The resuscitators are made of PVC and for this reason they can be stored in a compressed form and return to their normal shape as soon as needed for use. The unequalled moulding technique allows calibrated thickness of the bag, improving the grip for the operator and the performance during expansion. Particular care was taken to the external surface finish of the Co B-life bag, which consequently has a colouring that, guarantees high visibility in conditions of low light. The resuscitator can supply the patient with air from the atmosphere (21% oxygen) and if connected to an oxygen enrichment system and the reservoir bag, it is able to supply a concentration up to 97%. The cost makes them ideal to equip a whole fleet of ambulances, doctors or dentist surgeries, first aid groups, industrial environments or a hospital ward, or where it is necessary to have resuscitation instruments on hand. Pro Blife and Co B-life can be sterilised in antibactericidal solutions. The low cost allows the resuscitators to be used as disposable products in particular situations where risk of infection is high.
