Flashcards in Resp Deck (19):
Chronic COPD ABG
pCO2 >40 (hypercapnea)
pO2 24 as this is chronic
IgM Abs that agglutinate RBCs at 4C (39.2 F)
Seen with Mycoplasma pneumoniae (extracellular bacteria)
Tx. Atypical CAP d/t Mycoplasma pneumoniae
Rocuronium and Sevoflurane can cause what adverse effect?
S&S of Theophylline toxicity
HypOtension, lethargy, confusion, A. Fib, seizures
Formerly used to reverse bronchospasm in asthma/COPD by inhibiting phosphodiesterase and releasing epinephrine from adrenal medulla
S&S of Massive Pulmonary Embolism (PE)
- Acute RV failure --> neck vein distension (as blood backs up because RV can't push it to lungs) --> ↑ CVP
- ↑ Pulm. A. Pressure (d/t hypoxic vasoconstriction)
- Normal PCWP, SVR
- ↓ Cardiac Index (SV * HR / BSA)
- Right Bundle Branch Block
Mycobacterium tuberculosis category
Emphysema: purse lips, no cough, decreased breath sounds
Chronic bronchitis: cyanosis, cough, right-sided heart failure (Elevated end-diastolic right ventricular pressure: Systemic congestion - enlarged liver, ascites, jugular venous distention, dependent pitting edema; fatigue, liguria, nocturia, cyanosis, pleural effusion, anorexia and bleeding, unexplained weight gain)
Tx. for nosocomial pneumonia d/t pseudomonas
Piperacillin + Amikacin
Succinylcholine (depolarizing NM blocking drug)
ACh receptor agonist causing sustained depolarization thus preventing mm. contraction
hypercalcemia, hyperkalmia, malignant hyperthermia
Pancuronium (non-depol NM blocking drug)
Reverse blockade with?
competitive antagonist of ACh
Reversal of blockade: Neostigmine, Edrophonium, Cholinesterase Inhibitors
Heparin + Warfarin simultaneously for 5 days, until INR 2.0-3.0 then Warfarin only
Legionnaire's Disease keywords
Mental status changes
Findings seen in Bronchiectasis?
Increased bronchovascular markings
If a pt. has complicated pneumonia with no resolution even after ABX, get what diagnostic procedure done?
- can identify lung masses and collection of cultures
Dx: Bronchoalveolar lavage
Empiric ABX for Community Acquired Pneumonia?
Doxycycline for those younger than 60 y.o.
For 60+ y.o.: 3rd gen cephalosporins, Augmentin, Macrolides, and fluoroquinolones
