Non-invasive detection of hypovolemia or fluid responsiveness in spontaneously breathing subjects
BACKGROUND In the assessment of hypovolemia the value of functional hemodynamic monitoring during spontaneous breathing is debated. The aim of our study was to investigate in spontaneously breathing subjects the changes in hemodynamic parameters during graded central hypovolemia and to test whether slow patterned breathing improved the discriminative value of stroke volume (SV), pulse pressure ...
متن کاملAssistance to Ventilation in Spontaneously Breathing Subjects
In five supine normal subjects breathing spontaneously, we studied the effects of high-frequency chest wall oscillation (HFCWO), which was achieved by oscillating the pressure in an air-filled cuff wrapped around the lower thorax. Oscillations of 3.5 and 8 Hz (in randomized order) were applied for 15 minutes each at both maximal (mean of 90 to 102cm H,O) and half-maximal peak tolerable cuff pre...
متن کاملAssessment of fluid responsiveness in spontaneously breathing patients: a systematic review of literature
Patients who increase stoke volume or cardiac index more than 10 or 15% after a fluid challenge are usually considered fluid responders. Assessment of fluid responsiveness prior to volume expansion is critical to avoid fluid overload, which has been associated with poor outcomes. Maneuvers to assess fluid responsiveness are well established in mechanically ventilated patients; however, few stud...
متن کاملVariability of aortic blood flow predicts fluid responsiveness in spontaneously breathing healthy volunteers.
BACKGROUND Assessment of fluid responsiveness is an important topic in acute cardiology. Echocardiographic measurement of respiratory variations of aortic blood velocity in ventilated shock patients can accurately predict the effect of volume expansion. On the other hand, it remains unclear whether this respiratory variability is a common physiological reaction to hypovolaemia and whether its m...
متن کاملDoes inferior vena cava respiratory variability predict fluid responsiveness in spontaneously breathing patients?
INTRODUCTION We have almost no information concerning the value of inferior vena cava (IVC) respiratory variations in spontaneously breathing ICU patients (SBP) to predict fluid responsiveness. METHODS SBP with clinical fluid need were included prospectively in the study. Echocardiography and Doppler ultrasound were used to record the aortic velocity-time integral (VTI), stroke volume (SV), c...
