Masimo SET® Pulse Oximetry is the primary pulse oximetry technology at all top 10 U.S. hospitals (as of 2024) and monitors more than 200 million patients annually worldwide.
A peer-reviewed study found that Masimo SET® SpO2 achieved ARMS* accuracy of 1.37% in subjects with normal perfusion and 1.64% in subjects with low perfusion. The 4052 sensor maintains accuracy during conditions common in adult patients, including hypothermia, hypotension, and vasoconstriction.
Before Masimo SET® pulse oximetry, false alarm rates were high, often due to motion and low perfusion. With Masimo SET®, the rate of false alarms dropped by more than 80% while true alarm detection improved significantly—reducing alarm fatigue for clinical staff.
A peer-reviewed publication demonstrated that Masimo RD SET sensors had only a 0.15% difference in bias between dark- and light-skinned subjects—not clinically significant because pulse oximeters measure in whole numbers. RD SET accurately measured SpO2 for both Black and White subjects during normal and low perfusion.
A study conducted over 10 years on general floor patients being monitored with Masimo SET® while recovering from surgery found zero preventable deaths or brain damage from opioid-induced respiratory depression.
Masimo SET® pulse oximetry has been shown in over 100 independent clinical studies to outperform other pulse oximetry technologies, providing clinicians with the accuracy needed to make informed care decisions in challenging conditions.
The Masimo 4052 RD SET DBI sensor connects to monitors with Masimo SET® technology via an RD SET patient cable, including:
Requires Stryker RD SET patient cable (11996-000457 or 11996-000458)
Requires Zoll RD SET patient cable
This sensor requires connection to an RD SET patient cable for proper operation:
Continuous SpO2 monitoring for critically ill adults requiring ventilator support, sedation, or hemodynamic monitoring. The soft sensor design prevents pressure-related skin issues during extended ICU stays, making it ideal for patients monitored for days or weeks.
Extended monitoring following surgery, particularly for patients receiving opioid pain management. The comfortable design encourages patient compliance and reduces the need for sensor repositioning by nursing staff.
Transitional care monitoring where patients require continuous observation but are stable enough to transfer from ICU. The soft sensor provides reliable readings without the discomfort that can prompt patients to remove their monitoring equipment.
Overnight oximetry studies for sleep apnea evaluation in adults. The minimal pressure design ensures patient comfort throughout the night, improving data quality by reducing movement artifacts from patient adjustments.
Chronic condition monitoring for patients with COPD, heart failure, or other conditions requiring extended oxygen saturation surveillance. The reusable design provides cost-effective monitoring for facilities with high-acuity patient populations.
While clip sensors work well for short ED encounters, the soft sensor is preferred for patients awaiting admission who will require monitoring for hours. Quick application and removal also supports spot-checking needs.

The Masimo 4050 (DCI) is a rigid finger clip sensor, while the 4052 (DBI) is a soft sensor that wraps around the finger. Both are for adult patients over 30kg. The 4052 soft sensor provides greater comfort for extended continuous monitoring (ICU, post-op, sleep studies), while the 4050 clip is ideal for spot checks and shorter monitoring periods.
Yes, the Masimo 4052 is compatible with Stryker LIFEPAK 15, LIFEPAK 20e, and LIFEPAK 35 monitor/defibrillators when used with an RD SET patient cable (Stryker part numbers 11996-000457 for 12ft or 11996-000458 for 5ft cable).
Yes, the Masimo 4052 is compatible with Zoll X Series and X Series Advanced monitor/defibrillators when used with a Zoll RD SET patient cable.
RD SET (Red Diamond SET) and LNCS (Low Noise Cabled Sensors) are two different Masimo connector types. The 4052 uses RD SET technology and requires RD SET-compatible cables and monitors. LNCS sensors use a different connector and are not interchangeable with RD SET sensors. Always verify your monitor's compatibility before ordering.
The 4052 is designed for adult patients weighing more than 30kg (66 lbs). For pediatric patients weighing 10-50kg, we recommend the Masimo 4051 RD SET DCI-P pediatric sensor. Using the correct size sensor ensures optimal accuracy and patient comfort.
With proper care and cleaning, the Masimo 4052 reusable soft sensor typically lasts 6-12 months in clinical use. The 6-month warranty covers manufacturing defects. Sensor lifespan depends on usage frequency, cleaning practices, and handling.
Traditional clip sensors apply continuous pressure to the finger, which can cause discomfort, skin irritation, and potential pressure injuries during extended use. The soft sensor design provides minimal pressure while maintaining accurate readings, making it the preferred choice for ICU patients, post-operative monitoring, and any situation requiring monitoring for hours or days.
Yes, the Masimo 4052 sensor is made from non-rubber latex materials, making it safe for patients with latex allergies.
The 4052 requires an RD SET patient cable such as the Masimo 4103, Stryker 11996-000457/458, or Zoll RD SET cable. For use with the Rad-G Handheld Pulse Oximeter, a Masimo 4773 patient cable is required. The sensor is not compatible with LNCS or M-LNCS cables.
Clinical studies have demonstrated that Masimo RD SET sensors show only a 0.15% difference in accuracy between dark- and light-skinned subjects, which is not clinically significant. The sensor provides accurate SpO2 readings for patients of all skin tones, including during low perfusion conditions.
