What to do if Masimo Rad-87 buttons fail to work when pressed?
If the buttons on your Masimo Medical Equipment are not responding, this could indicate an internal failure. Use the auxiliary power down method by pressing and holding the Sensitivity and Display buttons simultaneously. The equipment should be returned for service.
Why is Masimo Medical Equipment's battery run-time significantly reduced?
If the battery run-time of your Masimo Medical Equipment is significantly reduced, the battery may be low. Contact Technical Services or your local Masimo representative.
What to do when Masimo Rad-87 Medical Equipment shows 'Pulse Search' message?
If your Masimo Medical Equipment displays a 'Pulse Search' message, it means the instrument is searching for a pulse. If the device doesn't find a pulse within 30 seconds, disconnect and reconnect the sensor to the patient. If the search continues, try moving the sensor to a better-perfused site.
What causes low perfusion (PI Bar Turns Red) on Masimo Rad-87, and how to fix it?
If the Perfusion Index (PI) bar turns red on your Masimo Medical Equipment, it could be due to several reasons: using the wrong sensor type, a poorly perfused site, a sensor that's too tight, certain disorders (like hypothermia or anemia), or a damaged sensor. To address this, verify you're using the correct sensor and size for the patient. Check for restricted blood flow to the site and ensure the sensor isn't too tight. You can also try setting the unit to MAX sensitivity, warming the patient or sensor site, or moving the sensor to a better-perfused site.
How to turn on Masimo Rad-87 if it doesn't power on?
If your Masimo Medical Equipment is not powering on, connect the AC Power Cord to the Rad-87 and to an AC outlet. Ensure the AC Power Indicator light is on.
What to do if the Masimo Rad-87 Medical Equipment shows a 'Sensor Off' message?
To resolve a 'Sensor Off' message on your Masimo Medical Equipment, first, properly reapply the sensor to the patient and reconnect it to the unit or patient cable. If the sensor is damaged, replace it.
Why is Masimo Medical Equipment showing unexpected high SpCO reading?
If your Masimo Medical Equipment is showing an unexpectedly high SpCO reading, it could indicate a possible elevated methemoglobin level. Submit a blood sample for a laboratory CO-Oximetry test.
What to do if Masimo Medical Equipment has difficulty or no SpO, SpCO/ SpMmet/SpHb reading?
If your Masimo Medical Equipment is having difficulty obtaining or shows no SpO2, SpCO, SpMet, or SpHb readings, ensure the device is properly powered by connecting the AC power cord to the device and an AC outlet, verifying the AC power indicator light is on. Minimize motion at the monitoring site. Verify the 50/60Hz menu setting. Use the correct sensor and size for the patient. Shield the sensor from excessive or strobing light. The causes can be low battery, excessive motion, interference from line-frequency induced noise, inappropriate sensor or sensor size or excessive ambient or strobing light.
What causes 'Low SIQ' message on Masimo Rad-87?
A 'Low SIQ' message on your Masimo Medical Equipment can be caused by improper sensor type or application, excessive motion relative to perfusion, or a damaged/non-functioning sensor or cable. Check if blood flow to the site is restricted and ensure proper sensor placement. Try reapplying the sensor or moving it to a different site. If the issue persists, replace the sensor or cable.
