QLFT is a low cost, subjective pass/fail test that exposes the respirator wearer to a chemical stimulant (while donning a test hood) that can only be detected if the respirator leaks. Multiple challenges exist for QLFT, including operator error and fatigue as well as deceitful responses from the person being fit tested, not to mention the bookkeeping challenges it presents. PLEASE NOTE—there’s a better, trusted, OSHA-accepted way todo respirator t testing.  \nUNDERSTANDING, ACCELERATED  \nQUANTITATIVE FIT TESTING  \nHEALTHCARE PROFESSIONALS CAN TRUST  \nEnsure Maximum Protection:  \nQuantitative Respirator Fit Testing (QNFT)  \nThere are two OSHA-accepted QNFT methods for N95 respirators: Generated Aerosol (complex and lack portability) or Ambient Aerosol (simple and portable) . Both methods measure an aerosol challenge agent on the outside of the respirator (Cout) as well as on the inside of the respirator (Cin) as the wearer performs a series of exercises that approximate conditions of use, while the results are recorded. The ratio of the two measurements (Cout/Cin) is called a fit factor. OSHA requires N95 respirators to have a fit factor of at least 100 to pass the fit test. This means that the air inside of a properly donned respirator must beat least 100 times safer than the air outside of the respirator.  \nAmbient Aerosol QNFT:  \nBest OSHA-Accepted FitTest Method  \nSimple and portable, the Ambient Aerosol method of QNFT is the most economical and industry preferred method along with being the best OSHA-accepted fit test method. TSI manufacturers the only ambient aerosol fit tester on the market—the PortaCount® Respirator Fit Tester. The challenge agent used is the ambient microscopic particles that are present at all times in the air we breathe. These particles can’t penetrate the respirator filter, so any particles measured inside the respirator are attributed to a face seal leak.  \nThe PortaCount Fit Tester was first introduced by TSI more than 20 years ago. Today, only the PortaCount Fit Tester can:  \n+ Enable real-time fit optimization  \n+ Facilitate training on proper donning procedures  \n+ Speed up testing time using real-time fit factor technology  \n+ Eliminate errors with automated step-by-step guidance  \n+ Ease record keeping and management of reports  \n+ Go above and beyond regulatory compliance  \n+ Test all types of respirators, including N95  \nCOUT ÷ CIN = FIT FACTOR  \nCOUT  \nCIN  \nAmbient Particle Concentration  \nMask Particle Concentration  \nAs required by OSHA, N95 respirators need to have a fit factor of at least 100 (100 times safer than the air outside of the respirator). For respirators requiring a fit factor >100, quantitative fit testing must be used.  \nQUANTITATIVE FIT TESTING  \nHEALTHCARE PROFESSIONALS CAN TRUST  \nComparison ofFit Testing Methods: QLFT vs QNFT with the PortaCount FitTester  \nIt’s easy to see the advantages QNFT can offer.  \n\n| |  | |\n| --- | --- | --- |\n|  | | Best (Quantitative) |\n| Good (Qualitative) |  |  |\n|  |  |  |\n| Squeeze Bulb |  | PortaCount Pro+\u003Cbr>integrated, automated, step-by-step software test protocol that enables up to four people to be t tested simultaneously using one computer |\n| 75-225 nebulizer squeezes\u003Cbr>per test subject |  | 1 button push, 99% reduction\u003Cbr>in work, 100% reliable |\n| What a Waste!\u003Cbr>+ Tedious process + Prone to errors\u003Cbr>+ Increases need for\u003Cbr>operational resources + Provokes repetitive\u003Cbr>stress disorders ","cbCaigQ5oc14Su7L","https://ap.wps.com/l/cbCaigQ5oc14Su7L","pdf",997246,"English","# Introduction\n## Understanding, Accelerated Quantitative Fit Testing\n# Ambient Aerosol QNFT\n## Best OSHA-Accepted Fit Test Method\n## PortaCount Fit Tester: Saves Time and Money\n# Conclusion","[{\"question\":\"为什么在医疗场景中要做呼吸器密合性检测？\",\"answer\":\"因为合适的呼吸器佩戴与密合才能在工作中提供有效防护。文中指出，通过正确进行密合性检测才能确保你佩戴的是合适型号并获得充分保护。\"},{\"question\":\"QLFT存在哪些主要问题？\",\"answer\":\"文中提到QLFT成本低但主观且存在多种挑战，包括操作人员错误、疲劳影响以及被测试者可能的不真实应答，同时也会带来记录管理难题。\"},{\"question\":\"OSHA对N95定量密合性检测的合格要求是什么？\",\"answer\":\"OSHA要求N95在密合性检测中获得至少100的fit factor才算通过。文中也指出，当需要fit factor大于100时必须使用定量密合性检测。\"},{\"question\":\"Ambient Aerosol QNFT与PortaCount Fit Tester的核心优势是什么？\",\"answer\":\"Ambient Aerosol QNFT被描述为简单、便携、经济，并且更符合OSHA认可的密合性检测方法。PortaCount Fit Tester支持实时密合优化、培训、减少错误的自动引导，以及更高效的测试与报告记录管理。\"}]","Healthcare Professionals Can Trust - Quantitative Fit Testing | PDF",1790470622]
