Key result
Rhythmic coughing generates femoral arterial pressure pulses during induced ventricular fibrillation compared to no coughing.
Key points are not available for this paper at this time.
Comparison
Rapid, regular coughing vs slower, irregular coughing vs no coughing during induced ventricular fibrillation
Design
Other
Coughing may preserve femoral pressure during induced VF; hypothesis-generating for cough CPR and requires prospective validation before clinical consideration.
Femoral arterial pressure before and during induced ventricular fibrillation during implantable defibrillator threshold testing demonstrates control blood pressure (A); rapid, regular coughing (B); slower, irregular coughing (C); and no coughing (D).

Girsky et al. (2006) studied this question. Coughing during induced ventricular fibrillation alters femoral arterial pressure, with variations observed between rapid regular coughing, slower irregular coughing, and no coughing.
