Masimo W1®

Daily Monitoring

Daily Monitoring

We recommend cleaning your Masimo W1 frequently to remove any dirt or debris that may build up during daily wear.

To clean your Masimo W1, use a soft-bristle, nylon brush to gently brush along the grooves and crevices of the watch and band to loosen debris before cleaning. Wipe surfaces with a gauze pad saturated with 70% isopropyl alcohol until your Masimo W1 is free of residue.

Do not immerse your Masimo W1 in any liquid.

Oxygen level (SpO2)*
Oxygen levels in your blood 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).

Breaths per minute (RRp®)
The number of breaths you take in a minute, based on the pleth waveform; respiration rate can change with your general health condition, physical activity, or mental or emotional state.

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.

Activity (Steps)
The level of physical activity captured due to motion, represented in steps count.

Heart rate (HR)
The number of times the heart beats in a minute, based on electrical signals.

Perfusion Index (Pi)
A continuous calculation of the relative strength of the pulse, which changes based on circulation.

Pulse Rate Variability (PRV)
A continuous measurement of the variation in time between each pulse. The PRV changes with exercise and stress, including illness.

Atrial Fibrillation
An irregular heartbeat detection based on the ECG waveform.
