Ventilation inhomogeneity in patients with cystic fibrosis measured by electrical impedance tomography
Objective: The distribution of ventilation within the lung is inhomogeneous. We hypothesized that the degree of inhomogeneity in patients with cystic fibrosis (CF) differs from that in healthy subjects. Method: Three adult patients with cystic fibrosis (CF) and two healthy subjects were recruited for this preliminary study. Subjects were asked to breathe in as deep and exhale as hard as possibl...
متن کاملHyperoxia affects the regional pulmonary ventilation/perfusion ratio: an electrical impedance tomography study.
BACKGROUND The way in which hyperoxia affects pulmonary ventilation and perfusion is not fully understood. We investigated how an increase in oxygen partial pressure in healthy young volunteers affects pulmonary ventilation and perfusion measured by thoracic electrical impedance tomography (EIT). METHODS Twelve semi-supine healthy male volunteers aged 21-36 years were studied while breathing ...
متن کاملRegional ventilation by electrical impedance tomography: a comparison with ventilation scintigraphy in pigs.
STUDY OBJECTIVE The validation of electrical impedance tomography (EIT) for measuring regional ventilation distribution by comparing it with single photon emission CT (SPECT) scanning. DESIGN Randomized, prospective animal study. SETTINGS Animal laboratories and nuclear medicine laboratories at a university hospital. PARTICIPANTS Twelve anesthetized and mechanically ventilated pigs. INT...
متن کاملPulmonary ventilation and perfusion assessed by electrical impedance tomography Experimental studies in pigs
Pulmonary ventilation and perfusion and ventilation/perfusion (V/Q) matching determine gas exchange in every lung unit in the healthy state and in the pathologically altered lung. Mismatch of V and Q lead to hypoxaemia and hypercapnia and monitoring of V/Q relations are thus important in critical illness. This thesis focuses on electrical impedance tomography (EIT) to monitor pulmonary perfusio...
متن کاملAssessment of regional ventilation in acute respiratory distress syndrome by electrical impedance tomography.
Mechanical ventilation in acute respiratory distress syndrome (ARDS) incurs a risk of ventilator-associated lung injury (VALI) from inhomogeneous conditions and different properties of dependent and non-dependent lung regions at risk of atelectasis and overdistension, respectively. Electrical impedance tomography (EIT) offers regional ventilation assessment to optimise treatment with mechanical...
