Final Answer:
While CPR is being administered and an advanced airway has been placed, ventilations should be given regularly 1 breath every 10 seconds. Thus, the correct answer is b) 10.
Step-by-step explanation:
In CPR with an advanced airway, the recommended ventilation rate is 1 breath every 6 seconds. However, during the administration of CPR, the chest compressions should continue uninterrupted. When an advanced airway, such as an endotracheal tube or supraglottic airway, is in place, the chest compressions can be delivered continuously at a rate of 100 to 120 compressions per minute, which equals around 1 compression every 0.5 to 0.6 seconds.
For effective ventilation during CPR with an advanced airway, it is crucial to synchronize ventilations with the ongoing chest compressions. Typically, the recommended ratio is 30 compressions to 2 ventilations in standard CPR protocols without an advanced airway. However, when an advanced airway is present, the emphasis is on continuous chest compressions with asynchronous ventilations delivered at a rate of 1 breath every 6 seconds (or 10 breaths per minute).
Calculating this, one breath every 6 seconds translates to 10 breaths per minute (60 seconds ÷ 6 seconds = 10 breaths). Therefore, in the scenario described, while CPR is being administered with an advanced airway in place, the appropriate ventilation rate is 1 breath every 10 seconds, aligning with the updated guidelines for advanced airway management during CPR.
Thus, the correct answer is b) 10.
