Study summary

This study is to test the usability of a new pulse oximeter probe designed for children 0-5 years.

Read the detailed description

Pneumonia is the leading infectious cause of death in children under five. World Health Organization guidelines recommend measurement of peripheral oxygen saturation (SpO2) in children with pneumonia to guide treatment. This project focuses on the design of a new 'Lifebox' pulse oximeter probe for use in children 0-5 years of age.

A new oximeter probe compatible with the Lifebox oximeter has been designed to be used for children 0-5 years in all settings.

The aims of the study are to:

  1. to evaluate the usability of the redesigned Lifebox oximeter probe by an expert user
  2. to evaluate the usability of the redesigned oximeter probe by trained healthcare workers, against defined product specifications.
  3. to compare the usability of the redesigned oximeter probe to a market leading probe

What researchers measure

Primary outcomes

  1. Time to obtain SpO2 reading

    The time to obtain a stable reading will be declared by the healthcare worker or expert and noted by the independent observer, to give a proportion fulfilling the Target Product Profile (TPP).

    Time frame: Through completion of study, average one hour

Other outcomes

  1. Usability questionnaire

    Healthcare workers and the expert user will complete a usability questionnaire after completion of readings in children of different ages

    Time frame: Through study completion, average one hour
