Final answer:
Ventilation rate for PPV is typically (b) 40-60 breaths/min to ensure effective oxygenation without causing complications.
Step-by-step explanation:
When administering positive pressure ventilation (PPV), the correct ventilation rate typically falls within the range of 40 to 60 breaths per minute. This range ensures adequate oxygenation without causing excessive ventilation-related complications. Too rapid ventilation might lead to decreased venous return, compromising cardiac output, while slower rates might not maintain proper oxygenation.
The optimal rate can vary based on the patient's age, condition, and underlying factors. For adults, a rate of around 10-12 breaths per minute could be sufficient during rescue breathing. However, in scenarios like cardiac arrest, higher rates (100-120 breaths/min) might be used initially. It's vital to consider individual patient needs and response while providing PPV to maintain adequate oxygenation and ventilation without causing harm.
