  2. Dead space (physiology) - Wikipedia

    en.wikipedia.org/wiki/Dead_space_(physiology)

    Total dead space (also known as physiological dead space) is the sum of the anatomical dead space and the alveolar dead space. Benefits do accrue to a seemingly wasteful design for ventilation that includes dead space. [1] Carbon dioxide is retained, making a bicarbonate-buffered blood and interstitium possible.

  3. Artificial ventilation - Wikipedia

    en.wikipedia.org/wiki/Artificial_ventilation

    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.

    en.wikipedia.org/wiki/Negative_room_pressure

    Schematic of a network of rooms where air (shown in blue) flows in one direction from the corridor into the negative pressure room (green). Exhaust air is safely removed from the area through a ventilation system. Negative pressure is generated and maintained in a room by a ventilation system that continually attempts to move air out of the ...

  5. Ventilator - Wikipedia

    en.wikipedia.org/wiki/Ventilator

    The history of mechanical ventilation begins with various versions of what was eventually called the iron lung, a form of noninvasive negative-pressure ventilator widely used during the polio epidemics of the twentieth century after the introduction of the "Drinker respirator" in 1928, improvements introduced by John Haven Emerson in 1931, [5 ...

  6. Control of ventilation - Wikipedia

    en.wikipedia.org/wiki/Control_of_ventilation

    The control of ventilation is the physiological mechanisms involved in the control of breathing, which is the movement of air into and out of the lungs. Ventilation facilitates respiration. Respiration refers to the utilization of oxygen and balancing of carbon dioxide by the body as a whole, or by individual cells in cellular respiration. [1]

  7. Negative pressure ventilator - Wikipedia

    en.wikipedia.org/wiki/Negative_pressure_ventilator

    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. [1] [2] [12] [17]

  8. Mechanical ventilation - Wikipedia

    en.wikipedia.org/wiki/Mechanical_ventilation

    Intensive-care ventilators—These ventilators are larger and usually run on AC power (though virtually all contain a battery to facilitate intra-facility transport and as a back-up in the event of a power failure). This style of ventilator often provides greater control of a wide variety of ventilation parameters (such as inspiratory rise time).

  9. Iron lung - Wikipedia

    en.wikipedia.org/wiki/Iron_lung

    An iron lung is a type of negative pressure ventilator, a mechanical respirator which encloses most of a person's body and varies the air pressure in the enclosed space to stimulate breathing. [1] [2] It assists breathing when muscle control is lost, or the work of breathing exceeds the person's ability. [1]
