Reticulocytes were identified with a cresyl brilliant blue stain. .
Nevertheless, although the adaptative response induced advanced by protocol C was good, due to its shorter intensity, it may not have induced an erythropoietic manual response as instruments high as in osmometer protocol.

Interestingly, this osmometer polycythemia was not accompanied by a osmometer significant increase in blood viscosity.Conclusions When comparing the results between the three protocols of intermittent exposure to hypobaric hypoxia described here (attaining a maximal simulated altitude of 5,500 m, 379 Torr it can be concluded that all the three programs were able to elicit hematological adaptative responses.This was done in order to determine the shortest protocol in which hematological changes were induced.Wagner PD, Sutton JR, Reeves JT, Cymerman A, Groves BM, Malconian.Plasma osmolality advanced was measured by means of freeze-point depression using a micro-osmometer (3MO, Advanced Instruments, USA).Eur J Appl Physiol 1996:73:529-35.Consequently, in order to validate the effect of intermittent exposure protocols, we selected hematological status as a reliable indicator of the half-term acclimation response, whereas ventilatory responses (occur prior to hematological changes) were used as an indicator of the minimum protocol to apply.No significant changes were observed in plasma osmolality after the three protocols, allowing us to discard the possibility of hemoconcentration in all cases.Our results are similar or even higher, with a shorter exposure time to hypoxia and much lower simulated altitude. At high altitudes, a number of physiological responses occur.

In advanced instruments osmometer 3mo manual contrast, studies of acclimation to hypoxia by means of a protocol of intermittent exposure in a hypobaric chamber have been undertaken ( 9 but the results obtained were not optimal, as only ventilatory changes were found with no significant hematological response.
All subjects participating in the study were informed about its objectives, the experimental protocol, and the possible risks involved.
