Choice of Ventilator Strategy for Different Patients

Abstract

Respiratory gas exchange is limited by the ability of the respiratory muscles to ventilate the lungs, and ventilation fails when the muscles cannot cope with the load imposed by the mechanics of the pulmonary system. It is important to understand the mechanics of breathing, not only to diagnose how the system has failed, and prescribe the correct treatment for the failure, but also to be able to provide the most effective temporary respiratory support using a mechanical ventilator (Polese et al.,2012). There are many methods by which the patient and ventilator interact to perform the ventilatory cycle.These variable techniques are called modes of mechanical ventilation. They are volume targeted modes and pressuretargeted modes (Bozyk et al., 2010). New modes of ventilation promote better oxygenation and faster weaning and be easier to use (Eduardo et al., 2009). The physiology of patients with obstructive lung disease exacerbations presents a unique and complex challenge when these patients are placed on mechanical ventilation. Therefore, ventilator strategies that reduce hyperinflation are crucial (Lougheed et al.,2006). Introduction 2 The concept of ”baby lung“ was introduced and generated interest in the use of low tidal volume ventilation as therapeutic strategy in ARDS (Putensen et al., 2009).
