Anatomical Lungs Emoji

As a follow-up to my labeled anatomical heart emoji, I give you the lungs! Also from the Emoji 13.0 list.

Breathing Patterns

A patient’s breathing pattern can help guide response to therapies and diagnostics. Normal breathing is regular and comfortable at a rate of 12-20 breaths per minute (bpm). Tachypnea and bradypnea have rates above and below...

West’s Lung Zones

Alveoli that are well ventilated (V) should be associated with good pulmonary capillary blood perfusion (Q) to maximize gas exchange. This is the idea behind V/Q matching. Gravitational forces create heterogeneity perfusing dependent portions...

Percutaneous Tracheostomy

Percutaneous tracheostomy ("perc trach") is a procedure that is routinely performed at the bedside on patients who require prolonged mechanical ventilation or airway control due to an upper airway obstruction or for pulmonary hygiene....

Subcutaneous Emphysema

Subcutaneous emphysema occurs when air gets trapped within the subcutaneous regions of the face, neck, chest wall, abdomen, and even down to the thighs/legs. The characteristic physical exam finding of crepitus ("snap-crackle-pop") is caused...

Prone Chest X-Rays

In severe COVID-19 pneumonia with refractory hypoxemia, patients are often proned (put on their abdomen), deeply sedated, and paralyzed to improve synchrony with the ventilator. The goal with proning is to create a more...

Deep Sulcus Sign

A pneumothorax occurs when air fills the pleural space between the lungs and chest wall. This can cause partial or total lung collapse leading to difficulties with alveolar ventilation, hemodynamic lability, etc. If a chest...

Tension Pneumothorax

Here's an example of a large, right-sided tension pneumothorax (PTX). Disruption in the lung leads to a one-way valve where air fills the pleural space and expands the PTX during inspiration but cannot escape...
