Key result
Smoking two nicotine cigarettes is associated with increased HR and BP, and decreased peripheral flow.
Why the study?
Haemodynamic changes in finger skin blood flow after smoking cigarettes were monitored to assess reproducibility and correlation of thermography and laser-Doppler flowmetry methods.
Does smoking two 1.1 mg nicotine cigarettes reduce finger skin blood flow and temperature in smokers?
Population

Comparison

Acute smoking effects on skin perfusion are detectable by thermography; hypothesis-generating and should not yet change practice.

Does smoking two 1.1 mg nicotine cigarettes reduce finger skin blood flow and temperature in smokers?
Smoking acutely decreases peripheral skin blood flow, which can be reproducibly monitored using thermography and laser-Doppler flowmetry.
Bornmyr et al. (1991) conducted an observational in Smokers (n=24). Cigarette smoking was evaluated on Changes in heart rate, arterial blood pressure, finger temperature, and finger skin blood flow. Smoking two 1.1 mg nicotine cigarettes increased heart rate and arterial blood pressure, and decreased finger temperature and skin blood flow in 24 smokers.
