74 Patient monitoring Connex Spot Monitor
WARNING Inaccurate measurement risk. Misapplied sensors or sensors
that become partially dislodged may cause either over or under reading of
actual arterial oxygen saturation.
WARNING Inaccurate measurement risk. Venous congestion may cause
under reading of actual arterial oxygen saturation. Therefore, assure proper
venous outflow from monitored site. Sensor should not be below heart
level (e.g. sensor on hand of a patient in a bed with arm dangling to the
floor).
WARNING Inaccurate measurement risk. Use only Nonin sensors and
accessories on Nonin-equipped monitors.
WARNING The pulsations from intra-aortic balloon support can increase
the pulse rate displayed on the monitor. Verify the patient's pulse rate
against the ECG heart rate.
WARNING Patient injury risk. Do not attempt to reprocess, recondition, or
recycle any sensors or patient cables. Doing so might damage electrical
components.
WARNING Patient injury risk. The pulse oximeter is NOT intended for use
as an apnea monitor.
WARNING Patient injury risk. To avoid cross contamination only use
Masimo single use sensors on the same patient.
WARNING Patient injury risk. Do not use tape to secure the sensor to the
site; this can restrict blood flow and cause inaccurate readings. Use of
additional tape can cause skin damage or damage the sensor.
WARNING Unless otherwise specified, do not sterilize sensors or patient
cables by irradiation, steam, autoclave or ethylene oxide. See the cleaning
instructions in the Directions for use for the Masimo re-useable sensors.
WARNING Patient injury risk. Loss of pulse signal can occur when the
patient has severe anemia or hypothermia.
WARNING SpO2 is empirically calibrated in healthy adult volunteers with
normal levels of carboxyhemoglobin (COHb) and methemoglobin (MetHb).
WARNING High-intensity extreme lights, such as pulsating strobe lights,
directed on the sensor may not allow the pulse oximeter to obtain vital sign
readings.
WARNING Pulse rate measurement might not detect certain arrhythmias
because it is based on the optical detection of a peripheral flow pulse. Do
not use the pulse oximeter as a replacement or substitute for ECG-based
arrhythmia analysis.
WARNING Use the pulse oximeter as an early warning device. As you
observe a trend toward patient hypoxemia, use laboratory instruments to
analyze blood samples to better understand the patient's condition.
