NRS 450 Exam 3 Correct 100%

3 concepts that influence respiratory failure - ANSWER 1. oxygenation: process of providing oxygen for uptake at the cellular level 2. ventilation: process of moving air between atmosphere and lung tissue 3. perfusion: delivery of oxygen rich blood to tissues what is acute respiratory failure - ANSWER -complication of another disease process -RT gas exchange, exchange of O2 and CO2 (need to figure out if its an oxygen problem or CO2 problem) -resp. failure occurs with failure of one or both gas exchange function -acute or chronic, chronic often associated with compensation -results in either hypoxemic (not enough 02) or hypercapnic (insufficient CO2 removal from the blood) diagnosing acute respiratory failure - ANSWER -get from ABG, get PaO2 and PaCO2 -identify the underlying physiological mechanism i.e if O2 is down, then its a oxygen problem so give O2 to fix or if CO2 is high then its a ventilation problem, so fix respiratory drive to blow off CO2
