VM15 User Manual Masimo SpO2
Monitoring (Option)
126
As a trend towards patient hypoxemia is indicated, blood samples should be
analyzed by laboratory instruments to completely understand the patient’s
condition.
⚫ The Pulse Oximeter is to be operated by qualified personnel only.
This manual, accessory directions for use, all precautionary information, and
specifications should be read and understood before use.
⚫ Electric shock hazard. Do not open the pulse oximeter cover except to replace the
battery of the Handheld unit.
Only a qualified operator may perform maintenance procedures specifically
described in this manual. Refer servicing to Masimo for repair of this equipment.
⚫ As with all medical equipment, carefully route patient cabling to reduce the
possibility of patient entanglement or strangulation.
⚫ Do not place the pulse oximeter or accessories in any position that might cause it
to fall on the patient.
Do not lift the pulse oximeter by the power cord or any other cable.
⚫ Interfering Substances: Carboxyhemoglobin and Methemoglobin may erroneously
increase readings.
The level of increase is approximately equal to the amount of carboxyhemoglobin
present. Dyes, or any substance containing dyes, that change usual blood
pigmentation may cause erroneous readings.
⚫ Elevated levels of Methemoglobin (MetHb) will lead to inaccurate SpO2
measurements.
⚫ Severe anemia may cause erroneous SpO2 readings.
⚫ Do not use the pulse oximeter or oximetry sensors during magnetic resonance
imaging (MRI) scanning.
Induced current could potentially cause burns. The pulse oximeter may affect the
MRI image, and the MRI unit may affect the accuracy of the oximetry
measurements.
⚫ If using pulse oximetry during full body irradiation, keep the sensor out of the
irradiation field.
⚫ If the sensor is exposed to the irradiation, the reading might be inaccurate or the
unit might read zero for the duration of the active irradiation period.
⚫ For home use, ensure that the pulse oximeter’s alarm can be heard from other
rooms in the house especially when noisy appliances such as vacuum cleaners,
dishwashers, clothes dryers, televisions, or radios are operating.
⚫ Always remove the sensor from the patient and completely disconnect the patient
from the pulse oximeter before bathing the patient.
⚫ Do not place the pulse oximeter where the controls can be changed by the patient.
⚫ Do not place the pulse oximeter face against a surface. This will cause the alarm to
be muffled.
