EIT measurements and static prediction of lung volume

Proceedings of the Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 1992
This paper discusses the possibility to compute static estimates of electrical conductivity of the lungs from EIT measurements by using the Boundary Element Method as an accurate three-dimensional solution technique to the forward problem. A relation is set up between these estimates and lung volume, without needing EIT images.

Measurement of lung fluid volumes and albumin exclusion in sheep

Journal of Applied Physiology, 1989
A radioactive tracer technique was used to determine interstitial diethylenetriaminepentaacetic acid (DTPA) and albumin distribution volume in sheep lungs. 125I- and/or 131I-labeled albumin were injected intravenously and allowed to equilibrate for 24 h. 99mTc-labeled DTPA and 51Cr-labeled erythrocytes were injected and allowed to equilibrate (2 h and

Measurement of high lung volumes by nitrogen washout method

Journal of Applied Physiology, 1994
Studies on human infants suggested that thoracic gas volume (TGV) measured at end exhalation may not depict the true TGV and may differ from TGV measured from a series of higher lung volumes and corrected for the volume added. This was explained by gas trapping.

Use of an acoustic helium analyzer for measuring lung volumes

Journal of Applied Physiology, 1981
We have evaluated the use of an acoustic gas analyzer (AGA) for the measurement of total lung capacity (TLC) by single-breath helium dilution. The AGA has a rapid response time (0-90% response = 160 ms for 10% He), is linear for helium concentration of 0.1-10%, is stable over a wide range of ambient temperatures, and is small and portable.

Influence of Lung Volume History on Closing Volume Measurement During Anaesthesia

Acta Anaesthesiologica Scandinavica, 1978
Airway closure measurements were made with the bolus technique on eight healthy subjects, who were in a supine position prior to and during anaesthesia. Measurements were made on an expiration following vital capacity (VC) and 30% VC. Closing volume (CV) was calculated prior to anaesthesia, and closing capacity (CC)—functional residual capacity (FRC ...

Noninvasive measurement of regional interstitial lung volume in sheep

Journal of Applied Physiology, 1988
The noninvasive external radioflux detection method (ERD) measures net transvascular flux of tracer protein into and out of the lung extravascular compartment (EV) and time to zero flux between compartments. With this information we can now estimate regional interstitial volume in the field of the external probe (VIs).
