ECG setup

Sweep Speed Set the speed of the waveform sweep. Speeds are: 12.5, 25, and 50 mm/s on

a 9” screen. The 12.5 mm/sec speed is suggested for monitoring patients with a slow HR to

show more QRS complexes per sweep. The 50 mm/sec speed is recommended when monitoring patients with a high

HR or when using cascaded ECG. NOTE: The sweep speed is same for ECG, plethysmographic, and invasive

pressure waveforms.

HR Source Select the heart rate source. If ECG signal is too noisy for reliable heart rate

calculation, heart rate can be calculated from pressure (Art) or pulse oximetry (Pleth). The heart rate source appears above the numerical display of the heart rate.

The AUTO selects the first available of ECG, Art, and Pleth.

5 Lead Cable If you use a 5-lead trunk cable with a 3-lead set, select 3elect on, otherwise the

‘Leads Off’ message will be displayed.

Grid Select ON to display ECG waveform with 0.5 mV grid lines. Pacemaker Selects how to display the pacing pulse of a cardiac pacemaker, Show, Hide or

ON R. Hide: The pacing pulse is filtered from the waveform. Show: As above, but the pulse is marked with a constant height marker.

Datex-Ohmeda S/5 Light Monitor

ON R: Pacing pulses are not filtered from the waveform. This improves ECG monitoring with A-V pacemaker patients, as the QRS complexes are counted even if the pacing pulse hits the complex. On the other hand, during asystole the monitor may count pacing pulses as heart rate.

Setting heart rate alarm

Heart rate alarms can be adjusted in the Alarms Setup menu or accessed through the ECG & Resp. menu. See more detailed instructions in the “Alarms” chapter.

Alarm messages are explained in chapter “Maintenance and troubleshooting;

Alarm and information messages.”

Pacemaker patients

The monitor detects and rejects pacemaker pulses, see selection Pacemaker in the ECG Setup menu. Sometimes this may lead to unnecessary asystole alarms. The pacemaker may well change the shape of QRS so much that QRS detection may be affected.

WARNING PATIENT SAFETY: Monitor may count pacemaker pulses as heart

rate during cardiac arrest, some arrhythmias, or with certain types of pacemakers, particularly in ON R mode. Do not rely entirely upon alarms. Keep pacemaker patients under close surveillance.

Respiration

15. RESPIRATION

Respiration measurement uses ECG electrodes to measure the impedance changes caused by breathing.

The measurement is intended for patients three years old and up.

WARNING PACEMAKER PATIENTS: The impedance respiration

measurement may cause rate changes in Minute Ventilation Rate Responsive Pacemakers. Set the pacemaker rate responsive mode off or turn off the impedance respiration measurement on the monitor.

Monitoring respiration

Respiration measurement is activated when a digit or waveform field is selected for it:

• Press the Menu key.

• Select Monitor Setup.

• Select Waveform Fields or Digit Fields.

• Select Resp. to be displayed on an appropriate field.

Sweep Speed Set the speed of the waveform sweep. Speeds are: Fast 6.25 and Slow 0.625

mm/s on a 9” screen.

Resp. Rate Source

Select the respiration rate source of AUTO, CO2 and Imped. The AUTO sets the CO2 first, and if it is not available, impedance respiration is used. Default selection is AUTO.

Measurement Select ON to measure impedance respiration and OFF to set the measurement

off. Default selection is ON.

Detection Limit Adjusts measurement sensitivity. Selections are AUTO, 20%, 40%, 60%, or

100%. The percentage is the ratio to the 1 Ohm reference bar which is 100%.

Limitations of measuring

Movement artifacts

Changing the patient position, moving the head, moving the arms or shaking will result in movement artifacts. Also the heart may cause noticeable movement, and sometimes this may interfere with the respiration measurement.

Respiration

Electrical interference

Electrical devices that emit electromagnetic disturbance will result in artifacts or disable the respiration measurement completely. Such devices are electrosurgery units and infrared heaters, among others.

Intermittent mechanical ventilation

During spontaneous breathing the ventilator may at times support the patient’s ventilation with an extra inspiration. If these ventilator inspirations are substantially larger than the spontaneous breaths, the respiration calculation may mistakenly count only the ventilator produced inspirations and expirations. You can correct this by manually adjusting the detection limits.

1. Press the Menu key.

2. Select ECG & Resp.

3. Select Resp Setup.

4. Select Detection limit.

Measuring principle

ECG electrodes are used to measure impedance change across the thorax. Impedance change is caused by movements and changing air volume in the lungs.

16. PULSE OXIMETRY

Pulse oximetry is used for monitoring oxygen saturation (SpO2), pulse rate, and plethysmographic waveform.

The plethysmographic pulse waveform reflects the changes in blood pulsation at the measuring site. The amplitude of the waveform reflects the strength of perfusion, except when using the Nellcor option, N-LNSAT.

Pulse oximetry is measured with a sensor from finger, toe, ear, or with little children, from palm or feet.

Plethysmograph

The waveform is a good indicator of measurement validity. If the wave is noisy, amplitude is low, or the normal waveform cannot be seen, attach the sensor again.

Dyshemoglobins

The pulse oximeter cannot distinguish between oxyhemoglobin and dyshemoglobins. Thus, the SpO2 values may be erroneously high in smokers or in patients who have burns or carbon monoxide (CO) intoxication.

Adjustments

Setting SpO2 alarms

The alarms can be adjusted in the Alarms Setup menu, accessed through the SpO2 & Temp menu. See more detailed instructions in the chapter “Alarms.”

Alarm messages are explained in the chapter “Maintenance and troubleshooting; Alarm and information messages.”

Measuring principle

Oxygen saturation, SpO2, expressed as a percent, defines the amount of oxygen carried compared to total capacity (also called functional or in vivo oxygen saturation). It is measured by a two wavelength pulse oximeter.

The SpO2 value is measured by light absorption technique. Red and infrared light (660 nm and 910 nm) is emitted from the light source. The amount of transmitted light is detected in the detector half. When the pulsative part of the light signal is examined, the amount of light absorbed by arterial hemoglobins is resulted, and the saturation level can be calculated.

The saturation percentage is displayed numerically, and the pulse beep sound varies according to the saturation level.

Plethysmographic pulse wave

The plethysmographic pulse wave is derived from variations of the intensity of the transmitted light and reflects the blood pulsation at the measuring site.

Pulse rate

Pulse rate is calculated from the plethysmographic pulse wave.

Alternative SpO2 measurement

As an alternative to the Datex-Ohmeda pulse oximetry, the monitor can be equipped with the Nellcor compatible saturation option, N-LNSAT. With this option you can use the sensors listed below.

NOTE: When the monitor has the N-LNSAT option, the monitor is equipped with the Nellcor measurement only and cannot use Datex-Ohmeda Sat Sensors.

Plethysmographic scale

You cannot adjust the scaling when using the N-LNSAT option; it is automatically set by the monitor.

NIBP alarms

NIBP Alarms are set in the Alarm Setup menu, see the “Alarms” chapter. The alarm messages are explained in chapter “Maintenance and troubleshooting.”

Measuring principle

The non-invasive blood pressure (NIBP) measurement uses the oscillometric measuring principle. The cuff is inflated with a pressure slightly higher than the presumed systolic pressure, then slowly deflated at a speed based on the patient’s heart rate, collecting data from the oscillations produced by the pulsating artery. Based on this data, the unit calculates values for systolic, mean and diastolic pressures.

Invasive blood pressure

19. INVASIVE BLOOD PRESSURE

Two invasive blood pressures can be measured with the model F-LMP1.

WARNING PATIENT SAFETY:

All invasive procedures involve patient risks. Use the aseptic technique. Follow catheter manufacturer’s instructions.

WARNING Ensure proper contact of the return electrode of the

electrosurgery unit to your patient to avoid possible burns at sensor sites.

WARNING Make sure that no part of the patient connections touches any

electrically conductive material including earth.

WARNING Use only defibrillator proof transducers and cables.

Monitoring invasive pressures

Preparing pressure line

• Prepare the transducer kit according to transducer manufacturer’s

instructions. Ensure there is no air in the line.

• Connect the kit to the transducer cable and the cable to the red

connector in the monitor.

• Mount the transducer kit at heart level.

• Connect the patient catheter to the pressure line.

• Zero the transducer.

• Open the line to the patient.

transducers

select Zero Px in the NIBP & Inv. Pressure menu.

The messages ‘Zeroing’ and ‘Zeroed’ are displayed accordingly. After

the channel is zeroed, the zeroing time appears in the menu. If the zeroing fails, the previous zero is used.

Invasive blood pressure

• Open the transducer to the patient.

NOTE: ICP can be zeroed via the NIBP & Inv. Pressure menu only.

CAUTION Mechanical shock to pressure transducer may change zero balance

and calibration.

Invasive pressure display

After the line is zeroed and opened to the patient, the pressure wave appears. If two pressures are measured they can be combined with individual scales.

(Select separate or combined waveforms in the Monitor Setup/ Waveform Fields menu, see chapter “Monitor setup”).

Ventilation Mode

Select Spont or Contrl for spontaneous or controlled ventilation. Respiration may cause artifacts in invasive pressure measurement.

HR Source Select the heart rate source. If the ECG signal is affected by too much noise for

a reliable heart rate calculation, heart rate can be calculated from pressure (Art) or Plethysmographic pulse waveform (Pleth). The selected heart rate source is shown above the numerical display of the heart rate.

AUTO selects the first available of: ECG, Art, and Pleth.

Invasive pressure alarms

Invasive pressure alarm is active only after pressure channel has been zeroed. For alarm setup, see the “Alarms” chapter. Alarm messages are explained in the chapter “Maintenance and

troubleshooting.”

Measuring principle

The transducer converts the pressure variations into electrical signals. The electrical signals are amplified and displayed as numeric pressure values and waveforms.

Carbon dioxide

20. CARBON DIOXIDE, CO

CO2 can be measured with mainstream method (N-LCM option) using Mainstream CO2 Sensor and airway adapter.

Respiration rate is the frequency of the peak (end tidal) CO2 value per minute.

Monitoring mainstream CO

Figure 20-1 Connecting mainstream CO2 sensor

1. Connect the special airway adapter between the elbow adapter and Y-piece with the saddles upright.

2. Attach the Mainstream CO2 Sensor to the adapter between the saddles so that the sensor cable fits into the slot on the farther saddle. Ensure the connection between the sensor and the adapter with the Velcro tape supplied with the sensor.

3. Connect the sensor to the connector on the monitor’s side panel.

Place the adapter as close to the patient airway as possible. Make sure that the sensor remains in upright position.

Datex Ohmeda S/5 Light Monitor

To remove the adapter:

• Detach the sensor before removing the adapter from the circuit.

CAUTION Do not apply force to the sensor or sensor cable.

Select the airway adapter according to the patient’s status. Refer to the instructions for use provided in the adapters package.

Using the adult/pediatric mainstream airway adapter (endotracheal diameter ≥

5.5 mm) increases the dead space by 6 ml. With the low dead-space airway adapter (diameter < 5.0 mm), the increase is 0.6 ml.

NOTE: Airway adapter selection recommendations should be used as a guideline. It is important for the clinician to assess each patient when selecting the appropriate airway adapter.

WARNING Do not allow the CO2 sensor to come in contact with the

patient’s skin for a prolonged period of time. Mainstream sensor

is heated to prevent the fogging of the airway windows. WARNING Do not immerse the sensor in liquids or autoclave it. WARNING Do not use damaged sensors or adapters. WARNING Do not clean or sterilize a single use adapter.

CO2 adjustments

Measurement Set on mainstream (MainSt) or turn the measurement OFF. Scale Selects 0 - 6 %, 0 - 10 %, 0 - 15 %, or kPa and 0 - 50 mmHg,

0 - 80 mmHg, 0 - 100 mmHg. Scale 0 - 6% is used in normal situations, 0 - 10% and 0 - 15% scales are used if hypercarbia is expected.

N2O/O2 Comp Selects compensation: OFF, N2O or O2. In the breathing circuit when there is

50% or more of N2O, use N2O compensation; when ther is 60% or more of O2, use O2. In other cases, turn off the compensation.

Unit Selects CO2 unit: %, kPa or mmHg. See “Unit conversions” later in this chapter. Sweep Speed Selects Fast (6.25 mm/sec) or Slow speed (0.62 mm/sec). Slow waveforms

have a sweep speed one tenth of normal, for a full screen sweep (five minutes). Slow waveforms show changes better than fast waveforms.

Resp Rate Source

Change respiration rate source: AUTO, CO2 or impedance respiration.

CO2 Alarm Brings you to the Alarms Setup menu to adjust CO2 alarms. Main Menu Returns you to the Main Menu.

Calibration check

No routine calibration by user is required. Calibration check is recommended to be performed once a year by a qualified technical personnel. See the “Technical Reference Manual” for instructions.

Datex Ohmeda S/5 Light Monitor

Unit conversions

Relationship between gas concentration and its partial pressure: reading in mmHg = (ambient pressure mmHg * gas concentration in %) / 100 reading in kPa = (ambient pressure in mmHg * gas concentration in % ) / 750

Measuring principle

The CO2 measurement is based on the infrared absorption. In the mainstream method the measurement bench is located at the patient’s airway adapter.
