How should high concentration oxygen be provided with a resuscitator during resuscitation

: Oxygen is essential to life. When one is suffering from illness or trauma, the oxygen demand increases because of catabolic response. High concentration oxygen is therefore required in resuscitation. In Taiwan, as well as in other countries, medical personnel usually provide artificial ventilation with a resuscitator. However, the percentage of oxygen delivered from the bag varies significantly in different conditions. To provide high-concentration oxygen during resuscitation, it is necessary to use a resuscitator with an oxygen reservoir and sufficient supplemental oxygen flow.
