|
What is responsible for changing our rate of respiration?
|
CO2-->pH
|
|
|
what should O2 sat levels be at?
|
94% or greater
|
|
|
if the graphic representation of spirometry shows scooping or a dip in the slope, what does this mean
|
airway obstruction
|
|
|
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.
|
Fixed Obstruction
|
|
|
which part of breathing will be effected by variable extrathoracic problems
|
effects during INSPIRATION
|
|
|
|

|
|
|
what will be more effected in COPD, the FEV1 or FVC?
|
FEV1..have trouble getting air out
|
|
|
what will be more effected in restrictive airway problems, the FEV1 or FVC?
|
Reduced FVC, lower overall volume
|
|
|
obesity is similar to COPD or restrictive disease?
|
Similar to restriction due to abdominal weight /pressure causing early closure of airways
See low ERV and increased RV |
|
|
what are the 4 parts of pulmonary function testing
(summary slide that I didn't star earlier) |
Spirometry
flow volume loops lung volumes diffusion |
