Significant challenges exist in measuring ventilation quality during out-of-hospital cardiopulmonary arrest (OHCA) outcomes. Since ventilation is associated with outcomes in cardiac arrest, tools that objectively describe ventilation dynamics are needed. We sought to characterize thoracic impedance (TI) oscillations associated with ventilation waveforms in the Pragmatic Airway Resuscitation Trial (PART). ⋯ Compared with LT, ETI thoracic impedance ventilation insufflation and exhalation amplitude were higher while duration did not differ. TI may provide a novel approach to characterizing ventilation during OHCA.

Patients with sudden cardiac arrest occurring in the acute phase of myocardial infarction (MI-SCA) are believed to be at similar risk of death after revascularization compared with MI patients without SCA (MI-no SCA). Among patients with anterior MI, we examined whether those with MI-SCA were at greater risk of all-cause mortality or sudden cardiac death (SCD) than MI-no SCA patients. ⋯ Patients with MI-SCA had similar adjusted risk of all-cause mortality and SCD compared with MI-no SCA. After ICD implantation, MI-SCA patients had higher mortality compared with MI-no SCA patients.
