AI in Anesthesiology Quiz

Answers and explanations appear as you take the quiz.

1. What does the Hypotension Prediction Index estimate?
   • The chance that mean arterial pressure will fall below 65 mmHg in the next few minutes
   • The depth of the patient's sleep after surgery
   • The patient's oxygen level tomorrow
   • The total dose of propofol needed
2. What data does HPI analyse to make its prediction?
   • Patient questionnaires
   • Chest X-rays
   • The shape of the arterial pressure waveform
   • Genetic test results
3. What did the HYPE trial, published in 2020, find?
   • HPI eliminated all surgical complications
   • Patients spent less time hypotensive when HPI guided care
   • HPI increased time spent hypotensive
   • HPI was withdrawn from the market
4. What is a key critique of HPI's reported accuracy?
   • It does not use any blood pressure data
   • It only works on children
   • It requires a brain implant
   • It is strongly correlated with current mean arterial pressure, which may overstate its added value
5. In closed-loop propofol research systems, what signal is commonly used as the control target?
   • Bispectral index (BIS)
   • Body temperature
   • Urine output
   • Blood sugar
6. What happened to the Sedasys sedation system?
   • It became the standard for all general anesthesia
   • It was never approved by the FDA
   • It was approved in 2013 but withdrawn by its maker in 2016
   • It was banned for causing deaths
7. Which safety feature is expected in a well-designed closed-loop anesthetic system?
   • Removing the clinician from the room
   • Hard limits on infusion rates and fallback to manual mode
   • Disabling alarms to avoid distraction
   • Ignoring sensor artefacts
8. What models does target-controlled infusion use to estimate drug concentration?
   • Pharmacokinetic-pharmacodynamic models such as Marsh or Schnider
   • Large language models
   • Weather forecasting models
   • Credit scoring models
