<p>This document specifies minimum performance and safety requirements for <em>air entrainment devices</em> used for delivery of designated oxygen concentrations to patients. It provides a test method to check the accuracy of the oxygen concentration in the air/oxygen mixture generated by the <em>air entrainment devices</em>. <em>Air entrainment devices</em> can be fixed to deliver a single oxygen concentration or adjustable, to deliver a range of oxygen concentration outputs.</p>
<p>This document also specifies marking requirements and recommends an optional system of colour coding to assist the user in identifying the designated oxygen concentration.</p>
<p>This document does not cover <em>air entrainment devices</em> which are integral with medical devices specified in other standards (e.g. emergency lung ventilators, humidifiers, nebulizers).</p>
