  • Multiple cylinders, concentrators and pulse oximeters could be included for each facility.

  • *Oxygen source function included assessment of cylinder regulator apparatus and measurement of concentrator gas concentration using an oxygen analyser.

  • †Pulse oximeter functionality included testing with Fluke simulator.

  • ‡Technician data from 27/28 facilities.

  • §Limited financial data on pulse oximeter or oxygen concentrator procurement costs (4/58, 7%), cylinder refill costs (7/58, 12%), cylinder cost data from a single SHF and PHC. US$1: 359 Naira. Maximum volume of a large oxygen cylinder is typically 3.4 or 7.0 m3 (G-type and H-type).

  • IQR, interquartile range, 25th–75th centiles; LGA, local government area; PHC, primary health centre; SHF, secondary healthcare facility; Spare parts, in stock or ordered in past 12 months.
