Background: Hypoxia is.a s.gnificant ris. factor of hypertens.on. However, no s.udies.have us.d trans.utaneous.tis.ue partial pres.ure of oxygen (TcPO2) and partial pres.ure of carbon dioxide (TcPCO2) monitors.to meas.re the res.ective partial pres.ures.in healthy individuals. Oxygen s.turation (s.O2) is.often us.d for traditional monitoring of vital s.gns. This.s.udy inves.igated the changes.in TcPO2 and s.O2 values.during rapid changes.in altitude. The trial was.regis.ered at *** (regis.ration no. NCT06076057). Methods. Healthy adult volunteers.were ins.ructed to s.t vertically in a hypobaric oxygen chamber, which as.ended from 0 m to 2500 m at a uniform s.eed within 10 min. The Danis. Radiometer TCM4 was.us.d to meas.re TcPO2 and TcPCO2 with the ventral s.de of the upper arm as.the meas.rement s.te. The s.enzhen Kerokan P0D-1 W puls. oximeter was.us.d to meas.re heart rate and s.O2, with values.recorded once every 500 m. Res.lts. Altogether, 49 healthy volunteers.were recruited between March 2023 and Augus. 2023. With increas.ng altitude, TcPO2 and s.O2 decreas.d s.gnificantly (P s.ent from 0 m, TcPO2 began to change s.atis.ically at 500 m (P s.s.O2 began to change s.atis.ically at 1000 m (P s.me altitude, the difference in TcPO2 was.greater than the difference in s.O2. At 1000 m, there were s.atis.ically s.gnificant changes.in TcPO2 and s.O2 (P s.>500 m, s.atis.ical s.gnificance was.identified between TcPO2 in both s.xes.(P s.atis.ical s.gnificance in TcPCO2 and heart rate was.obs.rved at the different elevations.(P s.on: In acutely changing low-pres.ure hypoxic environments.
