No CAP, but this is the most common cause of community-acquired pneumonia requiring hospitalization.
What is Streptococcus pneumoniae?
What are bronchodilators?
What is dyspnea?
This oxygen delivery device provides the highest FiO₂ among common ward devices.
What is a non-rebreather mask?
The image demonstrates the silhouette sign, obscuring the right heart border, which suggests that the pathology going on can be found in this part of the lung

The patient looks septic and looks shocky… while we’re calling Dr. Schwartz and Co., let’s go ahead and start this, thankfully we don’t need central access.. yet
What is norepinephrine (Levophed)?
A positive urine antigen test is most commonly used to diagnose this atypical pneumonia pathogen
What is Legionella pneumophila infection?
This therapy reduces mortality in our COPD patients. Seems simple enough I guess
What is oxygen therapy (long-term)?
This is the most common ECG finding in a PE… again don’t overthink it.
What is sinus tachycardia?
Elevated PaCO₂ defines this type of respiratory failure
What is hypercapnic respiratory failure?
Blunting of the costophrenic angle(s) indicates

What are pleural effusions?
What is lactate?
Sometimes patients develop a lung infection after you tried protecting the airway and lungs for a week. It be like that sometimes. This would be classified as this
What is a ventilator-associated pneumonia?
COPD patient has pH of 7.28 and a CO2 of 68 and needs this. Don’t worry, the VA ED is calling the MICU to admit because they gave this much needed intervention to help with respiratory and CO2 off-loading
What is non-invasive ventilation (i.e. BiPAP)
Everyone’s favorite test. It’s primarily used to exclude PE in appropriately selected low-risk patients.
What is d-dimer?
PaO₂ <60 mmHg defines this type of respiratory failure.
What is hypoxemic respiratory failure?
Woah, someone put too much air in these baloons (or lungs)! Hyperinflated lungs with flattened diaphragms usually suggests this type of COPD/lung disease

What is emphysema?
Dang, the norepinephrine/levophed didn’t work. Gotta call in this back up, the most commonly added second-line vasopressor in septic shock
What is vasopressin?
Things are not golden when you have this severe pneumonia, most likely due to this pathogen
What is Staphylococcus aureus?
Silence is golden… except when it’s an asthma patient. It’s concerning for this.
What is impending respiratory failure?
Isn’t this cardiac? So then why do I need these biomarkers to help stratify the risk of pulmonary embolism according to recent AHA/ACC guidelines?
What is BNP and troponin?
A COPD patient receiving excessive oxygen may develop worsening hypercapnia due to this mechanism.
What is worsening V/Q mismatch?
A visible pleural line with absent lung markings peripheral to it indicates this pathology

What is a pneumothorax?
Low tidal volume ventilation improves outcomes in this ICU syndrome
What is ARDS?
It’s bad luck when you have recurrent pneumonia, especially in the same lobe. Either the bugs really love this spot, or you should really evaluate and rule out this
What is obstructive lesion (or malignancy)?
The GOLD classification of COPD relies primarily on this pulmonary function test measurement.
What is FEV1?
First-line treatment for most stable PE patients
What is anticoagulation?
A patient with obesity, daytime somnolence, and chronic hypercapnia most likely has this condition.
What is obesity hypoventilation syndrome?
“ITS SO FLUFFY IM GONNA DIE”, says Agnes from Despicable Me, but so will your patient because of this condition they have, suggested by the CXR.

What is ARDS?
It’s 2 AM, and your COPD patient on BiPAP develops worsening acidosis, rising PaCO₂, and declining mental status… Yikes. Let’s get ready to do this intervention
What is endotrachael intubation?
