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).
Be aware of what youâre using to charge and maintain AGM batteries. Understand the purpose and specifications of whatever you use. My car is BMW X3 3000 and my battery Absorbent Glass Mat 12V 95Amps and as I use it not to often when I bought the battery they sold me a CLASS 2 BATTERY CHARGER MODEL LC-2152.
