What's the difference between isobaric and isopiestic?
Isobaric
Definition:
(a.) Denoting equal pressure; as, an isobaric line; specifically, of or pertaining to isobars.
Example Sentences:
(1) The mean spread of sensory blockade with isobaric bupivacaine was 16.95 segments (T6).
(2) Model predictions based upon these data compare favorably with published reports of isobaric inert gas supersaturation, as well as several previously unpublished observations.
(3) The appearance of isobaric HPNS during the switch might be due to the disappearance of the narcotic substance which suppressed or masked the clinical symptoms; it might also be due to the sudden increase in the partial pressure of He, which was equivalent to a fast compression.
(4) These results suggest that pre-existing hypertension can be recognized as an important factor to explain blood pressures changes during isobaric bupivacaine spinal anesthesia in elderly patients.
(5) This paper is concerned with the theretical background and implications of isobaric supersaturation and bubble formation in the microcirculation following an abrupt shift from one inspired inert gas to another.
(6) We suggest the results can be explained on the basis of the time-varying elastance concept: systolic elastance is the same for isovolumic and isobaric beats but depends on contractility.
(7) The decrease in mean arterial pressure was significantly more severe in the hyperbaric (30%) than in either the isobaric (18%) or hypobaric (14%) groups.
(8) These ions, which are referred to as (B-16) ions, permit differentiation between the isobaric amino acids lysine and glutamine in peptide mass spectra.
(9) The upper margin of analgesic zone at 15min and 60min after the subarachnoid injection of bupivacaine was higher in the hyperbaric groups, but it receded thereafter and significant differences were found at 120min compared with the isobaric group.
(10) Sixteen animal exposures (8 dives, 2 animals per dive) to a sudden isobaric gas switch from saturation on N2 to He were conducted; 8 saturations occurred at 132 fsw and 8 at 198 fsw.
(11) Group 1 patients received 3 ml of 0.5% isobaric bupivacaine.
(12) The duration of analgesia and the cardiovascular changes during anesthesia of spinal blockade with isobaric bupivacaine were examined in 36 patients between 21 and 75 years old undergoing percutaneous nephro-ureterolithotomy.
(13) In addition 3 ml isobaric bupivacaine in doses of 7.5 mg (0.25%), 15 mg (0.5%) and 22.5 mg (0.75%).
(14) These further signals may be useful in differentiating peptides containing lysine from those containing the isobaric glutamine.
(15) Individual diameter- and compliance-pressure curves extrapolated from the measured diameter and mean pressure point with a logarithmic elastic model permitted calculation of isobaric diameter and compliance at the same pressure in each subject.
(16) At isobaric intervals, compliance did not differ between control and myopathic ventricles.
(17) Because of the absence of a defined zone of analgesia, the small volumes required and the "ready for use" preparation, intrathecal isobaric morphine therapy will lead to easy self-administration via an implanted pump in the future.
(18) However, by measuring arterial compliance at the same pressure, its isobaric values were found to be unchanged.
(19) The 9 former premature received 0.6 ml isobaric bupivacaine 0.5%, and the child born on term with diaphragmatic hernia 0.8 ml isobaric bupivacaine 0.5%.
(20) Overall, measured isobaric diameters and measured compliance correlated with systolic, diastolic, and mean blood pressure values (p less than 0.001), whereas isobaric compliance correlated only with systolic (p less than 0.05) and pulse (p less than 0.01) pressure values.
Isopiestic
Definition:
(a.) Having equal pressure.
Example Sentences:
(1) Spectrophotometry, (micro)cryoscopy and the isopiestic method are presented in more detail.
(2) Good agreement is obtained with results provided by the isopiestic and NMR techniques.
(3) Samples hydrated slowly by isopiestic equilibration exhibited more exchange than was observed for samples of the same water content that had been hydrated rapidly by solvent addition.
(4) Isopiestic vapor pressure measurements have been used to obtain free energies of transfer of ribonuclease A from dilute buffer to solutions of either urea or guanidine hydrochloride (GdnHCl) over a wide cosolute concentration range.
(5) Powder samples were hydrated either by isopiestic equilibration, with a half-time for hydration of about 1 h, or by addition of solvent to rapidly reach final hydration.
(6) Isopiestic equilibration measurements were made on ten protein-denaturant systems involving polyglycine, egg albumin, collagen, horse heart myoglobin, and the denaturants urea, 1,3-dimethylurea, 1,1-dimethylurea, and thiourea.
(7) Such effects would be expected to contribute more strongly during the isopiestic equilibration process.
