nick normal alveolar ventilation rate (AVR) during mild exercise is 6.0 L/min. She goes snorkeling to a beach, on a warm summer day, water is not too cold. The snorkel volume is 50 ml. Assuming this is a mild exercise for Angina, what should be her respiratory rate to maintain 6.0 L while snorkeling. (Assume a constant tidal volume of 500 ml and anatomic dead space of 150 ml)

    RR = 17.14min∧-1

    Explanation:

    AVR = 6L/min

    snorkel volume = 50ml

    to calculate the respiratory rate to maintain 6l/min (AVR)

    Tidal Volume = 500 ml

    anatomic dead space = 150ml

    Alvedar ventilation rate = (TV - Anatomic dead space) x RR

    6l/min = (500 - 150) ml x rr

    600ml = 350 x RR

    RR = 600ml/mins/350ml

    RR = 17.14min∧-1
