Note that mechanical ventilation does not eliminate the work of breathing, because the diaphragm may still be very active. Synchronized Intermittent-Mandatory Ventilation (SIMV) Guarantees a certain number of breaths, but unlike ACV, patient breaths are partially their own, reducing the risk of hyperinflation or alkalosis.
Pressure support ventilation (PSV) is a form of mechanical ventilation for patients that works with them when they try to breathe, instead of totally controlling the airway. Pressure support ventilation works with patients when they try to breathe, instead of totally controlling the airway.
synchronized intermittent mechanical ventilation; simv Synchronized Intermittend Mandatoryl Ventilation (SIMV) describes a method of providing mechanical breaths to a patient. An "SIMV of 12" means that the patient is getting 12 guaranteed (mandatory) breaths per minute from the ventilator.
