JC: Manual pressure augmentation during cardiac arrest: another lesson in physiology versus outcome
St Emlyn's28 Aug 2026Cardiac Arrest
Clinical takeaway
A favourable physiological surrogate is not enough to support routine manual pressure augmentation during cardiac arrest when patient-centred outcomes have not improved.
EDCritix summary
This critical appraisal reviews the AUGMENT-VA randomised trial: manual pressure augmentation lowered transthoracic impedance during defibrillation but did not improve survival to hospital discharge.
