Final answer:
To properly ventilate a patient with a perfusing rhythm, the frequency of squeezing the bag depends on the respiratory rate and can be adjusted to maintain adequate alveolar ventilation and prevent carbon dioxide buildup.
Step-by-step explanation:
To properly ventilate a patient with a perfusing rhythm, the frequency of squeezing the bag depends on the respiratory rate of the patient. The average respiratory rate for a non-exerting individual is 12-15 breaths per minute. To maintain adequate alveolar ventilation and prevent carbon dioxide buildup, the respiratory rate can be increased while decreasing the tidal volume of air per breath or decreased while increasing the tidal volume per breath. Both methods maintain the same ventilation but require different work.
