The respiratory severity score is one multiplication most of us already do in our heads, mean airway pressure times FiO2. This week Dr. Dinushan Kaluarachchi joins Journal Club to walk through three papers built on it, RSS trajectories across gestational age in the PROP cohort, an RSS based grading of BPD at 36 weeks, and RSS after 40 weeks as a predictor of tracheostomy. He also talks about writing that last paper with his son, a high school junior, and why a brief communication is a realistic on-ramp for students. Plus a preview of two upcoming trials, including surfactant given through a supraglottic airway.
