Application of impedance threshold devices during cardiopulmonary cerebral resuscitation

To review the use of impedance threshold devices (ITD) during CPCR, their proposed mechanism of action, and their application in veterinary medicine. Data sources include scientific reviews and original research publications using the PubMed search engine with the following keywords: 'impedance threshold device' and 'resuscitation' and the Veterinary Information Network search function using the keywords 'impedance threshold device.' Studies in human medicine have demonstrated that the use of an ITD during CPCR in patients during out-of-hospital cardiac arrest improves coronary perfusion pressure and cerebral perfusion pressure. This improvement in vital organ blood flow results in increased cardiac output and faster return of spontaneous circulation. The use of an ITD has been studied in people and currently holds a class IIb level of recommendation according to the 2010 American Heart Association Guidelines for CPR and Emergency Cardiovascular Care. This device is recommended as a way to improve hemodynamics during CPCR by enhancing venous return and avoiding hyperventilation, thereby increasing the likelihood of a successful resuscitation. Multiple controlled studies using pigs with ventricular fibrillation induced cardiopul...Continue Reading

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
