to the serial port. Leakage current must not exceed 100 microamperes.
Connect the oximeter only to a three-wire, grounded, hospital-grade receptacle.
The three-conducting plug must be inserted into a properly wired three-wire
receptacle is not available, a qualified electrician must install one in accordance
with the governing electrical code.
Do not under any circumstances remove the grounding conductor from the power
plug.
Do not use extension cords or adapters of any type. The power cord and plug must
be intact and undamaged.
If there is any doubt about the integrity of the protective earth conductor
arrangement, operate the oximeter on internal battery power until AC power
supply protective conductor is fully functional.
To ensure patient electrical isolation, connect only to other equipment with
electrically isolated circuits.
Do not connect to an electrical outlet controlled by a wall switch or dimmer.
As with all medical equipment, carefully route patient cabling to reduce the
possibility of patient entanglement or strangulation.
Do not place the monitor or external power supply in any position that might
cause it to fall on the patient. Do not lift the monitor by the power supply cord or
patient cable; use only the handle on the monitor.
Carboxyhemoglobin may erroneously increase readings. The level of increase in
approximately equal to the amount of carboxyhemoglobin present. Dyes, or any
substance containing dyes, that change usual arterial pigmentation may cause
erroneous readings.
Do not use the MS board pulse oximeter or Masimo oximetry sensors during
magnetic resonance imaging (MRI) scanning. Induced current could potentially
cause burns. The MS board pulse oximeter may affect the MRI image, and the MRI
unit may affect the accuracy of the oximetry measurements.
Consult IEC 60601-1 for system interconnection guidance. The specific
requirements for system interconnection are dependent upon the device
connected to the MS board pulse oximeter and the relative locations of each
device from the patients, and the relative location of the connected device to the
medically used room containing the MS board pulse oximeter. In all circumstance
the MS board pulse oximeter must be connected to a grounded AC power supply.
The MS board pulse oximeter is referred to as an IEC 60601 F device in the
summary of situation table contained in IEC 60601-1.
