Heart Failure: Left vs. Right
Meet Mrs. Alvarez. She wakes up at night gasping for air and has to sleep sitting up on three pillows. When Nurse Nia listens to her lungs, she hears crackles.
Left = Lungs: crackles, shortness of breath, cough.
Right = Rest of the body: swollen legs, weight gain, neck vein swelling.
If the question mentions crackles or pink frothy sputum, think left-sided failure.
Clear, cute and easy to follow
Every page is made to be read in minutes, with color-coded tips, memory tricks and test clues you can spot at a glance.
