Growths on the surface of the eye can be unsightly and frightening. Most growths on the eye, which often occur as people age, pose no threat to health or vision and aren&rsquo;t cancers.
The unit of measure for static pressure is often inches of water (in. water). one inch of water is the suction needed to draw water up a straw one inch. pound per square inch static pressure (1 psi) is equal to 27.7 in. water static pressure. static pressure is given as Pascals (Pa).
All you have to do to see your CPAP pressure setting in terms of PSI is to enter your pressure setting in the text box below, and you'll see the corresponding pressure in PSI. For example, a CPAP machine pressure setting of 8 cm H 2 O is 0.11 PSI-a low pressure indeed.
