You are doing a sustained inflation on a patient and notice that their BP has started to drop. This is likely because:

Which sonographic artifact is being demonstrated in this image?

This image was taken in which anatomic plane?

Looking at the same graph as question 11, what would be the best way to treat this?

After a few days your patient has improved and has been changed to the following settings: PSV 14 PEEP 8 FiO2 40% Her RR is 24, and Vt is approximately 450 mls. Your co-worker does an Inspiratory hold and the Pplat is 28. From this you determine that:

A few hours later you are looking at her etCO2 waveform you see the following waveform. What do you think is happening?

From the location demonstrated in the image below, which direction do you have to sweep/angle the beam to visualize the pancreatic tail?

You have a patient on PSV of 14, 45% FiO2 and Peep of 6. Their RR is 24 and their Vt is 450 ml. You are concerned that they might be airtrapping, how might you determine this?

Explain three variables that we can assess to see if our recruitment maneuver was successful. Also explain three contra-indications to performing a recruitment maneuver.

For the next eight questions use the case study presented below: You have just intubated and initiated ventilation on a 33 year old male brought in by paramedics. IBW is estimated at 80 kg, actual weight is 233 kg. On arrival in ER and prior to intubation he was unresponsive with a RR of 4 and barely audible breath sounds. SpO2 was 82% on NC 6lpm. The most likely reason for his poor oxygenation pre-intubation would be:
