See also respiration (def. Numerous studies have shown this technique to be as effective as, and better tolerated than, intubation and mechanical ventilation in patients with exacerbations of COPD. Inhaled gases are given with positive end-expiratory pressure often with pressure support or with assist control ventilation at a set tidal volume and rate. Ventilation is the act or process of inhaling and exhaling. These example sentences are selected automatically from various online news sources to reflect current usage of the word 'ventilation.' Mechanical ventilatory support that applies positive pressure to the airway. Chest rise, … A ventilatory technique used to treat both premature infants with surfactant-deficient lungs and adults with acute respiratory distress syndrome.Ventilatory support that provides mechanical breaths when the patient's spontaneous breathing does not achieve the preset mechanical ventilatory rate.The normal maximum breathing pattern that can be maintained for 15 min (usually approx. It is determined by subtracting the dead space volume from the tidal volume and multiplying the result by the respiratory rate. A form of mechanical ventilation in which the peak inspiratory flow rate, fraction of inspired oxygen, positive end-expiratory pressure, respiratory rate, and tidal volume are preset and delivered to the patient.At the Forum, experts from China and Germany, with a focus on technologies and standards, discussed the future development of the We analyzed the criteria for outdoor conditions for operating natural Many forms of closed-loop, automatically applied partial support protocols have been developed on many different ventilators; I have reviewed and tried all of them, including mandatory minute
There are numerous indications for endotracheal intubation and mechanical ventilation (see table Situations Requiring Airway Control), but, in general, mechanical ventilation should be considered when there are clinical or laboratory signs that the patient cannot maintain an airway or adequate oxygenation or ventilation. 2 : artificial respiration of the lungs specifically : mechanical ventilation began …
A machine called a ventilator pumps in air with extra oxygen. The objectives include improving pulmonary gas exchange, relieving acute respiratory acidosis, relieving respiratory distress, preventing and reversing atelectasis, improving pulmonary compliance, preventing further lung injury, and avoiding complications. Ventilation: The exchange of air between the lungs and the atmosphere so that oxygen can be exchanged for carbon dioxide in the alveoli (the tiny air sacs in the lungs). This information should not be considered complete, up to date, and is not intended to be used in place of a visit, consultation, or advice of a legal, medical, or any other professional.https://medical-dictionary.thefreedictionary.com/ventilationA noninvasive type of artificial ventilation that relies on displacement of the abdominal contents to move the patient's diaphragm.A mode of mechanical ventilation in which the minute ventilation is not allowed to fall below a set threshold (e.g., in adults, below 100 ml/kg/min), but the inspiratory pressure, inspiratory time, and tidal volume are all adjusted by the ventilator to the patient's needs.A type of mechanical ventilation in which patients breathe spontaneously at any phase of the ventilator's duty cycle at high continuous positive airway pressures (CPAP). facilities or equipment for providing ventilation. It limits the stretching and collapse of the alveoli that occur in conventional mechanical ventilation. A type of assisted ventilation that supplements a spontaneous breath. 1). Dual control is asserted when pressure limited breaths are delivered and the pressure changes from breath to breath to meet a desired delivered tidal volume.
Machine ventilation that delivers pressurized breaths at intervals while allowing for spontaneous breathing.A mechanical method of assisting pulmonary ventilation, using a device that inflates the lungs under positive pressure. Because it is uncomfortable for patients, paralysis and sedation are needed. 1 : the circulation and exchange of gases in the lungs or gills that is basic to respiration. Positive-pressure ventilation can be life saving, but complications such as toxic effects of oxygen, laryngeal injury, tracheal stenosis, alveolar injury, barotrauma, pneumonia, and psychological problems may occur. A type of mechanical ventilation with a minimum frequency of respirations determined by ventilator settings. 60% of maximum voluntary ventilation).The maximum amount of gas that can be ventilated into and out of the lungs in a voluntary effort in a given time, measured in liters per minute.The volume of air inhaled and exhaled in 60 sec. This is called mechanical ventilation.
Modern ventilators are computerized microprocessor-controlled machines, but patients can also be ventilated with a simple, hand-operated bag valve mask.
