− To Acquire ECG Waveform − Before turning ON the power 1. Check the grounding. 2. Check the recording paper. 3. Turn ON the power. The magazine will be released by pressing the magazine release button. Properly ground using the 3-way AC plug. The grounding is required to prevent AC noise. Open the recorder magazine, and check that there is enough amount of paper installed. Turn ON the power and check for appropriate display. Before Attaching the Electrodes 1.
PAGE 3
Electrode Placement There are 3-electrode, 4-electrode, 5-electrode application depending on the cable type. Using the 4-electrode or 5-electrode application allows simultaneous monitoring of 2 ECG waveforms, and high accuracy of arrhythmia analysis can be attained. Also, the displayed lead type can be changed.
PAGE 4
Connection to the Patient Monitor 1. Connect the lead cable to the electrode. Clip on the lead cable end to the electrode convex part. ? The indication for continuous use of the electrode is about one day. ? Replace the electrode if the skin contact gets loosen due to perspiring, etc. C A U T I O N ? When an electrode is attached at the same location for a long time, some patients may develop a skin irritation. Check the patient’s skin condition periodically and change the electrode site as required. 2.

About the Arrhythmia Analysis Arrhythmia Analysis Flow QRS Judgement VPC? Learn Waveform 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.

Filter Selection ● Filter Mode Setup The waveform frequency characteristic can be selected from Monitor Mode, ESIS Mode, or ST Display Mode according to the monitoring purpose. 1. Monitor Mode Frequency Characteristic Adult / Pediatric：0.5〜40Hz Neonate：1.6〜40Hz This is the standard mode for ECG monitoring. The upper frequency is set to 40Hz to reduce artifact caused by EMG, etc. 2. ESIS Mode Frequency Characteristic Adult / Pediatric：1.6〜15Hz Neonate：1.
PAGE 7
● Procedure for Filter Mode Selection 1. Press the ECG parameter key and display the ECG setup menu. 2. Press the Config. key. 3 3. Select the filter mode from 3 selections. If the ECG waveform is interfered with AC noise, the AC filter cuts off the frequency component (50Hz or 60Hz). The AC filter is always set to ON. Reference Refer to “8. System Configuration Hospital Setup AC Filter” for AC filter setup (50Hz or 60Hz).

− Respiration (Impedance Measurement) − 1. Verify that the ECG waveform is properly acquired. The respiration waveform is detected from lead Ⅱof ECG mentioned in the previous section. Therefore if stable ECG is acquired, the respiration waveform can be acquired at the same time. 2. Verify that the respiration waveform and respiration rate is displayed on the home display. Adjust the waveform size, baseline position and sweep speed. Reference 3− 8 Refer to “6.

− To Measure the SpO2 − 1. Prepare an appropriate probe or sensor for the patient. Sensor Types Probe Type (Reusable type, for adult finger) DS-100A For adult with weight of 40kg and over. This is for temporary use. When continuously using for long period of time, use the following single-use type. 3 To Measure the SpO2 Single Use Type OXISENSORⅢ N-25 (for neonate toe) For neonate with weight of 3kg and over.

2. Connect the sensor to the patient monitor. (1) Connect the SpO2 relay cable (DOC-10) to the SpO2 connector on the patient monitor. (2) Insert the sensor into the SpO2 relay cable connector, and lock with the transparent part. 3. Attach the sensor to the patient. If the nail is rough, dirty, or manicured, accurate measurement will not be C A U T I O N possible. Change the finger or clean the nail before attaching the probe and sensor.

(3) Press the probe lightly so that the finger and the rubber cover are appressed. This is to stabilize the probe, and to avoid ambient light. 【Single-use Type】 (1) Clean the attachment site with alcohol, etc. 3 Light Emitting Element Light Receiving Element (3) Fixate the cable with surgical tape so that the sensor does not come off when a cable is pulled. Attachment to the toe Attachment to the finger 4. Verify that the SpO2 is displayed. Press the HOME key on the lower part of the display.

● Functional and Fractional Saturation The DS-7100 measures functional SpO2 and may therefore produce measurements that differ from devices measuring fractional SpO2. "Functional" SpO2 is the amount of oxygenated hemoglobin expressed as a percentage of the total amount of hemoglobin capable of transporting oxygen. By utilizing the light of two different wavelengths, the DS-7100 can analyze for both oxygenated and deoxygenated hemoglobin, and consequently, can determine the functional SpO2.
PAGE 13
CAUTION 3− 13 3 To Measure the SpO2 ? If irritation such as skin reddening or skin fit appears with the sensor use, change the attachment site or stop using the sensor. ? When fixating the sensor with a tape, do not wind the tape too strong. At the same time, check the blood flow constantly so that congestion is not generated at the peripheral. ? Even a short duration of attachment may inhibit the blood flow and generate compression necrosis and burn injury.
