Diastolic Robotics' Medical Apps
Diastolic Robotics has always been interested in both medicine and engineering.
This page describes some projects where the two fields have a harmonious intersection:
medical software applications.
DRI's medical apps include:
Obstructive Sleep Apnea Screener
Surgical patients with Obstructive Sleep Apnea (OSA) are more likely than non-OSA surgical patients
to suffer post-operative complications. (See: Gupta et al. "Postoperative Complications in Patients
With Obstructive Sleep Apnea Syndrome Undergoing Hip or Knee Replacement: A Case-Control Study" Mayo
Clin Proc. 2001;76:897-905, and Liao et al. "Postoperative complications in patients with obstructive
sleep apnea: a retrospective matched cohort study" Can J Anesth/J Can Anesth (2009) 56:819-828)
The Obstructive Sleep Apnea Screener (OSAS) provides four OSA screening tools including:
The American Society of Anesthesiologists' Checklist
The Berlin questionnaire
The STOP Questionnaire: Snoring, Tired, Observed breathing disruption, high blood Pressure
The STOP-BANG questionnaire: comprised of the STOP Questionnaire with further questions for BMI,
Age, Neck circumference and Gender.
The OSAS software obviates the need for memorization of these tests and referral to textbooks or
journals to administer the screens correctly. Users have access to these screens at their
fingertips. Using these screens, physicians can determine the general likelihood (low or high)
of a patient suffering from OSA. This application will be particularly useful for
anesthesiologists/anesthetists, surgeons and other care providers obtaining patient history prior
to surgery, so that they may be better prepared to deal with complications if they arise.
Once data is input, the likelihood of OSA is recalculated for each category and questionnaire and
the results are displayed at the bottom of the screen. Statements for categories within each test and
for the overall result of the test are shown with highlighting according to the result:
Category results will have either no background to indicate a normal, non-positive result, or
they will have a yellow background to indicate that the patient is positive for that category.
Overall results are color coded blue to indicate a low probability of OSA, or red to indicate
that OSA is likely to be present in the patient according to the particular questionnaire.

Disclaimer and Key EULA Terms
WARNING: This software does not provide a diagnosis nor medical advice,
but only a general likelihood (low or high)
of Obstructive Sleep Apnea. The software is intended to be a convenience
tool providing the screening tests in an accessible and portable format. The software is not
intended to replace a physician's clinical judgement.
This software implements publically available screening tests from peer reviewed
medical and scientific literature. The results echo the tests as presented
in the literature. Diastolic Robotics Incorporated can
guarantee neither the accuracy of the tests nor the applicability of the tests to an individual patient.
It is assumed that the user of the software is a physician who will use their clinical judgement,
and knowledge of these screens to interpret the software's output.
Diastolic Robotics Incorporated and its officers ("DRI") accept no liability for errors or
omissions in the material or data, or for any consequences arising from such errors or omissions,
including any loss which may be incurred as a result of reliance on the accuracy or completeness of
the material or data.

ACTION OF CONTRACT, INSULT OR OTHERWISE, ARISING FROM, OUT OF OR IN
CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE
IN THE EVENT THAT DIASTOLIC ROBOTICS IS FOUND LIABLE FOR ANY LOSS,
ANY CLAIM ARISING OUT OF THE USE OF THIS SOFTWARE SHALL BE LIMITTED TO THE AMOUNT PAID
BY THE USER FOR THE USE OF THE SOFTWARE.
