![]() sure gagcs inserted into tho blood vcasels. They are also something more than lucre estimates, as this pressure has been measured by pres. The results vary in (iflorent experiments, but they arc sufficiently accurate to give us an average that wo may rely upon as within bounds. Others have estimated tho pressuro as that of u. The pressure per BfJiiaro inch was esthnmtoil by Poi- S4)uillc as four pounds three ounces. The pressure required at the mouth of the aorta to force the blood through the vessels of the human body, is estimated by Hales, as being equal per square inch of surface, to that exerted by a col umn of blood seven and one half feet high. For convenience, however, we shall consider it as being of the same weight as water, extreme accuracy not being essential to our purpose and in our computations we shall, for the most part and for the same reason, throw out fractions and use round numbers. Few would credit, at first, the statement that the hearts now beating in and around the city of New York, exert an aggregate power ample to propel a large steamer across the Atlantic ocean at a fair rate of speed, yet we shall be able to demonstrate that this is as much a fact, as that any of these steamers ever crossed that storm-torn sea.īlood is heavier than water its specific gravity being, ac cording to Booth, of from 1'0527 to 1'057. In the attempt to calculate the power of the human heart for a given time, we shall arrive at some curious and interesting, not to say astonishing results. It may, therefore, be brought within the domain of mathematics as well as any other machine. If we scrutinize the mechanism of the heart, we shall find that it involves in its operation nearly all the principles of hydrodynamics. Apply the gel on the electrode areas on the reverse side of the belt.That wonderful little pumping engine which we all carry around in our bosoms, and which runs without cessation till death ruthlessly closes the throttle, performs an amount of work so great as to be almost beyond belief till substantiated by arithmetical calculation. It ensures a better detection of the horse’s heart rate. To optimize the contact between the horse’s skin and the electrodes, contact gel can be used on the electrodes. Therefore, you can monitor your horse’s heart rate also when lungeing. The range of the heart rate sensor is over 10 m. View the horse’s heart rate on a compatible Polar training device or mobile app. The belt should stay under the girth/harness.
