Atmospheric Temperature and Pressure BIPS Body Temperature Pressure Saturated and STP Standard Temperature and Pressure Volume readings on Aestiva machines are displayed as ATP Many respiratory gas monitors display volumes as BTPS There can be as much as a 10 difference in these displayed values It does not indicate a failure of either device most likely the actual volume is somewhere between these two calculations Volume compensation is standard on 7900 and optional on 7100 models It is only applicable in Volume Control Ventilation A pressure differential transducer measures the pressure on each side of a Variable Flow Orifice Flow Sensor placed on the inspiratory side of the absorber This pressure differential equates to the velocity of the gas passing through the orifice This value is not displayed in the normal mode but can be viewed in service mode During volume ventilation the velocity of the gas passing through the inspiratory flow sensor is compared to the velocity of the gas coming from the flow valve If there is a difference the current to the flow valve will be modified to achieve the required output If the volume compensation option is active the first breath will be delivered based on flow valve calibration Information from the inspiratory flow sensor is then used to verify the flow and adjust it if needed The next delivered breath is adjusted by 50 of the difference between the set value and the value measure
