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.
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.
You’ll notice the big spikes that you see
here in the graph are the ventilator breaths.
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.
Let's continue. Okay. Now, what is this
pressure support? Well, we have two different
