Product Highlights:

  • Ear concha placement: The emitter limb rests in the hollow of the inner ear, the detector limb lies flat behind the ear, and the notch fits under the smallest part of the lobe. It is not for any other site.1
  • Monitor requirement: Runs only on Masimo SET MS-2000 (version 4.8 or higher) or rainbow SET MX monitors; an LNC cable alone is not enough. Validated on the Radical-7, Rad-8, Rad-5, Rad-87 and Rad-57.1
  • Accuracy: SpO2 2.5% Arms and pulse rate 3 bpm with Masimo SET, at no motion and in low perfusion.1
  • Single patient use: Discard it after one patient. It is not for prolonged use at one site; for extended monitoring move it to the opposite ear.1
  • Contraindications: Foam rubber or adhesive tape allergy, a pierced ear, and redness, swelling, infection or broken skin at the site, including behind the ear.1

  • Clinics and Urgent Care: On monitors that meet the E1's software requirement, exam-room and urgent care staff check patients with finger deformities or limited digit access at the ear.112

Frequently Asked Questions:

Which monitors work with the Masimo 2918 LNCS E1, and what software does it need?

The monitor must contain Masimo SET MS-2000 (version 4.8 or higher) or rainbow SET MX technology; an LNC cable alone is not enough.19 Masimo validated the E1 on the Radical-7, Rad-8, Rad-5, Rad-87 and Rad-57.1 Zoll lists the 2918 for the X Series, X Series Advanced and Propaq.8 For a LIFEPAK 15, send us the monitor and cable model and we confirm the fit.

Does any LNC cable work with the Masimo 2918, or does it need something special?

No special cable. The 2918 uses the same LNC and Red LNC cables as other LNCS sensors, chosen by the monitor port: the Red LNC-04 (2055) or Red LNC-10 (2056) on a 20-pin port, the LNC-4 (2017) or LNC-10 (1814) on a 14-pin port.23 The cable is not the limit: on a monitor without the required board the E1 may give no reading.1 M-LNC, rainbow RC and RD cables do not take it.9

What are the Stryker/Physio-Control and Zoll numbers for the Masimo 2918?

11171-000067 is the Stryker/Physio-Control number, and Stryker's store descriptor for it reads REF 2918.47 8000-000456 is the Zoll number, listed as the single patient ear sensor, LNCS E1, box of 10.8 Do not confuse 11171-000067 with Stryker's M-LNCS E1, 11171-000066, which is the 2919.

Pick the 2918, 2919 or 4015 E1: which Masimo E1 matches my monitor cable?

Match the cable. An LNC or Red LNC cable takes the 2918. An M-LNC or rainbow RC cable takes the 2919, Stryker 11171-000066. An RD or RD rainbow SET cable takes the 4015, Stryker 11996-000507.9 All three are single-patient-use ear sensors for patients over 30 kg.1

Is the Masimo 2918 an ear clip or an adhesive sensor, and how do I place it?

Neither: the ear holds it. Pull the emitter and detector limbs apart, set the emitter limb (star forward) in the hollow of the inner ear, lay the detector pad flat behind the ear, and fit the notch under the smallest part of the lobe. Stick the cable's anchor tab to the anchor pad on the shoulder skin, not clothing, and do not tape the sensor.1

Can the Masimo 2918 go on a pierced ear or a small ear?

Not over a piercing. It also cannot go on skin that is red, swollen, infected or broken, or on a patient allergic to foam rubber or adhesive tape.1 If the inner ear cannot hold the emitter limb without touching the tragus or crus of helix, use a digit sensor instead, such as the 1863 DCI.1

Is the Masimo 2918 reusable, and how long can it stay on one ear?

No. It is single patient use: it stays with one patient and is discarded. It is not for prolonged use at one site and carries no fixed hour limit; move it to the opposite ear for extended monitoring, or use a Masimo adhesive digit sensor if it cannot be moved. Check the site frequently, as often as every hour on poorly perfused patients.1

Is this a genuine Masimo 2918?

Yes. We are an authorized Masimo distributor. Every Masimo 2918 ships new in its original Masimo packaging.

How fast does the Masimo 2918 ship?
