    00:01 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.

    01:43 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.

    02:02 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 ventilatory support? Like Bi-PAPs and stuff? Not for part A. No, no, no, no. For part B, there is.

    02:16 There is a critical skill station.
