    Let's continue taking a look at respiratory failure and now however, you know how the ECG or EKG was for the cardiovascular system. Well, it’s just as important that you take at look at the graphical presentation of what is known as your ventilation or modes of in respiratory failure. We will begin by looking at the foundation of setting up what you want to be very familiar with when you are interpreting graphs of modes of ventilation. What does that even mean? Well, there are two modes, in general, that you would be able to help your patient with respiratory failure. You are extremely familiar with one of them which is the management of a patient that has obstructive sleep apnea. Think about that patient who is obese and maybe has a hard time breathing out and so therefore might be, wow, apart from hypoxemia might also be then retaining carbon dioxide. So with this patient, you might want to think about providing this patient with what is known as a mode of non-invasive ventilation and this is referred to as being CPAP and that you already are familiar with. What CPAP stands for is continued positive airway pressure. Now on that note, what we will take a look at is, well, non-invasive versus invasive. What, really, what is the difference and how does that then benefit you? Say at some point, you do need to intubate your patient, right, endotracheal. You need to intubate your patient, then here, the graphical representation which will be your ventilation graph through invasive will be quite important for you to interpret. So, just like we looked at pulmonary function test as being non-invasive, let's begin by dissecting our graphs. The graph that you see in the bottom is pressure. And how would...
