Just exactly what is a CPAP machine and what does CPAP mean ?.
Let us start with the name CPAP “CEE” “PAP” the name of the appliance is derived from a pressure of flow measurements expressed in CM H20 ( centimeteres of water ) all this measurement means is that a given pressure under flow will raise a column of water in a pipette of known diameter a certain height so if the pressure prescribed for the setting of your CPAP machine is say 8 CM H20 the pressure under flow will raise the column of water 8 centimetres.
