Home-made spacers as effective as commercial spacers for bronchodilator therapy in children with acute asthma

A Cochrane review found no difference between commercial and home-made spacers in delivering bronchodilator: http://goo.gl/c7lVf

Home-made spacers for bronchodilator therapy in children with acute asthma were as effective as commercial spacers in a RCT published in the Lancet. A conventional spacer and sealed 500 mL plastic bottle produced similar bronchodilation in children with acute asthma:  http://bit.ly/VOXkj

Recently, I saw a blog post titled "Treating Asthma on the Cheap" which described a spacer device made out of a 500-ml water bottle. It sounds unlikely but this may work after all.

What is the best spacer? AeroChamber, toilet paper roll (?!), paper towel roll, rolled paper, plastic bottle spacer, bottle-holding chamber, nebulizer reservoir tubing? Paper towel roll was the best in this study: http://buff.ly/1jtRHCp

A recent letter claims that spacers should not be regarded as interchangeable: each pMDI–spacer combination should be treated as a unique system (ERJ, 2012).
