Setting the Ventilato 6. Assist-Control Ventilation 7. Observational studies and clinical trials testing the worth of traditional and innovative approaches to lung protection and gas exchange efficiency characterized scientific efforts in mechanical ventilation through the s and into the first decade of the 21st century [ 24 , 25 ].
Current-generation technology has responded admirably to emerging knowledge concerning iatrogenic upper airway damage, lung parenchymal injury, and the consequences of dys-synchrony [ 26 ].
Present-day approaches - for example, proportional assist ventilation and neurally adjusted ventilatory assist - are immeasurably more effective than before, but still need to eliminate imperfect integration with the patient's neural demands and underlying physiologic needs. Safety and coordination remain the frontiers for scientific investigation and technological development in this field.
Lessons learned The invasive interface Among the first harsh lessons of invasive ventilation was that the protracted presence of an endotracheal tube not only increased the resistance through the upper airway, but also provided a pathway for infection and often damaged irreversibly the delicate tissues of the larynx and trachea.
Even today, the problem of airway debris is difficult to contend with, as the biofilm that lines the unperfused endotracheal tube combined with interruption of the mucociliary escalator and a disrupted coughing mechanism predisposes to retention of contaminated airway secretions [ 27 ]. Accumulation of airway debris causes increased work of breathing, impaires gas exchange, and predisposes to bronchopulmonary infections.
Better materials, lower cuff pressures, and improved nursing practices have addressed some of these problems, but clearly not all of them. In-hospital use of noninvasive ventilation was born from the need to address such issues, and with continually improving interfaces now allows for intubation avoidance, improved sleep quality, and safer treatment of patients with diverse cardio pulmonary problems of moderate severity [ 28 ].
Patient-ventilator interactions Also learned relatively early in the experience with positive-pressure ventilation was the fact that controlling flow rather than pressure could result in high effort and could predispose to breath timing dys-synchrony [ 29 ].
Furthermore, insistence on targeting near-normal pH and partial pressure of carbon dioxide in patients with airflow obstruction often produces dynamic hyperinflation and auto-PEEP [ 15 ]. This pervasive gas-trapping phenomenon, which is nonhomogeneously distributed, impairs breath triggering, increases work of breathing, and may impedevenous return. In patients with expiratory flow limitation, counter balancing auto-PEEP with added PEEP can improve the sensitivity of breath triggering, improve the homogeneity of ventilation, and reduce dyspnea without further lung distention, hemodynamic compromise, or disadvantage to the muscles of the respiratory system [ 30 , 31 ].
Ventilator-induced lung injury High airway pressures and tidal volumes have been shown to damage both healthy and diseased lungs of laboratory animals since the s. Investigations into the causative relationships among mechanical forces, machine settings and cofactors continues to the present day.
It is generally understood, however, that the repetitive application of transalveolar pressures and tidal swings of pressure driving pressure that substantially exceed those normally encountered during normal tidal breathing will give rise to hemorrhagic edema and inflammation that mimic ARDS [ 17 ]. Sustained re-opening of collapsible lung units that are points of stress focusing is, in general, desirable.
But debate continues as to the feasibility and relative importance of fully recruiting all collapsed units, as the latter requires that alveolar pressures do not fall below a high threshold that initiates closure of refractory-dependent units [ 32 ]. Because recruiting unstable alveoli can dramatically reduce the incidence of ventilator-induced lung injury, a persuasive rationale exists for recruiting maneuvers, prone positioning, and the early use of high-level PEEP - the latter obligating use of relatively small driving pressures and accepting resultant hypercapnia when necessary.
We have learned only slowly to account for the important influence of the chest wall on measured values of pressure at the airway opening.
The lung may thus be exposed to lower or higher transalveolar pressures than suggested by the unmodified plateau pressure or PEEP. Even when considering alveoli in different sectors, stresses and strains upon tissues almost undoubtedly vary greatly, in part because of variations in the environment surrounding those lung regions.
Complexity and clinical trials Few rules governing mechanical ventilation apply across all phases and severities of acute illness; choices must be conditioned by stage and by patient response. Yet even those interventions that seem amenable to such dichotomous testing are nuanced by considerations of their dose, duration, timing of use, and patient selection.
Knowing these key principles of effective clinical practice, it is wise to remember that few clinical trials have been undertaken with detailed or proven knowledge of the underlying mechanism driving the outcome variable or have accounted for the complexity and timing of pathophysiology and management.
As a simple example, none of the multicenter cooperative trials of mechanical ventilation yet conducted has assured passivity of the study cohort, despite the implications of muscular effort for the transalveolar pressures that lie at the root of ventilator-induced lung injury.
