Low or high pulse rate can indicate heart problems. According to Dr. Fred Furgang in his article Hypoxia, Oxygen, and Pulse Oximetry, a pilot should use supplemental oxygen if the oximeter reading is below 90%, maintain at 91-92% level when doing remedial tasks and above 93% with increased workload.ow or high pulse rate can indicate heart problems.

Hereâs how to bring them back to life. First, some background. While the spill-proof batteries currently on the market are often referred to as gel batteries, most are AGM batteries-short for absorbed glass mat. Optima and Odyssey batteries are common examples. Unlike a gel battery, in which a silica agent is added to the electrolyte to form a semisolid, an AGM battery uses an ordinary sulfuric acid solution like any standard automotive battery (about 60/40 water and acid at full charge).
What Makes The Exide Edge Different? If you look at other AGM battery reviews you will find a lot of features that make them less reliable or less appealing than the Exide battery. One major difference is that the Exide battery price is substantially cheaper than other AGM marine battery types. Other batteries that claim to be quality marine batteries may not offer dual hookups for automobiles, they may not have the cold cranking amps, and they may not be fully spill proof.
