CSA Z168.5.6:96 (R2021)

Preface This is the first edition of CSA Standard CAN/CSA-Z168.5.6, Expired-Air Pulmonary Resuscitators . It was developed to provide standard testing protocols and criteria that manufacturers can use as a basic reference guide to design and development, and buyers can use for comparison of devices. This Standard was prepared by the Working Group on Expired-Air Pulmonary Resuscitators under the jurisdiction of the Technical Committee on Anaesthetic Equipment and Respiratory Technology and the Standards Steering Committee on Health Care Technology, and has been formally approved by these Committees. This Standard has been approved as a National Standard of Canada by the Standards Council of Canada. Scope 1.1 This Standard includes all devices designed to assist in the provision of expired-air pulmonary resuscitation. These devices are designed to aid in the protection of the rescuer from communicable diseases transmitted from the area covered by the device via bodily fluids and/or expired air. This Standard includes but is not limited to one-way valve/filter devices incorporating either a face mask, face shield, or oropharyngeal airway. 1.2 This Standard does not include devices designed for oesophageal intubation because of the severity of the complications which may attend their use. In addition, laryngeal masks and combined pharyngeal-tracheal airways are not included because studies that evaluate their efficacy for expired-air resuscitation in emergency settings have not yet been concluded.
