Zacurate 500C Elite Fingertip Pulse Oximeter review

The Zacurate 500C Elite adds the features a caregiver tends to want on top of the brand's basic 500DL. Zacurate lists an auditory alarm when SpO2 and pulse rate move beyond set limits, a beep for each detected pulse, a perfusion index and a plethysmograph waveform, all on a rotatable OLED screen with six display directions and adjustable brightness. The display range is 35 to 100%, with plus or minus 2% accuracy between 70 and 100%. The finger chamber is hypoallergenic, latex-free silicone, and the battery cover snaps off. It has no Bluetooth, so there is no history beyond what you write down, and it runs on AAA batteries. At $36.99 it costs almost as much as the iHealth Air, so the choice comes down to alarms on the device versus trends in an app.
