Fisio Tools by AlecrimTech is a free Android app that assists respiratory physiotherapists in their day-to-day calculations. The app offers a comprehensive list of tools that are commonly used in respiratory physiotherapy, such as PaO2 ideal, FiO2 ideal, and Gradiente Alvéolo-Arterial de O2. Additionally, the app also includes tools like Gasometria, Ânion Gap, and Escala Hacor, amongst others.

One of the most convenient features of Fisio Tools is its ability to send calculation results via email, enabling easy communication between team members and the monitoring of patient progress. The app is designed for use with adult patients only and includes explanations about the formulas used in all its functions. However, it is not recommended for use with pediatric patients.

The only downside to the app is that it contains ads, but these can be removed by upgrading to the paid version. Overall, Fisio Tools is an efficient and practical app that can save time and aid in the treatment of respiratory patients.
