The main components of flow-restricted, oxygen-powered ventilation devices include An inspiratory pressure safety release valve. A trigger or level positioned to allow both hands to remain on the mask to provide an airtight seal while supporting and tilting the patients head. A peak flow rate of 100% oxygen at up to 40 L/min.
A rudimentary type of mechanical ventilator device that has the advantage of not needing electricity is a flow-restricted, oxygen-powered ventilation device (FROPVD). These are similar to manual resuscitators in that oxygen is pushed through a mask to force-inflate the patient's lungs, but unlike a manual resuscitator where the pressure used to ...
Non-invasive ventilation is used in acute respiratory failure caused by a number of medical conditions, most prominently chronic obstructive pulmonary disease (COPD); numerous studies have shown that appropriate use of NIV reduces the need for invasive ventilation and its complications. Furthermore, it may be used on a long-term basis in people ...
Adult with air entrainment (Venturi) mask. The venturi mask, also known as an air-entrainment mask, is a medical device to deliver a known oxygen concentration to patients on controlled oxygen therapy. [1] [2] The mask was invented by Moran Campbell at McMaster University Medical School as a replacement for intermittent oxygen treatment. Dr.
Artificial ventilation or respiration is when a machine assists in a metabolic process to exchange gases in the body by pulmonary ventilation, external respiration, and internal respiration. [1] A machine called a ventilator provides the person air manually by moving air in and out of the lungs when an individual is unable to breathe on their own.
Heated humidified high-flow therapy, often simply called high flow therapy, is a medical treatment providing respiratory support by delivering a flow of oxygen of up to 60 liters per minute to a patient through a large-bore or high-flow nasal cannula. Primarily studied in neonates, it has also been found effective in some adults to treat ...
The jacket ventilator, also known as a poncho or raincoat ventilator, is a lighter version of the iron lung or the cuirass ventilator, constructed of an airtight material (such as plastic or rubber) arranged over a light metal or plastic frame, or screen, and depressurized and repressurized by a portable ventilator.

Many people with chronic obstructive pulmonary disease have a low partial pressure of oxygen in the blood and high partial pressure of carbon dioxide.Treatment with supplemental oxygen may improve their well-being; alternatively, in some this can lead to the adverse effect of elevating the carbon dioxide content in the blood (hypercapnia) to levels that may become toxic.
