What's the difference between barometric and isobarometric?
Barometric
Definition:
(a.) Alt. of Barometrical
Example Sentences:
(1) Gradual seasonal changes in climatic factors, such as temperature, humidity, visibility, and barometric pressure, seem to have no appreciable effect on the Schirmer test No.
(2) With increasing altitude PEF as measured by the spirometer increased linearly with decreasing pressure, so that at a barometric pressure of 380 mm Hg* (half an atmosphere, corresponding to an altitude of 5455 m) there was a 20% increase over sea level values.
(3) Enzymatic activities were determined in the prosencephalon of rats which had been exposed repeatedly for 8 hrs, either from the age of 1 to 17 days or in adulthood, to an altitude of 7,000 m in a barometric chamber (up to a total of 104 hrs).
(4) Environmental factors such as humidity and temperature variation are shown to have acceptably small effects on both short- and long-term exposure data; barometric pressure affects the data in a predictable manner.
(5) In practice, this should mean that the risk of structural damage will be increased by any process which reduces the compliance of one or both of the cochlear windows, for example, extremes of middle ear pressure perhaps brought about by Eustachian tube dysfunction or rapid barometric pressure changes.
(6) Breathing pattern in response to maximal exercise was examined in four subjects during a 7-day acclimatisation to a simulated altitude of 4247 m (barometric pressure, PB = 59.5 kPa).
(7) By comparing the frequency of bleeding in hemophiliacs with meteorological phenomena, and by the one year material revision of the Hematology Department of the Institute for Child Care in Novi Sad (Yugoslavia) as well as the simultaneous recording of barometric pressure, it was found that the increase of atmospheric pressure was strongly associated with spontaneous bleedings in hemophiliacs.
(8) We describe an operating table in which the whole patient, apart from the eye undergoing surgery, is enclosed in a caisson within which the barometric pressure can be lowered at any time during surgery.
(9) Several medical problems may occur because of rapid changes in barometric pressure, including barotitis media, which is best treated in flight.
(10) In newborn awake kittens within the first week after birth we measured VE by the barometric method, oxygen consumption (VO2) and CO2 production (VCO2) by manometric techniques during air breathing and after 10 min of 10% O2 breathing.
(11) Climatic data (barometric pressure, rainfall, humidity, and wind strength and direction) were obtained and compared with frequency of exacerbations of asthma.
(12) To examine the role of barometric pressure in high-altitude pulmonary edema, we randomly exposed five unanesthetized chronically instrumented sheep with lung lymph fistulas in a decompression chamber to each of three separate conditions: hypobaric hypoxia, normobaric hypoxia, and normoxic hypobaria.
(13) Three factors influenced predictive accuracy: 1) a primary diagnosis of congenital diaphragmatic hernia (CDH) was associated with a greater mortality (P less than 0.001) and a significantly higher positive predictive value (PPV) for all criteria (P = 0.0009-0.012) than that seen in patients with other primary diagnoses; 2) calculating the alveolar-arterial oxygen gradient using an assumed, rather than measured barometric pressure, or estimating oxygenation index using a calculated, rather than a measured, mean airway pressure, increased false positive mortality predictions in non-CDH patients; and 3) requiring a peak inspiratory pressure (PIP) of at least 50 cm H2O in the definition of maximal medical management, rather than a PIP of 20-49 cm H2O, significantly increased the PPV for three of four criteria examined (P = 0.02-0.04).
(14) There was no significant difference between days with and without croup admissions, with respect to barometric pressure or relative humidity.
(15) Bert showed that functional impairment or death occurred in each of a variety of species at a certain inspired oxygen pressure regardless of what combination of barometric pressure and oxygen percentage was used to achieve it.
(16) Ventilation of rats was measured using the barometric method before and after hyperbaric O2 (HBO) exposure, at either air, 80% O2, or 4% O2.
(17) By use of a barometric technique, tidal volume (VT), minute volume (VE), respiratory frequency (f), and respiratory evaporative heat loss (Eex) were measured from conscious unrestrained potoroos (Potorous tridactylus), barred bandicoots (Perameles gunnii), and New Zealand white rabbits (Oryctolagus cuniculus) at temperatures in and above the thermoneutral zone (TNZ).
(18) Everest (8,840 m, barometric pressure of 240 Torr, inspiratory O2 pressure of 43 Torr).
(19) The effect of PGF2 alpha has been evaluated in 11 unanaesthetized unrestrained piglets and in 3 anaesthetized piglets (2-3 days old) using a barometric-plethysmographic technique.
(20) Controls were pair-fed rats maintained at ambient barometric pressure and studied at PIO2 68-70 Torr for 4 h (acute hypoxia) or at ambient PIO2 (normoxia).
