Background
Every year an average of 0.1% of US and UK populations is mechanically ventilated in ICU[1]. Lung ventilators are manufactured by more than 50 different companies, each of them use their own terminology. The use of different terminology and the complexity of the design can lead to user errors, which may result in patients injuries[3]. The International Organization for Standardization is proposing ISO 19223[2] to improve the ease of use and patient safety through the standardization of the lung ventilator terminology.
Objective How to assess the impact of the terminology proposed in ISO 19223?
Method The research has been structured in the following steps 1) literature review of usability tests used to assess the use of different terminologies on medical devices, 2) identify the types of instrument to use in the pilot study, 3) identify the appropriate platform to develop the lung ventilator mock-up which shall be used in the pilot study.
Results
Conclusions The proposed set of usability tests will help to assess the impact of the vocabulary proposed in ISO 19223.

A survey will be use to capture the association between a term and its abbreviations. The talk aloud will help to gain more information regarding specific behaviors observed from the participants.
