- Due to the shortage of N95 masks, we have to consider using equally effective alternate options. N95 is a certification issued by US authorities. Masks that have equally effective properties as N95 masks go by different names in different countries based on their independent certification systems. (KN95 – China, P2 – AS/NZ, 1st Class – Korea, DS FFRs – Japan). Considering the life and death situation we face in the hospitals, we have to push our health care administrators to consider getting us these equally effective alternative options since N95s are not available. At the end of the day, we have to prioritize our patient’s health, our health and our families health. I am an internal medicine physician, and I am exposed to patients under investigation (PUI) for COVID 19. Lack of appropriate PPE is putting me at high risk for contracting the virus. This is in turn putting my family and other sick patients I see at risk. Chasing chasing, we know that the N95 mask is a PPE suitable for healthcare providers. At present, the supply of N95 cannot meet the demand. Reasonably priced N95 masks cannot be ordered in bulk until at least late April 2020 or May 2020. Considering our health and our family’s health, first use a reasonably priced KN95 mask. Now, if you do not have access to N95, can you use equally effective alternative options KN95 mask in the US hospitals/private practices/providers? Isn’t using these alternative options better than using a “bandana” or a regular surgical mask or a handmade cloth mask? There are more than a few N95 equivalent masks available worldwide. As per a comparison study performed by 3M – it is reasonable to consider China KN95, AS/NZ P2, Korea 1st Class, and Japan DS FFRs as “equivalent” to US NIOSH N95 and European FFP2 respirators, for filtering non-oil-based particles such as those resulting from wildfires, PM 2.5 air pollution, volcanic eruptions, or bioaerosols (e.g. viruses). These kn95 masks have similar superior properties as N95, but they go by different names based on where they are certified. The WHO (World Health Organizations) considers N95 equivalent to KN95 mask and other similar masks. (WHO Article 1. WHO Article 2.) Although the US authorities recommend using N95 masks, we have to take into account the current situation, and act accordingly. We need to prioritize the safety of our patients, families, and ourselves. All of us should keep in touch with our respective hospital / private practice leaders to promote and advocate the use of equally effective KN95 mask replacements.

Map of Maps – Corrections Please!

[Updated] I’ve now added an “Alert” button beside each map listing on the Map of Maps page. I’ve also fixed the Alert mechanism for the Fixtures page, which was broken for the last month or so due to technical changes by my website host.

If you spot a map in the wrong place, please use the alert button and let me know!

[Update – Confirmed the alert mechanism is working successfully. Send them in!]

Ollie I can’t get onto your main site so thought i’d try you through this. I’m in Birmingham and bought a lovely raleigh racer yesterday – i’m thinking of cycling it to Cambridge in the middle of next month, do you have any suggestions for using online maps to plan a good cyclying route? Getting a map would be the obvious choice…

Facebook is the best way to send me messages. As for cycling routes, have a look at the Sustrans website, they have an online GIS that shows the National Cycle Network routes overlaid on a map. It’s not the greatest GIS I’ve seen but it’s good for what you need. See http://www.sustrans.org.uk/default.asp?sID=1150370275692 and follow the links from there.

From the looks of things, NR53 would be useful but hasn’t been signed yet. So I would get over to just south of Leicester by roads (via Sutton Colefield and Nuneaton) then take NR6 south to Northampton and Milton Keynes, and then NR51 north-east to Bedford, Huntington and Cambridge. Here’s what the route looks like, very roughly: http://www.gmap-pedometer.com/?r=1423799
