N95 Respirators

An N95 respirator is a respiratory protective device designed to achieve a very close facial fit and very efficient filtration of airborne particles. Note that the edges of the respirator are designed to form a seal around the nose and mouth. Surgical N95 Respirators are commonly used in healthcare settings and are a subset of N95 Filtering Facepiece Respirators (FFRs), often referred to as N95s.

The similarities among surgical masks and surgical N95s are:

• They are tested for fluid resistance, filtration efficiency (particulate filtration efficiency and bacterial filtration efficiency), flammability and biocompatibility.
• They should not be shared or reused.

N95 Respirators in Industrial and Health Care Settings

Most N95 respirators are manufactured for use in construction and other industrial type jobs that expose workers to dust and small particles. They are regulated by the National Personal Protective Technology Laboratory (NPPTL) in the National Institute for Occupational Safety and Health (NIOSH), which is part of the Centers for Disease Control and Prevention (CDC).

However, some N95 respirators are intended for use in a health care setting. Specifically, single-use, disposable respiratory protective devices used and worn by health care personnel during procedures to protect both the patient and health care personnel from the transfer of microorganisms, body fluids, and particulate material. These surgical N95 respirators are class II devices regulated by the FDA, under 21 CFR 878.4040, and CDC NIOSH under 42 CFR Part 84.

N95s respirators regulated under product code MSH are class II medical devices exempt from 510(k) premarket notification, unless:

• The respirator is intended to prevent specific diseases or infections, or
• The respirator is labeled or otherwise represented as filtering surgical smoke or plumes, filtering specific amounts of viruses or bacteria, reducing the amount of and/or killing viruses, bacteria, or fungi, or affecting allergenicity, or
• The respirator contains coating technologies unrelated to filtration (e.g., to reduce and or kill microorganisms).

The FDA has a Memorandum of Understanding (MOU) with CDC NIOSH which outlines the framework for coordination and collaboration between the FDA and NIOSH for regulation of this subset of N95 respirators.

Variations Edit

N95 8GB (N95-2)Edit

A revision of the N95, called N95 8GB (N95-2, internally known as RM-320), was announced on August 21, 2007, and put on market in October 2007.

The changes compared to the regular version are:

ImprovementsEdit

• 8 GB separate internal memory
• Cosmetic changes to media and front-panel buttons
• New model of handsfree/remote control, AD-54 (as opposed to AD-43 for previous N95 versions)
• New multimedia menu, with Nokia’s Ovi content integration
• Built-in Automatic Screen Rotation (ASR) in software versions v20.0.016 onwards for the N95 8GB version and from v30.0.015 for N95-1, respectively.
• Black faceplate instead of the original silver.

Negative changesEdit

• Pixel density is 142 dpi, compared to 153 dpi for the N95; this is due to the larger display but with the same resolution (QVGA)
• Slider protecting camera lens removed to make room for the larger battery; the camera application is now started by holding down the shutter release button
• Removal of built-in video editor (later added with the firmware upgrades)
• Mass: 128 g, up 8 g from 120 g

N95 NAM (N95-3) Edit

The Nokia N95-3 is a revision of the N95, internally designated as RM-160, designed specifically for the North American market. It is also available in Australian and South American market.

The following was changed from the original version:

• Talk time up to 190 min (WCDMA), up to 250 min (GSM).
• Slider protecting camera lens removed to make room for the larger battery.
• Camera flash moved to the vertical axis of the phone, so when the phone is used as a camera it sits to the side of the camera, instead of below as in the N95-1.
• Cosmetic changes to media buttons.
• Height: 2.05 cm, down from 2.10 cm.
• Mass: 125 g, up from 120 g.
• White keyboard light instead of blue for visibility improvement.
• Current firmware version V 35.2.001, 13-10-09, RM-160

N95 8GB NAM (N95-4) Edit

The Nokia N95-4 (internally known as RM-421) is the North American 3G-compatible version of the N95-2.
The main differences to the N95-2 are:

• Camera lens is now more flush with the phone’s face.
• Multimedia keys are less glossy.
• Users will have to upgrade to at least firmware version 31.2.007 to have automatic screen rotation (ASR) supported. The latest firmware version is 35.2.002 as of December 25, 2009.

N95 8GB CHINA (N95-6) Edit

The N95-6, internally coded RM-321 is a Chinese market-targeted version of the N95-2, lacking 3G and WLAN support just like the N95-5.

General N95 Respirator Precautions

• People with chronic respiratory, cardiac, or other medical conditions that make breathing difficult should check with their health care provider before using an N95 respirator because the N95 respirator can make it more difficult for the wearer to breathe.
• Some models have exhalation valves that can make breathing out easier and help reduce heat build-up. Note that N95 respirators with exhalation valves should not be used when sterile conditions are needed.
• All FDA-cleared N95 respirators are labeled as «single-use,» disposable devices. If your respirator is damaged or soiled, or if breathing becomes difficult, you should remove the respirator, discard it properly, and replace it with a new one. To safely discard your N95 respirator, place it in a plastic bag and put it in the trash. Wash your hands after handling the used respirator.
• N95 respirators are not designed for children or people with facial hair. Because a proper fit cannot be achieved on children and people with facial hair, the N95 respirator may not provide full protection.

Specification sheet Edit

Surgical Masks

A surgical mask is a loose-fitting, disposable device that creates a physical barrier between the mouth and nose of the wearer and potential contaminants in the immediate environment. Surgical masks are regulated under 21 CFR 878.4040. Surgical masks are not to be shared and may be labeled as surgical, isolation, dental, or medical procedure masks. They may come with or without a face shield. These are often referred to as face masks, although not all face masks are regulated as surgical masks.

Surgical masks are made in different thicknesses and with different ability to protect you from contact with liquids. These properties may also affect how easily you can breathe through the face mask and how well the surgical mask protects you.

If worn properly, a surgical mask is meant to help block large-particle droplets, splashes, sprays, or splatter that may contain germs (viruses and bacteria), keeping it from reaching your mouth and nose. Surgical masks may also help reduce exposure of your saliva and respiratory secretions to others.

While a surgical mask may be effective in blocking splashes and large-particle droplets, a face mask, by design, does not filter or block very small particles in the air that may be transmitted by coughs, sneezes, or certain medical procedures. Surgical masks also do not provide complete protection from germs and other contaminants because of the loose fit between the surface of the mask and your face.

Surgical masks are not intended to be used more than once. If your mask is damaged or soiled, or if breathing through the mask becomes difficult, you should remove the face mask, discard it safely, and replace it with a new one. To safely discard your mask, place it in a plastic bag and put it in the trash. Wash your hands after handling the used mask.

Decontaminating Respirators

The FDA has issued Emergency Use Authorizations (EUAs) for the emergency use of decontamination systems for use in decontaminating certain respirators used by health care personnel when there are insufficient supplies of new respirators resulting from the COVID-19 pandemic. New FDA-cleared N95 respirators or NIOSH-approved N95 respirators or other FDA authorized respirators are always the first choice before a decontaminated respirator.

• If a used respirator that is FDA-cleared or NIOSH-approved is available and a new respirator covered under one of the FDA Emergency Use Authorizations for respirators is not available, you may consider decontaminating and reusing the used respirator with a decontamination system that has an FDA Emergency Use Authorization, if the used respirator is compatible with the decontamination system. 
• If your facility is using respirators that have been subsequently removed from Appendix A, these respirators are no longer authorized by FDA for single use or for reuse by an FDA authorized decontamination system.
• Additionally, as of June 6, 2020, any respirator authorized by the Non-NIOSH-Approved Disposable Filtering Facepiece Respirators Manufactured in China, or any respirators with exhalation valves are not authorized to be decontaminated by any of the authorized decontamination systems.
• If you have concerns about respirators or questions about the packaging, labeling, or quality of the respirators, consider replacing, discarding, or returning the respirators to the distributor.

Respirators that are NIOSH-approved before decontamination only retain their NIOSH approval status post-decontamination if the respirator manufacturer permits the use of the decontamination method with the specific system and cycle parameters. To determine the NIOSH approval status of a specific decontaminated NIOSH-approved respirator, please check with the respirator manufacturer.

CDC Recommends Cloth Face Coverings for Use by the General Public

The CDC recommends that members of the public use simple cloth face coverings when in a public setting to slow the spread of the virus, since this will help people who may have the virus and do not know it from transmitting it to others. For more information, see the CDC’s Recommendation Regarding the Use of Cloth Face Coverings, Especially in Areas of Significant Community-Based Transmission.

The best way to prevent illness is to avoid being exposed to this virus. However, as a reminder, the CDC always recommends everyday preventive actions, such as hand washing and maintaining at least 6 feet of social distancing, to help prevent the spread of respiratory diseases.

Comparing Surgical Masks and Surgical N95 Respirators

The FDA regulates surgical masks and surgical N95 respirators differently based on their intended use.

A surgical mask is a loose-fitting, disposable device that creates a physical barrier between the mouth and nose of the wearer and potential contaminants in the immediate environment. These are often referred to as face masks, although not all face masks are regulated as surgical masks. Note that the edges of the mask are not designed to form a seal around the nose and mouth.

An N95 respirator is a respiratory protective device designed to achieve a very close facial fit and very efficient filtration of airborne particles. Note that the edges of the respirator are designed to form a seal around the nose and mouth. Surgical N95 Respirators are commonly used in healthcare settings and are a subset of N95 Filtering Facepiece Respirators (FFRs), often referred to as N95s.

The similarities among surgical masks and surgical N95s are:

• They are tested for fluid resistance, filtration efficiency (particulate filtration efficiency and bacterial filtration efficiency), flammability and biocompatibility.
• They should not be shared or reused.

Вступление

Оригинальная версия Nokia N95 стала великолепным дополнением классической линейки S60-телефонов. Трубка выполнена в форм-факторе «слайдер» и имеет следующие характеристики:

— интерфейс пользователя S60 3rd Edition Feature Pack 1;— передача данных с помощью HSDPA, Bluetooth, Wi-Fi и miniUSB;— отличный большой 2,6-дюймовый дисплей;— великолепная 5-мегапиксельная камера, позволяющая снимать видео высокого качества с разрешением до 640х480 пикселей и монозвуком;— полный набор мультимедийных приложений со всеми аудио- и видеокодеками, возможность редактирования изображений и видео;— возможность работы в портретном или ландшафтном режиме;— встроенный GPS-приемник;— отличная клавиатура и навигационная кнопка;— ТВ-выход, позволяющий насладиться видео или другими приложениями, подключив телефон к телевизору или другому видеооборудованию.

Это весьма неплохой набор функций для телефона, однако, помимо вышеупомянутой бочки меда, имеются всего две, но достаточно большие ложки дегтя. Во-первых, это аккумулятор BL-5F емкостью 950 мА/ч, который просто не в состоянии справиться с электропитанием всех мультимедийных и коммуникационных возможностей. Так что активные пользователи замечают, что телефон не всегда может протянуть даже полный рабочий день, и даже при среднем режиме использования телефона его придется заряжать каждую ночь. Во-вторых, 20 Мб оперативной памяти, доступных после загрузки, более-менее хватает для других устройств с интерфейсом S60 3rd Edition, но явно недостаточно для девайса с такими амбициями, как N95, поэтому памяти часто не хватает, например, при просмотре больших веб-страниц, часто появляются сообщения о различных ошибках памяти.

Взяв на вооружение информацию из отзывов пользователей, Nokia попыталась исправить ошибки, так сказать, «на ходу», выпустив модификацию Nokia N95 8 Гб, которая должна стать достойным флагманским телефоном в 2008 году.

Заключение

Вот, в принципе, и весь список отличий оригинальной версии Nokia N95 от Nokia N95 8GB. Большинство из них положительные, но есть и некоторые негативные стороны, которых лишены владельцы оригинальных телефонов Nokia N95. Это, например, отсутствие защитной шторки на объективе, отсутствие встроенного редактора видео, фиксированный объем встроенной памяти, что не позволяет быстро вынуть карту и вставить ее в принтер. Да и поверхность корпуса оставляет менее приятные осязательные ощущения по сравнению с оригинальной моделью.

Однако в целом телефон Nokia N95 8GB все же лучше своего предшественника: повысилась скорость работы и увеличилась емкость батареи. Кроме этого, несомненными достоинствами являются вдвое увеличенный объем оперативной памяти и большой экран. Качество сборки этой трубки также находится на высоком уровне, причем исправлены некоторые недостатки, замеченные в оригинальной модели.

Компания Nokia внимательно прислушалась ко всем отзывам пользователей N95, конструктивно восприняла критические замечания и отлично поработала над созданием N95 8GB

Оригинальный телефон уже получил несколько обновлений прошивки и позволяет расширить функциональность с помощью приложения Download!, хочется верить, что и новая модель в этом смысле не будет обделена вниманием Nokia

Nokia N95 8GB, без сомнения, можно назвать самым лучшим на сегодняшний день телефоном. Это устройство можно без преувеличения называть мультимедийным компьютером. Он отличается от настоящих компьютеров разве что небольшим размером экрана, ведь QVGA-дисплей ограничивает комфортность просмотра Интернет-сайтов и работы с документами, и отсутствием клавиатуры. Хотя последний недостаток легко может быть исправлен с помощью портативной беспроводной Bluetooth-клавиатуры.
