  1. What newborns are at risk for mecronium aspiration?
    Post term
  2. Waveform in capnography monotoring
    • Baseline, no CO2 being exhaled
    • Rapid rise in CO2, early exhalation – clearing dead space
    • Alveolar Plateau: Alveolar gas exchange
  3. What causes an increase in ETCO2
    • Hypoventilation
    • Respiratory depressant drugs
    • Increased metabolism
  4. Know about favorable prognostics factors for drowning
    • Age: the younger the better
    • Sumersion time: The shorter the better
    • Water Temp: The colder the better
    • Water quality: the cleaner the better
    • Amount of struggle: the less the better
    • CPR quality:
    • Sucidicidal intent
  5. Causes of high methemeglobin
    • normal: 1-2%
    • Nitroglycerin ingestion
    • Teething gels
    • benzocaine
    • Ingestion of well water containing nitratesĀ 
    • cyanosis appears at 15%
    • Brown rusty black blood
  6. What does P50 indicate
    • Expresses the affinity of O2 for hemoglobin
    • Partial pressure of O2 necessary to achieve 50% saturation
    • Normal: 27 for women and 25 for men
  7. Fetal hemoglobin and P50
    • Allows infant to attract O2 from maternal HbA
    • Normal: 20
  8. Calibration of capnograph
    2 point calibration: air and 5% CO2
  9. Patients who would benifit from indirect calimetry
    • Headd trauma
    • COPD
    • Eating disorders
    • Obese
    • Transplant recipients
  10. Respiratory depression
    • RR < 10/minĀ 
    • Very shallow breathingĀ 
    • Patient is unarousable or difficult to arouse
    • RASS: grater than negative 3
  11. Why is Capnography is better at detecting respiratory depression than pulse OX?
    Capnography is a direst measurement of ventilation and pulse ox lags behing with apnea
  12. Patient prep prior to indirect calimetry
    • Patient should be supine 20-30 minutes before, awake and alert but resting
    • Fast 2-4 hours after midnight
    • test time should be free of intruptions
    • Neutral thermal enviroment
  13. Acute epiglottitis
    • Sudden onset of sickness
    • Age 3 to 10
    • Drooling, quite cough
    • Unable to swallow
    • eyes are big
    • Elevated body temp
    • supraglottic inflammation
  14. Croup
    • History of cold in past few days
    • Barking cough
    • Age 5 months to 3 years
    • Stridor at rest
    • Subglottic swelling
  15. meconium aspiration
    • History of meconium-colored amnotic fluid
    • Full term
    • meconium staning about the body
    • Distress
    • Atelectasis
    • mobilize secretions
  16. Smoke Inhalation
    • Cherry red color of face
    • Patient is often confused or unresponsive
    • Stridor
    • Wheezing, ronchi, rales
    • ABG intially decresed PaCO2, normal PaO2
    • ABG later may develop into respiratory distress
    • Decreased lung compliance
    • COHB greater than 20%
    • Keep treating until COHB is below 10%
  17. The different RQ quotients obtained from various sunstrates
    • High fats: 0.71
    • High carb: 1.0
    • Protein:0.82
  18. Patient populations that could benefit from bioimpeadance cardiography?
    • Renal
    • Chronic fatigue syndrome
  19. Alternative methods to measure preoload responsivness
    • leg lift
    • changes in CVP
