Study Notes
Respiratory Emergencies
- In a patient with a long history of emphysema, if the respiratory rate and depth have decreased, begin assisting ventilations with a bag-mask and 100% oxygen.
- If a patient's respiratory rate and depth have decreased, consider inserting a nasal airway, applying a CPAP unit, and notifying medical control.
Cardiac Emergencies
- A "run" of ventricular tachycardia occurs if at least three PVCs occur in a row.
- A classic sign of atrial flutter is the presence of sawtooth F waves on a cardiac rhythm strip.
- A decreased cardiac output secondary to a heart rate greater than 150 beats/min is caused by decreases in stroke volume and ventricular filling.
- A delta wave is identified on a cardiac rhythm strip as a slurring of the upstroke of the first part of the QRS complex.
- A major complication associated with atrial fibrillation is clot formation in the fibrillating atria.
Medical Emergencies
- A patient with a severe pain between the shoulder blades, described as "ripping" in nature, and a history of noncompliance with antihypertensive medication, may have a difference in blood pressure between the two arms.
- A patient with a head cocked to the side and unable to move it, and a recent history of being placed on Seroquel, may require administration of 25 to 50 mg of diphenhydramine.
Trauma Emergencies
- A pathologic Q wave generally indicates that an acute myocardial infarction has occurred within the past hour.
- The most reliable indicator that significant energy was dissipated by braking before a motor vehicle collision is the presence of tire skid marks at the scene.
- A characteristic of an entry wound that indicates the weapon was fired at close range is the presence of tattoo marks from powder burns.
- To maximize a patient's chances of survival after blunt abdominal trauma, provide basic airway and circulation support at the scene, prompt transport to a trauma center, and IV fluid boluses as needed en route.
- A patient with a femur fracture and a rapidly expanding hematoma on the medial aspect of the thigh may have an arterial injury.
Pediatric Emergencies
- A 6-year-old child who remains in ventricular fibrillation after an initial defibrillation and 2 minutes of CPR requires defibrillation with 70 joules.
Resuscitation
- During cardiac arrest, compressions should be hard and fast, with full chest recoil between compressions.
- A patient who remains in pulseless ventricular tachycardia despite two shocks, a dose of epinephrine, high-quality CPR, and 300 mg of amiodarone requires administration of 150 mg of amiodarone.
- After approximately 6 minutes of attempted resuscitation, a patient who experiences a return of spontaneous circulation requires hypothermia treatment.
- If you witness a person collapse, proceed to assess the person and tell your partner to call 9-1-1 as you begin two-rescuer CPR if needed.
