Kinetocardiogram, phonocardiogram, and arterial pulse waves during acute hemodynamic changes.
T HERE is currently a need for simple, atraumatic methods of assessing cardiovascular status. The kinetocardiogram (KCG) and external recordings of arterial pulse waves represent possible approaches which have not yet been adequately explored. Both techniques have been applied in various cardiovascular disorders, but little information has been obtained on the effects of acute alterations in he...
متن کاملSimplified method to measure respiratory-related changes in arterial pulse pressure in patients receiving mechanical ventilation.
STUDY OBJECTIVES Measuring respiratory-related changes in arterial pulse pressure is useful to guide fluid expansion in hemodynamically compromised patients. In the absence of automation, this can be uneasy in clinical practice. The objective of this study was to test an alternative approach (expiratory pause) that should be easier to apply. DESIGN Prospective observational study comparing tw...
متن کاملClinical use of respiratory changes in arterial pulse pressure to monitor the hemodynamic effects of PEEP.
In ventilated patients with acute lung injury (ALI) we investigated whether respiratory changes in arterial pulse pressure (DeltaPP) could be related to the effects of PEEP and fluid loading (FL) on cardiac index (CI). Measurements were performed before and after application of a PEEP (10 cm H2O) in 14 patients. When the PEEP-induced decrease in CI was > 10% (six patients), measurements were al...
متن کاملArterial pulse modulated activity is expressed in respiratory neural output.
Although it is well-established that sympathetic activity is modulated with respiration, it is unknown whether neural control of respiration is reciprocally influenced by cardiovascular function. Even though previous studies have suggested the existence of pulse modulation in respiratory neurons, they could not exclude the possibility that such cells were involved in cardiovascular rather than ...
متن کاملPulse oximetry and cardiorespiratory changes during upper gastrointestinal endoscopy in dogs
Objective- The objective of the present study was to determine the changes in heart rate, respiratory rate and arterial Oxygen saturation (SpO2) by administration of three drug combinations during upper gastrointestinal endoscopy. Design- Experimental study. Animals- 21 healthy and adults dog were randomly divided into three groups. Procedures- The IV combination of 6.5 mg/kg ketamine and 0....
