changed. ? When measuring for a long period of time and there is a possibility of measurement error due to change in ambient temperature, etc. ? When a connector is connected / disconnected, or a transducer is replaced. 3 21 To Measure the CO 2 Concentration (DS-7141) The DS-7141 incorporates CO 2 measuring unit. Patient Application and Display 1.For intubated patient (1)Attach the airway adapter to respiration circuit. (2)Remove the protective cap on the airway adapter, and connect to the sampling tube. (3)Connect the other end of the sampling tube to the patient monitor. Verify that all the tubes are properly connected. WARNING ? Use the specified sampling tube and nasal prong manufactured by Oridion. ? Always consider the circumference of the intubation tube when using the airway adapter. If inappropriate airway adapter is used for a patient with low ventilation, CO 2 may mix in to the inspired air resulting in incorrect measurement, or apnea detection may become difficult. 2.For patient using the nasal prong (1)Attach the nasal prong to the patient. (2)Connect the nasal prong to the patient monitor. Verify that it is properly connected. 3…
