title: [The use of an inspiratory impedance valve during cardiopulmonary resuscitation does not improve long-term survival or neurologic outcome].
abstract: The impedance threshold device (ITD) works by increasing negative intrathoracic pressure, venous return and cardiac output during cardiopulmonary resuscitation. Although animal studies have shown promising results on haemodynamics, randomized studies and metaanalyses in humans have not shown better long-term survival or neurologic outcome. No studies have been done on the use of the ITD during in-hospital cardiac arrest. The ITD combined with active compression-decompression cardiopulmonary resuscitation may result in a better outcome.
