Firefighter rehab

Oladipupo Olafiranye, David Hostler, Daniel G Winger, Li Wang, Steven E Reis
Peripheral arterial stiffness and endothelial function, which are independent predictors of cardiac events, are abnormal in firefighters. We examined the effects of aspirin on peripheral arterial stiffness and endothelial function in firefighters. Fifty-two firefighters were randomized to receive daily 81 mg aspirin or placebo for 14 days before treadmill exercise in thermal protection clothing, and a single dose of 325 mg aspirin or placebo immediately following exertion. Peripheral arterial augmentation index adjusted for a heart rate of 75 (AI75) and reactive hyperemia index (RHI) were determined immediately before, and 30, 60, and 90 minutes after exertion...

Most duties performed by firefighters require the use of personal protective equipment, which inhibits normal thermoregulation during exertion, creating an uncompensable heat stress. Structured rest periods are required to correct the effects of uncompensable heat stress and ensure that firefighter safety is maintained and that operations can be continued until their conclusion. While considerable work has been done to optimize firefighter cooling during fireground operations, there is little consensus on when or how cooling should be deployed...

BACKGROUND: Thermal protective clothing (TPC) worn by firefighters provides considerable protection from the external environment during structural fire suppression. However, TPC is associated with physiologic derangements that may have adverse cardiovascular consequences. These derangements should be treated during on-scene rehabilitation periods. OBJECTIVE: To examine heart rate and core temperature responses during the application of four active cooling devices, currently being marketed to the fire service for on-scene rehabilitation, and compare them with passive cooling in a moderate temperature (approximately 24 degrees C) and with an infusion of cold (4 degrees C) saline...

BACKGROUND: Performing fire suppression activities results in cardiovascular stress, hyperthermia, and hypohydration. Fireground rehabilitation (rehab) is recommended to blunt the deleterious effects of these conditions. OBJECTIVE: We tested the hypothesis that three rehydration fluids provided after exercise while wearing thermal protective clothing (TPC) would produce different heart rate or core temperature responses during a second bout of exercise in TPC. METHODS: On three occasions, 18 euhydrated firefighters (16 men, two women) wearing TPC completed a standardized, 50-minute bout of upper and lower body exercise in a hot room that mimicked the National Fire Protection Association (NFPA) rehabilitation guidelines of "two cylinders before rehab" (20 minutes of work, 10 minutes of recovery, 20 minutes of work)...

OBJECTIVE: Develop experimental models to study uncompensable heat stress (UCHS) in working firefighters (FFs). METHODS: FFs ingested core temperature (Tc) capsules prior to performing sequential tasks in 40 degrees C and personal protective ensemble (PPE), or 18 degrees C and no PPE. Both trials were conducted in an environmental chamber with FFs using self-contained breathing apparatus (SCBA). RESULTS: FFs exercising in heat and PPE reproduced UCHS conditions...
