Abstract:
BACKGROUND: AMBU bag is a useful equipment in the cardiopulmonary resuscitation(CPR) and respiratory therapy. The volume delivered during ventilation with AMBU bag may be influenced by many factors. METHOD: We evaluated the effects of ventilation method(one-hand, open-palm, two-hand) and resuscitator's sex on volume in 30 intubated patients under general anesthesia with inhalational anesthetics and muscle relaxants. RESULTS: Mean tidal volume was significantly greater with two-hand method than one-hand and open-palm method in both sex. PaO2 was significantly decreased in all ventilation methods. PaCO2 was also decreased and pH was increased in all methods. CONCLUSION: The results suggest that all ventilation methods with AMBU bag in intubated patients may suitable in the CPR. If airway management by intubation is impossible and mask ventilation, two-hand method may be effective in both resuscitator but open-palm method may not suitable to female resuscitator.
