The PONV risk calculator turns the Apfel score into something you can actually use between cases — no mental math, no memorized incidence table, just four taps and an answer.
Tap the risk factors that apply — female sex, a history of PONV or motion sickness, nonsmoker status, planned postoperative opioids — and watch the score build live on a color-coded gauge, running from green at low risk through gold, orange, and red as risk climbs. No guessing what a color means: a plain-language risk tier and the actual incidence percentage sit right below it.
Below the score, you get a tiered prophylaxis recommendation pulled straight from the Gan Consensus Guidelines — the specific antiemetic classes to reach for at that risk level — plus a teaching note on the baseline-risk moves (TIVA, minimizing opioids, skipping nitrous) that stack on top of any drug regimen.
