CFRN CTRN "Key Points" Sample

1. Flicker vertigo can cause seizures, so cover the patient’s eyes if history of seizures.

2. Avoid succinylcholine (Anectine) in patients with hyperkalemia or history of malignant hyperthermia.

3. Hypemic hypoxia is caused by a lack of RBC’s to carry oxygen, as in anemia (Hypemic = Anemic).

4. Systemic vascular resistance (SVR) is low in distributive shock – neurogenic, anaphylactic, and septic shock. SVR is high in hypovolemic, cardiogenic, and obstructive shock.

5. A “lens-shaped” area appears on head CT in epidural bleed, and a “crescent-shape” in subdural hematoma.

6. Needle decompression is emergency treatment for tension pneumothorax. Needle pericarditis is emergency treatment for pericardial tamponade.

7. Creatine kinase (CK) and potassium are elevated in rhabdomyolysis. Increase IVF’s until urine output > 100 mL/hour. Call receiving facility to prepare for dialysis.

8. 3 to go, 1 to say no - all crew members have the right to refuse a mission if legitimate concern.

9. IABP absolute contraindications – aortic aneurysm, aortic insufficiency, and aortic stents.

10. Fundal height reaches the umbilicus at 20 weeks. Height may be elevated in intrauterine bleeding from placental abruption. Normal fetal heart tones (FHT) are 120-160 bpm. Turn patient 15 degrees to avoid supine vena cava syndrome.

11. Boyle’s law – trapped gas expands with altitude. Barogastralgia occurs on ascent, so unclamp NG tube.

12. “Steeple sign” is seen on chest x-ray in croup. “Thumbprint sign” is seen on lateral neck film in epiglottitis.

13. Cardiac output (CO) is high in the hyperdynamic phase of septic shock.

14. Hypoxia – adjust FiO2 and add PEEP. Hypercarbia – adjust tidal volume and rate.

15. IABP inflates during diastole to increase myocardial oxygen supply.
