Yeah okay. But you need to know about ARDS in terms
of theory. What's ARDS? How do you diagnose
ARDS? So it's a syndrome of respiratory failure,
and the crucial word is non-cardiogenic pulmonary
oedema. So it's not related to cardiac cause,
there’s pulmonary oedema. Why? Why do you
get pulmonary oedema without cardiac failure?
Leaky capillaries. Endothelial leak similar
to the burns we discussed. Leaky capillaries,
it's all accumulating in the lung and the
lung becomes refractory to oxygen. So there's
loss of surfactant. So the lung is pretty
much dead, it’s not functioning.
This is the definition. Diffuse pulmonary
infiltrates on chest x-ray. They say the Kerley-B
lines. Kerley-B lines. Wedge pressure less
than 18 or in the absence of the left atrial
hypertension. So these are all theory, but
you need to have an idea of what is ARDS.
This again, theoretical slide, which
will be available. But for the purpose of your
course you need to get a good understanding
of what is ARDS? How do you manage ARDS? And
what's the mortality of a fully blown ARDS?
Very high. Yes, yes it's nearly fifty percent,
forty to fifty percent is the mortality of
a full blown ARDS. What is the management
of ARDS? Ventilation,
intensive care, ventilation, ventilatory support.
There's a role for nitrosamine, steroids.
Then you have to nurse the patient prone.
So these are the options you may get in your
exam. But you need to have a bit of idea how
do you manage ARDS. Prone, nitrosamine.
But I don't think you'll be asked
that specific. But they may ask you, putting
the patient prone. Can we be asked about
Like Bi-PAPs and stuff? Not for part A. No,
no, no, no. For part B, there is.
There is a critical skill station.
