Cough-cardiopulmonary resuscitation in the cardiac catheterization laboratory: hemodynamics during an episode of prolonged hypotensive ventricular tachycardia

Cathet Cardiovasc Diagn. 1989 Nov;18(3):168-71. doi: 10.1002/ccd.1810180307.


Cough-CPR, a deep rhythmic forceful cough repeated 30-60 times per minute, can be an effective resuscitative technique during emergencies occurring in the cardiac catheterization laboratory. We provide documented evidence on the potential of cough-CPR to maintain adequate systemic arterial blood pressure and consciousness during malignant ventricular arrhythmias, including the longest cough-CPR episode (75-90 sec), with continuous hemodynamics recorded. Results in three patients disclose that 1) mean arterial pressure during cough-CPR was 47-66% of nonarrhythmic baseline at a cough rate of 38-46% of normal sinus rhythm heart rate; 2) mean arterial pressure during hypotensive ventricular tachycardia was 17-60 mm Hg higher with than without cough-CPR; 3) at comparable diastolic pressures (33 vs. 31 mm Hg), systolic arterial pressure during cough-CPR was 40 mm Hg higher than basic CPR; and 4) consciousness can be maintained with cough-CPR during prolonged malignant ventricular arrhythmias. Thus cough-CPR can be a valuable adjunct in maintaining patient stability while definitive therapy for the malignant ventricular arrhythmia is administered.
