The Masimo Rad-57 is the world’s most versatile handheld oximeter with a rugged lightweight design ideal for field or hospital settings.

The Rad-57 requires no user calibration and does not need patient cooperation or consciousness. This is a great replacement for existing handheld pulse oximeters. You can get factory-ordered options or field-installed software upgrades to continuous monitoring and spot check measurements of SpHb, SpOC, SpMet and PVI.

Key Features:

  • Helps clinicians reduce the risk of misdiagnosing unsuspected carbon monoxide poisoning
  • Assists clinicians in detecting potentially life-threatening acquired methaemogloninaemia
  • Accurate SpO2 and pulse rate measurements during the most difficult clinical conditions, including during patient motion and conditions of low peripheral perfusion motion
  • Perfusion Index (PI) indicates arterial pulse signal strength and may be used by clinicians to help diagnose during low perfusion
  • User may programme default power-up settings Delivers more than 8 hours of continuous monitoring of SpCO, SpMet, SpO2, Pulse Rate, and Perfusion Index
  • FastSat tracks rapid changes in arterial O2 with unmatched fidelity
  • SmartTone™ beeps in sync with pulse, even under patient motion conditions
  • Up to 72 hours of trending memory of SpCO, SpMet, SpO2, Pulse Rate, and Perfusion Index
  • Sensitivity options of APOD, Normal and MAX provide flexibilty to support a range of clinical applications


  • More than 100 independent and objective studies demonstrate Masimo SET provides the most reliable oxygen saturation (SpO2) and pulse rate (PR) measurements under challenging clinical conditions, including patient motion and low peripheral perfusion. 
  • Masimo rainbow technology analyzes multiple wavelengths of light to measure. 
  • Masimo SET measurements, total hemoglobin (SpHb), carboxyhemoglobin (SpCO), methemoglobin (SpMet), and oxygen content (SpOC™). 
  • Pleth Variability Index (PVI) is a breakthrough measurement that may help clinicians noninvasively and continuously assess fluid status of patients.

Ask a Question

There is often confusion about how freight works and how lift gate deliveries work. Freight is used when shipments are 120 lb+ or for oversized equipment. Our standard Free Shipping option for freight deliveries is curbside, which is to a delivery to a Commercial Address and does not include a liftgate. If your order is to be shipped freight, you will have the option to specify whether the item will be delivered to a Residential, Limited Access, or Commercial address. If there is no option for Residential, Limited Access, or Commercial delivery, then the cost of this is included in the price.

We also recommend adding the optional Liftgate for all deliveries to locations without a loading dock or forklift.

  • Freight Delivery Location - This option specifies whether the delivery location is a Residential, Limited Access, or Commercial address. 
    • Residential - The fact that a business is being operated from a location does not qualify it as a commercial address. Any business being operated from a home, apartment, or other dwelling where people live on the premises is considered to be a residential address. In most cases, our freight carrier will contact you to make an appointment before delivery is attempted to a residential address.
    • Limited Access - Locations where deliveries are restricted, limited, or very far from a distribution center. Examples Include:
      • Place of Worship
      • Restricted Areas - Secure Research Facilities, Military Bases/Installations, Correctional Facilities, Government Buildings
      • Farms, Ranches, and Rural Areas
      • Recreational Areas - Camps, Parks, Fairs, Carnivals, etc.
      • Individual Storage Units
      • Sites - Construction, Mines
      • Schools and Universities
      • Commercial establishments not open to the walk-in public during normal business hours
    • Commercial - These addresses are those defined by our freight carriers and/or zoned by local municipalities as commercial sites. Typically these addresses are zoned as commercial real estate. Most commercial sites have tractor-trailer access and a loading dock.
  • Freight Liftgate - A lift gate is just a hydraulic lift that is attached to the back of a truck that can lower freight to ground level.

    Freight carriers prevent their drivers from assisting with the unloading of heavy equipment other than using a liftgate to ground level.  We highly recommend any delivery address without a loading dock, select this option. However, please know that for certain very long items, such as Kennels over 6' in length, a Liftgate will not be able to bring the entire order down to ground level. Please have the necessary manpower available to receive your items with limited delay to the driver.
