What Does N95 Mean? How and When to Wear an N95 Mask
Over the past few months, it’s safe to say that we’ve all become more aware of the importance of PPE, and the increase in mask wearing during the COVID-19 pandemic, one of the most essential elements of personal protective equipment, has allowed us to appreciate their efficacy like at no other time. Masks help to prevent virus droplets entering the respiratory system and stop an infected person from exposing others to risk, something which has proven critical in the fight against the coronavirus. However, today, people are wearing different types of masks in different environments, and from your standard cotton face covering to the iconic surgical mask, each offers different levels of respiratory protection and filtration efficiency. One of the most widely recognised standards used in medical settings is N95, and many healthcare workers will already be familiar with this type of disposable respirator. These types of masks are used in hospitals, clinics and doctors surgeries but they are also becoming increasingly common outside of these settings as members of the public strive to stop the spread of the virus and protect themselves from airborne contaminants. For those unaware of the difference between a surgical N95 respirator and say, a less protective surgical mask or cotton face covering, here we look at exactly what these highly effective masks entail. Additionally, if you’re currently looking to restock your supplies of PPE, investing in good quality masks is essential, and here we take a closer look at how to wear them and how they can protect you and your patients from infection. What is a N95 Particulate Respirator? A N95 particulate respirator is a face mask that’s designed to filter out particulates as low as 0.3 microns. This type of facemask was originally developed for use in the mining and construction industries, specifically manufactured to protect the wearer from breathing in potentially dangerous particles in the atmosphere. N95 respirators have also been shown to be effective as protection against engineered nanoparticles and other aerosols. Standard N95 respirators will protect the wearer from a range of particles including dust, paint droplets and airborne pollution. They won’t protect against gasses or vapours and they are only effective in the absence of oil particles such as lubricants, cutting fluids and glycerine. If you want to protect yourself from virus droplets and infection, you need to look for a surgical N95 mask. These types of masks are designed to offer a tighter fit around the nose and mouth. This helps to prevent virus droplets being either inhaled or spread by the wearer. Using a N95 respirator mask correctly can significantly reduce the risk of infection and prevent the transmission of a virus. N95 masks that are used in medical settings are not reusable and should be disposed of after each use. However, N95 respirators that are used for industrial purposes can be cleaned and re-worn multiple times. There are some people who may not be able to wear N95 masks. This is because respirators can make breathing more difficult. If you have one of the following conditions, you should talk to your doctor before wearing a face covering. · Emphysema · Pulmonary fibrosis · Claustrophobia · Panic attacks · Heart disease · Anxiety · Autism What is a N95 Approved Mask? When a mask has a N95 rating it shows that it meets the US National Institute for Occupational Safety and Health (NIOSH) N95 classification for air filtration. This standard states that a respirator needs to filter at least 95% of airborne particles. The standard does not require the mask to be resistant to oil. If a mask is N95 approved, it will prevent you from breathing in 95% of the particulates in the air around you. It won’t stop you from breathing oxygen. Only masks that meet this standard can be labelled as N95. These types of masks are also known as N95 filtering face piece respirators, and they are used by professionals in a number of industries including healthcare, construction and mining. How Long Can You Wear a N95 Mask? The length of time you can wear a N95 mask for will vary depending on the setting and the people you are coming into contact with. The CDC says that N95 respirator masks can be worn continuously for up to eight hours without a problem. This length of use is appropriate if you’re only working in healthcare settings where one patient or with a single group of patients are all infected with the same pathogen. If you’re moving between hospital wards or between patients with unknown infections, a new mask should be worn for each occasion. Changing masks on a regular basis helps to prevent cross contamination and protect patients and staff from infection. If you’re moving between patients and don’t have an option to dispose of your mask, wearing a clear visor can help to prevent virus droplets and small particles contaminating the respirator. Is a P2 Mask the Same as N95? When looking for PPE supplies, you may well see some face masks with a N95 rating and others with a P2 classification. Both N95 and P2 masks offer a high level of protection with . N95 masks filter at least 95% of particulates from the air while P2 masks filter 94%. The main difference between the standards is the area of classification. While N95 masks are rated by NIOSH, P2 masks are regulated by the European Union. How Does a N95 Mask Protect Against Viruses? A lot of viruses are spread by airborne particles. These particles are released into the air when an infected person coughs, sneezes or breathes next to a non-infected person. When the virus droplets are inhaled, the non-infected person can catch the virus and become ill. N95 respirators help to protect against the spread of viruses by through particulate filtering that prevents virus droplets in air entering into the mouth or nose. If an infected person wears a N95 mask, the respirator will prevent virus droplets from spreading when the person coughs, sneezes or exhales. If a non-infected person wears a N95 mask, they will be protected from 95% of the virus droplets in the air and have a much lower risk of becoming infected. How to Wear a N95 Respirator? Wearing your N95 respirator correctly will ensure you benefit from the full protection of the face mask. The respirator needs to cover both your nose and mouth and should form an air-tight seal with your face. If you’re not sure how to wear a N95 mask, ask your employer for guidance. What is a N95 Respirator Fit Test? A N95 Respirator Fit Test is used to ensure people using N95 masks know how to properly use the PPE. During the test, employees will be asked to try on a selection of N95 respirators. The person carrying out the test will check to see if the wearer is able to create an air-tight seal between the mask and their face. This is important as an air-tight seal will prevent contaminated air escaping from the mask and also prevent virus droplets entering the mask. Fit Tests should be carried out when this type of mask is first used and then every year after that. Once an employee has established which type of N95 mask fits them best, they should stick to this style for all future use. What Are N95 Mask Sizes? N95 masks are available in a range of sizes. This helps to ensure masks fit the wearer precisely. The way masks are sized varies depending on the manufacturer, and in most cases, you’ll be able to choose from small, small/medium, medium and medium/large sizes. If you work for a company or organisation that requires you to wear a N95 mask, they should provide you with a choice of sizes for your fit test. This will give you the opportunity to try on a few different sizes and find the mask that best fits your face shape. What is a N95 HEPA Mask? HEPA stands for high efficiency particulate air filter. HEPA filters are incredibly effective, removing between 99.95% and 99.999% of particulates from the air while also protecting the wearer from allergens, bacteria, mould, pollution and viruses. N95 respirators aren’t fitted with HEPA filters and only remove 95% of particulates from the air. In most medical settings, a N95 mask will offer sufficient protection. If you need more protection than a N95 mask provides, look for a HEPA air-purifying respirator or N100 respirator instead. What is a N95 Particulate Respirator Made Of? Most N95 particulate respirator masks are made from synthetic plastic fibres. These fibres are woven into a fine mesh and are able to catch at least 95% of particulates that pass through them. Polypropylene is one of the most common polymers used in the production of N95 masks. Where Can You Buy a N95 Mask in Australia? As N95 masks are an important part of PPE, they should always be purchased from a reliable supplier. This is true whether you’re working in construction, mining or healthcare. If you plan to buy a mask from a local hardware shop or another non-specialist retailer, make sure the mask is rated N95 and not KN95. The KN rating shows the product is made in China. And although these masks are supposed to meet the same standards as N95 respirators, NIOSH has found that, in many cases, KN95 masks fall well below standard. A good quality N95 mask will probably cost between $40 and $80. Discounts are often available for bulk orders, so if you’re purchasing on behalf of a clinic, hospital or group, make sure you take a look at the offers available before you buy.

How to Find Your Nearest AED in Australia
An automated external defibrillator, or AED, is an essential piece of life-saving equipment. Used to restore normal rhythm to the heart when a person is in cardiac arrest, an AED can have a big impact on a patient’s chances of survival. In order to help more people survive a cardiac arrest, and give members of the public access to this life-saving tool, AEDs have been installed in a number of locations across Australia. From hospitals and schools to gyms and shopping centres, these publicly available AEDs can help provide fast, effective treatment to a person suffering a cardiac arrest. October 16th is Restart-a-Heart Day in Australia and New Zealand. To mark this important occasion, and to help raise awareness of the importance of AEDs, we’re taking a closer look at these important life-saving tools. What is an AED? AED is used to shock the heart back into a normal rhythm when a person is suffering a cardiac arrest. Unlike heart attacks, which are caused by a blockage in an artery to the heart, a cardiac arrest happens when the heart’s electrical system malfunctions. This malfunction results in abnormal heart rhythms, called arrhythmias, that make it very difficult for the heart to pump blood. The probability of survival decreases by 7% to 10% for every minute that a patient stays in a life-threatening arrhythmia. Quick, effective treatment is the best way to ensure a patient survives a cardiac arrest and isn’t left with long-term injuries. AEDs allow members of the public, or nearby medical staff, to administer life saving treatment before an ambulance arrives. These computerised defibrillators automatically analyse heart rhythms and administer a shock if an abnormal rhythm is detected. As the process is automated, the person using the defibrillator doesn’t need any medical training in order to provide assistance. This can save vital minutes in a medical emergency and help more people to survive a cardiac arrest. Where to find an AED in public places? In order to help members of the public, or medical personal, provide quick treatment to people suffering a cardiac arrest, AEDs are located in public and private buildings across the country. While many AEDs are registered, a lot aren’t. So knowing how to find AED equipment is essential. You’ll commonly find AEDs in large buildings and public locations such as: Hospitals – commonly found on hospital wards and in outpatient areas Community centres – often located in the foyer or reception area Schools – in the staff room or school office Office blocks – in the reception area or foyer Sports clubs – in the reception area or office Gyms – commonly kept close to exercise equipment like treadmills Shopping centres – in central locations like information desks Public libraries – in the reception area If you see someone having a cardiac arrest and are near one of these locations, they should be your first port of call when looking for an AED. When looking for an AED, keep your eyes peeled for an AED wall sign identifying its location. These signs should be installed next to every device to make them easier to find. How to find my nearest AED? There are a number of ways to find your nearest AED in Australia. One option is to head off on foot to one of the locations listed above. This can often be the quickest way of finding an AED. However, as not all offices, schools, sports clubs and gyms will have an AED, there are no guarantees your search will be successful. What’s more, as access to many of these locations will only be possible during opening hours, you’ll have to double check your watch when looking for an AED. The easiest way to find your nearest AED in Australia is to use the AED Locator app. Using the app to find AED machines close to you could save crucial minutes in an emergency. The AED Locator app has been specifically designed to help members of the public locate an AED fast. It uses the GPS on your phone to find your location and match you with the nearest AED. The app features an interactive map that will help you find the AED as quickly as possible. As well as helping you locate your nearest AED, the app allows you to report missing AEDs. This is incredibly important as a missing AED could put someone’s life at risk. You can download the AED Locator app here. Alternatively, you can find your nearest AED by checking the St John’s Ambulance website. This lets you view locations of nearby AEDs and also register an AED if you have one on your property. Click here to visit the St John’s ambulance site. Restart-a-Heart Day On October 16th, Australia and New Zealand will celebrate Restart a Heart Day. Taking place at the same time as Shocktober, an AED awareness campaign by Ambulance Victoria, the day will be used to promote information about cardiac arrests and teach people what to do if they see someone in distress. Every year, around 34,000 Australians and New Zealanders suffer out-of-hospital cardiac arrests. After 10 minutes without intervention, the damage caused by cardiac arrest is nearly irreversible. If you know how to find an AED and what to do when someone has a cardiac arrest, you could significantly boost their chances of survival. To mark Restart-a-Heart Day, we’ll be offering 5% off of AEDs for the remainder of October. Use code: RESTARTHEART5 at the checkout.

Hand Hygiene Australia — The Medshop Guide to Washing Hands Correctly
Australia’s experience of the novel coronavirus has been, to date, less severe than the in US and many European countries. However, as states continue with lockdown measures and the government discusses the possibility of a mandatory app to trace citizens’ contact with confirmed SARS-CoV-2 carriers, it is clear that the threat is far from over. The calls to remain at home or self-isolate, to wear masks and follow stricter hygiene protocols, and to minimise contact with others wherever possible, are now recognised as entirely necessary. The efficacy of these measures abroad is reflected in the flattening of the curve, and as long as everyone recognises these responsibilities, it is hoped that catastrophe can be avoided. So, in order to reaffirm sanitary protocols and remind everyone part of mitigating the spread of the virus is simple as maintaining hand hygiene, here we detail the correct hand washing procedure to keep it fresh in your mind. When to Wash Your Hands Washing your hands should now be routine, and whenever you have returned home after being outside, or after you blow your nose, cough, or sneeze you should wash your hands thoroughly. However, there are plenty of other occasions when you should go through the process, and maintaining good habits now will protect you when lockdown measures are eased. Washing your hands often is important during the crisis, and during these key moments you should take extra care, both before and after: Preparing food Eating and drinking Using the toilet Touching garbage Handling pets Changing nappies or cleaning children Caring for the sick Treating a wound Additionally, with the rise of home deliveries of essential items and food, it is important to wash your hands after receiving packages, bags of food, or other items. Finally, any trip to the pharmacy or handling of pharmaceutical goods should always be preceded and followed by a thorough hand washing. Hand Washing Steps The correct hand washing procedure is simple and only takes a few minutes at most, however, there are a few crucial points that should be adhered to: Remove All Jewellery and Other Items Jewellery such as rings or bracelets make it more difficult to wash your hands thoroughly. Additionally, plasters or bandages should be removed wherever possible as these can be home to pathogens. Once you have completed washing your hands, fresh ones can be applied. Wet Hands and Apply Soap Using warm to hot water, wet your hands thoroughly and apply standard soap or liquid soap. Warm water is generally better as this helps to kill pathogens and allows the soap to work more effectively, however, when used with soap, cold water is also effective. Lather and ScrubLather the soap and scrub your hands for AT LEAST 20 SECONDS. Rub them together, lather the backs of your hands and also between your fingers. Ensure you spread the soap around and under your nails.Rinse Your HandsRinse your hands under warm water where possible and remove all of the soap. Continue rubbing your hands together as you do this. Dry Your HandsWhere possible, dry your hands with an air dryer. Alternatively, a clean towel or paper towel should be used. Dirty towels can help to spread pathogens. Other Points to Think About Following these simple handwashing procedures will help to minimise the threat of transmission of the virus between you, your family, and anyone else you may come into contact with. However, while out of the house, it is important to maintain hygiene standards even when handwashing facilities are difficult to access. In these instances, hand sanitiser or another alcohol-based hand cleaning product should be used to help mitigate infections. While not as effective as handwashing procedures, they can be extremely useful when out and about.
