ACS
This lab is the most specific for myocardial injury.
What is troponin?
This is the recommended compression-to-ventilation ratio for an adult in cardiac arrest without an advanced airway.
What is 30:2?
This biomarker is commonly elevated in acute decompensated heart failure and helps differentiate cardiac from pulmonary causes of dyspnea.
What is BNP or NT-proBNP?
The target oxygen saturation range for COPD patients with chronic hypercapnia.
What is 88–92%?
What are the three typical organisms commonly causing CAP?
Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis
The first-line single antiplatelet given to all ACS patients unless contraindicated.
What is aspirin?
This reversible cause of cardiac arrest is corrected by relieving tension in the chest cavity.
What is tension pneumothorax?
This NYHA class describes symptoms with ordinary activity but comfortable at rest.
What is Class II?
This single-inhaler type is the cornerstone of acute COPD exacerbation management.
What is a short-acting bronchodilator?
What are the three atypical organisms commonly causing CAP?
Mycoplasma pneumoniae, Chlamydophila pneumoniae, and Legionella pneumophila
This drug class reduces mortality in STEMI by decreasing myocardial oxygen demand and arrhythmias.
What are beta blockers?
This is the first drug administered during pulseless VT/VF after CPR and defibrillation.
What is epinephrine?
In acute decompensated heart failure with low output and signs of hypoperfusion, this medication class is used short-term to improve contractility.
What are inotropes (e.g., dobutamine, milrinone)?
These two ABG findings suggest acute-on-chronic respiratory failure.
What is elevated PaCO₂ with low pH?
This is the empiric antibiotic regimen for inpatient, non-ICU CAP without risk factors for MRSA/Pseudomonas.
Preferred: What is ceftriaxone (or ampicillin-sulbactam, cefotaxime) + macrolide (or doxycycline)
Monotherapy: What is a respiratory fluoroquinolone?
This mechanical complication of MI can present with new harsh systolic murmur and cardiogenic shock within 5–7 days.
What is ventricular septal rupture?
In bradycardia with poor perfusion, this medication is first-line after atropine fails.
What is dopamine or epinephrine infusion?
This hemodynamic profile, described as “cold and wet,” refers to these two key clinical features in acute decompensated heart failure.
What are hypoperfusion and volume overload?
This lung function value is used to grade COPD severity.
What is FEV₁?
This is the time that has passed when considering additional antibiotic coverage for Pseudomonas or MRSA colonization.
HINT: Dr. Hicks mentioned this, which is different than IDSA guidelines.
Dr. Hicks: What is 6 months?
IDSA: What is 1 year?
This post-MI complication results from free wall rupture, leading to rapid pericardial effusion and tamponade, and is most common 5–14 days after transmural MI.
What is left ventricular free wall rupture?
This is the maximum cumulative dose of amiodarone that can be given during cardiac arrest according to ACLS guidelines.
What is 450 mg (300 mg initial bolus + 150 mg additional dose)?
This invasive measurement obtained via right heart catheterization is elevated in cardiogenic shock and reflects left ventricular end-diastolic pressure.
What is pulmonary capillary wedge pressure (PCWP)?
This imaging finding is characteristic of advanced emphysema, showing destruction of alveolar walls and hyperinflated lungs.
What are bullae?
This is the empiric antibiotic regimen for inpatient, ICU CAP with risk factors for MRSA and a recent history of Pseudomonas colonization.
What is Vancomycin (or Linezolid)?
What is Cefepime (or piperacillin-tazobactam, Ceftazidime, Imipenem, Meropenem) + macrolide (or doxycycline, respiratory fluoroquinolone)?
