Hypertension and COPD Flashcards
Describe normal and abnormal breath sounds, such as crackes and wheezes.
- normal breath sounds: tracheobronchial (trachea), bronchovesicular (carina, mainstem) and vesicular (all lung fields)
- crackles (fine- inspiration vs coarse-expiration), discontinuous sounds, rice krispies or dry leaves
- wheezes (low pitched vs high pitched), continuous sounds, more commonly heard on expiration but can be both, snoring or high pitched whistle
With COPD, dysfunctional cilia make clearing secretions difficult if not impossible. What generation is it necessary to clear secretions to make respiration easier?
The 6th generation.
What do MIP and MEP measure?
Maximum ventilatory muscle strength.
What 3 measures are important in telling if there is a gas exchange problem?
1) SpO2
2) PaO2
3) PaCO2
With a cardiovascular pump dysfunction, there usually abnormal vital signs and/or changes such as a flat response to activity. People can also experience decreases in HR and BP with increased workload. What are other lab measure that can identify dysfunction?
EF normal
>1-2 mm ST elevations or depressions
Angina
Onset of ventricular extopy with > workload (>7 PVCs per minute)
24-48 hours of bedrest can lead to deconditioning, though the normal person wouldn’t notice because they have enough functional reserve. What other sign signal deconditioning?
Exaggerated vitals: > than expected increase in HR, BP, RR, RPE, DOE with workload.
What are the signs of peripheral ischemia?
Claudication with ambulation
ABI < 0.5
Describe four pathological types of ventilation: adeventitious sounds, purse lip breathing, collateral ventilation and effect, non-productive coughing.
ADVENTITIOUS SOUNDS
-added sounds not natural to the lung
-crackles, pleural friction, etc.
PURSE LIP BREATHING
-in through the nose, out through the mouth
-increased expiratory pressure allowing more time for gas exchange to occur
COLLATERAL VENTILATION
-When neighboring alveoli help facilitate gas exchange
-happens when there is an obstruction
EFFECTIVE, NON-PRODUCTIVE COUGH
-no airway clearance problem
-he can get things out, but there is nothing there
On a resting EKG, what are ST depression indicative of?
Ischemia and angina.
What is %MVV? What is RER?
%MVV
-maximal voluntary ventilation
-max in and out breath test
RER
-respirator exchange ratio
-CO2/O2, <1 at rest, diet dependent (0.8)
-increases to about 1 with activity due to increased CO2 production
-1.2-1.5 is max exercise test
What are the most important impairments in a patient with emphysema, and what are you going to treat (based on patient in deck)?
IMPAIRMENTS
-Endurance (decreased VO2)
-Posture (from exam)
-Ventilatory pump (increased A/P diameter)
-Decreased muscle strength
-Gas exchange problem (decreased SpO2)
-CV pump problem (ST depression)
TOP IMPAIRMENTS TO TREAT
-muscular strength (most economical change), benefitting:
-CV Pump
-Vent Pump
-Gas exchange
