Survival after out-of-hospital cardiac arrest (OOHCA) in an urban environment is directly proportional to speed of defibrillation and effective bystander cardiopulmonary resuscitation (CPR). We hypothesized that the hospital discharge rate from rural OOHCA was affected by the same factors. ⋯ Our data suggest improvement in response time and bystander CPR might further improve survival in a rural setting.

To measure an appropriately sized nasopharyngeal airway, it is taught that the size is related to the patients little finger or nostril (anterior nares). This study has been designed to identify whether these comparisons are valid. ⋯ The methods used traditionally to size a nasopharyngeal airway do not correlate with the airway anatomy and are unreliable. It is more appropriate to size the airway dependent upon the patient's size, sex and race.

To investigate the response to cardiac arrest in general wards. ⋯ The majority of the cardiac arrest teams have acceptable response times, but their efficiency may be impaired by the lack of staff, equipment and co-ordination with the ward personnel. CAT members identified a strong need for BLS training of ward personnel. More widespread introduction of standard protocols for resuscitation and reporting of cardiac arrest are necessary to evaluate aspects that may need improvement.

Carbon monoxide (CO) poisoning remains the leading cause of death by poisoning in the world. One of the major proposed mechanisms for CO toxicity is the binding of CO to cytochrome oxidase and interference with cellular oxygen utilization but evidence for this is inconclusive. ⋯ In this canine model of prolonged CO exposure, no gradual reduction in VO(2) or increase in systemic lactate prior to reaching DO(2)crit was noted. In addition, CO exposure does not appear to change the DO(2)crit. The combination of these findings does not support the theory that CO produces a whole body intracellular defect in oxygen utilization.

Non-traditional and lay first responders increasingly are being trained in the skill of defibrillation. With simplification of new devices, there is a need to determine optimal first responder selection and training and maintenance of this important skill. These issues are of prime importance for the St John Ambulance Australia Operations Branch which already has a substantial first response defibrillation programme. ⋯ For St John first responders proficient in cardiopulmonary resuscitation (CPR), the skill of defibrillation with an AED is readily acquired and maintained. While less experienced members may be less likely to acquire the skill initially, once acquired the skill is equally maintained by all, provided ongoing 'on duty' exposure is available.
