Spontaneous Breathing Trial (SBT)
Analyzing readiness of extubation is commonly done by switching from the current operation mode of the ventilator to a spontaneous mode with different support levels.
There are risks involved with leaving the patient in this mode if not yet ready.
Alarms must be correctly adjusted to detect conditions which indicate that the patient is not ready and his condition is degrading. Once alarms occur, the clinician must return the ventilator to the previous mode and adjust the alarms and settings back to what they were prior to the breathing trial. This can result in many errors and suffering of the patient.
In the Panther ventilators, SBT is incorporated to streamline this operation. The clinician sets the required SBT settings such as time, PS, PEEP and others and activates SBT.
The SBT automatically switches the ventilator to spontaneous mode with the SBT selected settings for the defined period of time.
A set of monitored data such as SpO2, rate and minute volume are constantly evaluated to detect if the patient’s state is declining. Based on this analysis, if deemed necessary, the ventilator will automatically switch back to the pre-SBT mode and restore all settings and alarms.
This both increases patient safety as well as reduces clinician burden of constantly checking on the patient.
