Case reports suggest cough may sustain output in arrest; hypothesis-generating and should not change practice without validation.
Does vigorous coughing maintain systemic perfusion and consciousness during ventricular fibrillation?
Vigorous coughing during ventricular fibrillation can maintain systemic perfusion and consciousness, likely via increased intrathoracic pressure compressing the pulmonary vascular bed.
Niemann et al. (1980) studied this question.
