Sensation Intermittent Mechanical Ventilation Mode Research Paper
Synchronized Intermittent Mechanical Ventilation Mode/CareFusion Avea Ventilator
I have chosen the mode Synchronized Intermittent Mechanical Ventilation Mode because it is one of the modes that is most commonly used in the hospital. I wanted to further understand this mode since it is used as an initial mode setting and is also used to wean patients off the ventilator. I will be going over the taxonomy, description of the mode, its purpose & use, and its advantages & disadvantages.
Taxonomy: Volume Control Intermittent Mandatory Ventilation with two set points
(VC- IMV s,s)
Description: Synchronized Intermittent Mechanical Ventilation (SIMV) Mode guarantees a certain number of breaths at a preset frequency, but unlike A/C, patient breaths
are permitted between mandatory breaths. A short window is opened before the scheduled machine triggering of mandatory breaths to allow synchronization with any detected inspiratory effort on the patient’s part. Mandatory breaths are synchronized to coincide with spontaneous respirations. This in turn, reduces the risk of hyperinflation or alkalosis.
Purpose & Use: SIMV is used with the purpose to have the patient breathe spontaneously without the ventilator delivering a mandatory breath with every effort. This mode of ventilation allows the patient to actively participate with the work of breathing (WOB) and receive partial ventilatory support. This mode also allows patient to maintain respiratory muscle strength by avoiding muscle atrophy. With the main purpose of liberation, the mandatory rate is lowered and the patient assumes a greater part of the WOB.
Advantages & Disadvantages:
Advantages Disadvantages
Spontaneous breath allowed Increased WOB
Facilitates ventilation liberation Hypoventilation at low rates
Guaranteed minimum min. volume ventilation Mechanical rate & spont. rate may cause stacking (improper machine sensitivity)
Decreased need for sedatives When used for weaning, if done too quickly may cause muscle fatigue
Lower mean pleural pressures than A/C
