You are a ICU Respiratory Therapist working in the Medical ICU. You were in the middle of your rounds when you Mr. Campbell’s ventilator alarming continuously. You turn towards the commotion and see that Mr. Campbell, who was intubated a minute ago, has self-extubated. Once you reach the bedside, you assess that the patient is exhibiting mild stridor symptoms and has an elevated respiratory rate. Which of the following would you do based on Mr. Smith’s condition?

You have a patient on CPAP/PSV mode with the settings below:PS=5FiO2=30%PEEP=5Flow Trigger=2Rise Time=50%Patient Data listed below:Spontaneous Respiratory Rate=20Spontaneous VT= 400 mlsVe= 8 L/minI:E=1:4With the given information, what is the patient’s RSBI value?

You have a patient on HFOV with the following parametersDelta P=70 cmH2OHz=12 HzmPaw=32 cmH2OI-Time=33%Bias Flow=40 L/minAn ABG was drawn and the following were the resultspH=7.20PaCO2=60PaO2=60HCO3=22Based on the ABG results, what change if any should you make to improve the results?

This type of trigger is associated with assisted breaths and/or spontaneous breaths. With this trigger, the ventilator delivers a breath when it detects a pressure drop at the proximal airway due to the inspiratory effort of the patient and the ventilator begins the inspiratory phase. Which trigger am I referring to?
