Distribution of Pulmonary Pulse Arrival in the Healthy Human Lung
No Thumbnail Available
The pulmonary artery pressure (PAP) can be noninvasively assessent using the EIT-derived pulmonary pulse arrival time (PAT). However, the spatial distribution of PAT is poorly understood. We analyzed the spatial distri- bution of PAT in healthy human lungs using cardiac-gated 3D EIT data. Results show PAT varies laterally (and is more than 20ms lower in the middle) but has little cradio-caudal variation.
