Product Description and Features

Product Description

Masimo W1® is a wearable device that continuously tracks health data to better understand your general state of health and promote healthier lifestyle decisions. The Masimo W1 is compatible with the Masimo Health app where users can access, track and trend their health data.

Features

Key features of Masimo W1 include:

  • Masimo SET+™ technology.
  • Bluetooth® LE for the wireless communication.

The Masimo W1® provides these measurement features:

Oxygen Level (SpO 2 **) *| Oxygen levels in your blood, which can change with heart and lung function, activity, and altitude.
---|---
Pulse Rate (PR)| How often the heart pushes blood through your body, which can change with general health, physical activity, and with your mental or emotional state (e.g., stress, anxiety).
Pulse Rate Variability (PRV)| The changes in your pulse rate that can show how consistently your blood is being pushed through your body even under exercise or stress.
Pleth Variability Index (PVi)| A calculation based on the changes in your perfusion index, which may be affected by your fluid volume during your respiration cycle and can increase with lower fluid levels.
Perfusion Index (Pi)| A calculation of the relative strength of your pulse, which changes based on your circulation. The changes in your pulse rate that can show how consistently your blood is being pushed through your body even under exercise or stress.
Heart Rate (HR)| The number of times the heart beats in a minute, based on electrical signals.
Hydration Index (Hi)**| An index calculated to reflect your relative level of hydration; studies have shown that optimal hydration can improve sleep quality, cognition, mood, and more.

  • Arterial Oxygen Saturation

* Arterial Oxygen Saturation

WARNING: Always consult your physician regarding clinical decisions. Do not rely on the readings for medical decisions. Before use, read the following carefully.

Safety Warnings

WARNING: Do not use if it appears damaged or if you think it is damaged. Damage to the device can result in exposed sharp edges that may cause harm.
WARNING: Do not adjust, repair, open, disassemble, or modify the Masimo W1. Damage to the device may result in degraded performance and/or injury.
WARNING: Do not use in areas filled with flammable gases: such as anesthetics, oxygen, oxygen-enriched environments, or nitrous oxide to prevent risk of fire.
WARNING: Keep Masimo W1 away from small children. Small items may become a choking hazard.
Note: Use and store as directed in the Specifications section in this manual.

Performance Warnings

WARNING: Do not self-diagnose or self-medicate based on the measurements. Always consult your doctor regarding clinical decisions.
WARNING: See Risk and Benefit Section for information on limitations and ways to get the most accurate readings.
WARNING: Do not use Masimo W1 as an apnea monitor. Oxygen changes may be delayed from when your breathing actually stops.

WARNING: The Masimo W1 may not fully charge if the room is too hot.
WARNING: Check the fit of the watchband periodically. Avoid wearing the Masimo W1 too loose or too tightly to avoid inaccurate readings or pressure injury.
WARNING: Keep electronics with communication capabilities greater than 30 cm (12 inches) to any part of the Masimo W1. Otherwise, degradation performance could result.
CAUTION: When using with a smart device, keep both devices within the recommended range of each other. See Specifications for details. Moving outside of this range may cause a loss in connection.
CAUTION: Do not place the Masimo W1 near electrical equipment that may affect the device, preventing it from working properly.
CAUTION: Failure to charge Masimo W1 promptly after a Low Battery notification message may result in the device shutting down.
CAUTION: To establish and maintain the minimum Quality of Service of the Masimo W1, the keep the Masimo W1 within ~7 m (~23 ft.) line of sight to the smart device App.
CAUTION: Move the devices away from sources that may interfere with Bluetooth connection. The presence of other devices that may create radio frequency interference (RFI). This may result in loss of Quality of Service. Example devices that cause RFI are other smart devices, devices with remote controls, and baby monitors.
Note: All batteries lose capacity with age, thus the amount of run time at Low Battery will vary depending upon the age of the battery.
Note: A functional tester cannot be used to assess the accuracy of the Masimo W1.

HR Performance

WARNING: Make sure the Masimo W1 makes good contact with your wrist and your finger. Poor contact can result in no or incorrect readings.
WARNING: Avoid wearing watch over compromised skin, excessive hair, or scar tissue, as this may result in incorrect readings.
WARNING: Pacemakers that create fusion beats (pace pulse on top of the QRS complex) may not be detected by Masimo W1.
WARNING: HR reading can be affected by the following:

  • Poor electrode contact.
  • Conditions that may increase skin impedance (e.g., dry skin).
  • Weak heart signals.
  • Excessive movement.
  • Electrode or electrodes placement over skin injuries or hair.
  • Abnormal heart rhythms due to physiological conditions or induced through external factors (e.g., cardiac arrhythmias, ventricular tachycardia/fibrillation, seizures etc.).
  • EMI radiation interference.
  • Pacemakers
Cleaning and Service Warnings

WARNING: The following can cause damage that may impact the performance of your Masimo W1:

  • Do not attempt to sanitize or sterilize using heat, steam, boiling or similar means.

Electromagnetic Immunity

Note 1 : At 80 MHz and 800 MHz, the higher frequency range applies.

Note 2 : These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.

Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the Equipment is used exceeds the applicable RF compliance level above, the Equipment should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the Equipment.

(c) As an alternative to FM modulation, 50% pulse modulation at 18 Hz may be used because while it does not represent actual modulation, it would be worst case.

Recommended Separation Distances

Recommended separation distances between portable and mobile RF communications equipment and the Masimo W1.

Rated maximum output power of transmitter [W]| Separation distance according to frequency of transmitter [m]
80 MHz to 2.7 GHz
0.01| 0.06
0.1| 0.19
1| 0.6
10| 1.9
100| 6
For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.

Note: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.

Cleaning, Disinfecting and Service

The following chapter contains information about cleaning, battery operation, performance verification, service, repair, and warranty.

Cleaning Masimo W1 and Charger

CAUTION: Do not immerse Masimo W1 in any liquid.
The surfaces of Masimo W1 have been tested to be chemically resistant to the following disinfectants/solutions:

  • 70% Isopropyl Alcohol
  • CaviWipes™

To clean Masimo W1, follow the instructions below:

  1. Use a soft-bristle, nylon brush wet with DI water and gently brush along the grooves and crevices of the body to loosen debris before cleaning.
  2. Use one CaviWipe or a 4” x 4” gauze pad saturated with 70% IPA to wipe the surfaces twice or until the surfaces are free of any visible residue.
  3. Use a second soft-bristle, nylon brush with thin brush head wet with 70% IPA and gently brush along the grooves and crevices of the body at least twice.
  4. Use a second CaviWipe or a second 4” x 4” gauze pad saturated with 70% IPA to wipe the surfaces twice or until the surfaces are free of any visible residue.
  5. When using CaviWipes, use a 4” x 4” gauze pad saturated with DI water to wipe the surface once.
  6. Allow the Masimo W1 device to dry thoroughly before using again

CAUTION : Never saturate Masimo W1 completely with any disinfection solution.
