Ventilator Basics

Rodrigo Arrangoiz MS, MD, FACS, FSSO
  • Control / target variables:
    • Are the targets that are set:
      • Based on the mode of mechanical ventilation chosen:
        • For example:
          • There are:
            • Pressure-controlled mode of ventilation and
            • Volume-controlled mode of ventilation
        • In pressure-control:
          • The clinician sets a designated pressure:
            • That is delivered with every breath
        • In volume-control:
          • They set a designated tidal volume:
            • That is delivered with every breath
  • Conditional variables:
    • Are the dependent variables:
      • In mechanical ventilation:
        • For example:
          • In volume controlled modes of ventilation:
            • The tidal volume:
              • Is a set parameter
            • While the pressure:
              • Is a conditional variable:
                • And can vary from breath to breath
  • Trigger:
    • The factor that:
      • Initiates inspiration:
        • A breath can be:
          • Pressure-triggered
          • Flow-triggered
          • Time-triggered
  • Cycle:
    • The determination of the end of inspiration, and the beginning of exhalation:
      • For example:
        • The mechanical ventilator can be:
          • Volume cycled
          • Pressure cycled
          • Time cycled

My name is Rodrigo Arrangoiz I am a breast surgeon/ thyroid surgeon / parathyroid surgeon / head and neck surgeon / surgical oncologist that works at Center for Advanced Surgical Oncology in Miami, Florida. I was trained as a surgeon at Michigan State University from (2005 to 2010) where I was a chief resident in 2010. My surgical oncology and head and neck training was performed at the Fox Chase Cancer Center in Philadelphia from 2010 to 2012. At the same time I underwent a masters in science (Clinical research for health professionals) at the University of Drexel. Through the International Federation of Head and Neck Societies / Memorial Sloan Kettering Cancer Center I performed a two year head and neck surgery and oncology / endocrine fellowship that ended in 2016. Mi nombre es Rodrigo Arrangoiz, soy cirujano oncólogo / cirujano de tumores de cabeza y cuello / cirujano endocrino que trabaja Center for Advanced Surgical Oncology en Miami, Florida. Fui entrenado como cirujano en Michigan State University (2005 a 2010 ) donde fui jefe de residentes en 2010. Mi formación en oncología quirúrgica y e n tumores de cabeza y cuello se realizó en el Fox Chase Cancer Center en Filadelfia de 2010 a 2012. Al mismo tiempo, me sometí a una maestría en ciencias (investigación clínica para profesionales de la salud) en la Universidad de Drexel. A través de la Federación Internacional de Sociedades de Cabeza y Cuello / Memorial Sloan Kettering Cancer Center realicé una sub especialidad en cirugía de cabeza y cuello / cirugia endocrina de dos años que terminó en 2016.
