title: The effect of breath physiotherapeutic maneuvers on cerebral hemodynamics: a clinical trial.
abstract: OBJECTIVE
  To observe the repercussion of respiratory physiotherapy techniques on the mean arterial pressure (MBP), intracranial pressure (ICP), cerebral perfusion pressure (CPP), jugular venous oxygen pressure (PjvO2) and jugular venous oxygen saturation (SjvO2).
  
  
  METHODS
  The sample consisted of 20 patients with head trauma. The protocol consisted of physiotherapy techniques application of vibrocompression (VBC), expiratory flow increase (EFI) and suction.
  
  
  RESULTS
  The results show the maintenance on variables of cerebral hemodynamics during the techniques of VBC and EFI. However, in relation to suction, there was an increase of MBP, ICP, with maintenance of CPP, PjvO2 and SjvO2 and return to baseline of MBP and ICP 10 minutes after the end of suction.
  
  
  CONCLUSIONS
  The respiratory physiotherapy techniques (VBC, EFI) do not promote cerebral hemodynamic repercussion, unlike suction, in severe head injury patients, mechanically ventilated, sedated and paralyzed.
