Pulmonary Patho Flashcards
Signs and Symptoms of Pulmonary Disease
Dyspnea, Orthopnea, PND, Abnormal breathing patterns, hyper/ hypoventilation, cough, abnormal sputum, cyanosis, clubbing,
Subjective sensation of uncomfortable labored breathing
Dyspnea (SOB)
Dyspnea when a person is lying down
Orthopnea
Paroxysmal nocturnal dyspnea (PND)
Dyspnea occurring at night when a person is lying down, generally w/ LV heart failure
Tachypnea
Breathing too fast
Bradypnea
Breathing too slow
Apnea
Stop breathing, fatal when sustained`
Kussmaul respirations
type of hyperventilation that is the lung’s emergency response to acidosis. Causes a labored, deeper breathing rate. It is most commonly associated with conditions that cause metabolic acidosis, particularly diabetes.
Notice fruity breath
Cheyne-Stokes respirations
Patient will take several breaths followed by a long pause before regular breathing resumes. These cycles of breathing will become increasingly deeper.
A near death breathing pattern.
Hemoptysis:
Blood in sputum
Hypoventilation:
What can this lead to?
Decreased amount of air being brought into the lungs, shallow breaths.
Hypercapnia: elevated CO2, leading to acidosis
Hyperventilation:
Too much breathing, deep breaths
Hypocapnia: decreased CO2, leading to alkalosis
Cyanosis:
Acute hypoxia, due to lack of O2. Blue coloration in finger tips, lips etc.
Clubbing:
Chronic hypoxia, long term chronic respiratory issues
Hypercapnia:
excessive CO2 in the bloodstream, typically caused by inadequate respiration. Decreased pH (respiratory acidosis)
Hypoxemia
What is an example of this?
an abnormally low concentration of oxygen in the blood. Ventilation-perfusion abnormalities
Eg: Shunting- sending blood flow elsewhere when one area does not have good gas exchange
Hypoxemia vs hypoxia
-ima = “in the blood”
in any tissue
What has occurred when the lungs have lost the ability to perform gas exchange
Acute respiratory failure
Excess water or fluid in the lungs
not a disease, but an outcome due to something else (trauma, inflammation etc.)
Pulmonary edema
what are the ways that pulmonary edema forms?
LV dysfunction
Blockage of lymph vessels
Increased capillary permeability
What is Aspiration?
What structure should stop this?
Where does this typically occur?
- Passage of fluid and solid particles into the lungs
- Epiglottis didn’t do its job
- Typically occurs in the Rt. lung (due straighter angle compared to Lft.)
Atelectasis:
alveoli collapse
Compression atelectasis
An external blockage compressing the airway
eg: tumor presses the airway that’s blocks it
Absorption atelectasis
the alveoli becomes closed off and all the air it contained is absorbed out and into the blood stream
Surfactant impairment
increase surface tension due to lack of surfactant leading to collapse
What can help the pore of Kohn open to allow another entrance into the alveoli
Deep breathing
Bronchiolitis
children
adults
Inflammatory obstruction of the small airways
- Most common in children (RSV)
- Occurs in adults with chronic bronchitis, in association with a viral infection, or with inhalation of toxic gases
