Smoke contains a mixture of harmful gases, chemicals, and superheated particles. Inhalation of smoke causes generalized hypoxia and airway inflammation due to impaired oxygen transport and utilization, as well as thermal and chemical injury in the airways. Generally, treatment is supportive with oxygen therapy and airway management, including chest physiotherapy, bronchodilators, and nebulization. Immediate oxygen therapy is mandatory for all suspected smoke inhalation patients and should not be delayed pending diagnostic test results or due to "normal" oxygen saturation readings that can be falsely elevated in carbon monoxide intoxication. Smoke inhalation patients with mild clinical signs who respond well to initial stabilization generally have a favorable prognosis. However, patients with severe signs or progression despite initial stabilization may require more advanced or intensive care.

Grenfell Tower Fire: Firefighters' Activities and Their Exposure to Fire Smoke and Heat.
J Occup Environ Med
January 2025
From the Centre for Fire and Hazards Sciences, University of Central Lancashire, Preston, Lancashire, United Kingdom.
Objective: This study aimed to characterize the smoke exposure of firefighters who attended the Grenfell Tower fire during the initial 20 hours.
Methods: As no compilation of exposure data exists, data were compiled from nine unconnected sources, including the Grenfell Tower Inquiry, firefighters' statements, incident logs, and the UK Firefighter Cancer and Disease Registry.
Results: Of the 628 firefighters who attended, information was available from 524.
Inhalation of patchouli essential oil alleviates airway inflammation in cigarette smoke-induced COPD mice.
Sci Rep
December 2024
State Key Laboratory of Biobased Material and Green Papermaking, School of Bioengineering, Qilu University of Technology, Shandong Academy of Sciences, Jinan, People's Republic of China.
Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide, characterized by persistent respiratory symptoms and airflow limitations resulting from small airway injury, bronchial wall thickening, and hypersecretion of mucus. Current pharmacological interventions are ineffective in reversing these airflow limitations; In our study, we investigated the potential role of patchouli essential oil (PEO) in the treatment of COPD and its underlying molecular mechanisms, both in vitro and in vivo. To establish a cigarette smoke-induced COPD mice model, we exposed the mice to cigarette smoke (CS) and administered nasal drip of lipopolysaccharides (LPS).

Department of Respiratory Medicine, The First Affiliated Hospital of Anhui University of Chinese Medicine, 230031 Hefei, Anhui, China.
Background: Chronic obstructive pulmonary disease (COPD) is a prevalent yet manageable respiratory condition. However, treatments presently used normally have side effects and cannot cure COPD, making it urgent to explore effective medications. The ginsenoside Rg3 (Rg3) has been shown to have anti-inflammatory and anti-tumor properties and can improve COPD.

Background: Various studies have explored the potential association between incense burning and the risk of lung cancer. However, the findings from these studies have been inconsistent.
Objectives: This study aimed to provide a more comprehensive understanding of the relationship between incense burning and lung cancer risk in the Asian population through a meta-analysis.
TRPA1 contributes to respiratory depression from tobacco aerosol.
Respir Physiol Neurobiol
December 2024
Department of Physiology, Graduate School of Medical and Dental Sciences, Kagoshima University, Kagoshima, Japan. Electronic address:
Transient receptor potential ankyrin-1 (TRPA1) is expressed in the trigeminal nerves in the nasal cavity. It detects irritant chemicals such as formalin and acrolein, induces respiratory depression to protect against further inhalation, and elicits avoidance behavior. Although tobacco smoke contains formalin, acrolein, and other irritant chemicals, the possible contribution of TRPA1 to protection against tobacco smoke has yet to be fully understood.
