This form of mechanical ventilation includes pressure control ventilation ( PCV), pressure support ventilation ( PSV), and several noninvasive modalities applied via a tight- fitting face mask. In all of these modalities, the ventilator delivers a set inspiratory pressure. What are the modes of mechanical ventilation? If the ventilator senses a spontaneous breath ( negative airway pressure), the ventilator triggers and delivers a full tidal volume to the patient May adjust sensitivity of trigger Patient determines ventilatory rate though minimum back- up rate set to ensure a minimum minute ventilation * Most commonly used mode of ventilation utilized in ICUs. What are mechanics of ventilation? Mechanics of Ventilation. Ventilation, or breathing, is the movement of air through the conducting passages between the atmosphere and the lungs. The air moves through the passages because of pressure gradients that are produced by contraction of the diaphragm and thoracic muscles. ventilation = all modes with RR and fixed Ti) Settings RR, Vt, PEEP, FiO2, Flow Trigger, Flow pattern, I: E ( either directly or via peak flow, Ti settings) Flow Square wave/ constant vs Decreasing Ramp ( potentially more physiologic) I: E Determined by set RR, Vt, & Flow Pattern ( i. for any set peak flow, Square ( ¯ Ti) & Ramp ( ­ Ti) ; Normal Ti: 1. Bradypnea or apnea with respiratory arrest[ 2, 3]. What are the indications for mechanical ventilation? What are the ventilator settings?

    Vents can get fairly complicated but all interns and residents rotating through the ICU should be able to understand the basic principles, settings, and modes used in our medical intensive care unit. ventilator is a machine that takes over the work of breathing when a person is not able to breathe enough on their own. The mechanical ventilator is also called a ventilator, respirator, or breathing machine. There are many reasons why a patient may need a ventilator, but low oxygen levels or severe shortness
