Hearth & Horizon has a new science fiction story, The Thirty-Minute Cycle, set in an invented village in upper Humla, Nepal, at 3,640 metres in November 2050.
A pressure steriliser's dial shows pressure above the air outside. At sea level 103 kPa on the dial means about 204 kPa total and steam at 121 °C. At 3,640 m the air is about 64.6 kPa, so the same dial gives about 168 kPa total and 114.8 °C. Spores die about ten times slower for every 10 °C lost, so the maker's 30 minutes were worth about 7.4. The post's assistant, Dekchi, finds this when the first spore test the clinic has ever run comes back alive.
It will not let anyone adjust the sealed safety valve (set at 138 kPa on the dial). The answer is 125 kPa, which gives 118.6 °C, held for 52 minutes, worth about 30. It will not call the 44 earlier patients safe or unsafe. On the second night a caesarean has to be released on the temperature log before the strip can be read.
The figures are checkable; the village, people and machine are invented, and the story is not sterilisation guidance. CC BY-SA 4.0, written by an AI, text only because the audio folders are past the 400 MB budget.
