OxyCon - Oxygen Concentration

This datafield displays % concentration of oxygen in air at your present elevation using the ambient air pressure sensor measurement. For watches without an ambient air pressure sensor, GPS altitude is used. # Features * Setting option to display as a % of nominal oxygen concentration at sea level (displayed as Rel. O2) At sea level under nominal conditions it would read 100%. * Setting option to compensate for relative humidity using Garmin weather data. (As humidity increases, O2 concentration decreases) # FULL Version Features * Saves O2 Concentration, ambient pressure and SpO2 trends to FIT file for viewing in the Garmin Connect app. (Each parameter individually selectable) * Option to display blood oxygen saturation (SpO2) * Determines VO2max adjustment for altitude and saves this for viewing with the activity in Garmin Connect. For example, if the VO2max adjustment value is 5%, then the reported VO2max should be further multiplied by 1.05 to estimate your VO2max at sea level.

Version 1.9.1 Added support for the Forerunner 70 and 170 models. Version 1.9.0 FULL Version only change: Added optional low O2 concentration and SpO2 alerts, with customizable threshold levels (requires a Garmin model with Connect IQ version 3.2.0 or higher). Version 1.8.3 Added support for the D2 Air X15 and D2 Mach 2. Version 1.8.2 Added support for Venu 4 models. Version 1.8.1 Added support for the Fenix 8 Pro, and Edge 550/850. Version 1.8.0 PRO Version only change: Added option to read SpO2 from the sensor history buffer instead of the value provided by the activity. This was added to because of suspected issues with the value provided by the activity. Version 1.7.0 Added back missing selection of SpO2 for display. Added support for omitted models Approach S50, and some Edge models. Version 1.6.3 Added support for the Venu X1. Version 1.6.2 Added support for Forerunner 570/970 models. Version 1.6.1 Added support for the Vivoactive 6. Version 1.6.0 FULL version only change: Added option to display blood oxygen saturation (SpO2). Version 1.5.12 Added support for the Descent G2. Version 1.5.11 Added support for the instinct 3 series. Version 1.5.9, 1.5.10 Added support for the Enduro 3 and Fenix 8 series. Version 1.5.8 Added support for Forerunner 165 models. Version 1.5.7 Added support for the Descent Mk3 43mm models. Version 1.5.6 Added support for the Fenix 7 Pro Solar. Version 1.5.5 Added support for the Descent Mk3 model. Version 1.5.4 Added support for the Fenix 7X Pro Solar. Version 1.5.3 Added support for Vivoactive 5. Version 1.5.2 Added support for Edge 840. Version 1.5.1 Added support for Venu 3 series. Version 1.5.0 FULL Version only change: Calculated and saved VO2max adjustment for altitude [%] to the FIT file for viewing in the Activity summary in Garmin Connect. For example, if the VO2max adjustment value is 5%, then the reported VO2max should be further multiplied by 1.05 to estimate your VO2max at sea level. For clarity, the app will not automatically apply this compensation to the reported VO2max. Version 1.4.0 FULL Version only change: Corrected crash. Version 1.3.0 Added paid version features: Saves O2 Concentration, ambient pressure and SpO2 trends to FIT file for viewing in the Garmin Connect app. (Each parameter individually selectable) Version 1.2.7 Added support for Epix 2 PRO and Fenix 7 PRO models. Version 1.2.6 Added support for Approach S70. Version 1.2.5 Added support for Instinct 2X Solar. Version 1.2.4 Added support for the Forerunner 265 and 965 series.

Updated driver for Captain Marvel, First Avenger, Rey, Darth Vader, Vivoactive 4S, Vivoactive 4. Version 1.1.1 Added support for Edge devices. Version 1.1.0 For watches without an ambient air pressure sensor, GPS altitude is used for the calculation. This is slightly less accurate because barometric pressure may be higher or lower than nominal.
