[The ROX Index] Is there a bedside tool that provides an indicator of nasal high flow outcomes?

ROX Index explained and educational tools
The ROX*index* combines three common measurements: FiO2, SpO2, and respiratory rate, and is based on two well-known facts: 1. Sicker patients require more oxygen, and 2. Have a higher respiratory rate. The index has been validated in a multi-center prospective study on 191 patients with pneumonia.*
