13
Q

what occurs to resistance and flow in dynamic compression?

A

flow is limited and resistance is increased as interpleural pressure increases

= results in effort independence of the flow-volume loop

16
Q

emphysema and COPD are characterized by _____lung compliance and _____elasticity

A

high and low
also sucky recoil.. alveoli pressure was supposed to be +10 but it is +2
the airway pressure found here is lower than its supposed (32 instead of 40 at strong expiration) to be and inter pleural pressure is 30.

17
Q

In what direction does the flow volume loop shift if there is obstruction?

A

left

18
Q

In was direction does restriction shift the flow volume loop?

A

shifts it right

19
Q

there is _______ airway resistance and _______ airway generation as you go down a lung from segmental bronchi to terminal bronchioles

A

decreased and more

20
Q

As volume ______ resistance _______

A

increases, decreases

21
Q

at terminal bronchioles airflow is _______. at the trachea airflow is _______.
Transitional flow_____.
In laminar conditions airflow is proportional to ______
in turbulent flow airflow is proportional to _______.

A

laminar, turbulent, both, change in pressure, square root of change in pressure

this is from
flow= change in pressure / resistance

22
Q

How does CO go through pulmonary circulation?

A

in series

23
Q

what is the mean pressure of pulmonary artery in pulmonary circulation?
left atrium?
driving pressure?

A

15 mmHg
8 mmHg

15-8=7

24
Q

what is the difference between a pulmonary capillary bed and systemic capillary network in terms of resistance and area?

A

pulmonary capillary bed has larger cross sectional area which means less resistance.

on the contrary in systemic circulation the capillary network has smaller cross sectional area so more resistance

25
Q 
In alveolar vessels Increased lung volume during end max inspiration has
\_\_\_\_ air pressure on BV
\_\_\_\_ radius, alveolar vessels compressed
\_\_\_\_ resistance
\_\_\_\_ flow
A

increased
decreased
increased

they depend on air pressure directly

26
Q 
In Extra alveolar vessels Increased lung volume end max inspiration has
Pleural pressure \_\_\_\_ negative
\_\_\_\_ radius 
\_\_\_\_ resistance
\_\_\_\_ flow
A

more
increased
decreased
increased

depend on intrapleural space pressure

27
Q 
In alveolar vessels decreased lung volume end max expiration has
\_\_\_\_ air pressure on BV
\_\_\_\_ radius, alveolar vessels open
\_\_\_\_ resistance
\_\_\_\_ flow
A

decreased
increased

28
Q 
In Extra alveolar vessels decreased lung volume end max expiration has
pleural pressure \_\_\_\_\_\_ negative
\_\_\_\_ radius 
\_\_\_\_ resistance
\_\_\_\_ flow
A

less
decreased
more
decreased

29
Q

how do you increase pulmonary vascular resistance?

A

increasing arterial pressures from low levels
recruitment= using already available cross sectional area, some capillary networks have no blood flow in the lungs this increases cardiac output
Distention= vasodilation can open new cross sectional area to further augment total cross sectional area
