Ball Pressure Ventilator

Sep 15, 2020 As lung compliance varies with pulmonary disease, a ventilator must be able to deliver a wide range of pressure in inspiration and maintain high pressure at end-exhalation. With a lung compliance of 50 mL/cm H 2 O and an airway resistance of 6 cm H 2 O/L, our ventilator achieved tidal volumes in excess of 500 mL with a PIP of 16 cm H 2 O and a ...

Power To Mechanical Power To Minimize Ventilator

Jul 25, 2019 During controlled mechanical ventilation, mechanical power is composed of parameters set by the clinician at the bedside-such as tidal volume (VT), airway pressure (Paw), inspiratory airflow (V'), respiratory rate (RR), and positive end-expiratory pressure (PEEP) level-plus several patient-dependent variables, such as peak, plateau, and driving ...

Basic Terms And Concepts Of Mechanical Ventilation ...

Gas Flow and Pressure Gradients During Ventilation. An important point in appreciating how ventilation occurs is the concept of airflow. For air to flow through a tube or airway, a pressure gradient must exist (i.e., pressure at one end of the tube must be higher than pressure at the other end of the tube). Air will always flow from the high-pressure point to the low-pressure point.

Physiology

Frequently a rotating bar or ball with a small opening is placed in the path of a high pressure gas. As the bar or ball rotates and the opening lines-up with the gas flow, a small, brief pulse of gas is allowed to enter the airway. Frequencies for HFFI are typically limited to maximum of about 15 hertz. High-frequency ventilation (active)
