Cardiac Output is a podcast on cardiothoracic anaesthesia and intensive care medicine by Dr Mike Charlesworth and Dr Calum Downes.

Delighted to receive a mention in @Assoc_Anaes @Anaes_News!🎙️

The rule we set ourselves is that anything a listener could find in a textbook gets thirty seconds, and the remaining time goes to the things you would otherwise only learn by being in the room.

Cardiac Output Monitoring: Believe the Patient.

This episode is cardiac output monitoring, for the exam and for the bedside: how each device works, the physiology underneath, when we actually use them, and where each one misleads you.

@dorcodoc Thank you! Spread the word! 😊

Cardioplegia makes planned ischaemia survivable in five ways — arrest, cool, empty, feed and buffer, and limit reperfusion injury — and arrest does most of the work.

This is atrial fibrillation on the cardiothoracic ICU, top to bottom. And it matters beyond the bedside: in a recent @RCoANews Fellowship paper it was the worst-performing question on the whole exam, with a pass rate of about 43 per cent.

TOE in Theatre: The Probe Earns Its Keep.

A foundation guide on the use of TOE for cardiac surgery – EF, the RV, wires/pipes and much more!

Today it's transthoracic echo on the intensive care unit: the views, and the patterns you are looking for in a shocked patient.

TOE for Mechanical Support 2: VADs and the Impella.

People say "VAD" and mean five different machines, sitting in different places, for different lengths of time.

TOE for Mechanical Support 1: Balloon Pumps and ECMO.

In mechanical circulatory support, transoesophageal echo is not an investigation you order. It is part of the device.

Cardiopulmonary Bypass: What It Does to the Patient.

This is cardiopulmonary bypass top to bottom, pitched at @RCoANews FRCA level and a little beyond, and built around the questions that have actually appeared in past papers.

Intra-Aortic Balloon Pumps: Timing, Traces and Trials.

The answer isn't to ignore the evidence — it's to notice what the trials actually studied, which was routine, unselected use in two specific shock populations.

Today, we are featuring the @ITACStrial by @TobyRichardsUEL et al. published recently in @bmj_latest.

Probably the most important cardiac anaesthesia trial published in 2026 so far? We think so!

Protamine: The Most Dangerous Drug We Give Every Day.

Cardiac surgery consumes around ten per cent of the entire NHS blood supply, and ninety per cent of those products go into ten per cent of patients.

[Cardiac Output @CardiacOutputMC]

Bleeding After Cardiac Surgery: Products, TEGs and HIT.

Mike takes a deliberately unfashionable position on the TEG and defends it, and Calum pushes back.

Endocarditis Surgery: Timing, Bleeding and Vasoplegia.

Prosthetic valve endocarditis carries around a 27% one-year mortality, with device-related disease closer to a one in four risk of not getting home at all.

[Cardiac Output @CardiacOutputMC]

In this episode Mike and Calum work through infective endocarditis
-why it presents so differently now
-how it gets diagnosed
-the traps that make it harder than it needs to be.

TAVI for Residents: Evidence, Rapid Pacing and Sedation.

"And here's what I'd add, which matters more than any drug choice.

Be deliberate. Be patient. Be gentle."
