If pt. tube becomes dislodged & it is impossible to get that obturator in; what should you do next? ~ Answer: •assess the level of respiratory distress ~ •position the patient in the semi- Fowler's position to alleviate dyspnea until assistance arrives ~ •cover the stoma w/ a sterile dressing & ventilate the patient w/ bag- mask ventilation over the nose and mouth on 15L ! 2. Two type of resp. failure in ARDS is? ~ Answer: hypoxia; inadequate o2 to the blood ~ hypercapnia; inadequate co2 removal 3. Hypoxemic respiratory failure is described as? Hypercapnic respiratory failure is described as? ~ Answer: oxygenation failure ~ less than 60 mmHg on greater than 60%oxygen ~ ventilatory failure ~ co2 is greater than 45 & pH is less than 7.35 4. Normally, there is more perfusion than ventilation. What is this called? Absolute shunt ________ ventilation =? ~ Answer: V/Q ~ NO ventilation 5. When it is partial, how would the V/Q be? ~ Answer: a mismatch! 6. Dead space in the alveoli is? ~ Answer: Obstruction to the pulmonary capillary ~ NO perfusion ! 7. Glascow Coma Scale less than 8? ~ Answer: Intubate ! 8. Describe what's happening w/ARDS? What diagnostics would you expect? What are the 3 criteria? How would the timing look? How would the chest xray look? How would the P/F ratio look? ~ Answer: alveolar capillary membrane becomes damaged & permeable to intravascular fluid ~ non- cardiogenic pulmonary edema (there's fluid NOT caused by anything w/the heart) ~ 3criteria: ~ timing (identifiable trauma w/in a week) ~ chest x- ray (bilaterally opacity- completely white out) ~ oxygenation ~ P/F ratio - low (under 99) 9. How would you calculate the P/F ratio? What is the point of this? ~ Answer: take the PaO2 & divide by FiO2 (always in a decimal) ~ assess the degree of impairment in gas exchange w/someone w/ARDS 10. Mild ARDS is ________ mmHg? Moderate ARDS? Severe ARDS? ~ Answer: 200- 300 mmHg ~ 100- 200 mmHg ~ Less than 100 mmHg 11. Complications of PEEP? ~ Answer: ↓venous return ~ ↑intrathoracic pressure ~ damage to the alveoli ~ ↓pre- load ~ hypertension ~ ↑ICP
