Know the physiology before you induce it.
EASy was developed by an anesthesiologist-intensivist for the moments anesthesia owns: the unstable induction, unexplained perioperative hypotension, and the arrest under drapes.
The riskiest minutes in anesthesia are transitions: induction of the patient whose blood pressure is a guess, the sudden intraoperative hypotension with a covered chest, the arrest where the surgical field owns the sternum. These are exactly the moments when a full echocardiographic study is least available.
A physiologically difficult airway is a hemodynamic problem wearing an airway's clothes. Knowing whether the patient in front of you is empty, failing, obstructed, or tamponading — before the propofol — changes the induction plan more than any airway score.
Acquire. Phenotype. Act.
Acquire
The subcostal window stays accessible when anesthesia needs it most — under drapes, during compressions, in the ventilated chest — and the exam runs on the phased-array probe already on your machine.
Phenotype
Heart, IVC, and lung findings integrate into one of ten hemodynamic phenotypes: a pre-induction physiology statement you can hand to the room, not just a stack of views.
Act
The phenotype shapes the plan — induction agents and doses, vasopressor readiness, fluid strategy — and names when the focused exam is insufficient and a fuller study or another window is required.
Where EASy fits in your practice
The physiologically difficult airway — EASy PDA
A pre-induction phenotype for the patient who may not tolerate induction as planned.
ExplorePerioperative hypotension — EASy MAP
The core protocol for the hypotensive patient, before, during, or after the case.
ExploreArrest under anesthesia — EASy ALS
Reversible causes from the subcostal window while CPR continues.
ExploreAverage examination time for novice sonographers in the published comparison. A protocol that costs a quarter of the time gets repeated when the patient changes.
Fiorini & Basmaji, Can J Anaesth 2022After one day of focused training, novice residents obtained images sufficient for supervised clinical decision-making in 87% of 63 examinations — averaging 4.3 minutes each. Day one is about acquisition; interpretation stays supervised.
