Release Notes (version 2.9.8.0)

What’s improved/enhanced from prior version?

  • Stability of ASL 5000 plug-in when running ASL 5000 serial number 2500 and above (significantly less chance of freezes)
  • Fixed issue with Play/Stop/Pause functionality within ASL Session Control window
  • Fixed issue with waveform display when volume did not returning to baseline (e.g. Asthma model)
  • Fixed issue where user would see active exhalation when using an apneic model
  • Resolved “noise” oscillations that appeared under certain circumstances on ASL Monitor window
  • Resolved discrepancies that appeared on the CO2 waveforms when using the ASL 5000 during a simulation

Known issues to be improved upon in the future

  • Sometimes upon the start of a simulation, the selected condition does not apply until the user clicks the “apply” button a second time
  • In certain situations, the Live Data PIP reading may display incorrectly depending on the waveform shape

Functionality notes

  • Peak Inspiratory Pressure (PIP) reading from ASL Monitor window may display differently from what is being shown on the ventilator when using Volume Control ventilation. Peak Pressure on ASL Monitor waveform should match closely to PIP from ventilator.
  • The user may experience minor waveform artifact in the ASL Monitor waveforms when using NIV such as CPAP or BIPAP. This artifact is likely attributed to the ASL 5000 sensing turbulent flow and pressure around the NIV mask.
  • Readings from the ASL 5000 with a manikin and ventilator are attempted to be kept within a 10% +/- accuracy range for values such as Flow, Pressure, and Volume. However, since the readings are being taken at two opposite ends of the system there may be instances where the values fall outside this 10% +/- range. These instances can include the use of Lung Models where high amounts of air trapping are present, instances with patient/ventilator asynchrony, the use of ventilators for which a circuit compensation test has not been performed, as well as leaks in the system such as ventilator circuit leak, ETT leak, internal tubing disconnection, or a stuck lung valve. Volume conversion settings may also have to be changed in LLEAP to match the specified settings of the ventilator in use (As Measured vs. BTPS, for example).
