Question

describe the physiological mechanism of volume control an pressure control?

what the strategies to improve oxygenation in a ventilator ?

Answer 1

ANS)

The pressure is not really regulated in any method and the pressure waveform use a parabolic sloping fashion as the lung swell at the time of breathing.Pressure waveform is really changeable at the time of volume control ventilation,altering the appearance/form on the basis of airway resistance and lung compliance.

Some important strategies to improve oxygenation in a ventilator are;

• Enhancing the FIO2.
• Enhancing the mean alveolar pressure,enhancing the mean airway pressure. Enhancing thePEEP. enhancing the I:E ratio
• Re-open alveoli by using the PEEP
