As a patient who knows about the Spontaneous Breathing Trial option, I'm a long term ventilator dependent, and I use the SBT function to set the ventilator to CPAP/PS for a few minutes. It has a timer obviously, so It'll go back to assist control after the time has Elapsed. It gives me a chance to breathe on my own with high Pressure Support for a few minutes. I know the Respiratory Field very well. VERY VERY well, and so I know how to use this option. It is a WONDERFUL option that most home care patients have no idea, but I know what an SBT is, so I use it to do short trials off the ventilator.
The profile information is incorrect, backwards actually. The correct statement is the smaller the patient the lower the profile. Example:Infants profile 1 vs adult profile 9. See manual
