The flow rate of reactant gas (O2) and carrier gas (Ar), duration of growth time, growth temperature, and pressure were carefully set and monitored since slightest change in these parameters may affect the result of the samples obtained.
With gasoline addition, the gas injection duration is decreased, thus reducing the fuel entering limitation.
Arterial blood gas, ARDS duration before ECMO, ventilator settings included tidal volume, respiratory rate, PEEP, peak inspiratory pressure, dynamic driving pressure (the difference between peak inspiratory pressure and PEEP) and FiO2 were recorded before ECMO initiation.
A study in a murine tumour model showed that the level of radiosensitisation achieved is dependent on both the CO2 content of the inspired gas and the duration of gas breathing (Hill et al, 1998).
The slices were exposed to 1.5% isoflurane or fresh gas for durations of 1, 3, or 5 h.
A portable gas analyser (Cosmed K4, Rome, Italy) complete with a face mask was used to measure expired gases throughout the duration of the testing.
The K4 Cosmed Breath analyzer (Cosmed K4, Italy), with a junior face mask, head net and harness, was used in order to measure breath by breath expired gases throughout the duration of the testing.
Simple regression analysis was performed to investigate the correlation between (1) the percentage change in PaO2/FiO2 and respiratory mechanics, (2) the percentage change in PaCO2 and respiratory mechanics, and (3) the percentage changes in respiratory mechanics and blood gases and the duration of the surgical procedure.
It should be noted that, before the experiments, the BBM medium was first purged with nitrogen gas for a duration of 3 min to remove the dissolved gases and ensure that the initial dissolved CO2 concentration is zero.
The cladding creep determines in part the width of the gas gap, the duration to pellet-cladding contact and the stresses to the cladding due to the pellet expansion.
