12.4 limitations for Measurement

Measurement Limitations
In operation, the accuracy of oximeter readings can be affected by:
• High-frequency electrical noise, including noise created by the host system, or noise from external
sources, such as electrosurgical apparatus connected to the system.
• Do not use oximeters and oximeter sensors during magnetic resonance imaging (MRI) scanning. Induced
current could potentially cause burns.
• Intravascular dye injections
• Excessive patient movement
• External light radiation
• Improper sensor installation or incorrect contact position of the patient
• Sensor temperature (optimal temperature between 28°C and 42°C)
• Placement of the sensor on an extremity that has a blood pressure cuff, arterial catheter, or intravascular line.
• Significant concentrations of dysfunctional hemoglobin, such as carboxyhemoglobin and methemoglobin.
• SpO too low

• Bad circular injection of the part being measured
• Shock, anemia, low temperature and application of vasomotor may all cause the arterial blood flow to
reduce and hence make the measurement impossible.
• The absorption of oxyhemoglobin (HbO2) and deoxyhemoglobin to the light of special wavelength may
also affect SpO measurement. If there exist other objects (carbon hemoglobin, methemoglobin, methylene
2
blue and indigo carmine) absorbing the light of the same wavelength, they may result in false or low SpO
value.
• It is recommended to use SpO

Warning
• Setting the SpO upper alarm limit to 100% is equivalent to switching off the alarm on upper limit. High

oxygen levels may predispose a premature infant to retrolental fibroplasia. Therefore, the upper alarm limit
for oxygen saturation must be carefully selected in accordance with commonly accepted clinical practices.
• The upper and lower limit of SpO2 alarm will be displayed continuously in the SpO2 parameter area.
SpO 2 alarm setting
• ALM: pick "ON", the system will give alarm prompt and store alarm information when SpO
pick "OFF", the system will not give alarm and instead display a beside "SpO
• ALM REC: pick "ON", the system will command the recorder to output alarm information when SpO

• ALM LEV: used to set up alarm level, selectable from HI, MED and LO. HIGH represents the most serious
case.
