    • Autoregulation of Cerebral Blood Flow During 3-h Continuous Cardiopulmonary Resuscitation at 27°C 

      Valkov, Sergei; Nilsen, Jan Harald; Mohyuddin, Rizwan; Schanche, Torstein Lindahl; Kondratyev, Timofey; Sieck, Gary C.; Tveita, Torkjel (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-09)
      Introduction: Victims of accidental hypothermia in hypothermic cardiac arrest (HCA) may survive with favorable neurologic outcome if early and continuous prehospital cardiopulmonary resuscitation (CPR) is started and continued during evacuation and transport. The efficacy of cerebral autoregulation during hypothermic CPR is largely unknown and is aim of the present experiment.<p> <p>Methods: ...

    • Rewarming With Closed Thoracic Lavage Following 3-h CPR at 27°C Failed to Reestablish a Perfusing Rhythm 

      Nivfors, Joar O.; Mohyuddin, Rizwan; Schanche, Torstein; Nilsen, Jan Harald; Valkov, Sergei; Kondratiev, Timofei V.; Sieck, Gary C.; Tveita, Torkjel (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-29)
      Introduction: Previously, we showed that the cardiopulmonary resuscitation (CPR) for hypothermic cardiac arrest (HCA) maintained cardiac output (CO) and mean arterial pressure (MAP) to the same reduced level during normothermia (38°C) vs. hypothermia (27°C). In addition, at 27°C, the CPR for 3-h provided global O2 delivery (DO2) to support aerobic metabolism. The present study investigated if rewarming ...

    • Study of the effects of 3 h of continuous cardiopulmonary resuscitation at 27°C on global oxygen transport and organ blood flow 

      Nilsen, Jan Harald; Valkov, Sergei; Mohyuddin, Rizwan; Schanche, Torstein Lindahl; Kondratiev, Timofei V.; Næsheim, Torvind; Sieck, Gary C.; Tveita, Torkjel (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-16)
      <i>Aims</i>: Complete restitution of neurologic function after 6 h of pre-hospital resuscitation and in-hospital rewarming has been reported in accidental hypothermia patients with cardiac arrest (CA). However, the level of restitution of circulatory function during long-lasting hypothermic cardiopulmonary resuscitation (CPR) remains largely unknown. We compared the effects of CPR in replacing ...
