1. Acute Respiratory Failure occurs when the:
Answer oxygenation, ventilation or bothare inadequate
2. ARF is not considered a:
Answer disease it is a symptom that reflects lung function
3. Hypoxemia causes a decrease in:
Answer arterial O2 and saturation less than normalvalues
4. Inadequate removal of CO2 results in:
Answer Hypercapnia
5. We classify ARF as:
Answer Vhypoxemic or hypercapnic
6. Hypoxemic respiratory failure is a PaO2 less than:
Answer 60mmhg when the patientis receiving an inspired O2 concentration of 60%
7. In hypoxemic respiratory failure (also called oxygenation failure) the mainproblem is:
Answer inadequate exchange of 02 between the alveoli and pulmonary capillaries
8. Hypercapnic respiratory failure or (ventilatory failure) is a PaCO2 greaterthan:
Answer
50mmhg with acidemia (arterial pH less than 7.35)
The main problem is insufficient CO2 REMOVALThis causes the PaCO2 to be higher
