Select a delivery device from Nasal Cannula, Face Mask, or Non-Rebreather Mask (NRBM) and adjust the flow rate slider to see the estimated FiO2 percentage update instantly on a clear, easy-to-read gauge. Features: • Three oxygen delivery devices with device-appropriate flow ranges • Instant FiO2 percentage estimate as you adjust flow rate • Low-flow safety alerts (e.g. CO2 rebreathing risk on face mask below 5 LPM) • Step-up suggestions when a device reaches its maximum flow rate • Quick-access links to clinical references (Medscape, Geeky Medics, Open Critical Care) For clinical reference only. This app is a quick-estimate tool and is not a substitute for professional clinical judgment, hospital protocol, or medical training. ## FiO2 Calculator Screenshots - [Screenshot 1](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/8b/3c/f0/8b3cf006-0320-4d18-d4eb-bedda28d8a6c/Simulator_Screenshot_-_iPhone_17_Pro_Max_-_2026-07-07_at_19.30.05.png/1320x2868.png) - [Screenshot 2](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/36/22/1e/36221e5b-e635-0fc6-5fe4-60f071c726b6/Simulator_Screenshot_-_iPhone_17_Pro_Max_-_2026-07-07_at_19.30.13.png/1320x2868.png) - [Screenshot 3](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/00/d6/fd/00d6fd1e-99af-483f-a2cc-646eb1f5072a/Simulator_Screenshot_-_iPhone_17_Pro_Max_-_2026-07-07_at_19.31.22.png/1320x2868.png) - [Screenshot 4](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/fe/2e/8f/fe2e8f3f-800e-519b-7181-6b206cab6e9b/Simulator_Screenshot_-_iPhone_17_Pro_Max_-_2026-07-07_at_19.30.19.png/1320x2868.png) - [Screenshot 5](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/5d/11/87/5d118766-6d42-d55a-ca62-266c308cc91a/Simulator_Screenshot_-_iPhone_17_Pro_Max_-_2026-07-07_at_19.30.27.png/1320x2868.png) - [Screenshot 6](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/dc/3e/47/dc3e47e8-4250-c2c0-bbf1-6eabf61b5019/Simulator_Screenshot_-_iPhone_17_Pro_Max_-_2026-07-07_at_19.31.29.png/1320x2868.png) - [Screenshot 7](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/a9/94/4c/a9944cb3-847c-695d-a2b6-1058879b40cf/Simulator_Screenshot_-_iPhone_17_Pro_Max_-_2026-07-07_at_19.30.44.png/1320x2868.png) - [Screenshot 8](https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/ac/a8/2c/aca82c14-854f-6c42-c6ac-66594e35ddf4/Simulator_Screenshot_-_iPhone_17_Pro_Max_-_2026-07-07_at_19.30.53.png/1320x2868.png) ## Apps Similar to FiO2 Calculator - [Fever Track: Body Temperature](https://apptail.io/app/fever-track-body-temperature-kwx/canada) - [Me+ Lifestyle Routine](https://apptail.io/app/me-lifestyle-routine-jYA/canada) - [MEDS: Pill & Injection Tracker](https://apptail.io/app/meds-pill-injection-tracker-MZR/canada) - [Vitamin — Log, Scan & Schedule](https://apptail.io/app/vitamin-log-scan-schedule-Mxrb/canada) - [Glowise: GLP-1 Tracker & Diary](https://apptail.io/app/glowise-glp-1-tracker-diary-ODiu/canada) - [MOHKW](https://apptail.io/app/mohkw-OMfv/canada) - [PeptPro: Controle de Peptídeos](https://apptail.io/app/peptpro-controle-de-peptideos-HXRz/canada) ## FiO2 Calculator Available In - [Armenia](https://apptail.io/app/fio2-calculator-GmPA/armenia) - [Argentina](https://apptail.io/app/fio2-calculator-GmPA/argentina) - [Belarus](https://apptail.io/app/fio2-calculator-GmPA/belarus) - [Canada](https://apptail.io/app/fio2-calculator-GmPA/canada) - [Czechia](https://apptail.io/app/fio2-calculator-GmPA/czechia) - [Germany](https://apptail.io/app/fio2-calculator-GmPA/germany) - [Dominican Republic](https://apptail.io/app/fio2-calculator-GmPA/dominican-republic) - [Ecuador](https://apptail.io/app/fio2-calculator-GmPA/ecuador) - [Egypt](https://apptail.io/app/fio2-calculator-GmPA/egypt) - [Croatia](https://apptail.io/app/fio2-calculator-GmPA/croatia) - [Kuwait](https://apptail.io/app/fio2-calculator-GmPA/kuwait) - [Nigeria](https://apptail.io/app/fio2-calculator-GmPA/nigeria) - [Saudi Arabia](https://apptail.io/app/fio2-calculator-GmPA/saudi-arabia) - [Singapore](https://apptail.io/app/fio2-calculator-GmPA/singapore) - [Slovakia](https://apptail.io/app/fio2-calculator-GmPA/slovakia) - [Suriname](https://apptail.io/app/fio2-calculator-GmPA/suriname) - [United States](https://apptail.io/app/fio2-calculator-GmPA/united-states) --- ## About AppTail [AppTail](https://apptail.io) is a mobile app intelligence platform providing app analytics, ASO (App Store Optimization) tools, keyword tracking, competitor analysis, revenue estimates, and review monitoring for iOS App Store apps.
