System H&P Flashcards
What is the major respiratory issue that is seen?
Chronic cough
What are the major pulmonary ssx?
Dyspnea Cough Wheezing Chest pain Breathing disorders Sputum production
What is the definition of dypsnea?
Difficult, labored, uncomfortable breathing that is qualitative, and subjective
What is the major difference between pathologic and physiologic dyspnea?
Pathologic is uncomfortable since it occurs when you’re not exerting yourself
What causes dyspnea? (2). What modifies these?
Unknown but related to a high level of ventilation perceived centrally
Length tension dissociation of respiratory muscles
Modified by attention
How do you elicit information about how bad the dyspnea is? What is the progression of dyspnea (6)?
How much exertion:
- DOE
- walking
- Bathing/changing clothes
- Talking
- at rest
- changing positions
What are the two major characteristics of the history that should be asked with SOB?
Onset (rapid vs gradual) Activity level (progression)
What part of the brain is responsible for perceiving dyspnea?
Limbic system
What is the problem with beta blockers on the respiratory system?
Block beta 2 receptors, making asthma worse
What is the most useful indicator for the level of severity for SOB?
Activity level
Are rating scales to rate SOB used often clinically?
No, mostly for studies
What heart dysfunction may present with sudden DOE (besides MI)?
LV failure or PE
What are the three main causes of pneumothorax?
Idiopathic
Iatrogenic
Trauma
In whom is spontaneous pneumothorax common?
Tall, thin, smoking males
What are the physical ssx of hyperventilatio?
Cyanosis
Tingling in the lips
SOB over 1-2 hours = ?
LV failure
PE***
Dyspnea with hyperventilation = ?
Acidosis
Poisoning
Hyperventilation syndrome
True or false: tachypnea = hyperventilating
False, hyperventilation associated with decreased pCO2 on ABG
Immediate pain with SOB = ? (3)
Pneumothorax
FB aspiration
PE
True or false: recurrent PE is usually abrupt onset
False–usually gradual since they have many, smaller emboli
What is pneumoconiosis? Is this gradual or sudden onset?
Inhalation of inorganic particulates
Gradual onset
What is wheezing?
High pitched sound with inspiration or expiration
What is the cause of wheezing?
Airway obstruction
Inspiratory wheezing is suggestive of what? Why?
Upper airway obstruction, outside of the thoracic cavity
Lower airway tends to collapse with each breath
