Today, I learned about three different modes in the PB-840 ventilator. I learned about the different between volume control, pressure control, and SIMV. Also, I review with my instruction the settings and alarms for the mechanical ventilator. During the say, my RT didn’t have many patients to take care. Therefore, another RT decided to give me a case study about a patient that needs mechanical ventilation. He told me that I have to decide what kind of mode and settings to choose for that specific patient. It was really helpful because I learned two formulas that can help me determinate the desired minute ventilation and PCO2. Today, it was not a busy day but it was a good day to review.
