Answer :
Final answer:
If a choking victim is unresponsive, perform cardiopulmonary resuscitation (CPR) before giving breaths. Emphasize chest compressions, then artificial respiration. Proper position, depth, and frequency are essential.
Explanation:
If a choking victim becomes unresponsive, the additional step before giving breaths is to perform cardiopulmonary resuscitation (CPR). Primarily, high-quality chest compressions should be prioritized over providing artificial respiration.
CPR maintains the flow of blood when the heart stops beating. By applying pressure to the sternum, blood is pushed from the heart into circulation, which is crucial for the brain as the loss of blood flow may lead to irreversible damage and death of neurons.
Proper positioning of hands on the sternum for performing CPR is between the line at T4 and T9 vertebrae. Modern standards suggest compressing the chest at least 5 cm deep and at a frequency of 100 compressions per minute, equivalent to the beat of 'Staying Alive' by the Bee Gees.
