Effects on vital signs after twenty minutes of vaping compared to people exposed to second-hand vapor.

Introduction:
This text provides an analysis of the physiological effects of vaping and exposure to second-hand vapor in a controlled experimental setting. The study compares the vital signs of participants who directly vaped and those who were exposed to vapor but did not use the vape device. The study also explores demographic differences between the two groups.

Key Points:

* The study used a mixed-factorial experimental design with one "between groups" factor (participants who directly vaped versus participants who did not directly vape but were exposed to second-hand vapor) and eight repeated measures of "within subjects" factors (measurements of each of the eight physiological variables both before and after vaping or exposure to second hand vapor).
* Participants were commingled in data gathering sessions such that non-vape participants were sat next to vape participants.
* Physiological variables measured included heart rate, respiratory rate, percent of blood oxygen saturation, blood pressure, pulmonary function tests, and blood sugar.
* The study found that both direct inhalation of vegetable glycerine and propylene glycol vapor through a vape device and inhalation of second-hand vapor by those not using a vape device but exposed to such vapor contributed to an increase in heart rate and blood pressure.
* however, there was no significant difference in blood oxygen saturation, respiratory rate, blood sugar, or pulmonary function tests between the two groups.
* The study also found that participants who directly vaped had a higher frequency of health risk factors, including alcoholism, use of alcohol, cigarette use, former cigarette use, and mental illness, compared to the non-vaping participants.

Main Message:
The study suggests that vaping and exposure to second-hand vapor can have immediate physiological effects, including an increase in heart rate and blood pressure. however, the study did not find any significant difference in blood oxygen saturation, respiratory rate, blood sugar, or pulmonary function tests between the two groups. additionally, participants who directly vaped had a higher frequency of health risk factors compared to the non-vaping participants. These findings highlight the need for further research on the potential health effects of vaping and the importance of considering individual health risk factors when evaluating the risks associated with vaping.
