What is Pressure Ventilation? Pressure ventilation or PC is a mode in which the ventilator will • deliver a set pressure − Tidal volume will vary depending on the patient’s compliance and resistance Tidal volume will increase: • − Improved lung compliance −...

Why is Volume Ventilation Preferred? In Pressure Control ventilation, the patient’s tidal volumes • change depending on compliance and resistance. − Because of this, the patient does not receive a consistent minute ventilation Ve = Vt x Respiratory Rate −...

Why is consistent minute ventilation important? Alveolar minute ventilation affects carbon dioxide • removal and PaCO2. − PaCO2=CO2 Production/Alveolar minute ventilation Consistent minute ventilation can aid in keeping a • normal acid/base balance. Severe hypocarbia or severe hypercarbia can • cause rapid changes in cerebral blood flow Rapid changes in cerebral blood flow can cause: •...
