Page 40 Note Place the electrodes on the patient before the electrode cable is plugged into the monitor. Special consideration should be given to electrode placement when an electrosurgical unit is to be used. The active electrodes should be equidistant from the proposed cutting line, but situated as far away as possible.
Page 41 Patients with burns may need special needle electrodes. Star55 has 3 / 5 lead ECG options for monitoring ECG. L&T offers either of these cables: • 3 lead ECG cable (I, II, III) • 5 lead ECG cable (I, II, III, aVR, aVL, aVF, V) Star 55...
Page 42: Respiration
18-20 breaths per minute. There are several ways to measure respiration. In Star 55, respiration can be measured either through Capnography or ECG. Priority is given to Capnography.
Page 43: Temperature
TEMPERATURE Temperature is one of the important parameters of multiparameter monitor. L&T offers dual temperature monitoring facility in Star 55 series. It is a useful diagnostic tool when differential temperatures needs to be monitored. e.g.: Body temperature of premature baby and temperature of the incubator.
Page 44: Pulse Oximetry
With each heart beat, a pulse of oxygenated arterial blood flows to the sensor site. This oxygenated hemoglobin differs from deoxygenated hemoglobin in the amount of red and infrared light that it absorbs. The Star 55 measures absorption of both red and infrared light and uses those measurements to determine the percentage of functional hemoglobin that is saturated with oxygen.
Page 45 Incorrect application or use of a sensor may cause tissue damage or improper operation of the Star 55. Carefully read the “WARNING” section of this manual and the directions for use provided with the sensor.
Page 46 Although the Star 55 is designed to minimize any effects of electrosurgical interference, if such interference gives a problem, evaluate the following solutions: Move the cables of the Star 55 and the cautery unit as far as possible. Plug the Star 55 and cautery unit into different mains socket.
Page 47 If NIBP, SpO and ECG all three are connected to patient; then heart rate (HR) is derived from ECG. Do not measure NIBP continuously, as it might result in prolonged impairment of the blood circulation of the patient. Star 55 2.11...
Page 48 Caution Extreme caution must be taken when NIBP is set to STAT mode for all types of patients. Reports have been made of nerve injury occurring during use of automatically cycled blood pressure measurements. Caution For NIBP measurements : The cuff selected must fit the upper limb properly and must overlap to encircle the limb on which it is applied.

Usually this is where the catheter tip is placed. (For eg., in centrally located catheters, the tip is generally considered to be in the mid-chest position. The transducer level is then set to corresponding to the patient's mid-chest level). Star 55 2.13...

Page 52: Capnography (Optional)
CAPNOGRAPHY Theory of operation The principle of Capnography is based on the absorption of infrared radiation by CO . The technique is known as non-dispersive infrared absorption technique. The spectral region is particularly appropriate for measuring carbon dioxide because it has a strong absorption band in the near Infrared wavelength. CO selectively absorbs specific wavelengths of Infrared light.
Page 53 CO is transported into venous circulation. During contraction of heart, venous blood is pumped through pulmonary circulation to the lungs for gas exchange. Lungs are made up of millions of alveoli, which permits easy gas diffusion Star 55 2.17...
Page 54 from pulmonary blood to alveolar gas space. CO diffuses into this space because continuous breathing keeps CO concentration in alveoli lower than that in pulmonary circulation. During exhalation, gas leaving lungs mixes thoroughly, so Capnograph measures average concentration of CO from all the alveoli.
Page 55 The module prevents the triggering of an auto zero in the following situations: In case of purging until the end of this state. 20 seconds to 3 minutes from the last detected breath. While wait up to 5 minutes for host auto zero enable command. Star 55 2.19...
Page 56 Leak Tightness The leak rate of the module flow system is less than 40 mBr per minute when a 30% vacuum is invoked on the flow system. FilterLine Recognition Safeguard (FRS) The "FRS" enables the module to detect the presence of the FilterLine at startup and in normal operation.
Page 57 Prepare the patient (Refer Figure 2.18 and Figure 2.19) for CO measurement. Use recommended accessories. Screw up one end of the ‘T’ Connector to the unit through Filter Line. Use proper types for adults and neonatal accessories. Star 55 2.21...

Assuring the patient that the procedure will not hurt and setting his mind at ease will help relieve natural anxieties. Ensure the room temperature is warm enough for the patient. B. VOLUNTARY MOVEMENT Figure 8.2 Star 55...
Page 140 IDENTIFICATION : Gross body movement will cause base line deviation. The signal will be present but, there will be baseline wanders. Myoelectricity may be present as well (Refer Figure 8.2). CORRECTIVE ACTION : The patient should be comfortable and relaxed. Again, reassuring the patient that the monitoring will not hurt him, will restore confidence.
Page 141 Electrodes should be placed on fleshy areas which will help to place electrodes properly. Check that the patient cables are not pulling the electrodes and the electrode is attached properly to the body of the patient. Figure 8.5 Star 55 8.11...
Page 142 IDENTIFICATION : This signal usually degenerates with time. Characteristics such as low amplitude, diphasic QRS complexes, 60/50 Hz frequency interference and base line wander will usually be present (Refer Figure 8.5). CORRECTIVE ACTION : Check the electrode to make sure that the electrolyte is moist and is in sufficient quantity and is in proper contact with the electrode and skin.
Page 143 CORRECTIVE ACTION : Bad grounding may also create a shock hazard. If grounding is doubtful, request for an electrical maintenance check. TV sets, electrical cords and fluorescent bed lamps near the bed may also cause 60/50 Hz frequency interference. Star 55 8.13...
Page 144 D. STATIC ELECTRICITY Figure 8.9 IDENTIFICATION : Static electricity may throw the trace off the screen abruptly. The trace will gradually recentre itself within few seconds ( Refer Figure 8.9). CORRECTIVE ACTION : Synthetic fabrics in bed sheets and clothing may generate static electricity. This can disturb the trace abruptly without patient movement, especially when cables without proper shieldings are used.

Page 148 Endotracheal Tube Kinked: Figure 8.16 Waveform Evaluation: Any obstruction will cause an abrupt change in the ascending limb resulting in either a diminished plateau or no plateau. EtCO and slope will depend on the degree of obstruction ( Refer Figure 8.16). Inadequate Seal Around Endotracheal Tube: A Capnogram in which the downward slope of the plateau blends in with the descending limb (Refer Figure 8.17).
