Quite often, I hear medical residents reporting during morning rounds that their patients are on Assist Control or SIMV or PCV. I remind them that is a very incomplete statement and that a qualifier word is needed in there during reporting. Otherwise, the report is not very telling of the acuity of the patient.
I remind medical residents that there are :
Modes of Ventilation :
AC (full ventilatory support
SIMV (partial ventilatory support)
PSV (minimal ventilatory support)
and then, there are :
Types of Ventilation :
VCV (volume controlled ventilation)
PCV (pressure controlled ventilation)
PRVC (pressure regulated volume control)
When properly set up in the above grid (like a multiplication table) the relationship becomes obvious.
Types of Ventilation include :
Volume ventilation includes : AC-VCV ; SIMV-VCV ; VSV (volume support ventilation).
Pressure ventilation includes : AC-PCV ; SIMV-PCV ; PSV(pressure support ventilation).
Pressure Regulated ventilation includes : AC-PRVC ; SIMV-PRVC ; VSV (volume support ventilation).
Modes of Ventilation include :
full ventilatory support includes : AC-VCV ; AC-PCV ; AC-PRVC.
partial ventilator support includes : SIMV-VCV ; SIMV-PCV ; SIMV-PRVC.
minimal ventilatory support includes : VSV ; PSV (& NAVA).
