Chinese Journal of Practical Nursing 2015;31(34):2583-2585
Objective To investigate the effect of high altitude aviation on the pressure and diameter of the trachea cannula cuff after injecting air or water. Methods In the circumstance 5 km height and 795 hPa cabin pressure, the air injected cuffs were divided into two groups, one was under the ground circumstance, the other was in the high altitude aviation environment. The volumes of injected air were 5 ml, 7 ml, 9 ml, 11 ml, 13 ml, 15 ml, 17 ml, and the cuff pressure and its diameter were measured. The water injected cuffs were also divided into two groups of ground and high altitude aviation environment. The volumes of injected water were 10 ml, 12 ml, 14 ml, 15 ml, 16 ml, and the cuff pressure and its diameter were measured. The results were compared between the ground circumstance and high altitude aviation environment. Results The diameter of injection air group versus under the ground circumstance group had the statistical significance (t=5.000-9.449, P<0.05), when the injection air was larger than 15 ml, the pressure effect had statistical significance (t=5.000, 8.000, P<0.05). Water injection group had not statistically significant. Different water volume injection had no effect on pressure and diameter (P>0.05), while different air volume injection had significant effect on pressure and diameter (F=5.132, 5.980, P<0.01). When the water volume was 10 ml, the cuff pressure was (24.00±4.62) cmH2O (1 cmH2O=0.098 kPa) , which was appropriate to the range of cuff pressure (20-30 cmH2O). Conclusions In high altitude aviation environment the trachea cannula cuff should adopt water injection, and the best water volume is about 10 ml.
