1 · Find evidence

PubMed query

Every result is a real PMID returned by NCBI. Nothing on this step is generated.

Ask OpenEvidence ↗

OpenEvidence opens in your own logged-in session with the question filled in. Nothing is fetched on your behalf — read it there, then add what you want to teach as a point below, citing the source it came from.

31 candidate papers

Ticked papers are the ones a deck may be built from. Unticking one needs a reason — the citation gate proves a paper exists, and nothing but you decides whether it should be taught. A tier badge appears where the paper’s publication type is known.

Same-day build

PubMed query

Runs the tiered searches, drafts one point per included paper, runs the citation gate and builds a draft deck — the steps below, unattended. Same-day build — drafted locally (medgemma:27b), confirmed against each abstract. The deck still lands in draft: nothing here approves anything.

2 · Teaching points

Source

A point with no source will not survive the gate. That is the point of the gate.

Mean arterial pressures below 60-70 mmHg are associated with myocardial injury, acute kidney injury and death, and the injury is a function of both how far the pressure falls and how long it stays there. PMID 30916004 kept
Organ injury is reported after 10 minutes or more below a mean arterial pressure of 80 mmHg, after shorter periods below 70 mmHg, and at any exposure below 55-50 mmHg. PMID 30236233 kept
Hypotension on the four days after surgery carried a far stronger association with myocardial infarction and death (odds ratio 2.83) than each extra 10 minutes of intraoperative hypotension (odds ratio 1.08). PMID 29189290 kept
Cumulative intraoperative norepinephrine dose is independently associated with postoperative acute kidney injury, so escalating vasopressor to chase a pressure target is not a risk-free trade. PMID 39672776 kept
Targeting a MAP of at least 75 mmHg instead of 60 mmHg cut time spent below 65 mmHg by roughly 60% but did not reduce acute myocardial injury or 30-day major cardiac events and acute kidney injury. PMID 34711333 kept
A maximum intraoperative heart rate above 100 bpm together with a minimum systolic pressure below 100 mmHg is more strongly associated with myocardial injury than low systolic pressure alone. PMID 29077608 kept

Checks every citation against PubMed, the DOI resolver, or a live fetch. Points that do not resolve are dropped and shown to you with the reason — never quietly softened.
