Nitrous oxide saturation, effect

The behavior of nitrous oxide during irradiation seems quite unusual. Whereas, as an irradiation atmosphere, 18 types of well-known inorganic gases and 4 types of saturated hydrocarbon gases were tested previously, the species which evidently showed such a singular effect were limited to nitrous oxide and xenon. In the work reported here, three types of polymers having different types of molecular structure were examined, but examination showed many points of similarity in the behavior of nitrous oxide. 

The next experiments consisted of irradiating the unbleached TMP pulp suspension in the presence of 1% hydrogen peroxide or 0,3% sodium borohydride. This was done to measure the influence of an oxidizing and a reducing chemical co-irradiated with the pulp suspension. Also, H202 is known to react with e solv to produce OH (equation 8). The effect of saturated nitrous oxide in pulp suspension was also studied. In presence of yrays, N20 is known to react with e-solv to generate OH. The experimental results are shown in Figure 5. 

Knight and Sutton (see section 5.12) in their study of y-ray irradiation of saturated solutions of nitric oxide examined the effect of adding nitrous oxide to the solution. From the results obtained in these experiments they were able to estimate the ratio 152/ 154 = 2.5+0.2, where ki64 refers to... 

Respiratory System Nitrous oxide causes modest increases in respiratory rate and decreases in tidal volume in spontaneously breathing patients. The net effect is that minute ventilation is not significantly changed and remains normal. Even modest concentrations of N O markedly depress the ventilatory response to hypoxia. Thus, it is prudent to monitor arterial saturation directly in patients receiving or recovering from nitrous oxide.
