  2. Mean airway pressure - Wikipedia

    en.wikipedia.org/wiki/Mean_airway_pressure

    Mean airway pressure has been shown to have a similar correlation as plateau pressure to mortality. [6] MAP is closely associated with mean alveolar pressure and shows the stresses exerted on the lung parenchyma on mechanical ventilation. [7] In high frequency oscillatory ventilation, it has been suggested to set the mean airway pressure six ...

  3. High-frequency ventilation - Wikipedia

    en.wikipedia.org/wiki/High-frequency_ventilation

    The rates used vary widely depending upon patient size, age, and disease process. In HFOV the pressure oscillates around the constant distending pressure (equivalent to mean airway pressure [MAP]) which in effect is the same as positive end-expiratory pressure (PEEP). Thus gas is pushed into the lung during inspiration, and then pulled out ...

  4. Zones of the lung - Wikipedia

    Local venous pressure falls to -5 at the apexes and rises to +15 mmHg at the bases, again for the erect lung. Pulmonary blood pressure is typically in the range 25–10 mmHg with a mean pressure of 15 mmHg. Regional arterial blood pressure is typically in the range 5 mmHg near the apex of the lung to 25 mmHg at the base.

    Any Inspiratory Time above 33% can cause air trapping and lead to barotrauma. Setting the Mean airway pressure 1–2 cm of h2O above the set MAP for a few minutes, then weaning back down to the original MAP can recruit alveoli safely.

  6. Nomenclature of mechanical ventilation - Wikipedia

    en.wikipedia.org/wiki/Nomenclature_of_mechanical...

    P plat — Plateau pressure (airway) M paw — Mean airway pressure; E PAP — Pressure applied to exhalation; I PAP — Pressure applied to inhalation; P high — Highest pressure attained, similar to P ip; this is a constant pressure. P low — Pressure that P high drops to during expiratory time (T low) PEEP — Positive end-expiratory ...

  7. Mean arterial pressure - Wikipedia

    en.wikipedia.org/wiki/Mean_arterial_pressure

    In medicine, the mean arterial pressure (MAP) is an average calculated blood pressure in an individual during a single cardiac cycle. [1] Although methods of estimating MAP vary, a common calculation is to take one-third of the pulse pressure (the difference between the systolic and diastolic pressures), and add that amount to the diastolic pressure.

  8. Airway pressure release ventilation - Wikipedia

    en.wikipedia.org/wiki/Airway_pressure_release...

    A pressure-time graphic. Airway pressure release ventilation (APRV) is a pressure control mode of mechanical ventilation that utilizes an inverse ratio ventilation strategy. APRV is an applied continuous positive airway pressure (CPAP) that at a set timed interval releases the applied pressure. Depending on the ventilator manufacturer, it may ...

  9. Modes of mechanical ventilation - Wikipedia

    en.wikipedia.org/wiki/Modes_of_mechanical...

    Airway pressure release ventilation graph. Airway pressure release ventilation is a time-cycled alternant between two levels of positive airway pressure, with the main time on the high level and a brief expiratory release to facilitate ventilation. [5] Airway pressure release ventilation is usually utilized as a type of inverse ratio ventilation.
