Respiratory System 2 Flashcards
(15 cards)
what is tidal volume
the amount of air you breathe in or out during one breath
what happens to your tidal volume during exercise
it increases as you take deeper breaths
what is the inspiratory reserve volume
the extra air you breathe in after a normal breath in
what is the expiratory reserve volume
the extra air you breathe out after a normal breath out
what is residual volume
the air left in your lungs after you breathe out as much air as you can
what do big changes in volume on a spirometer trace show
maximum inspiration and maximum expiration
what do small changes in volume on a spirometer trace show
normal breaths in and out
what is the tidal volume on a spriometer trace
the difference in volume between a peak and a dip, around 500ml at rest
what is the inspiratory reserve volume on a spirometer trace
the difference between a maximum breath in and a normal breath in, around 3 litres at rest
what is the expiratory reserve volume on a spirometer trace
the difference between a maxiumum breath out and a normal breath out, around 1.2 litres at rest
what is the residual volume on a spirometer trace
the difference between a maximum breath out and the minimum lung volume, around 1.2 litres at rest and when exercising
what happens during the exercise part of a spirometer trace
the peaks are higher and the dips are lower than during the rest part
what happens to your breathing rate during exercise
it increases as you take more breaths per minute than when you’re resting
how is breathing rate shown on a spirometer trace
the peaks are closer together during exercise
how does exercising affect inspiratory and expiratory reserve volumes
you breathe more in and out more air than normal so you can’t breathe in and out as much extra air which leads to reserve volumes decreasing
