We read with interest the recent article by Luks et al. (2017), which reports the relationship between arterial oxygen saturation and an echocardiographic index of pulmonary artery pressure (tricuspid transvalvular pressure gradient, TVPG) in healthy volunteers at sea level and after undertaking a two-week trek to Everest base camp.
