The tongue falling back into the throat.
What are the signs and symptoms of hypoxia?
Symptoms may include confusion, restlessness, and cyanosis.
What are oxygen adjuncts, flow rates, and percentage of oxygen delivered?
Devices and methods used to provide supplemental oxygen.
What is pleural effusion?
The accumulation of fluid in the pleural space.
What is albuterol?
A medication used to treat bronchospasm.
What is alkalosis?
A condition characterized by an excess of base in the body fluids.
What is wheezing?
A high-pitched sound made while breathing, often indicating airway obstruction.
What are rales?
Abnormal lung sounds, often described as crackling or rattling.
What are rhonchi?
