1. Airway: Answer -how we get air into the lungs -when we are talking about the airway, we are most concerned with patency ^in our patients who are in critical condition or even patients in emergent situations, one of the first things we will assess for is airway obstruction -the tongue is a pretty good culprit of airway obstruction, especially in patients who have an altered level of consciousness -a sure-fire way to maintain patency of the airway is through intubation 2. EndotrachealTube (ETT): Answer -we can see that the endotracheal tube is placed within the airway -the esophagus is on the posterior side and the trachea on the anterior -the tube is a foot to a foot and a half long -it passes through the mouth and then through the vocal cords -a balloon is inflated to separate the upper and lower airway ^the balloon is not completely imperviousto secretions,so we need to keep the HOB elevated -our job is to make sure that the tube has the correct placement ^in the lungs, not the abdomen 3. Breathing: Answer -airtravelsthrough the trachea and then it makesits way to the alveoli for gas exchange! -carina: tracheal bifurcation for the right and left lungs ^the right main stem is a little bit straighter than the left one, so if the ETT is pushed too far then it can exclusively enter the right tract ^if this happens, only one lung is being oxygenated (this is why it is important to listen to the lung sounds of intubated patients) 4.
