Final answer:
One ventilation every 6 seconds is the correct frequency when delivering ventilations to an adult in respiratory arrest, which aligns with the advised 10 breaths per minute for adult patients in this situation.
Step-by-step explanation:
To assist an adult patient experiencing respiratory arrest, the correct frequency for delivering ventilations is approximately one ventilation every 5 to 6 seconds. The respiratory rate for a healthy adult under non-exertion conditions is typically between 12-15 breaths per minute. Therefore, providing 1 ventilation every 6 seconds equates to 10 breaths per minute, which is slightly lower than the normal respiratory rate but allows for adequate ventilation during a rescue situation.
During a rescue scenario, it's essential to maintain proper alveolar ventilation to prevent carbon dioxide buildup in the alveoli. It is equally critical to ensure that enough oxygen is delivered to the patient's organs and tissues. The goal is to mirror the normal respiratory rate of an adult, which lies within the range of 12 to 18 breaths per minute, while keeping in mind the urgency and controlled circumstances of providing rescue breaths.
Furthermore, it's important for medical personnel to continuously assess the patient's condition and the effectiveness of the ventilations, and adjust as necessary within recommended guidelines. Immediate medical assistance may be required if the patient does not respond to the ventilations.
