pulmonary Flashcards
pulmonary embolism
cough, frothy pink tinged sputum. “IMPENDING DOOM”
impending respiratory failure (asthma pt)
RR >25bpm, tachy, cyanosis, “quiet” lungs no wheezing.
Adrenaline injected STAT, call 911. 02 4-5L, albuterol.
after tx, good sign is breath sounds and wheezing.
normal findings of lungs
upper lobes: bronchial breath sounds (louder)
lower lobes: vesicular (soft and low)
normal egophonys
normal: “eee”
abnormal “bah”
normal “eee is louder over the large bronchi” vs lower lobe
tactile fremitus
normal: stronger vibrations on the upper lobes
whispered pectoriloquy
patient to whisper “99 or 1-2-3”
normal: voice lounder upper lobes, muffled lower lobes
abnormal: clear sounds lower, muffled upper
percussion
normal: resonance
tympany or hyperresonace: COPDY, emphsema
dull: pneumonia with consolidation, pleural effusion (liquid or tumor), solid organ (liver)
pulmomary fxn tests
obstructive dysfuncion - reduction in airflow
asthma, copd
restrictive- reduction of lung volume dt decreased lung compliance
ie; pulmonary fibrosis, pleural disease
COPD
includes both emphysema and chronic bronchitis
loss of elastic recoil of the lungs and alveolar damage
risk: smoking and age
chronic bronchitis
cough with excessive mucus 3 months or more
for a minimum of 2 or more consecutive years
emphysema
permanent alveolar damage
expiratory respiratory phase is longer
risk: smoking, age, occupation, alpha 1 trypsin deficiency
classic case: elderly male, smoker, c/o sob during exertion. frequent cough, yellow sputum, barrel chest, weight loss (emphysema).
objective: >AP diameter,
copd general tx
smoking cession
flu, penumococcal vaccine
pulmonary drainage
copd medications
1st line: anticholinergics Ipatropium (atrovent) or tiotropium (spiriva)
and/or
b2 agonist: salmetrol (serevent), formoteral, albuterol (combivent)
2nd line: prednisoe (medrol dose pack), fluticason, adviar
copd medications safety
albuterol (b2 agonist)- careful with htn, hyperthyroid
anticholingergics (atrovent, spiriva), avoid if narrow angle glaucoma, bhp, bladder neck obstruction dt vasoconstriction
long term use of corticosteroids >6mos= risk of pneumonia
when treating COPID, pick antibiotic doxy or fluoro (agains H. influenza gram -
true
CAP
bacterial infection s. pneumoniae h.influenze m. catarrhalis cystic firbosis
classic case: elder with high fever, productive cough, rust colored sputum, pleuritic chest pain
objective: rhonchi, wheeze, crackles, dullness on percussion
INCREASE tactile fremitius and egophany
xray is gold standard for diagnosing CAP ( NOT sputum), repeat 6 wks after clearing
cxr lobar consolidation
tx of CAP
Macrolide or doxy (tetracycline)
with comorbidity (kidney, chf, liver) fluroquinolonie as ONE drug therapy (leva, gemi, maxi)
or
high dose amoxi (augmentin) plus macrolide
curb 65
confusion, urea in blood, rr>30bpm, blood pressure
prevention of pneumonia
flu for everyone >50 yo
pneumovax if >65 yo
healthy patients - one lifetime dose at 65 yo
prevent of pneumonia for high risk patients
pneumovax booster in 5-7 years
19 yo if asplenia
atypical pneumonia
children/young adults
“walking pneumonia” highly contagious
M. Penumoniae
C. Penumoniae
Legionella pneumoniae- found in moisture (water, air conditioners)
classic case; youg adult several weeks fatigue, coughing non productive, cold like s/s.
wheezing, pus in throat, diffuse interstitial infiltrates on X-ray.
medications: macrolide (same as 1st line CAP), anitussive prn (dextromethorphan, tessalon perles)
acute bronchitis
aka treacheobronchitis, usually viral and self limiting
tx: fluids, antitusstives (dextromethorphan, tessalon perles, f
guaifensin prn, albuterol, if severe medrol dose pack
pertussis
bacterial
whopping cough
last 2 weeks or longer, “hacking cough”, may vomit.
labs: nasopharyngeal swab (PCR), ELISA, cbc
tx: marcolides
TDAP booster
typical vs atypical pneumonia
typical: (CAP) older pt. high fever (>100.4), productive cough, rust colored sputum, chest pain
* S. pneumoniae, H. inlfluenzae, M. catarrhalis
atypical: children/young adults. fatigue, nonproductive cough, low grade fever (cold like s/s)
* *M. pneumonia, C. pneumoniae, Legionella penumonaie
