Device: Legacy Alerting System
Description: Standard alerting system in place at the fire station. Device: Intervention 2: EaseAlert and Legacy Alerting System Description: EaseAlert will activate five second before legacy alerting system activates through a tactile band worn by firefighters. Device: Intervention 3: EaseAlert Standalone Description: EaseAlert will activate and alert the subject of an emergency call without the legacy alerting system. EaseAlert (standalone) replaces the legacy alerting system. |
- Heart Rate (mean) [ Time Frame: Change from baseline Heart Rate to first post interventions (6 days from baseline) and second post intervention (6 days from first post intervention). Outcome will be assessed over 1 day per intervention. ]Heart Rate will be measured with Polar H10 Heart Rate Chest Strap Monitor connected via Bluetooth to wGT3X-BT Actigraphy device. Change from baseline Heart Rate to post interventions
- Heart Rate (max) [ Time Frame: Change from baseline Heart Rate to first post interventions (6 days from baseline) and second post intervention (6 days from first post intervention). Outcome will be assessed over 1 day per intervention. ]Heart Rate will be measured with Polar H10 Heart Rate Chest Strap Monitor connected via Bluetooth to wGT3X-BT Actigraphy device. Change from baseline Heart Rate to post interventions. Max HR will factor subjects' age.
- Sleep Efficiency [ Time Frame: Change from baseline sleep efficiency to first post interventions (6 days from baseline) and second post intervention (6 days from first post intervention). Outcome will be assessed over 1 night per intervention. ]Sleep Efficiency will be measures by wrist actigraphy (device: wGT3X-BT). Actilife 6.0 (issued by ActiGraph Co.) will be used to analyze actigraphy data. Sleep Efficiency is calculated by dividing (total sleep time by total time in bed) X 100. Change from baseline sleep efficiency to post interventions.
- Sleepiness [ Time Frame: Change from baseline afternoon sleepiness to first post interventions (6 days from baseline) and second post intervention (6 days from first post intervention). Outcome will be assessed over 1 day per intervention. ]Sleepiness will be assessed at 1:00 pm on the assessment day using the Stanford Sleepiness Scale (7-point Likert scale: higher scores indicate worse outcome). Change from baseline afternoon sleepiness to post interventions.
- Satisfaction with EaseAlert during Night [ Time Frame: Change from baseline night satisfaction to first post interventions (6 days from baseline) and second post intervention (6 days from first post intervention). Outcome will be assessed over 1 day per intervention. ]Satisfaction with EaseAlert during the night will be assessed with a 10-point VAS Likert scale (lower scores indicate worse outcome) and an open ended option for additional thoughts. Change from baseline night satisfaction to post interventions.
- Satisfaction with EaseAlert during Day [ Time Frame: Change from baseline day satisfaction to first post interventions (6 days from baseline) and second post intervention (6 days from first post intervention). Outcome will be assessed over 1 day per intervention. ]Satisfaction with EaseAlert during the day will be assessed with a 10-point VAS Likert scale (lower scores indicate worse outcome) and an open ended option for additional thoughts. Change from baseline day satisfaction to post interventions.
- Pre-bed anxiety/stress [ Time Frame: Change from baseline pre-bed anxiety/stress to first post interventions (6 days from baseline) and second post intervention (6 days from first post intervention). Outcome will be assessed over 1 day per intervention. ]Pre-bed anxiety/stress will be assessed with a 10-point VAS Likert scale (higher scores indicate worse outcomes) prior to bed. Change from baseline pre-bed anxiety/stress to post interventions.
