Current “Treatments”

Zero-Line

  • This treatment accounts for the difference in height as the  zero line is connected to the transducer. Essentially, it sums up the hydrostatic pressure from the catheter and patient to “zero” out the blood pressure
  • Can accurately calculate Blood Pressure reading
  • Stays in one place and doesn’t need constant adjustment
    • The problem:
      • The device’s setup: it’s complicated
      • Zeroing must be done again if the transducer is moved
        • No air must be present in the zero-line

  • Manual Adjustment
    • The transducer must be placed in a certain position, and must be moved throughout to accommodate the various changes that do occur
    • Can account for changing heights
      • The problems:
        • This method only works with predictable and long-term changes
          • Constant changes, therefore, make this method practically useless
        • This method is inconvenient when the patient’s position constantly changes
