1 / 19 1. What is the most reliable method of confirming and montioring correct placement of an ET tube?: Continuous waveform capnography 2. The upper airway consists of...: Nose, Mouth, Jaw, Oral Cavity, Pharynx, and Larynx 3. No gas exchange occurs here , it's called .: Nose to terminal bronchioles, anatomical dead space. (2ml/kg of inspired tidal volume) They conduct airflow towards gas exchange units. 4. Crycothyroid membrane: between thyroid and cricoid, avascular structure that connects the thyroid and cricoid cartilage. Site of CRiCOTHYROTOMY- an emer- gency opening of the airway. 5. A PaCO2 greater than 45 mmHg indicates: A. Metabolic acidosis. B. Metabolic alkalosis. C. Respiratory acidosis. D. Respiratory alkalosis.: C. Respiratory acidosis 6. PaCO2 normal range: 35-45 mm Hg Less than 35 likely means hyperventilation 7. Tracheal deviation AWAY from the affected side, decreased breath sounds, and hyperresonance... What's happening?: Tension pneumothorax 8. In a tension pneumothorax tracheal deviation goes in what direction?: - AWAY from affected side. 9. Normal mean pulmonary artery pressure: 10-20 mmHg 10. Pulmonary hypertension is a mean PA pressure greater than...: (PAm) greater than 20 11. Primary pulmonary hypertension: Idiopathic genetic disorder caused by ab- normal structure of the pulmonary blood vessels 12. Name three causes of secondary pulmonary hypertension..: 1. Passive PH- the result of back pressure. Mitral Stenosis, LV systolic failure. 2. Active PH- Constriction of the pulmonary circuit Increased volume in pulmonary circuit (i.e. congenital heart disease) 3. Obstruction as in Chronic recurrent PE 13. TNP of the Pregnant patient: Resuscitation priorities are the same. The best way to take care of the baby is to take care of mama 14. Mechanisms of injury and biomechanics the most common cause of ma- ternal injury is...: Blunt trauma caused by MVC. Second is BT caused by falls, 3rd is violence 15. fetal distress is an early sign of maternal distress... Why?: Catecholamine mediated vasoconstriction resulting from blood loss shunts blood away from the fetus to the mom. Air Methods Critical Care Exam Questions and Answers Graded A+ 2 / 19 16. Fetal hypo perfusion is evidenced by....: Fetal tachycardia (140 to 160+) and fetal bradycardia 17. The FRC in a pregnant patient is....: Reduced by the gravid uterus lifting the diaphragm. 18. chest tube placement in a pregnant patient is 1-2 spaces higher: Because of the lifted diaphragm 19. What is the cause of physiological anemia in pregnant patients?: Hemodili- tional anemia occurs. Plasma volume increases 30-50%. 20. Preterm Labor (PTL): 21. abruptio placentae: premature separation of the placenta from the uterine wall 22. On a pregnant patient...: Chest compressions must be higher on the sternum. Any preg patient 20 weeks pregnant or more with a uterus above the umbilicus should have the uterus left laterally displaced during compressions to avoid aorto- caval compression. A 15 degree tilt of the long board or lateral displacement. 23. What is the Maternal Fetal Triage Index?: A valid reliable 5 level triage tool that may assist in the triage of obstetric trauma patients
