Periodically case studies emerge that demonstrate voluntary and forced coughing in ventricular fibrillation or asystole can maintain consciousness for up to 100 s. Forced cough is effective in producing co-ordinated abdominal muscle contraction and increases in intra-abdominal and thoracic pressures. These co-ordinated pressure changes are likely to be responsible for assisted circulation. In this short communication we discuss some of the possible abdominal physiological mechanisms for cough assisted circulatory support.
