Measure
Spontaneous Ventilation
Spontaneous ventilation: The patient will breathe spontaneously (on their own) while under general anesthesia throughout the duration of the surgery.
Pressure Support Ventilation
Pressure support ventilation: The patient will breathe on their own and with a little assistance from the anesthesia machine while under general anesthesia throughout the duration of the surgery.
Pressure Control Ventilation
Pressure control ventilation: The patient's ventilation will be completely supported by the anesthesia machine while under general anesthesia throughout the duration of the surgery.
