Model 8890 Isolation Valve

Clinical Use Until now, it has been difficult or impossible to monitor exhaled tidal volumes accurately when a patient is on a continuous flow circuit such as IMV, T-piece, CPAP or Bain. Our Isolation Valve permits such monitoring with ease and is very popular for metabolic cart use. Many metabolic evaluation systems now specify this valve. Warning Do not connect valve to any circuit without a pop-off or pressure relief device. Direct connection to a fresh gas flow meter can result in high circuit pressures against which patient cannot exhale. Monitor spirometer when attaching valve to see that exhalation is occurring. Description The Isolation Valve attaches directly to the endotracheal tube or tracheostomy tube. The fresh gas supply (IMV circuit, T-piece, etc.) attaches to the isolation valve so the patient is breathing through the isolation valve. Our Isolaton Valve directs the patients exhaled gas, and only the patients exhaled gas, through the outlet port where it should be monitored by our Mechanical Spirometer or equivalent instrumentation. Advantages Sterilizable by gas, steam autoclave, Cidex, or pasteurizatoin Low resistance to flow Many possible applications in monitoring exhaled volumes, including metabolic measurements Incorporates an end-tidal sampling port for convenient attachment to CO2 gas analyzers and circuit pressure monitors Specifications Patient Port: 15mm ID x 22mm OD Inlet Port: 22mm ID Outlet Spirometry Port: Non-Standard ID, 22mm OD Sampling Port: Female luer lock Materials: Nylon valve body, silicone diaphragm, stainless steel cap screws Flows: Resistance less than 1 cm H2O at 10 l/min Deadspace: 3 cc Dimensions: 3-1/4" x 1-3/4" Weight: 2.5 oz.
