- MD20 lengths: The 5 ft version is the 4072 and the 4 ft EMS version is the 4792.10
- Cable life: X-Cal technology provides up to 17,520 hours of patient monitoring time, equal to two years of round-the-clock use.2

Frequently Asked Questions:
Is the Masimo 4073 a LIFEPAK 15 or Zoll X Series SpO2 cable?
Yes. Stryker sells it as 11996-000511 for the LIFEPAK 15, and Zoll sells it as 8000-001702 for the X Series and X Series Advanced.34 The UPC on Stryker's store listing, 00843997009744, is the 4073's device identifier, which ties the Stryker number to this Masimo part.85
Which sensors work with the Masimo 4073 MD20-12 cable?
Any sensor with the RD15 connector: RD SET, RD rainbow SET-2, RD rainbow 4λ, RD rainbow 8λ SpCO and LNCS-II rainbow 8λ SpCO.1 The 8λ SpCO sensors, such as the 4037 and 4067, add SpCO and SpMet; an RD SET sensor such as the 4050 reads SpO2 and pulse rate.71 Sensors with the M15 connector, including rainbow R-series and M-LNCS, need an RC cable such as the 4481.1
Is the Masimo MD20-12 (4073) the same cable as the M20-12 (4257)?
No. The 4073 is the RD rainbow SET MD20-12 and the 4257 is the RD Rainbow SET M20-12, each in its own series.5 The MD20 and the M20 are separate 20-pin rainbow cable series, each in 5 ft and 12 ft.6 Read the model number on the box before you order; this page is the 4073.
Can I use the Masimo 4073 on a LIFEPAK 35?
As listed, no. Stryker's LIFEPAK 35 guide does not carry 11996-000511; it lists the RD patient cables 11996-000458 (5 ft) and 11996-000457 (12 ft) and the RD EMS cable 11997-000298 (4 ft).9 The 4798 is that EMS cable, a 25-pin right-angle RA25-04.910
Does the Masimo 4073 show SpCO and SpMet on a LIFEPAK 15?
Yes, when an RD rainbow 8λ SpCO or LNCS-II rainbow 8λ SpCO sensor is on the cable, the monitor has rainbow SET 7.1 or higher and SpCO and SpMet are enabled.21 Stryker's 02/2025 LIFEPAK 15 guide lists 11996-000511 beside the rainbow sensors 11996-000515 to -000520.3 An RD SET sensor on the same cable reads SpO2 and pulse rate only.
Is there an extension cable for the Masimo 4073, or should I buy the 12 ft length?
Masimo makes the RD SET EXT-4 extension for RD and RD rainbow SET cables, and the sensor, cable and extension together must not exceed 15 ft.11 A 12 ft cable with a 3 ft sensor already reaches 15 ft, and the length table lists no 6 ft sensor with a 12 ft cable.12 The 4073 is the reach option; shorter cables leave room for an extension.
When should I replace the Masimo 4073?
Replace it when the monitor shows a replace cable message, when a low SIQ message keeps appearing across consecutive patients after the monitor's low SIQ steps, or when the 17,520 hours of X-Cal monitoring time are used up.213 On some older monitors a replace sensor message can point to the cable.2
