Descriptions of device types used in the pile-sorting activity.
| Device type | Device description | Example device | Features | Price |
|---|---|---|---|---|
| Non-automated | Non-automated devices include tools that support the manual counting of chest movements, by indicating when to start and stop counting. Currently produced by Moneray and procured by UNICEF | Acute Respiratory Infection (ARI) timer | Durable; low cost; long battery life; easy to use; requires little training | USD 4.82 |
| Assisted counting RR device | Devices that support an assisted count, by automating or negating the need for manual counting of each chest movement. Mobile software applications in the category of assisted count work when CHWs tap the screen or press buttons for each chest movement. Can run on feature phones or simple smartphones | RR smartphone app | Easy to use; fast result; doesn’t require counting skills; gives outcome | Free + cost of phone (approx. 70–150 USD) |
| Respirometer Feature phone app | Easy to use; fast result; doesn’t require counting skills; low cost; gives outcome | Free + cost of phone (approx. 20–50 USD) | ||
| Handheld pulse oximeter | Oximeters that were traditionally designed for professional rather than for home use. Many of them are suitable for adults, children and young infants, since oxygen is measured using a finger external sensor that can be purchased separately for paediatric and neonatal use | Lifebox | Rechargeable; long warranty life; robust; reusable probes | USD 250 |
| Mobile phone pulse oximeter | These devices function by connecting a pulse oximeter to a smartphone and then reading the oxygen saturation of the patient using an app installed on the phone with the oxygen values of the patient shown on the display of the phone. Requires a more advanced Android smartphone | Masimo iSpO2 | Anti-motion technology; neonatal probe; high-spec phone required | USD 150 + cost of phone (approx. 150–200 USD) |
| Finger-tip pulse oximeter | These affordable, easy-to-use pulse oximeter devices incorporate the probe and the device in one unit | Contec | Rechargeable batteries (charger provided) | USD 40 |
