Ventilating Asthma or COPD? I:E is not the Goal by Steve Haywood
- Intubated patients with severe obstructive lung disease can be some of the most challenging to manage. Continue to dose albuterol and treat the underlying disease.
- You may have to hit the reset button while you optimize the ventilator.
- You may be able to increase the tidal volumes if the plateau pressures are low.
- As paralytics are added and spontaneous inspiration is removed, the respiratory mechanics change and turbulent flow may be reached at higher inspiratory times.
- The rate may need to be lower even more. As you treat the disease, you may be able to increase the rate.
- Look at your I:E ratio. You need to get it low (1:5 or lower), but do not fixate on it. It is all about giving the patient as much time as possible to exhale.

UltraRounds: Knobology by Segun Olusanya
- Pearl #1: Good image quality is not just helpful for you to make better diagnoses, but for everyone to be able to make those diagnoses with you.
- Pearl #2: Have what you are looking for in the center of the screen, as big as possible, and as smooth and as clear as possible.
- Pearl #3: Think about depth, gain, focus, and sector width every time you are imaging a body structure.
The Vitals: Central Venous Pressure by Michael Javid
- CVP is not appropriate for guiding fluid therapy; there are numerous other methods to assess for fluid responsiveness
- Consider using it when you are concerned for right ventricular function
A Push for a (First-Dose) Push by Rachel Rafeq
- IV push is likely a feasible option for the first dose of antibiotics
- Speak with your pharmacists to ensure that the concentration is less than 900mOsm/L
- Check out the post for a handy chart that helps you convert common antibiotics into push-dose versions!
