Principles of artificial ventilation

Publication date: Available online 23 January 2019Source: Anaesthesia &Intensive Care MedicineAuthor(s): Ben Brown, Justin RobertsAbstractThe application of intermittent positive pressure ventilation (IPPV) during the 1952 Copenhagen polio epidemic led to the development of the world's first intensive care unit. The requirement for ventilatory support is the most common indication for intensive therapy unit (ITU) admission and is a defining feature of the specialty. Ventilator technology continues to develop and there are many ways to deliver IPPV. The variety of modes of ventilation is increasingly complex and expanding, without evidence that any one mode is associated with improved outcome. Ventilatory support is part of the treatment for a range of conditions including acute respiratory failure, raised intracranial pressure (ICP) and circulatory shock. Ventilator-associated lung injury is reduced by using low tidal volumes and limiting plateau airway pressure to less than 30 cmH2O. Prolonged artificial ventilation has an associated morbidity and mortality and thus should be reviewed by an expert clinician on a daily basis. Weaning aims to identify those patients who will be able to breathe spontaneously. Protocols exist to facilitate timely extubation without the need for re-intubation.

Abstract During the early 1950s, Canada's efforts to prevent polio became heavily influenced by developments in the United States. America's foremost polio charity, the National Foundation for Infantile Paralysis, sponsored University of Pittsburgh researcher Dr. William McD. Hammon to evaluate the efficacy of a human blood fraction, gamma globulin (GG), to prevent paralytic polio. When the resulting clinical trial data appeared to show that the blood fraction offered some protection against the disease, Canadians embraced the concept for reasons of historical trust, parental demand, and public health pragmatism. ...

rke Tyler In 2014, the United States (US) experienced an unprecedented epidemic of enterovirus D68 (EV-D68)-induced respiratory disease that was temporally associated with the emergence of acute flaccid myelitis (AFM), a paralytic disease occurring predominantly in children, that has a striking resemblance to poliomyelitis. Although a definitive causal link between EV-D68 infection and AFM has not been unequivocally established, rapidly accumulating clinical, immunological, and epidemiological evidence points to EV-D68 as the major causative agent of recent seasonal childhood AFM outbreaks in the US. This review su...

After a decades-long reduction in vaccine-preventable illnesses worldwide, there has been a reappearance of childhood illnesses once thought to be eradicated. This resurgence in illnesses such as polio and measles is a consequence of multifactorial events leading to decreased vaccination rates. A lack of resources in poor and war-torn countries, coupled with increasing global travel, and decisions to delay or defer vaccinations because of inaccurate studies further emphasized by media have combined to result in current state of frequent local and widespread epidemics, specifically the current outbreak of measles. As provid...

We are in the midst of a measles epidemic. As of July 25th, more than 1,100 cases have been reported in 30 states since the beginning of the year. That’s the highest number since 1992 — and since measles was declared eliminated in 2000. Given that measles is extremely contagious — the virus can linger in rooms even after a sick person has left — and can lead to serious complications, this is really alarming. There is a simple way to help: get more people immunized. How many children receive vaccines? Most children in the US are immunized. Only a little more than 1% of children have no immunizations....

Discussion Dengue is an important arboviral infection that affects about 40% of the world population. It is found mainly in topical and subtropical areas of the world mainly in developing countries but it range is spreading including the United States. A review of common arboviruses can be found here. It is a flaviavirus with 4 distinct serotypes named DENV-1 through DENV-4 and is spread by A. aegypti a day biting mosquito. Infection with one serotype confers immunity to that serotype but not the others. It does offer some protection for cross-infection but this only lasts a few months. Incubation period is 3-14 days with ...

To the Editor We read with great interest the retrospective case analysis by Elrick et al titled “Clinical Subpopulations in a Sample of North American Children Diagnosed With Acute Flaccid Myelitis, 2012-2016” regarding the definition of more specific diagnostic criteria for acute flaccid myelitis (AFM). We concur with the authors in that the standardized case definition of AFM as adopted by the US Centers for Disease Control and Prevention after the 2014 epidemic is appropriately sensitive in capturing possible AFM cases for epidemiologic surveillance. However, other neurologic entities that cause acute limb ...

Family quarrels are usually private things—unless of course, the family is famous. A public spat among boldface names broke out on May 8, when three members of the Kennedy clan published a piece on Politico declaring that Robert F. Kennedy, Jr.—son of Bobby Kennedy—has been “tragically wrong” in his years-long crusade against vaccines, a crusade that seems especially irresponsible now as the country suffers through its worst measles outbreak since 1994. Kennedy has become a hero of the anti-vax crowd with his persistent claims that vaccines contain deadly ingredients, particularly a mercury-ba...

In this study we have evaluated whether our OMVs vaccine is capable of overcoming the deficiencies of commercial vaccines in both controlling infections caused by PRN(-) isolate/strain and inducing memory immunity. We found that our OMVs-based formulation has a higher protective capacity against the PRN(-) bacteria than that induced with a commercial aP vaccine. We found that CD4 T cells with a tissue-resident memory (TRM) cell phenotype (CD44+CD62LlowCD69+ and/or CD103+) accumulated in the lungs of mice after the second OMVs vaccine immunization. CD4 TRM cells were also detected in mice immunized with wP vaccine, but not ...
