拋棄型噴霧器噴霧治療時是否需要輕拍藥杯?A pilot study
Should we need to tap or not the small volume Nebulizer to minimize dead volume? A pilot study
摘要
Background: The aerosol medication therapy was usually applied with small volume nebulizers (SVN), but rare people understand to tap sides of nebulizer to minimize dead volume is very important. So I compared the dead volume of the nebulizer between before and after the practitioner to tap. Method: Thirty disposable jet nebulizer divide to five models with three manufacturers were tested. The jet flow was set in 6 L/mim and keep the SVN upright 90 degree angle. Each SVN was weighted by Ohaus analytical plus electronic balances models AP250D8 Before and after place 3 ml of normal saline in nebulizer after absent the aerosol particles and continuous to tap the SVN. The data was analyzed with the descriptive statistics, variance and T test Result: The mean net weight of 30 SVN is 17.62 gm (13.99 gm - 20.70 gm). The mean dead volume of the SVN before tap the side of SVN is 1.26 ml (0.12 - 1.88 ml), that means over 42% of total volume were waste and the patient only get 58% (mean = 1.74 gm, 2.87~1.13 gm ). But after we tap the side of SVN behind the particle disappear that the patient can get the total aerosol volume up to 82% (mean 2.47 gm, 2.9~2.04gm) P ＜ 0.001 by compare T-test. Conclusion: The result supports that to tap the side of SVN during nebulization can minimize the dead volume of small volume nebulizer that make the patients get more medication.
