Study: NCT04763746

Intervention type: DEVICE
Intervention: Lifelight Data Collect Sub-protocol 1
Description: Study nurse 1 will announce when the 60-second period of Lifelight® measurement begins and ends, guided by the timer on the software. They will observe the oxygen saturation measurements during this 60-second measurement period, noting down the first reading displayed at 0, 30 and 60 seconds. The three oxygen saturation readings should be averaged to generate a single, average oxygen saturation reading.~Study nurse 2 will operate the automatic sphygmomanometer upon hearing from study nurse 1 that the 60-second measurement period has begun. Study nurse 2 will then spend the remaining measurement period observing the heart rate measurements and note the reading displayed after 0, 30 and 60 seconds. The three heart rate readings should be averaged to generate a single, average heart rate reading.~This sub-protocol will be repeated twice more to generate three sets of blood pressure, heart rate and oxygen saturation measurements and three concurrent video datasets.

Intervention: Lifelight Data Collect Sub-protocol 2
Description: Study nurse 1 will announce when the 60-second period of Lifelight® measurement begins and ends, guided by the timer on the software. They will observe the oxygen saturation measurements during this 60-second measurement period noting down the first reading displayed at 0, 30 and 60 seconds timepoints. The three oxygen saturation readings should be averaged to generate a single, average oxygen saturation reading.~Study nurse 2 will be directed by the announcement of study nurse 1 to begin and end manually counting observed inspirations by watching chest rises throughout the full 60-second period. According to the results of the quality improvement initiative, Study nurse 2 may place their hand on the participant's chest to increase the accuracy of their manual counting.~This sub-protocol will be repeated once more to generate two sets of respiratory rate and oxygen saturation measurements and two concurrent video datasets.

Intervention type: DEVICE
Intervention: Lifelight Data Collect Sub-protocol 3
Description: The study nurse will observe the oxygen saturation measurements during this 60-second measurement period indicated by the timer on the software. They will note down the first reading displayed after 0, 30 and 60 seconds. The three oxygen saturation readings should be averaged to generate a single, average oxygen saturation reading for the 60-second period.~This sub-protocol will be repeated once more to generate two sets of oxygen saturation measurements and two concurrent video datasets.

Intervention type: DEVICE
Intervention: Lifelight Data Collect Sub-protocol 4
Description: Study nurse 1 will announce when the 60-second period of Lifelight® measurement begins and ends, guided by the timer on the software. They will manually count observed inspirations by watching chest rises throughout the 60-second period. They may place their hand on the participant's chest to increase the accuracy of manual counting.~Study nurse 2 will operate a standard automatic sphygmomanometer and clinical finger clip sensor upon hearing from Study nurse 1 that the 60-second measurement period has begun. Study nurse 2 will then spend the remaining measurement period observing these measurements and note the readings displayed after 0, 30 and 60 seconds. The three heart rate and three oxygen saturation readings will each be averaged to generate a single, average reading.~This sub-protocol will be repeated twice more to generate three sets of blood pressure, heart rate, respiratory and oxygen saturation measurements and three concurrent video datasets.
