Navigating through the noise of vent modes.

Modern Ventilators are composed of valves and flow sensors that meter air into the ventilation circuit and thereby the patient. This medical gas delivery is overseen by an embedded microprocessor. Flow sensors can come in a variety of design and require pressure measurements to complete the puzzle of breath delivery. With everything in place the user can do one of two things: Technically they can target pressure or they can target volume delivery at the airway. Many new modes only add garnish to these simple concepts. Utilizing machine learning they can adjust pressure or flow to achieve their volume or minute volume goals. Ultimately the information generated by these systems are critically valuable when coupled with other patient data to produce guidance for weaning or improving support.
