The study of lung functionalism is a matter which, without good reason, has been long forgotten. As for other organs rapidly charged functional study, characters of real importance for the lung, however, it just outlined. And this is how you could say with Roger, the physiology of the lung was in the same state as it was the physiology of the liver before work Claudio Bernard, no one would give importance to what, indeed, has law.

The pulse was one element that was first observed on trips to great heights. It has sought to establish a relationship between height and pulse rate while this was studied during the trip. At present - where effortless ascents or airplane - it is shown that such an event, but under certain conditions of rarefied air. We can say, as a result of our observations, this frequency is relatively moderate and only when signs appear normal Soroche to appear more or less intense tachycardia rhythm breaks.

In the previous communication we had necessarily refer to the performance of the heart against the effort to determine the frequency characteristics, shape, stability, etc., constituting man's pulse rate of the Andes. Indeed, we have noted the frequency of bradycardic and ortocárdicas reactions which are undoubtedly the best example of the physiological assessment of the Andean heart. So we said that the law of the Andean heart versus moderate or large effort, it is not a straight line as they occur at sea level - equal acceleration effort - but at the expense of the creek ortobradicárdicas reactions slowed to acceleration.
