Ventilation

Critically unwell patients often present with inadequate oxygenation and ventilation, in this episode we’re going to explore some of the physiology of critical illness, look at how we can improve oxygenation and ventilation, take a look mechanical ventilation and have a think about how we can deliver this to a really high level.

We’ll be covering the following;

• Type 1 & 2 respiratory failure
• Breathing assessment
• Optimising patients own ventilation
• Mechanical ventilation
• Modes of ventilation
• Setting up a ventilator; tidal volume, RR, FiO2, I:E ratios, dead space
• End tidal CO2
• Optimising oxygenation & ventilation
• Hand ventilation
• Ventilation in cardiac arrest

Once again we’d love to hear any thoughts or feedback either on the website or via twitter @TheResusRoom.

Enjoy!
