Modes of Ventilation: Intermittent Mandatory Ventilation

00:00 Let's take a look at another type. Now, all these names that you see here, allow it to speak to you. IMV means intermittent mandatory ventilation. So what does this mean? Well I want you take a look at the graph yet once again. On the X-axis, represents time, concepts first. On the Y-axis, is the volume. What does that mean? Well, the more volume that you put in your lung, you tell me what the patient is doing. Good. Inspiration, isn’t it? That is volume. In the mean time, all the pressure be doing in the in-vivo, inside the patient.

00:38 It will be negative pressure which will then be the trigger for air to come in. You understand how important it was, for you to make sure that you understood your physio there. You as a clinician, wish to help your patient, assisted control. So therefore, you are going to introduce what? Good. Positive pressure. Now, the SIMV that you see on the graph means synchronous intermittent mandatory ventilation. And what this represents that ever so often after a certain number of breaths intermittently, there is going to be air that you are going to introduce to your patient and hence, increase the amount of ventilation that you then wish to provide for your patient. Keep it simple, at this point. At least lay down the foundation.

01:24 You’ll notice the big spikes that you see here in the graph are the ventilator breaths.

01:31 The little humps that you see there, the little mounts in between the spikes represents the patient breath. So, this means that this is a patient who requires, assistance. Welcome to intermittent or synchronous intermittent mandatory ventilation. Be familiar with the terminology, it will come in extremely handy for you so that you are not lost when you are reading a clinical vignette.

01:57 Let's continue. Okay. Now, what is this pressure support? Well, we have two different
