BS 6850:2002 pdf free.Gas powered ventilatory resuscitators.
BS 6850 1 Scope This British Standard specifies performance and safety requirements for gas powered ventilatory resuscitators (hereinafter referred to as resuscitators) intended for use with patients of any body mass.Requirements are also included for equipment essential for the use of a resuscitator as a self-contained piece of portable equipment, e.g. a gas supply system and carrying case. It applies to resuscitators intended for use by paramedical and medical personnel and also for emergency use by personnel with very limited training. They may be used at the scene of emergencies both inside and outside hospitals or during patient transport.
No requirements are included for face masks although recommendations for these are given in Annex A.Operator-powered resuscitators, electrically-powered resuscitators, automatic pressure-cycled gas-powered resuscitators, devices which have been designed only to deliver gases to a patient breathing adequately, or devices which are designed to assist or provide for the ventilation of a patient for an extended period of time are outside the scope of this standard.
The effective and safe use of a ventilatory resuscitator is determined not only by the performance of the resuscitator, but also by the skill of the operator. This standard does not describe the content of the training programmes to develop such skill and does not state who should or should not use a resuscitator; this will be determined by the organizations involved in teaching resuscitation.
Ventilatory resuscitators complying with the requirements of this standard are suitable for use with closed-chest cardiac compression. Currently available automatic pressure-cycled gas-powered resuscitators are not considered suitable for such use because the increa sed intrathoracic pressure occurring during chest compression causes the resuscitator to cycle from the inspiratory mode to the expiratory mode prior to adequate ventilation of the lungs. These resuscitators have therefore been excluded from the scope of this standard. Ventilatory resuscitators are used in widely varying environments and additional requirements may be necessary in certain situations, e.g. in mine rescue work, where a flammable or toxic atmosphere may be present, or where a dusty environment may occur.BS 6850 pdf download.
