Measure
Spontaneous Ventilation
Pt's will be allowed to breathe spontaneously through the PLMA during surgery without the assistance of positive pressure ventilation. Spontaneous ventilation: The patient will breathe spontaneously (on their own)while under general anesthesia throughout the duration of the surgery.
Pressure Support Ventilation
Pt's will receive positive pressure assistance with each spontaneous breath through the PLMA. 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
Pt.'s will be placed on the ventilator and ventilated with pressure control. through the PLMA. 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.
