CALIBRATION SYRINGE PLUS DLCO BAG AND THE VARIABLE

CALIBRATION SYRINGE PLUS, DLCO BAG AND THE VARIABLE CUFF PRESSURE ADAPTER An Animated Version of Use

Using the CALIBRATION SYRINGE PLUS to perform the Nitrogen Wash out Test The Calibration Syringe Plus measures every test done in a complete P. F. T. Filled with 79% Nitrogen/21% Oxygen FRC 100% Oxygen up Down VT Communicat ion Tube Nitrogen Analyzer Convert to volume CLICK TO ADVANCE Plunger (Manually Stroked)

Using the CALIBRATION SYRINGE PLUS to perform the Helium Dilution Test Filled with 79% Nitrogen/21% Oxygen #6 FRC 10 % He 1 up 2 3 Down #9 #5 VT Helium Analyzer Convert to volume Communication Plunger (Manually Stroked) Tube The Calibration Syringe Plus measures every test done in a complete P. F. T. CLICK TO ADVANCE Lung volume test are, performed directly and indirectly. Tidal Volume is breathing while @ rest. When plunger #5 is placed between # ‘s 2 and 3 w/F. R. C. bag #6 attached. FRC bag # 6 is equipped with communication Tube #11 which is connected to the PFT analyzer #9. The FRC bag is filled with air; . air consists of 79% nitrogen and 21% oxygen

Using the CALIBRATION SYRINGE PLUS to perform DLCO Test 3% CO 2 AIR(21% O 2/79% N 2 ) Inflates FRC DLCO BAG #7 #5 #9 Carbon monoxide Analyzer Communication Tube 12 sec. pause Plunger (Manually Stroked) Deflates 3% CO 2 FRC DLCO #5 #9 Carbon monoxide Analyzer Height, weight, age, and sex determine all predicted values. The DLCO #7 technology allows to perform the same test. Not by diffusion but by dilution. The DLCO bag #7 is filled with air (79% nitrogen and 21% oxygen) when plunger # 5 is extended, the air from the DLCO bag #7 and the carbon monoxide from the PFT analyzer #9 is mixed for 10 -20 seconds inside the super syringe #4. Now depress plunger #5 completely, the analyzer does the rest. If volume is important in this test the one way valve can and should be eliminated, then the inspired and expired volume would be equal.

Variable Cuff Pressure Adapter The pressure controller permits the cuff to expand sufficiently to prevent direct flow in the manner desired, but will also divert flow from the endotracheal tube during an expiratory phrase of a breathing cycle allowing the cells in the patients trachea to recover. It provides a fluid-tight fit without creating the danger of stenosis in the patients trachea adjacent to the cuff.
