What is the purpose of a cuff on an Endotracheal tube?

|
1-5 Lpm (II.A.1.)

|
How does pulse a pulse oximeter work?
|
Small beams of red and infrared lights pass through the blood in the finger to measure oxygen saturation levels (I.C.2.)
|
 What does DLCO measure? |
It measures how much oxygen travels from the alveoli of the lungs to the blood stream (I.A.6.)

|
A trauma patient arrives to the ER and is now in the process of being intubated. When you try to inflate the cuff you notice that it is not inflating, what do you do next?

|
Pressure waveform (III.B.4.)
|
