  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. 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]

  4. Pendelluft - Wikipedia

    en.wikipedia.org/wiki/Pendelluft

    Pendelluft is an important physiological concept to take into account during mechanical ventilation, particularly in patients with an open thorax, severe bronchospasm (e.g. asthma or COPD), or with heterogeneous lung compliance (e.g. ARDS). It was first published as a physiological concept in 1956. [2]

    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. Non-invasive ventilation - Wikipedia

    en.wikipedia.org/wiki/Non-invasive_ventilation

    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 ...

  7. 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.
