Brief Summary

Title: Acute effects of waterpipe smoking (WPS) on cognitive measures and cardiorespiratory parameters Objectives: To evaluate the acute effect of one cession of water pipe smoking on:

  1. 1.executive functions which evaluated by cognitive tests administered included the digit span subtest Wechsler Adult Intelligence Scale (WAIS)-version III hebrew battery, and the Paced Auditory Serial Addition Test (PASAT)
  2. 2.Cardiorespiratory parameters included vital signs, spirometry parameters and lung clearance index (LCI) value
  3. 3.serum carboxyhemoglobin, nicotine, and cytokines

Outcome Measures

Primary Outcomes (1)

  • Primary outcome parameters were executive cognitive measures - The digit span test and Paced Auditory Serial Addition Test (PASAT)

    The digit span subtest Wechsler Adult Intelligence Scale (WAIS) version III hebrew battery. Participants hear digit sequences of increasing lengths and have to recall them forward and in reversed order. Each level contains two equal number series with different numbers. Higher values represent a better outcome. Maximus score is 30 points. Paced Auditory Serial Addition Test (PASAT) - Single digits are presented every 3 seconds and the participant must add each new digit to the one immediately prior to it. The score is the total number correct out of 60 possible answers. Higher values represent a better outcome. Maximus score is 60 points.

    Change from baseline immediately after 30 minutes of smoking

Secondary Outcomes (9)

  • Heart rate

    Baseline and immediately after 30 minutes of smoking

  • Respiratory rate

    Baseline and immediately after 30 minutes of smoking

  • Blood pressure - systolic and diastolic

    Baseline and immediately after 30 minutes of smoking

  • Oxygen saturation

    Baseline and immediately after 30 minutes of smoking

  • Pulmonary parameters - Lung clearance index (LCI)

    Baseline and immediately after 30 minutes of smoking

  • +4 more secondary outcomes
