Name: OxyCon - Oxygen Concentration
Rating: 4.2 (9 reviews)
Author: Trudelta

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.

* Optional low O2 concentration and SpO2 alerts, with customizable threshold levels (requires a Garmin model with Connect IQ version 3.2.0 or higher)
