What does F mean on a ventilator?

What is VT in ventilation?
Tidal volume: that volume of air moved into or out of the lungs during quiet breathing (VT indicates a subdivision of the lung; when tidal volume is precisely measured, as in gas exchange calculation, the symbol TV or VT is used.)
What is a normal VT on ventilator?
Protective ventilation refers to the use of low tidal volume (VT), often in the range of 4–8 mL/kg of predicted body weight (PBW). In fact, 6 mL/kg is the normal physiologic VT in humans [4].
What is VT in mechanical ventilation?
When AC mode is selected in the ventilator, four parameters may be quickly modified: Tidal Volume (VT) This is the set amount of volume that will be delivered with each breath.
What does C mean on ventilator?
Assist/Control (A/C)
What is AC mode on ventilator?
Assist-control (AC) mode is one of the most common methods of mechanical ventilation in the intensive care unit. AC ventilation is a volume-cycled mode of ventilation. It works by setting a fixed tidal volume (VT) that the ventilator will deliver at set intervals of time or when the patient initiates a breath.
How is Vt calculated?
VT= VC-(IRV+ERV), VT= TLC-(IRV+ERV+RV).
How is ventilation VT calculated?
*VT is the volume of air inspired/expired with each breath. (Also, VT= IC-IRV. VT= VC-(IRV+ERV), VT= TLC-(IRV+ERV+RV).
What is PSV mode?
Pressure support ventilation (PSV) is a mode of positive pressure mechanical ventilation in which the patient triggers every breath. PSV is deliverable with invasive (through an endotracheal tube) or non-invasive (via full face or nasal mask) mechanical ventilation.
