ROX Index vs F&P ROX Calculator Usage & Stats
The application is designed for doctors and medical students that helps to calculate ROX. ROX is an index that is formulated to predict the chance of success or failure of HFNC. It has been studied mostly in patients with Pneumonia. It is calculated as –
Oxygen saturation (SpO2) / Fraction of Inspired Oxygen (FiO2) X Respiratory rate (RR)
(Range for SpO2 : 70% – 100%,
Range for FiO2 : 21% – 100%,
Range for RR : 12/min – 70/min)
As is obvious, the higher the index, the better is the chance of success.

The ROX index combines respiratory rate and oxygenation to help predict outcomes of Nasal High Flow Therapy together with normal clinical judgement.
F&P ROX Calculator is a simple tool that allows you to calculate a patient's ROX index. The ROX index for a patient is calculated by dividing the SpO2 / FiO2 ration by respiratory rate, thus is easily measured and repeated at the bedside. The index can be used together with clinical judgement to assess whether mechanical ventilation may or may not be a required after initiation of NHF therapy. The index has been validated for patients with Acute Hypoxemic Respiratory Failure due to pneumonia (a link to this study in included from within the app).
The ROX index should never replace normal clinical judgement.
