→‎INTRODUCTION

Sometimes, 21% of oxygen may not be enough to maintain adequate oxygen saturations. In these situations, supplemental oxygen can be administered via various oxygen delivery devices. It may be important to increase the "fraction of inspired oxygen" (FiO2). Introducing oxygen into a respiratory ventilation circuit allows the concentration of oxygen to be increased, potentially increasing the FiO2 to 100%. In non-invasive CPAP and BiPAP applications the delivered oxygen is much lower due to dilution from the CPAP venting rate that exceeds respiratory requirements.

With This article will show how to calculate the final oxygen concentration in a canula deliveryCPAP/BPAP circuit at the mask, and the approximate correlation between oxygen effect of PAP pressure on flow rate for any rate and FiO2, is similar concentration of oxygen added to the table below:circuit.
