How many lobes in the Lung
2
Is there gas exchange in the conducting airways?
No
Aspiration Pneumonia tend to occur more in which lung?
R
What are the gas exchange airways?
Resp bronchioles
Alveolar ducts
Alveoli
What line the bronchi and produce mucous?
Goblet cells
What does the apneustic center do
Prevents over inflation of the lungs
What does the pneumotaxic center do
Limits amount of inspired air
The ability of the lungs to expand and return to resting volume at expiration is due to
The elastic properties of the lung and the chest wall
Compliance is the ability
Of the lung and chest wall to stretch
A loss of elastic recoil will increase the _______
Compliance
Makes it abnormally easy to inflate but difficult to return
A decrease in compliance will cause
The lungs to be very still and difficult to inflate
Compliance is in disorders such as
Emphysema
Compliance is decreased in orders such as
Pneumonia
Cystic fibrosis
In pulmonary edema there is _____lung compliance which ____ muscular effort thus ____ work of breathing
Decreased
Increases
Increases
Haldane effect
Effect of o2 on co2 transport out of blood
Acidemia causes pulmonary ______
Constriction
Most important things to look at with spirometry
Forced vital capacity- how much a person can expire out after normal expiration
Forced expiratory volume in one second
Diffusion capacity
Measure of rate of gas diffusion at the alveolarcapillary membrane
Decreased diffusion capacity is seen is diseased such as
Emphysema
ABGs show what
Useful to determine pH, oxygen and carbon dioxide levels in arterial blood
Tells us about gas exchange and acid base status
What can only be determined with ABG
Acidosis
Alkalosis
Ventilatory alterations
Decreased partial pressures of oxygen
How does aging affect the mechanical aspects of ventilation
Decreased chest wall compliance
Decreased elastic recoil of lungs
Alterations in gas exchange
Increases flow resistance
Aging causes the ______ to decrease but does not affect the _______
PaO2
PaCO2
