Working over 5,000 m: medical check-up

Any work activity performed at elevations over 3,000 m above sea level is considered as work at high altitude. The changing environmental conditions result in an adaptation of the human organism, mainly due to a reduced partial pressure of oxygen in the air and a proportional decrease in barometric pressure. We carried out a systematic review of the scientific literature in this field so as to develop a health and risk protocol as well as a procedure of ascent for researchers and staff expected to work in a science research lab at an altitude of 5,100 m asl. We wish to highlight the crucial role that occupational medicine plays in the formulation of a medical protocol used to assess the suitability of staff to work in environments posing high risks to human health, as in this case, and of a protocol of ascent minimizing the risk associated with changes in altitude.
