1.A primer on airway obstruction in #Sedation @pedsedation @PediAnesthesia @hyguruprep #MedTwitter
Lets focus on hypo-pharyngeal collapse & Laryngospasm
First lets review the Starling resistor model for airway obstruction (Butler JP et al. J Physiol. 2013 May 1;591(9):2233-4) 2. The nasal & tracheal structures support a collapsible segment-supraglottic area (CN IX, X & XII innervation).Sedatives inhibit tone of this segment with propensity to collapse more. The collapse can be exacerbated by diaphragmatic contraction (inspiratory negative pressure).

To all who responded to our question from 8/20 a big thanks. Here is the answer and a short thread:
First the question: 15-year old with dyspnea, tachycardia, and hypotension. COVID-19 stuff is negative. Whats abnormal in the CVP tracing? Next step in definitive management is? 1) #pedsicu fellows etc. knowledge of what any normal waveform looks like is essential to tackle the abnormal. Don't worry y'all will learn more of this as you go through your fellowship training. Lots of awesome resources out there:- @OPENPediatrics learnpicu.com
