“…This has lead to name “Dual control” ventilation. [910] These adjustments can occur in a single initiated breath or in subsequent breaths and thus form the basis of classification of these modes. Various newer modes available in market are shown in Table 1.…”

The conventional modes of ventilation suffer many limitations. Although they are popularly used and are well-understood, often they fail to match the patient-based requirements. Over the years, many small modifications in ventilators have been incorporated to improve patient outcome. The ventilators of newer generation respond to patient's demands by additional feedback systems. In this review, we discuss the popular newer modes of ventilation that have been accepted in to clinical practice. Various intensive care units over the world have found these modes to improve patient ventilator synchrony, decrease ventilator days and improve patient safety. The various modes discusses in this review are: Dual control modes (volume assured pressure support, volume support), Adaptive support ventilation, proportional assist ventilation, mandatory minute ventilation, Bi-level airway pressure release ventilation, (BiPAP), neurally adjusted ventilatory assist and NeoGanesh. Their working principles with their advantages and clinical limitations are discussed in brief.

“…Occasionally, waveforms with slightly increased shape are adopted in DCV [8,12]. Such strong limitation in waveform modeling of physical parameters controlled by the ventilator, resulting from simplified hardware and software design, reduces drastically the functional versatility of the ventilator performances.…”

“…DCV has been recently introduced in the clinical practice [8]. Before that, with the exception of neonatology, where PCV was preferred since low tidal volume computation and control are both too much critical [9], VCV was mainly adopted [10].…”

“…In detail, DCV is an advanced form of PCV in which the magnitude of selected airways pressure waveform is not kept constant but it is automatically regulated by feedback control for delivering during the inspiratory time either the tidal volume required or, considering the current respiratory frequency, the pre-established volume supplied to patient in every minute (minute volume) [6,7]. This is the so called DCV "breath to breath" mode, representing the most diffused form of DCV in the clinical practice [8,14]. In a different way, the so called DCV "within a breath" mode is a DCV in which the ventilator switches from pressure to volume control in the middle of the inspiratory time [8,14].…”

The theoretical approach along with the rationale of harmonic excitation modality (HEM) applied as optimal dual controlled ventilation (DCV) to anaesthetized or severe brain injured patients, whose respiretory mechanics can be properly assumed steady and linear, are presented and discussed. The design criteria of an improved version of the Advanced Lung Ventilation System (ALVS), including HEM in its functional features, are described in details. In particular, the elimination of any undesiderable artificial distortion affecting the respiratory and ventilation pattern waveforms is achieved by maintaining continuous forever the airflow inside the ventilation circuit, ensuring also the highest level of safety for patient in any condition. In such a way, the full-time compatibility of controlled breathings with spontaneous breathing activity of patient during continuous positive airways pressure (CPAP) or bilevel positive airways pressure (BiPAP) ventilation modalities and during assisted/controlled ventilation(A/CV), includeing also synchronized or triggered ventilation modalities, is an intrinsic innovative feature of the system available for clinical application. As expected and according to the clinical requirements, HEM provides for physiological respiratory and ventilation pattern waveforms together with optimal "breath to breath" feedback control of lung volume driven by an improved diagnostic measurement procedure, whose outputs are also vital for adapting all the pre-set ventilation parameters to the current value of the respiratory parameters of patient. The results produced by software simulations concerning both adult and neonatal patients in different clinical conditions are completely consistent with those obtained by the theoretical treatment, showing that HEM reaches the best performances from both clinical and engineering points of view.
