Known Issues

Here is a list of known issues:
Last Updated: Sept 2024
  • Very low amplitude cough records not meeting threshold (less than 20db) will be rejected and not considered for assessment.
  • Single bout coughs dominated with silence will not be considered for assessment
  • Coughs with very high background noise are not considered for assessment. Any recording not done by following instructions can result in misdiagnosis
  • Cough recordings are assumed authentic and are from patient only. No validation to reject saying the cough is not from patient.
  • If cough is neither normal nor related to any of the LRT diseases, then the output of the device is generalized by saying it is likely URT infection (without providing details of the type of infection).
  • For pattern output when we are not certain about a given condition as obstructive/restrictive/mixed we consider this as inconclusive.
  • For us to consider the cough signal for prediction, we expect minimum 3 coughs in a recording. Less than 3 will be discarded.
  • When the user updates the app from Play/App store (when new version is available) and if the user is already logged in to the app earlier – the user must logout and login again to get the updates appropriately
  • When a person is giving a cough without taking breath, the device may not always reject the sample. Health professionals are adviced to discard output from device in such conditions.
  • In the scenario when risk is yes and spirometry pattern is abnormal, the disease output can be “No” when the device is unable to detect the disease conditions for Asthma, COPD, COVID-19 and PTB.
  • Swaasa test results may show some variability in accuracy for patients who are actively taking medication, as the medication’s effects could influence the outcome.
  • The spirometry values might show some variation when testing is repeated withing a short duration. This variation is expected within the normal range for healthy people and withing abnormal range for people who are having respiratory problems.
  • It is also understood that the underlying model and clinical trial were created and tested only on adults. The results for children are unknown.
