We break down the real difference between ventilation and oxygenation and explain why mixing them up leads to bad reads on ETCO2, SpO2, and ABGs. Then we open the floor for live Q and A on CRNA admissions, interviews, prerequisites, and ways to strengthen an application.
• Ventilation as a mechanical process moving air and clearing CO2
• How we measure ventilation with tidal volume, respiratory rate, minute ventilation, and end tidal CO2
• Hypoventilation vs hyperventilation and how CO2 shifts drive acidosis or alkalosis
• Oxygenation as gas exchange from alveoli to blood and then to tissues
• How we measure oxygenation with PaO2 and oxygen saturation
• Causes of hypoxemia including diffusion defects and ventilation perfusion mismatch
• Shunt vs dead space with a pulmonary embolus example
• Why adequate ventilation is necessary but not sufficient for good oxygenation
• CRNA school questions on state vs private programs and the importance of accreditation
• Interview advice including staying genuine, avoiding scripted answers, and handling nerves gracefully
• Ventilator modes explained from an anesthesia machine perspective including volume control, pressure control, SIMV, and pressure control with volume guarantee
• Common prerequisite courses and how to approach program specific requirements
• Using graduate level coursework to help offset a borderline GPA
