Free teaching resources
Eleven simulators and a 13-module curriculum. Free, in your browser, no account needed.
Every simulator is marked Preview. They are working drafts — usable now, still being built and revised. If something looks wrong, tell me.
Thirteen interactive web-based modules teaching multi-organ point-of-care ultrasound image acquisition and interpretation.
Free. A short registration sends you the module links by email.
POCUS
Seven organ systems on a shared imaging engine. Every image is computed from a model of the anatomy rather than replayed from a recorded clip, so the picture changes as you move the probe.
Place the probe. Aim the plane. Find the view.
Transthoracic cardiac ultrasound from the parasternal, apical and subcostal windows: PLAX, the short-axis levels, the apical views, subcostal four-chamber and the IVC.
Ribs and lung are modelled and they shadow, so finding a clear window is part of the score. Supine or left lateral decubitus; screen orientation switches between the cardiology and EM conventions.
Explore freely, or Acquire a named view and be scored on how close your plane lands.
Open the simulator →Move the probe. Watch the plane. Find the view.
Drive a TEE probe with its real controls — omniplane, flexion, advance, withdraw and rotation — and see where the imaging plane falls. Standard views follow the ASE/SCA guidelines.
Three modes: Explore freely, Acquire a target view for a score, or Identify a view from the image. Biplane imaging included.
Open the simulator →Find the window. Follow the pleura. Read the pattern.
A six-zone supine exam with the linear, sector and curvilinear probes, B-mode with M-mode when you want it, and five lung phenotypes to tell apart.
Acquire asks you to optimise the view and record a full breath cycle. Read gives you ten animated clips with the probe settings hidden until you commit to an answer.
Open the simulator →Find the antrum. Measure it. Estimate the volume.
Slide, rotate, fan, rock and press on a supine or right-lateral patient, with the stomach, pancreas, aorta and IVC shown in 3D beside the image so you can see where your plane is cutting.
Explore, Acquire and Measure. Volume comes from the Perlas formula, and the score reflects both the plane you found and the calipers you placed.
Open the simulator →How little free fluid can you still see?
The peritoneal views of the FAST exam — right upper quadrant, left upper quadrant, pelvic transverse and pelvic sagittal — on a case you build yourself.
Set free fluid anywhere from nothing to two litres, seed it diffusely or into one quadrant, then change the patient’s sex, bladder fullness and tilt and watch where the fluid goes.
Engine preview: the planes and the physiology are calibrated; probe controls, scoring and reading rounds come next.
Open the simulator →Grade the hydro. Read the bladder.
Both kidneys in long and short axis and the bladder in two planes, on a case you configure: hydronephrosis in four grades, kidney size, cortical thickness and echogenicity, cysts, stones and masses.
The bladder runs from empty to distended, with wall thickening, clot, a Foley balloon in or out, and male or female pelvic anatomy.
Engine preview: probe controls, Acquire scoring, Measure and the reading rounds arrive in the next versions.
Open the simulator →Press and hold. The vein either flattens or it doesn’t.
Proximal lower-extremity compression ultrasound at six calibrated points from the common femoral vein to the popliteal, plus a sweep down the femoral vein for the clot that hides between them.
Compression is under your hand: the vein flattens, the artery indents, and the app calls it compressible, non-compressible, or not pressed hard enough. Occlusive, non-occlusive and acoustically invisible clots, with a lymph node, a Baker’s cyst and a nerve as mimics.
Engine preview: the six points and the compression physics are calibrated; the full probe interface and reading rounds come next.
Open the simulator →ICU
Read the scalars. Name the mode. Name the problem.
Twenty-seven cases, basic to advanced. Pressure, flow and volume scalars appear alongside the dialed-in settings; you name the mode and the abnormality. Waveforms are computed from a respiratory model, not drawn by hand.
Calipers, zoom, and 2-, 4- and 8-second sweep windows.
Open the trainer →Change the device. Watch the physiology respond.
A live closed-loop hemodynamic model of mechanical circulatory support: VA-ECMO, VV-ECMO, V-AV ECMO, Impella, HeartMate 3 and temporary RVADs. Bedside gases, echo, labs and hemodynamics sit on separate dashboards.
Three experience levels; simulation speed adjustable up to 10×.
Open the simulator →Arrest after cardiac surgery. Decide what happens next.
An interactive simulator for managing cardiac arrest in the post-cardiac-surgery patient.
Open the simulator →Anesthesia
One component has failed. Find it.
An anesthesia machine and ventilator with live pressure, flow, volume and capnography. In each scenario exactly one component has failed in the machine, circuit or patient interface; you find it from the waveforms and the dialed-in vs measured mismatch.
Three difficulty tiers, plus concept questions on gas physics, absorber chemistry, scavenging, cylinder math and safety interlocks.
Open the simulator →Separation from bypass is a sequencing problem.
Assemble the order of 27 events across surgeon, perfusionist, anesthesiologist and shared roles. The engine grades precedence and safety, not style.
Learn and Exam modes, a reference timeline anchored to the venous clamp, and seven “never events.” Built with input from a group of senior cardiac anesthesiologists.
Open the trainer →Cardiac anesthesia also uses the TEE Probe Simulator, listed above with the ultrasound simulators.
The simulators are teaching models, not diagnostic or clinical decision tools. No account is needed to use them.
