BACKGROUND This study was conducted to investigate the effect and mechanism of the nitrogen oxide 4-hydroxy- 2,2,6,6-tetramethylpiperidine (Tempol) on cerebral resuscitation caused by asphyxia-induced cardiac arrest. METHODS Airway occlusion-induced asphyxia at the end of expiration was used to establish the rat cerebral ischaemia-hypoxia injury model. A total of 90 adult male Sprague-Dawley ...
BACKGROUND AND PURPOSE Epinephrine administration during cardiopulmonary resuscitation increases cerebral blood flow by increasing arterial pressure. We tested whether potential beta-adrenergic effects of epinephrine directly influence cerebral blood flow and oxygen consumption independently of raising perfusion pressure. METHODS Four groups of seven anesthetized dogs were subjected to 8 minu...
BACKGROUND There are two competing theories of the mechanism of blood flow during cardiopulmonary resuscitation. The "cardiac pump" theory postulates that blood flows because the heart is squeezed between the sternum and the spine. The "thoracic pump" theory postulates that blood flows from the thorax because intrathoracic pressure exceeds extrathoracic vascular pressure and that flow is restri...
The cardiopulmonary resuscitation (CPR) persists as the best practice to maintain cerebral and coronary perfusion after cardiac arrest. Due to the chest compressions and ventilation maneuvers during resuscitation, there are common complications reported. Abdominal organs injuries occur in approximately 30% of patients, although studies show that they are under diagnosticated. The aim of this ar...
Does chest compression during cardiopulmonary resuscitation provide sufficient cerebral oxygenation?
