  2. Breathing circuit - Wikipedia

    en.wikipedia.org/wiki/Breathing_circuit

    The breathing circuit may be open, closed, or semi-closed, depending on whether breathing gas is recycled. A closed or semi-closed circuit will include components which remove carbon dioxide from the exhaled gas and add oxygen before it is delivered for inhalation, so that the mixture remains stable and suitable for supporting life.

  3. Ventilator - Wikipedia

    en.wikipedia.org/wiki/Ventilator

    Determined by the type of ventilation needed, the patient-end of the circuit may be either noninvasive or invasive. Noninvasive methods, such as continuous positive airway pressure (CPAP) and non-invasive ventilation , which are adequate for patients who require a ventilator only while sleeping and resting, mainly employ a nasal mask.

  4. Mechanical ventilation - Wikipedia

    en.wikipedia.org/wiki/Mechanical_ventilation

    Mechanical ventilation or assisted ventilation is the medical term for using a ventilator machine to fully or partially provide artificial ventilation. Mechanical ventilation helps move air into and out of the lungs, with the main goal of helping the delivery of oxygen and removal of carbon dioxide.

    Note: ( In cases with an apneic patient the best results will be achieved using the Two person bag-valve-mask technique.) Proper training and considerable practice is required to correctly use the FROPVD devices. [3] The main components of flow-restricted, oxygen-powered ventilation devices include An inspiratory pressure safety release valve.

  6. Neurally adjusted ventilatory assist - Wikipedia

    en.wikipedia.org/wiki/Neurally_Adjusted...

    Neurally adjusted ventilatory assist (NAVA) is a mode of mechanical ventilation. NAVA delivers assistance in proportion to and in synchrony with the patient's respiratory efforts, as reflected by an electrical signal. This signal represents the electrical activity of the diaphragm, the body's principal breathing muscle. [1]

  7. Heated humidified high-flow therapy - Wikipedia

    en.wikipedia.org/wiki/Heated_humidified_high...

    Heated humidified high-flow therapy, often simply called high flow therapy, is a type of respiratory support that delivers a flow of medical gas to a patient of up to 60 liters per minute and 100% oxygen through a large bore or high flow nasal cannula. Primarily studied in neonates, it has also been found effective in some adults to treat ...
