High altitude arterialised capillary earlobe blood gas measurement using the Abbott i-STAT

Abstract: Daily earlobe blood gas analysis using the Abbott i-STAT is feasible in a protected environment at high altitude. Participants and equipment should be kept warm before and during testing. Spare cartridges should be available. This methodology may be useful for both research and therapeutic measurements in remote, rural and wilderness medicine.

“…In remote areas that lack the resources for drawing blood from the radial or femoral artery or a blood gas analyzer, the collection of arterialized earlobe blood and use of simple portable instrument such as Abbott i-stat, can also be considered, which have certain application value according to the literature (1,14). This study has some limitations.…”

“…Venous blood samples were taken daily, centrifuged, and the sera were stored alongside urine samples. Daily arterialized ear lobe partial pressure of oxygen (pO 2 ) measurements were obtained using an Abbott i-STAT (Lewis et al, 2018 ), and twice daily Lake Louise (LL) AMS scores were recorded.…”

“…Blood gas monitoring was performed with earlobe arterialized capillary blood and analyzed using the I‐STAT ® System (Abbott Laboratories). The method of capillary sampling has been described previously 7 : The inferior aspect of the earlobe was cleaned with an alcohol solution and dried in the air. Nicotinate paste was applied to the earlobe for at least 10 min to induce capillary vasodilation.…”
