Choosing Amongst Ventilator Modes
Choice of ventilator mode depends upon the clinical condition of the patient. Choice of ventilator mode can be tailored to achieve specific goals of management and set to achieve spontaneous breathing, volume-targeted ventilation, pressure-targeted ventilation, or some combination. In some conditions, for example in case of spontaneously breathing patient, the patient set the respiratory rate and generates their desired flow rate.[1][2][3] The following are the various ventilator modes and their features:
Pressure support ventilation (PSV)
- This mode supports patient initiated breaths with a set inspiratory pressure and positive end expiratory pressure (PEEP)
- Mode of partial ventilatory support because there is no set rate
- The clinician sets the FiO 2 and PEEP. The patient sets the respiratory rate and generates their desired flow rate.
- After the optimal flow is achieved, the applied pressure can be turned off.
- The volume given depends upon the patient's effort and lung/chest wall compliance
- There is no minimal rate
