Least-squares estimates for coefficients of linear models that predict tidal volume (VT) via respiratory inductive plethysmography (RIP) are given. The qualitative diagnostic calibration sum formula M(RC + KAbd) arises for idealized thoracoabdominal

Bootstrap resampling provides a versatile and reliable statistical method for estimating the accuracy of quantities which are calculated from experimental data. It is an empirically based method, in which large numbers of simulated datasets are gener

The traditional method of derivation of phase difference between ribcage and abdomen breathing movements from a Lissajous plot is shown to be unsatisfactory for assessing the degree of asynchrony. The signal processing technique of cross-correlation

Induced hypotension is commonly used during surgery to decrease arterial pressure. Sodium nitroprusside and isoflurane are well-known hypotensive agents. The use of self-tuning adaptive control of induced hypotension was assessed with the use of sodi

Doses from intravenous intakes of 59 Fe or 57 Co chloride during pregnancy were estimated. Near term fetal organ doses were derived via the MIRDOSE3 newborn phantom, with mean dose/cumulated activity (S) values rescaled for compatibility with near te

A gamma fit facilitates smoothing and extrapolation of distorted tracer-dilution curves in blood flow studies. Theoretically based empirical estimators were developed as simple alternatives to direct regression approaches from simulated gamma distrib

Absorbed radiation doses to internal foetal organs were calculated according to the medical internal radiation dose (MIRD) technique in this study. Anthropomorphic phantoms of the pregnant female as in MIRDOSE3 enabled estimation of absorbed dose to

The theory for optimal linear combination of uncalibrated breathing movements was developed and applied in non-invasive respiratory monitoring situations for assessment. 16 patients were monitored overnight for respiratory depression during postopera

The general theory of indicator-dilution methods provides a basis for computing improved cardiac output estimates. Interpretation is via indicator-dispersion modeling with Brownian motion of drifting particles. Detected curves indicate the distributi
