►FAQ
What patient populations is the 4054 sensor suitable for?
A: It is a universal/multisite sensor suitable for all patient demographics. By using the appropriate single-patient attachment accessories, it can be safely used on adults, pediatric patients, infants, and neonates (weighing > 1 kg).
Why is my monitor showing an error or failing to recognize the 4054 sensor?
A: This is typically caused by one of the following reasons:
Interface Mismatch: The 4054 uses the Masimo RD SET standard connector. If your monitor uses older LNOP or LNCS technology ports, it will not connect directly without an appropriate adapter cable.
Damage or Debris: Inspect the cable, pins, and connector plug for physical damage, wear, or dirt/moisture buildup.
Compatibility Issues: Ensure you are using genuine Masimo equipment or that your monitor’s embedded Masimo board is properly authorized.
