37
Q

define dead space?

A

the portion of each tidal volume that doesn’t take part in gas exchange

38
Q

define dynamic lung volume?

A

lung volume dependent on the flow rate at which air can be exhaled

39
Q

define vital capasity?

A

the maximal volume expelled after maximal inspiration

40
Q

define inspiratory reserve volume?

A
  • the amount of air that can be forcibly inspired after a normal inspiration.
41
Q

define expiratory reserve volume?

A
  • the amount of air that can be forcibly expired after a normal expiration.
42
Q
A

the maximal volume expired from resting inspiratory level.

43
Q
A

the amount of air exhaled or inhaled during a respiratory cycle.

44
Q

define residual volume?

A
  • the amount of air remaining in lung after maximal expiration. (RV=VCx0.25)
45
Q

define inspiratory capacity?

A
  • the maximal volume inspired from resting expiratory level (IC=VT+IRV)
46
Q

define functional residual capacity?

A
  • the air volume that remain in the lung at resting expiratory level. (FRC=ERV+RV)
47
Q

define total lung capacity?

A
  • the air volume in the lungs at the end of maximal inspiration. (TLC=VC+RV)
48
Q

define minimal volume?

A
  • achieved when lung collaps. Fraction get into interstices by diffusion at first breath
49

54
Q

What happens with the heart rate during inspiration? Explain

A
  • During inspiration the heart rate is higher than during expiration.
55
Q

What is meant by respiratory sinus arrhythmia (RSA)?

A
  • changes is heart rate in connection with respiration
56
