Exhaled Breath Accessories

On-Line NO Breath Kit — Part #CRBK 01400 For measurement of on-line exhaled NO. The kit includes restrictors calibrated to give flows of 30, 50, 100, 150 200 and 250 mL/s BTPS at ~ 10-15 cm H₂O mouth pressures.
ATS Compliant Bag Collection and Sampling Kit — Part #CBSK 01410 This kit includes an inspiratory gas filter to reduce the concentration of NO in inspired air to < 5 ppb and 12 L Mylar® bags to collect the entire vital capacity at a flow rate of 350 mL/s. The bags are equipped with Luer caps to seal the bag after sample collection. The kit includes adapters and three-way valves for analyzing the samples using the NOA.
Dead-space Discard Bag Collection and Sampling Kit — Part #CBSK 01400 The kit includes the inspiratory gas filter and a valve in the body of the filler to permit discard of the first few hundred milliliters of exhaled breath, then collect the remainder of the breath.
ENO Calibration Gas — Part #CNDK 01400 Calibration of the NOA for gas-phase measurements is easily performed using this lightweight, disposable cylinder of 45 ppm NO in N₂.
Zero Air Filter — Part #CACT 01400 Calibration of the NOA for gas measurement also requires a gas contains low levels (< 1 ppb) of NO. This is easily produced from room air using a cartridge containing KMnO₄ and activated carbon. The trap has sufficient capacity for several years of use.
Calibration Kit — Part #CNCK 01400 Includes the Zero Air Filter, ENO Calibration gas cylinder, a low flow regulator preset to 300 mL/min gas and a calibration tee.
Bacterial/Viral Filters — Part #CAFL 01420 These single-subject disposable bacterial and viral filters provide > 99.9% filtration efficiency for use with the On-Line NO breath kit and the Bag Collection and Sampling Kits. Package of 50.
Thermal Mass Flowmeter — Part #CACC 01420 On-line measurement of exhaled NO requires exhalation at a constant flow rate. The TSI thermal mass flowmeter permits direct measurement of the exhalation flowrate using the NOA 280i or the NOA 280 equipped with the flowmeter upgrade kit (Part # ACC 01487-01). The flowmeter is installed on the On-Line NO Breath kit and the signal processed by the NOA. Calibration is performed using standard calibration syringes (1-3 L) and the NOAnalysis 3.21 REB program. The flowmeter has a fast response time (4 msec) and low pressure drop. The 25.4 mm OD ISO-taper outlet fits over the Accurate NO breath kit mouthpiece and a 22 mm OD ISO-tapered inlet fits the NOA bacterial and viral filters. The polycarbonate body is compatible with standard cold sterilization agents. The flowmeter employs two sensors; a platinum film sensor is heated and maintained at a constant temperature to measure flow and a temperature sensor is used to compensate for changes in gas temperature. Specifications Flow Measurement: Range — 0 - 1.5 L/s BTPS Accuracy — 3.5% of reading at BTPS Weight: 180 grams Dimensions: 182 mm x 64 mm x 53 mm Operating Temp: 0 to 50 °C
