Quick answer. This hub matches the right MedLinket accessory to each clinical scenario on a Philips IntelliVue MX-series fleet (MX400 through MX850). The decisive factor is never the chassis model — it is the SpO2 module label on the back of the monitor, which can be native Philips FAST, Masimo SET, or Nellcor OxiMax. Below you'll find the selection rule, accessory recommendations by clinical unit, and a complete directly-linked accessory list by family (SpO2, ECG, NIBP, IBP, temperature, EtCO2).
What determines MX-series compatibility — module, not chassis
The single most important framing for accessory ordering on the MX-series:
A Philips IntelliVue MX500 can ship with any of three SpO2 module configurations:
| Module label | What it means | Sensor connector you need |
|---|---|---|
| Philips FAST SpO2 (native) | Philips's own algorithm | Philips 8-pin |
| Masimo SET | Licensed Masimo algorithm | Masimo LNCS or M-LNCS |
| Nellcor OxiMax | Licensed Nellcor algorithm | Nellcor OxiMax 9-pin |
The same MX500 chassis with three module configurations needs three different sensor families. Photograph the SpO2 module label before ordering. If the label is worn, the patient cable identifies the module. This rule applies across every accessory family — SpO2, ECG, NIBP, IBP, temperature, EtCO2. Unsure which connector you have? See the Philips SpO2 connector identification guide.
Models covered by this hub
| Model | Typical use | Modules commonly fitted |
|---|---|---|
| MX400 / MX430 | General ward, step-down, mid-acuity | SpO2, 3/5-lead ECG, NIBP, temperature |
| MX450 | General ward, telemetry, mid-acuity | SpO2, ECG, NIBP, temperature; optional IBP |
| MX500 / MX550 | ICU, step-down, OR | SpO2, 5/12-lead ECG, NIBP, IBP, temperature, optional EtCO2 |
| MX600 / MX700 | ICU, OR | SpO2, 12-lead ECG, NIBP, multi-IBP, temperature, EtCO2 |
| MX750 / MX800 / MX850 | ICU, OR, anesthesia | Full multi-parameter; cardiac output, gas analyzer, depth-of-anesthesia optional |
Accessory families are shared across the entire MX-series — a Philips FAST SpO2 sensor for an MX400 is the same sensor that connects to an MX850, provided both monitors carry Philips FAST modules.
Reading path by clinical scenario
Use the scenario that matches your unit. Each gives the recommended accessory configuration and the substitutions to avoid.
Operating room
Typical monitors: MX550, MX600, MX700, MX750, MX800, MX850. Long procedures, electrosurgical interference, fluid contamination, multiple IBP lines, continuous EtCO2.
- SpO2: reusable adult clip on every table — M1191A compatible (Philips FAST module) or Masimo LNCS compatible (Masimo SET module). Reusable is the right choice — cleaning between cases is part of the OR workflow.
- ECG: 5-lead or 12-lead reusable trunk cable plus disposable electrodes.
- NIBP: reusable adult cuff plus quick-connect hose.
- IBP: single-use or reusable pressure transducer sets — often 3–4 lines for cardiac surgery.
- EtCO2: mainstream or sidestream depending on the airway.
Avoid: pediatric clips on adult patients (signal dropout); disposable adhesive SpO2 sensors (the adhesive tolerates prep antiseptics poorly); legacy cables without modern shielding (electrosurgical interference is severe in OR).
Adult ICU
Typical monitors: MX450, MX500, MX550, MX600, MX700. 24/7 monitoring, frequent line changes, central-station integration, transport in and out of the unit.
- SpO2: a mix of reusable clips for stable patients and disposable adhesive sensors for patients with skin concerns or hand edema. The reusable M1191A compatible is the workhorse.
- ECG: 5-lead reusable trunk cable with leadwires; disposable electrodes for daily change.
- NIBP: reusable cuffs in adult and large-adult sizes; quick-connect hoses.
- IBP: single-use transducer sets are standard for infection-control reasons.
Avoid: leaving the same SpO2 sensor on the same finger for a full shift (rotate every 2 hours); using bridge-inventory adapter cables for any patient who could decompensate — the algorithm mismatch at low perfusion is documented in the Adapter Lab study, and ICU patients can decompensate without warning.
NICU
Typical monitors: MX450 or MX500, often with a Masimo SET module for its lower-noise neonatal algorithm. Smallest patients, most fragile skin, longest continuous monitoring, phototherapy environments.
- SpO2: M1193A compatible neonatal wrap (under 3 kg) or M1195A infant strap (3–10 kg) for Philips FAST modules; LNCS Neo-L / Inf equivalents for Masimo SET modules. Finger clips are not safe on neonates.
- ECG: disposable electrodes formulated for neonatal skin, 3-lead configuration.
- NIBP: neonatal cuffs in sizes 1–5 per patient weight band.
Avoid: any adult or pediatric finger clip on a neonate; adhesive sensors with non-neonatal adhesives; leaving a sensor at one site beyond the 2-hour interval. Site rotation every 2 hours with skin inspection is the primary defence against medical-device-related pressure injury (MDRPI) — no sensor design eliminates this requirement.
Pediatric ward / PICU
Typical monitors: MX450, MX500. Patients spanning 10 kg to 60 kg, frequent transitions between weight-based sensor categories.
- SpO2: M1192A compatible pediatric clip for 10–50 kg; transition to M1191A adult clip above 50 kg. Stock both.
- ECG: 5-lead reusable trunk, pediatric-sized leadwires, pediatric-formulated electrodes.
- NIBP: pediatric cuffs in multiple sizes; transition sizes as the patient grows.
Avoid: scaled-down adult sensors marketed as pediatric (the spring tension is wrong); leaving an M1192A clip on a patient who has grown into adult-sized fingers (signal dropout).
Patient transport
Typical monitors: MX400, MX450, MX500 portable, or the X3 telemetry head. Motion artifact, cable strain from bed rails and stretchers, brief but high-stakes monitoring.
- SpO2: reusable clip with a shorter cable to reduce strain; adhesive disposable sensors are sometimes preferred because they do not pop off with motion.
- ECG: pre-apply electrodes before transport rather than during.
- Cable management: clip the cable to the patient gown to reduce strain on connectors.
Avoid: long cables that catch in stretcher rails; bridge-inventory adapter cables — the algorithm mismatch at low perfusion is exactly the regime a transported patient can enter.
PACU (post-anesthesia care unit)
Typical monitors: MX400, MX450, MX500. Brief monitoring per patient but high throughput, frequent sensor swap.
- SpO2: reusable clips — throughput is high enough that disposable does not pay for itself, and short PACU stays build the rotation interval into the natural patient flow.
- ECG: 5-lead reusable, electrodes continued from the OR.
- NIBP: reusable adult cuff with quick-connect.
Avoid: skipping cleaning between patients in the rush of high throughput; failing to swap pediatric and adult sensors between consecutive patients of very different sizes.

Common procurement pitfalls — what we see in the field
After 20+ years and 2,000+ hospitals, the same five mistakes account for most avoidable returns:
- Ordering by chassis model instead of module label. A "Philips MX500" can have three different SpO2 modules. Always identify the module first — we will identify it from a photo if you cannot tell.
- Confusing Nellcor OxiSmart 7-pin with OxiMax 9-pin. Both shells look identical; the pin counts differ. See the DS-100A product page for identification detail.
- Confusing Masimo LNCS, M-LNCS and RD. All three are rectangular Masimo connectors; the keying differs. See the LNCS compatible product page.
- Using an adapter cable for permanent deployment rather than bridge inventory. Adapter cables solve the connector mismatch but not the algorithm mismatch — see the Adapter Lab study.
- Standardising on one sensor size across mixed-population units. Stock at least two sensor sizes per unit, more if the patient distribution warrants.
How to get a configuration review
If you are evaluating MX-series accessory inventory — for a new purchase, a fleet refresh, or a hospital-wide standardisation initiative — MedLinket offers a free configuration review for BMET departments. Send your monitor inventory (chassis model plus module type per monitor) and the clinical unit each monitor serves; we respond with a recommended accessory family per monitor, pitfall flags and an evaluation sample plan. There is no obligation to purchase.
Frequently asked questions
How do I tell which SpO2 module my MX monitor has?
Photograph the SpO2 module label on the back of the monitor. If the label is worn, the patient cable identifies it — a Philips FAST cable has an 8-pin monitor end; a Masimo cable plugs into a Masimo SET port; a Nellcor cable has the 9-pin OxiMax connector. We will identify the module from a photo within one business day.
Can one SpO2 sensor cover my whole MX fleet?
Only if every monitor in the fleet carries the same SpO2 module. If the fleet mixes Philips FAST and Masimo SET modules, you need two sensor families. Inventory the module per monitor before standardising.
Are MX-series accessories the same as MP-series accessories?
For most accessory families, yes — provided the module configuration matches. A Philips FAST SpO2 sensor works on an MP70 and an MX800 alike if both carry Philips FAST modules. See the MP-series hub for mixed-fleet planning.
