AB  - BACKGROUND: Workers coming from lowland regions are at risk of developing acute 
      mountain sickness (AMS) when working in low oxygen high-altitude areas. 
      OBJECTIVES: The aim of this study was to improve the conditions that lead to 
      hypoxia and ensure the safety of the high-altitude workers. We analyzed the 
      influence of low atmospheric pressure on the oxygen enrichment process in 
      high-altitude areas using an engineering method called low-pressure swing 
      adsorption (LPSA). METHODS: Fourteen male subjects were screened and divided into 
      three groups by type of oxygen supply system used: (1) oxygen cylinder group; (2) 
      LPSA oxygen dispersal group; and (3) control group. These tests included arterial 
      oxygen saturation (SaO2), pulse rate (PR), breaths per minute (BPM), and blood 
      pressure (BP). RESULTS: The results showed that after supplying oxygen using the 
      LPSA method at the tunnel face, the SaO2 of workers increased; the incidence of 
      acute mountain sickness, PR, and BPM significantly decreased. CONCLUSIONS: The 
      LPSA life support system was found to be a simple, convenient, efficient, 
      reliable, and applicable approach to ensure proper working conditions at 
      construction sites in high-altitude areas.
