Document Summary
Respiratory failure: occurs when the lungs are unable to maintain oxygenation and/or eliminate carbon dioxide. It is the result of another disease process or disorder that is going on in the body. Hypoxia: insufficient oxygen to maintain life processes, leads to inadequate level of tissue perfusion. Hypoxemia: arterial blood oxygen is below normal (<75) Hypercapnia: increased carbon dioxide levels in the blood usually caused by hypoventilation. Respiratory acidosis: decreased ph levels and increase paco2 usually caused by shallow respiration; not blowing off enough co2 and not taking in enough o2. Respiratory distress: sudden progressive form of acute respiratory failure where the alveolar- capillary interface becomes damage and increases the permeability to intravascular fluid. Aspiration, pneumonia, sepsis or trauma to the chest or near drowning. Hypoxemic respiratory failure: pao2 less than 60 with 60% oxygen (non-rebreather or intubation) Caused by vq mismatch, shunting, pneumonia, smoke inhalation, shock, ards, or a pulmonary embolism.
