Fundamentals of Mechanical Ventilation: A Short Course on the Theory and Application of Mechanical Ventilators 1st Edition PDF
Fundamentals of Mechanical Ventilation 1st Edition EBOOK
New technology now provides several modes by which a patient may be ventilated, with the goals of improved gas exchange, better patient comfort, and rapid liberation from the ventilator.
Moreover, noninvasive positive-pressure ventilation permits some cases of ARF to be managed without insertion of an artificial endotracheal airway, and some patients who are extubated with marginal reserves to avoid reintubation.
Nearly all ventilators can be set to allow full support of the patient on the one hand, and periods of exercise on the other. Thus, the choice of ventilator settings is a matter of physician preference for the majority of patients .
Controlled ventilation with suppression of spontaneous breathing leads rapidly to respiratory muscle atrophy; therefore modes of assisted ventilation are preferred wherein machine-delivered breaths are triggered by the patient’s own inspiratory efforts. Basic modes of assisted ventilation include assist-control ventilation (ACV), synchronized intermittent mandatory ventilation (SIMV), and pressure support ventilation (PSV).
