On-Line NO Breath Kit

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

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

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

Calibration of the NOA for gas-phase measurements is easily performed using this lightweight, disposable cylinder of 45 ppm NO in N2.

CACT 01400

Zero Air Filter

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.

CNCK 01400

Calibration Kit

Includes the Zero Air Filter, ENO Calibration gas cylinder, a low flow regulator preset to 300 mL/min gas and a calibration tee.

CAFL 01420

Bacterial/Viral Filters

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.

CACC 01420

Thermal Mass Flowmeter

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.
