Front 1

What is responsible for changing our rate of respiration?

Back 1

CO2-->pH

Front 2

what should O2 sat levels be at?

Back 2

94% or greater

Front 3

if the graphic representation of spirometry shows scooping or a dip in the slope, what does this mean

Back 3

airway obstruction

Front 4

Firm tracheal lesions may limit the modulating effect of transmural pressures on airway luminal diameter. In this pattern, flow is limited during both inspiration and expiration, with flattening of both limbs of the flow-volume loop.

Back 4

Fixed Obstruction

Front 5

which part of breathing will be effected by variable extrathoracic problems

Back 5

effects during INSPIRATION

Front 6

what will be more effected in COPD, the FEV1 or FVC?

Back 6

FEV1..have trouble getting air out

Front 7

what will be more effected in restrictive airway problems, the FEV1 or FVC?

Back 7

Reduced FVC, lower overall volume

Front 8

obesity is similar to COPD or restrictive disease?

Back 8

Similar to restriction due to abdominal weight /pressure causing early closure of airways

See low ERV and increased RV

Front 9

what are the 4 parts of pulmonary function testing

(summary slide that I didn't star earlier)

Back 9

Spirometry

flow volume loops

lung volumes

diffusion

Front 10

Spirometry determines the presence or absence of ______________

Back 10

Airway Obstruction

Front 11

The flow volume loop is a _______ representation of spirometry

Back 11

The flow volume loop is a GRAPHICAL representation of spirometry

Front 12

Demonstrates flattening/plateau of the maximal expiratory curve, resulting from expiratory flow limitation

Back 12

Variable Intrathoracic

Front 13

Variable Intrathoracic

flow limitation is encountered during forced expiration, when the pleural pressure becomes positive
relative to airway pressure, and the effect of any obstructive lesion in this region is ______

Back 13

accentuated

Front 14

This Lung Volume Test measures both ventilated and unventilated areas of the lungs – good for COPD

Back 14

Plethesmography

Good for COPD vs. Restriction eval

Front 15

We need oxygen for ____ production

Back 15

ATP

Front 16

Chemo and baroreceptors drive respiration by monitoring ______

Back 16

CO2--->pH

Front 17

Inspiration is a/an ______ process.

Back 17

active

Front 18

Expiration is a/an ______ process

Back 18

passive

Front 19

Spirometry alone cannot diagnose ______

Back 19

Restrictive lung diseases

Front 20

Flow Volume Loops

Back 20

Fixed Obstruction = flattened insp. & exp

Variable Extrathoracic= flattened insp.

Variable Intrathoracic= flattened exp.
