The PainChek® Infant App is a mobile application that is downloaded from the Apple App Store or the Google Play Store and it is generally used in much the same way as any other App.
Devices running the PainChek® Infant App should be used, charged, maintained and disposed of according to the standard instructions provided their manufacturer.
PainChek® is a software system which is comprised of the following components:
a) PainChek® Infant App
b) PainChek® Portal
PainChek® Infant is intended to be used to assess and monitor procedural pain in infants (i.e., 1 to 12 months old) by trained health care professionals (HCPs).
Indications for Use
Procedural pain assessment where procedural pain is defined as short-lived acute pain associated with medical investigations and treatments conducted for the purpose of health care.
Procedures range from minor procedures such as intravenous cannulation, venepuncture, finger and heel pricks, immunisations, suturing and dressing changes to more invasive procedures, such as lumbar punctures, fracture reductions and bone marrow biopsies; and may occur in a variety of settings, including but not limited to, hospitals, day surgery centres, ambulatory care clinics, general practice, dental clinics.
PainChek® Infant is not intended to specify or recommend any clinical diagnosis, treatment or interventions. It is not the intent that the user, as a health care professional (HCP) rely primarily on any of such recommendation from the use of PainChek® Infant. The HCP independently reviews the recommendation and makes all clinical diagnosis or treatment decision.
PainChek® Infant is advised to be used with caution on infants born with craniofacial birth defects, including but not limited to the below, considering that each will have varying degrees of clinical presentation:
Cleft lip and cleft palate
Vascular birthmarks and haemangiomas
The PainChek® Infant App has an intelligent pain assessment feature which provides a point-of-care application that uses a smart-device camera to capture images of the infant’s face over a period of time. These images are then analysed in real-time using facial recognition and analysis technology to detect muscle movements which are indicative of the presence of pain, resulting in an automatic calculation of a pain score. The PainChek® Infant App has a graphing function which allows monitoring the infant’s pain over time.
The PainChek® Portal is a secure website that allows users to manage infant data, PainChek license, facilities, users, installations and customise PainChek® profile settings.
The PainChek® Infant App is a software application that assists trained healthcare professionals and lay persons in assessing the levels of pain in infants. The PainChek® Infant App uses automated, real-time facial analysis which can detect pain related facial micro-expressions to indicate pain intensity.
The software can be downloaded and supported by most iOS mobile devices, including smartphones and tablets.

Warnings and Cautions
Automated Facial Assessments
The PainChek® Infant App requires the child's face be unobstructed and the child to be as still as practical in order to capture video of sufficient duration to allow for an automated facial assessment.
It might not be possible to perform an automated facial assessment due to:
The child's face not being clearly visible
The child is moving too much
Suboptimal lighting conditions
In these instances attempt to remediate lighting conditions (increase lighting if dull, remove excessive glaze, use a dark background for contrast for babies with pale skin, minimise or remove environmental stimulation or console the infant to minimise head movement.
