BS EN 13544 is a European that discusses respiratory therapy equipment. BS EN 13544-3 is the third part of a multi-part series that outlines minimum performance and safety requirements for air entrainment devices used for delivery of a designated oxygen concentration to patients to ensure the practical degree of safety is achieved in the operation of air entrainment devices.
BS EN 13544-3 layouts a test method to check the oxygen concentration in the air/oxygen mixture generated by the air entrainment device.
BS EN 13544-3 also outlines the marking requirements and gives an optional system of colour coding to assist the user to identify the designated oxygen concentration.
Note: BS EN 13544-3 does not cover air entrainment devices that are integrated with medical devices specified in other standards e.g., emergency lung ventilators, humidifiers, nebulizers, etc.
BS EN 13544-3 on the air entrainment devices used for respiratory therapy is useful for:
An air entrainment device consists of a jet orifice (to which the oxygen supply is connected) adjacent to a series of air entrainment ports, the distal end of the device being designed for connection to an oxygen delivery system supplying a patient.
BS EN 13544-3 guideline assists you with oxygen supply, oxygen supply inlet, air inlet attachments, delivered oxygen concentration, marking, identification, colour coding, the information supplied by the manufacturer, usability, and clinical evaluation.
This assists in manufacturing efficient air entrainment devices and also guides in enhancing the durability and stability of these devices.
With obedience and compliance to BS EN 13544-3, you can standardise the performance and quality of air entrainment devices for safe use of these devices for respiratory therapy. In addition, minimise hazards to patients and the operators of air entrainment devices.
