Ventilation in Humans

Question 1

What is used to represent ventilation or breathing rates?

Answer 1

a spirometer trace

Question 2

What is the tidal volume?

Answer 2

volume of air breathed in or out per breath at rest

Question 3

What is the breathing / ventilation rate?

Answer 3

number of breaths per minute

Question 4

What is the formula to calculate the total volume of air breathed in one minute?

Answer 4

tidal volume x breathing rate

Question 5

What is oxygen consumption?

Answer 5

volume of oxygen used per minute

Question 6

What is the effect of exercise in tidal volume, breathing rate, and rate of oxygen consumption?

Answer 6

tidal volume - increase (deeper breaths)
breathing rate - increase (faster breaths)

rate of oxygen consumption - increases more respiration
