Sure, I’d be happy to look it over. What’s the main structure you’re using, and which parts are you most concerned about? Maybe we can go through each step together and see if anything feels a bit out of place.

I’ll take a close look at the decision nodes you’ve written. The first thing that jumps out is the SpO₂ threshold you’re using for the “urgent” red‑flag branch—most current guidance recommends keeping the cutoff at 94 % for adults and 92 % for patients with pre‑existing lung disease. If you’re still using 90 % you might be missing a few patients who need faster intervention. Next, the COVID‑19 isolation criteria: the tree still lists a single‑minute oxygen desaturation of 3 % as the trigger for isolating a patient, but the latest CDC update now recommends using a 5 % drop or a nadir below 93 % as the more reliable marker. The symptom list for “respiratory distress” also needs a tweak. You’re currently flagging “rapid breathing” as anything above 20 breaths per minute, but the new protocol expands that to 22  breaths in adults who are older than 65 or who have chronic heart or lung conditions. Lastly, the “chest pain” node is still using the old rule that any chest pain automatically pushes to the ED. The updated algorithm says that if the pain is stable, non‑radiating, and the ECG is benign, a lower‑risk triage could be acceptable—especially when the patient is otherwise asymptomatic for COVID. So if you adjust those thresholds and add a quick check for the 65‑plus/Chronic‑condition modifier, the tree should align with the current guidance. Does that make sense?

Sounds like a solid plan—looking forward to seeing the updated tree. Just let me know when you’re ready, and I’ll give it another quick look.
