The Propeller System includes the Propeller SMI Model 2014-R Sensor. The sensor is an accessory device intended for
single-patient use to assist physicians and patients in recording and monitoring the actuations of prescribed SMI usage.
The Propeller Mobile Application records, stores, and transmits usage events from Propeller Sensors, or via manual user
entry, to a remote storage system. With the Propeller Mobile Application the user can review information collected
from the SMI sensor, and report and review symptoms and other information about their disease management and its impact.
The user may also share their information with their caregivers, physician, and healthcare providers.
The Propeller Web Application is software that, like the Propeller Mobile Application, is intended to allow users to
review the collected information and characteristics of their SMI and its use, to capture other patient-reported information
and outcomes, and to allow that information to be shared with their caregivers, physicians, and health care providers.
When used under the care of a physician with a prescribed SMI, the system can report on information captured during the
normal course of use, such as the time between actuations that can be helpful in assessing SMI technique.
The Propeller System is intended to be used in populations from Child (>2 years) to Adult.
The Propeller System can be used both indoors and outdoors; home, work, and clinical settings, as well as on aircraft.
The Propeller System may also be used in clinical trials where researchers need to know information about the use of SMI
medication(s) by a participant.
The output of the Propeller System is not intended to diagnose or replace a diagnosis provided by a licensed physician.
The Propeller System is not intended for use as an SMI dose counter, nor is it intended to indicate the quantity of
medication remaining in an SMIL.
