Where do upper airway infection begin and end? |
They start at the mouth nd finish ant the larynx, they also encompasses lymphoid tissues in the pharynx and eustachian tube that connect the pharynx and the middle ear. |
|
|
|
Name the Obstructive airway (lung disease) |
Asthma and COPD |
|
|
|
Hallmark of obstructive pulmonary disease, |
During inspiration bronchioles dilate, during expiration they constrict, with the increased mucus, inflammation and bronchospasm the air is trapped during exhalation |
|
|
|
What creates the diffusion problem of emphysema |
The destruction of alveolar walls decreases the surface area for gas exchange with cause the diffusion problem |
|
|
|
In emphysema what leads to cor pulmonae |
The destruction of alveoli = destruction of capillaries which increases resistance to the pulmonary blood flow = hypertension / right ventricular hypertrophy then right heart failure and death |
|
|
|
In emphysema why does the vital capacity remain the same while the residual capacity increase? |
Because you are able to inhale the same amount as usual only it most of the air you exhale will remain trapped, the trapped air is the cause of the barrel chest |
|
|
|
Partial pressure of alveoli VS partial pressure of arteries |
PA = partial pressure of alveoli Pa = partial pressure of arteries |
Alveoli come before arteries |
|
|
Partial pressure of alveoli VS partial pressure of arteries |
PA = partial pressure of alveoli Pa = partial pressure of arteries |
Alveoli come before arteries |
|
|
Name the S/S of emphysema and state the cause |
- Barrel chest due to air trapped, - Skinny appearance as they burn most of their caloric intake to respiration - pink skin color due to polycythemia - long smoking history - hypertrophy of the accessory respiratory muscles. - Pursed lips to create back pressure to keep alveoli open - we call them pink puffer - sign of right heart failure ( peripheral edema, JVD) |
|
|
|
In CB why is the vital capacity is decreased and the residual capacity remain normal or decrease |
Because the ventilation problem is caused by excessive mucus occupying the airways, so space that was previously filled with air is now filled with fluids |
