Introduction:
This article discusses the correlation between sensory processing sensitivity (SPS) as a feature of personality and temperament and paramedics' subjective perception of noise inside an ambulance. Description of the theoretical basis of SPS has been strongly depicted.
Materials And Methods:
: Polish translation of SPS 12-item short scale and a survey concerning the subjective perception of noise inside an ambulance have been used in this research. Assessment of noise included its three sources: emergency vehicle siren, resistance of rolling tires and noise produced by diesel engines. 46 paramedics from mobile emergency care units working in Poznan and the Poznan's district have taken part in the research. Paramedics with higher SPS results were selected, creating a highly sensitive people (HSP) group.
Results:
: When non-HSP people were compared to paramedics from the HSP group, an emergency signal was considered more burdensome for HSP paramedics. The intensity of noise generated by the vehicle's suspension elements and tires was significantly higher in cars more than 3 years old. Older paramedics (≥30 years old) evaluated the intensity as well as burdensomeness of noise generated by suspension's elements and tires, higher than the younger (<30 years old) ones.
Conclusions:
: Both paramedics and drivers as occupational groups are liable to noise, which seems to be particularly harmful and burdensome to the HSP group. Further studies should be provided in this area. This may lead to an increase not only in their productivity but also in their quality of life.

Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
