Intermittent assisted ventilation.

[Intermittent mandatory ventilation--I.M.V].

Comparison between intermittent mandatory ventilation and synchronized intermittent mandatory ventilation with pressure support in children.

OBJECTIVE To compare intermittent mandatory ventilation (IMV) with synchronized intermittent mandatory ventilation plus pressure support (SIMV+PS) in terms of time on mechanical ventilation, duration of weaning and length of stay in a pediatric intensive care unit (PICU). METHODS This was a randomized clinical trial that enrolled children aged 28 days to 4 years who were admitted to a PICU be...

Determinants of effective ventilation during nasal intermittent positive pressure ventilation.

Our aim was to verify in healthy subjects submitted to nasal intermittent positive pressure ventilation (nIPPV) with a volumetric ventilator on controlled mode, whether changes in ventilator settings (delivered tidal volume (VT), respiratory frequency (fR) and inspiratory flow (V'I) could influence effective minute ventilation (V'E), thus allowing identification of the settings resulting in the...

Intermittent Mandatory Ventilation Will Live Forever.

in various lung units based on the lung mechanics of the unit. Lung units with long time constants (high airway resistance and/or high compliance) always develop the greatest auto-PEEP, whereas lung units with the shortest time constants (low compliance and/or low resistance) always develop the least auto-PEEP. As shown in the mathematical discussion by Chatburn and Kallet, lung units that are ...

Intermittent Mandatory Ventilation: What's in a Name?

Hence, there is a need for the ventilator, in general, to provide for both spontaneous and mandatory breaths on an intermittent basis. This was the motivation for inventing IMV in the first place, as Kacmarek and Branson mentioned in their paper.1 How does recognition of only type 1 IMV (as in the article by Kacmarek and Branson1) impair our understanding of modes? There are only 3 basic goals ...
