Not all filters are created equal in respiratory care \u2014 even when they look the same on the product sheet. The leap from a standard filter to an advanced respiratory filter is not necessarily in the specs, but rather in the real world use of the filter in clinical settings.<\/strong><\/p>\n\n\n\n The hospital, distributor, and OEM buyer\u2019s question is typically not \u201cwhich one is better\u201d but rather, when does an advanced respiratory filter make sense?<\/p>\n\n\n\n A standard respiratory filter is a general term and usually means a basic bacterial\/viral filter used in:<\/p>\n\n\n\n General ventilator circuits Typically they:<\/p>\n\n\n\n Offer repeatable BFE\/VFE performance \u2018Standard\u2019 Backed Pretty Modimo Ltd<\/p>\n\n\n\n \u2018Good enough,\u2019 meaning, it meets all core requirements and has reasonable specifications at a competitive price that works in most standard breathing circuits.<\/p>\n\n\n\n An advanced respiratory filter takes the base product and improves upon the product filter with refinements and stability rather than on huge headline figures for efficiency.<\/p>\n\n\n\n Advanced respiratory filters might consist of:<\/p>\n\n\n\n Multi-layer composite filtration On paper, both willThe real difference is in how long that performance lasts, or whether for example, the performance suffers.<\/p>\n\n\n\n Standard filters:<\/p>\n\n\n\n So, they work in dry conditions, but despite the caveat air must have some other, or their performant quality will be less good in humid conditions – and as condensate forms, \u201cquenching\u201d with water leads to more resistance that some will see their performance degrade that too – more to lose, as it were.<\/p>\n\n\n\n Advanced respiratory filters:<\/p>\n\n\n\n Work nicely in high humidities, and so most all our filters will not just one linear point so to speak, but across the full range of exposure times and operating conditions. This is for: ICU ventilation etc, using with humidifier chambers, or enjoying longer (long?-) duration anaesthesia etc.<\/p>\n\n\n\n Standard filters;<\/p>\n\n\n\n So they start out, \u201cokay\u201d – with acceptable resistance, but quenched with some water vapour, etc and this might change and increase as moisture builds.<\/p>\n\n\n\n Advanced<\/p>\n\n\n\n Most keep stable airflow characteristics making for better patient care etc.<\/p>\n\n\n\n Standard filters;<\/p>\n\n\n\n A couple of time applies, short to medium time, they do this, thus satisfactory for most procedures.<\/p>\n\n\n\n Advanced respiratory filters;<\/p>\n\n\n\n These are effective over slightly longer ventilation cycles and extended exposures.<\/p>\n\n\n\n Standard filters;<\/p>\n\n\n\n Work away but as just components, so are the smallHME\/HMEF etc<\/p>\n\n\n\n Advanced:<\/p>\n\n\n\n But some, work as part, designed and thought out as part of a\u201d, \u201cbreathing system\u201d specifically with specific circuit ventilator set\/rig in mind. For example this could be a deal breaker for the R+D side of an OEM project etc<\/p>\n\n\n\n Standard filters;<\/p>\n\n\n\n Which are satisfactory in so doing, for their purpose.<\/p>\n\n\n\n Advanced respiratory filters;<\/p>\n\n\n\n Are risk managed, so have more security in patients you care in difficult conditions.<\/p>\n\n\n\n An advanced filter is not used everywhere that respiratory filters are. They tend to be preferred in:<\/p>\n\n\n\n \u2022 High humidity ICU ventilation In many cases, a standard filter will be adequate. These include:<\/p>\n\n\n\n \u2022 Short procedures Understanding this helps ensure that we are not over specifying.<\/p>\n\n\n\n So a large part of what goes under the name of advanced respiratory filter these days is simply the result of improvement in:<\/p>\n\n\n\n \u2022 HME filters These are product designs where other functions such as:<\/p>\n\n\n\n \u2022 Filtration Have been included along with the filter. The classic improvements on the \u201cstandard\u201d include:<\/p>\n\n\n\n \u2022 Better moisture retention This is where a lot of the real product differentiation happens.<\/p>\n\n\n\n It\u2019s easy to be fixated on specification when you look at standard and advanced respiratory filter. In practice, a better way to look at them is:<\/p>\n\n\n\n \u2022 Will this filter be used in conjunction with active humidification Ultimately the difference between a respiratory filter standard and advanced is performance under actual use, not just on paper. So, we can all agree, standard respiratory filters are reliable, with great cost effectiveness, and applicability to routine use situations. Advanced respiratory filters are for demanding situations and provide for more stable loads with predictable moisture and airflow performance over time. In addition, for the OEM and the manufacturer, it is no longer safe to just assume advanced is better.<\/p>\n\n\n\n <\/p>","protected":false},"excerpt":{"rendered":" \u00a0Standard vs Advanced Respiratory Filters Not all filters are created equal in respiratory care \u2014 even when they look the same on the product sheet.
