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

a researcher conducts an experiment on the secretion of a particular hormone in mice. scientists inject mice with a substance that stimulates the production of the hormone. the scientists then test the levels of hormones produced by the mice. the tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. this tool makes measurements, but the measurements aren't .

no u
