Proportional assist ventilation in infants

Abstract:
Proportional assist ventilation and respiratory mechanical unloading is a new mode of respiratory assistance that produces similar gas exchange with lower airway pressures than conventional ventilation in infants. This is achieved by tailoring the ventilator pressure contour to the specific derangements in lung mechanics and by a near perfect synchronization with the infant's own inspiratory effort. In contrast to conventional ventilation, PAV only amplifies the effect on ventilation of the spontaneous respiratory effort and relies on the subject's respiratory control. Whether PAV will reduce the incidence of acute complications and chronic pulmonary sequelae in infants needs to be evaluated in randomized controlled trials.

Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
Critical Guidelines for Assessing Ventilation:
Factors Affecting Pulmonary Ventilation
Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...

Ventilatory Modes
There are three ventilatory modes: full support, partial support, and spontaneous. These are described below.
Full Support Modes
Full support modes include controlled mechanical ventilation, continuous mandatory...
