Housing: Plastic Display Gem Case (Pressed on diaphragm and aluminum retaining ring)
Diaphragm Seal: Super Glue
Visual Indicator‡: Dried Nail Polish Layer
Membrane Seal: Generic Super Glue
Testing Details: In an identical manner to the initial test, the LDPE membrane was replaced with a dried layer of nail polish.
Results: Taken by a member of the Stony Brook Volunteer Ambulance Corp (SBVAC), which is in our group, the blood pressure procedure was standardized to the current ideal of the medical community. There was no movement that revealed clear indication of pulse.
Comments: Issues may have included no method of truly testing the seal to ensure air-tightness. Furthermore, the use of super glue appeared to separate the various layers used to ensure that the nail polish membrane was not too thin and thus brittle.
‡ The housing top was not used in the testing of the visual indicator.
