Choice Medical MD300C Fingertip Pulse Oximeter - Precautions

Precautions for use

• Do not use the pulse oximeter in an MRI or CT environment
• Do not use the pulse oximeter in situations where alarms are required. The device has no alarms.
• Explosion hazard: Do not use the pulse oximeter in an explosive atmosphere.
• The pulse oximeter is intended only as an adjunct in patient assessment. It must be used in conjunction with other methods of assessing clinical signs and symptoms.
• Check the pulse oximeter sensor application site frequently to determine the positioning of the sensor and circulation and skin sensitivity of the patient.
• Do not stretch the adhesive tape while applying the pulse oximeter sensor. This may cause inaccurate readings or skin blisters.
• Before use, carefully read the manual.
• The pulse oximeter has no SpO2 alarms; it is not for continuous monitoring, as indicated by the symbol.
• Prolonged use or the patient’s condition may require changing the sensor site periodically. Change sensor site and check skin integrity, circulatory status, and correct alignment at least every 4 hours.
• Inaccurate measurements may be caused by autoclaving, ethylene oxide sterilizing, or immersing the sensors in liquid may cause inaccurate readings.
• Significant levels of dysfunctional hemoglobins(such as carbonxy-hemoglobin or methemoglobin)
• Intravascular dyes such as indocyanine green or methylene blue
• SpO2 measurements may be adversely affected in the presence of high ambient light. Shield the sensor area (with a surgical towel, or direct sunlight, for example) if necessary.
• Excessive patient movement
• Venous pulsations
• Placement of a sensor on an extremity with a blood pressure cuff, arterial catheter, or intravascular line
• The patient has hypotension, severe vasoconstriction, severe anemia, or hypothermia
• The patient is in cardiac arrest or is in shock
• Fingernail polish or false fingernails may cause inaccurate SpO2 readings.
• Follow local ordinances and recycling instructions regarding disposal or recycling of the device and device components, including batteries.
