When a lay person with no CPR training is on the phone with 911 and the dispatcher is giving instructions to the lay rescuer
When the rescuer is unwilling or unable to do the ventilations."The Canadian Red Cross recognizes that compression-only CPR is an acceptable alternative for those who are unwilling, unable, untrained, or are no longer able to perform full CPR. In some cases, compression-only CPR is the preferred method for members of the public who witness an adult suddenly collapse. The issue has recently emerged based on research published in the journal Circulation."
100 But you should only do 30 before pausing to give 2 breaths (unless your teaching is different, as it varies country, to country)
The lack of compression in one cylinder of a Chevy 355 engine could be caused by a number of issues such as a leaking valve, a blown head gasket, a cracked piston, or improper sealing of the piston rings. It is recommended to perform a compression test and further diagnostic tests to identify the exact cause of the low compression in that cylinder.
Blasters are 2u strokes which means unlike the four stroke they only have the power and exhaust stroke. They dont need the intake stroke because the gas is already mixed in with the oil (yama-lube recommended) . Now u might notice a blaster doesent have a compression stroke. This is because the motors gain compression by not having a timing chain between the crank and the cam (because ther are no valves). This means there is no where for compression to escape thus giving u
Pict files can use 2 different forms of compression. 1- RLE Compression (the default) is lossless. 2- JPEG compression (only on some systems/graphics programmes) is lossy.
Studies have found that compression only is more effective, so 1 compression to zero ventilations is the correct ratio. If the person's heart is beating, then you can worry about respiration. If not, keep the blood circulating and let respiration worry about itself (there will be some gas exchange in the lungs even without it, and if you're compressing a person's chest, you're going to be compressing their lungs somewhat anyway, and even without both of those factors, there's quite a bit of dissolved oxygen in the blood; the really critical thing is to make sure that the brain ... which uses it pretty quickly ... doesn't use up the local supply and start to die off).

Amazon is one retailer that has a selection of compression test kits for sale, and you can also find them on the eBay website. these are the only places that seem to sell these.
Australia is the only country on the continent of Australia.
Low compression will not cause an engine to not run. It may not run efficiently but it will run. Low compression on all cylinders is caused by wear, and can only be fixed by overhauling the engine. Low compression on just one cylinder can be a blown head gasket, burnt valve, or a broken ring on that cylinder. I also depends on what you mean by "below average". An engine with lots of miles may very well have a compression reading that is below the factory specifications and not be cause for alarm. It depends on how much below specs that compression is. In any case, the only fix is to open the engine up.
Is the only state that does not have country?"
The premise of the question is incorrect, so "why" is irrelevant. You appear to be making a novel distinction between "vapors" and "gases" that I have never heard before.
