Respirophasic carotid artery peak velocity variation as a predictor of fluid responsiveness in mechanically ventilated patients with coronary artery disease.
BACKGROUND We studied respirophasic variation in carotid artery blood flow peak velocity (ΔVpeak-CA) measured by pulsed wave Doppler ultrasound as a predictor of fluid responsiveness in mechanically ventilated patients with coronary artery disease. METHODS Forty patients undergoing elective coronary artery bypass surgery were enrolled. Subjects were classified as responders if stroke volume i...
متن کاملBreathing cardiovascular variability and baroreflex in mechanically ventilated patients.
Heart rate and blood pressure variations during spontaneous ventilation are related to the negative airway pressure during inspiration. Inspiratory airway pressure is positive during mechanical ventilation, suggesting that reversal of the normal baroreflex-mediated pattern of variability may occur. We investigated heart rate and blood pressure variability and baroreflex sensitivity in 17 mechan...
متن کاملBronchoscopy in Mechanically Ventilated Patients
The origins of bronchoscopy date back to 1897 when Gustav Killian, considered “the father of bronchoscopy”, performed the first airway examination with a rigid esophagoscope to a farmer extracting a piece of bone that had lodged in the main stem bronchus. Shigeto Ikeda in 1964 revolutionized the field of bronchoscopy with the introduction of a flexible instrument that could be introduced to sub...
متن کاملAge-related decrease in inferior vena cava diameter measured with echocardiography.
The diameter of the inferior vena cava (IVC) measured with echocardiography is clinically used as a parameter to estimate right atrial pressure, which reflects dehydration or overhydration. Because elderly patients fall easily into dehydration, normal values for IVC diameters in elderly patients may be helpful for geriatric medicine. However, normal values of IVC diameter in relation to age hav...
