Summary
Introduction:
This text provides a comprehensive analysis of the effects of electronic cigarette (e-cigarette) inhalation on lung function compared to non-e-cigarette use. The study also examines self-changes in lung function after inhaling e-cigarettes. The text is based on a systematic review of relevant literature from four databases and follows the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMa) guidelines.
Key Points:
* The study found that short-term e-cigarette inhalation has a similar (but not significant) effect on lung function compared to non-e-cigarettes.
* CO and FeNO were significantly decreased after e-cigarette usage.
* Only asthmatic smokers showed a statistically significant increase in flow resistance after inhaling e-cigarettes.
* The degree of O2 saturation decrease was less than that for the cigarette groups, especially when compared to the conventional cigarette group.
* The decrease of FEV1/FVC% in the non-e-cigarette groups exceeded that in the e-cigarette group.
* Lung-function assessment showed no significant change in pulmonary ventilation measures within 1 month of inhalation of e-cigarettes compared to pre-inhalation.
* The study included 18 articles, most of which had comparatively few participants.
Main Message:
The study suggests that short-term e-cigarette inhalation has a similar (but not significant) effect on lung function compared to non-e-cigarettes. however, more clinical studies are needed to explore the safety of inhaling e-cigarettes, especially in vulnerable populations. The long-term effects of e-cigarette inhalation on lung function are still not well understood and require further investigation.
