A ventilator is a type of breathing apparatus, a class of medical technology that provides mechanical ventilation by moving breathable air into and out of the lungs, to deliver breaths to a patient who is physically unable to breathe, or breathing insufficiently. Ventilators may be computerized microprocessor-controlled machines, but patients can also be ventilated with a simple, hand-operated bag valve mask. Ventilators are chiefly used in intensive-care medicine, home care, and emergency medicine and in anesthesiology.
A surgical mask, also known by other names such as a medical face mask or procedure mask, is a personal protective equipment used by healthcare professionals that serves as a mechanical barrier that interferes with direct airflow in and out of respiratory orifices. This helps reduce airborne transmission of pathogens and other aerosolized contaminants between the wearer and nearby people via respiratory droplets ejected when sneezing, coughing, forceful expiration or unintentionally spitting when talking, etc. Surgical masks may be labeled as surgical, isolation, dental or medical procedure masks.
A face shield, an item of personal protective equipment (PPE), aims to protect the wearer's entire face from hazards such as flying objects and road debris, chemical splashes, or potentially infectious materials. Depending on the type used, a face shield may protect its wearer from a physical hazard, chemical splashes, or biological hazards.
The maker culture is a contemporary subculture representing a technology-based extension of DIY culture that intersects with hardware-oriented parts of hacker culture and revels in the creation of new devices as well as tinkering with existing ones. The maker culture in general supports open-source hardware. Typical interests enjoyed by the maker culture include engineering-oriented pursuits such as electronics, robotics, 3-D printing, and the use of computer numeric control tools, as well as more traditional activities such as metalworking, woodworking, and, mainly, its predecessor, traditional arts and crafts.
A neck gaiter or neck warmer is a neckwear, or an enlarged collar of a garment, that is worn around the neck for warmth. It is usually a closed tube of fabric, often thick fleece, merino wool, synthetic wicking, or knit material, which is slipped on and off over the head to cover the entire neck and conserve body heat. Some balaclavas are essentially a small hood attached to a neck gaiter. Like gaiters for the lower legs, a neck gaiter augments the protection offered by other garments.
An N95 filtering facepiece respirator, commonly abbreviated N95 respirator, is a particulate-filtering facepiece respirator that meets the U.S. National Institute for Occupational Safety and Health (NIOSH) N95 classification of air filtration, meaning that it filters at least 95% of airborne particles that have a mass median aerodynamic diameter of 0.3 micrometers. This standard does not require that the respirator be resistant to oil; another standard, P95, adds that requirement. The N95 type is the most common particulate-filtering facepiece respirator. It is an example of a mechanical filter respirator, which provides protection against particulates but not against gases or vapors. An authentic N95 respirator is marked with the text "NIOSH" or the NIOSH logo, the filter class ("N95"), a "TC" approval number of the form XXX-XXXX, the approval number must be listed on the NIOSH Certified Equipment List (CEL) or the NIOSH Trusted-Source page, and it must have headbands instead of ear loops.
The COVID-19 pandemic in Canada is part of the ongoing worldwide pandemic of coronavirus disease 2019. It is caused by severe acute respiratory syndrome coronavirus 2. Most cases over the course of the pandemic have been in Ontario, Quebec, British Columbia and Alberta. Confirmed cases have been reported in all of Canada's provinces and territories.
The COVID-19 pandemic in California began earlier than in some other parts of the United States. Ten of the first 20 confirmed COVID-19 infections in the United States were detected in California, and the first infection was confirmed on January 26, 2020. All of the early confirmed cases were persons who had recently travelled to China, as testing was restricted to this group, but there were some other people infected by that point. A state of emergency was declared in the state on March 4, 2020. A mandatory statewide stay-at-home order was issued on March 19, 2020; it was ended on January 25, 2021. On April 6, 2021, the state announced plans to fully reopen the economy by June 15, 2021.
Shortages related to the COVID-19 pandemic are pandemic-related disruptions to goods production and distribution, insufficient inventories, and disruptions to workplaces caused by infections and public policy.
An open-source ventilator is a disaster-situation ventilator made using a freely licensed (open-source) design, and ideally, freely available components and parts. Designs, components, and parts may be anywhere from completely reverse-engineered or completely new creations, components may be adaptations of various inexpensive existing products, and special hard-to-find and/or expensive parts may be 3D-printed instead of purchased. As of early 2020, the levels of documentation and testing of open-source ventilators was well below scientific and medical-grade standards.
The COVID-19 pandemic had a large impact on public transport. Many countries advised that public transport should only be used when essential; passenger numbers fell drastically, and services were reduced. Provision of a reasonable service for the much smaller number of fare-paying passengers incurred large financial losses.
A cloth face mask is a mask made of common textiles, usually cotton, worn over the mouth and nose. When more effective masks are not available, and when physical distancing is impossible, cloth face masks are recommended by public health agencies for disease "source control" in epidemic situations to protect others from virus laden droplets in infected mask wearers' breath, coughs, and sneezes. Because they are less effective than N95 masks, surgical masks, or physical distancing in protecting the wearer against viruses, they are not considered to be personal protective equipment by public health agencies. They are used by the general public in household and community settings as protection against both infectious diseases and particulate air pollution.
During the COVID-19 pandemic, face masks or coverings, including N95, FFP2, surgical, and cloth masks, have been employed as public and personal health control measures against the spread of SARS-CoV-2, the virus that causes COVID-19. With the progress of the pandemic, the public interest in face masks as a means of protection was greatly increased, often even before governments implemented mandatory mask-wearing.
The COVID-19 pandemic in Toronto was a viral pandemic of coronavirus disease 2019 (COVID-19), a novel infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), localized in Toronto. Toronto is the most populous city in Canada, and the fourth most populous city in North America.
The following is a timeline of the COVID-19 pandemic in Canada:
The wearing of non-medical face masks in public to lessen the transmission of COVID-19 in the United States was first recommended by the CDC on April 3, 2020, as supplemental to hygiene and appropriate social distancing. Throughout the pandemic, various states, counties, and municipalities have issued health orders requiring the wearing of non-medical face coverings — such as cloth masks — in spaces and businesses accessible to the public, especially when physical distancing is not possible.
Part of managing an infectious disease outbreak is trying to delay and decrease the epidemic peak, known as flattening the epidemic curve. This decreases the risk of health services being overwhelmed and provides more time for vaccines and treatments to be developed. Non-pharmaceutical interventions that may manage the outbreak include personal preventive measures such as hand hygiene, wearing face masks, and self-quarantine; community measures aimed at physical distancing such as closing schools and cancelling mass gathering events; community engagement to encourage acceptance and participation in such interventions; as well as environmental measures such surface cleaning. It has also been suggested that improving ventilation and managing exposure duration can reduce transmission.
The COVID-19 pandemic in Ottawa is part of the global ongoing viral pandemic of coronavirus disease 2019 (COVID-19), a novel infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Ottawa is the 4th most populous city in Canada, the second largest city in Ontario, and the capital city of Canada.
The United States' response to the COVID-19 pandemic with consists of various measures by the medical community; the federal, state, and local governments; the military; and the private sector. The public response has been highly polarized, with partisan divides being observed and a number of concurrent protests and unrest complicating the response.
Open Source Medical Supplies is a not for profit organization that collates and shares open source designs to make personal protective equipment and other medical supplies needed in the COVID-19 pandemic.
