We offer several pneumotachs, catalog numbers 4407, 4408, 4409 (Crossvent2 & Crossvent 2i only), 4409C, infant pneumotach for the Crossvent 2+ and 4410, pediatric/adult pneumotach for the Crossvent 2+ and Crossvent 3+. None of these are interchangeable. The 4407 is distinguished by female luer fittings on the ends of its tubes while the 4408 has male luer fittings on the ends of its tubes. The 4409 has no fittings on the end of its tubes. The 4409C and 4410 have a large white connector on their ends. Check the side of your CV4 to see which fittings you have that will mate with those on the pneumotach. These fittings dictate the matching pneumotach. If your proximal and distal fittings are male on the ventilator, then order the 4407. If female, then order the 4408. If the fittings are male recessed in a hexagon collar, order the 4409. While the 4410 can be used on both the Crossvent 2+ and Crossvent 3+, the 4409C can only be used on the Crossvent 2+. These units have a special flow sensor connector on the left side. Even though it is possible to plug the 4409C into the Crossvent 3+, the unit will inform you that you have plugged the wrong pneumotach in.
We offer three sizes: 64 ml, 500 ml, and 1 liter.
This is caused by the drip cap acting as an amplifier to any resonance created by the diaphragm in the exhalation valve. This can be eliminated by removing the drip cap from the exhaust side of the exhalation valve. Just hold the exhalation valve and pull off the drip cap.
For this we have a 1/4" x 1/4" 1/8" tee (see 8006 on our Accessories page) that will adapt the airway pressure fitting to the 1/8" fitting on the monitors. Simply connect the tube on this tee to the airway pressure fitting on the IC-2A , press the end of the airway pressure line on the breathing circuit onto the tee and run a 1/8" tube (not supplied) from the tee to the monitor.
Acceptable methods of sterilization are:
