Smoker's home destroyed and neighbor injured
• Kalispell MO, 15 July 2004 A home on Kalispell's west side was extensively damaged Wednesday morning by a fire that was probably started by a cigarette and was accelerated by oxygen from medical oxygen tanks. A neighbor, who was trying to help was knocked down by the explosion of one oxygen tank, which also caused temporary hearing loss for a police officer.
• A report by F. Ray Ruffatto of the fire department's prevention division said that while the exact cause of the fire is still undetermined, "initial investigation indicates the fire may be the result of carelessly discarded smoking materials."

degree burns from a devastating blaze at her Manning Street home Sunday.
• The resident was a smoker, according to State Fire Marshal Stephen Coan, and he said the combination of cigarettes and the multiple oxygen tanks in the home either caused or exacerbated the fire.
• She was in critical condition after being pulled from the house by a neighbor and then died yesterday at UMass Memorial Medical Center, University Campus in Worcester.
• The combination of oxygen tanks and cigarettes have sparked fires that since 1997 have killed 16 people in the state and caused severe burns or smoke inhalation in 20, said Coan.

COPD - overview
COPD?– Chronic Obstructive Pulmonary Disease
• Broad classifications of disease
![Page 130: Respiratory Medical – Surgical Nursing P10B. Nasal Cavity Location – Btw mouth & cranium Function – Remove foreign bodies – Warm – Moisten – Olfactory.](https://reader035.fdocuments.net/reader035/viewer/2022062421/56649dbf5503460f94ab3978/html5/thumbnails/130.jpg)
COPD
• Characterized by – airflow limitation – Irreversible– Dyspnea on exertion– Progressive– Abn. inflammatory response of the lungs to
noxious particles or gases
![Page 131: Respiratory Medical – Surgical Nursing P10B. Nasal Cavity Location – Btw mouth & cranium Function – Remove foreign bodies – Warm – Moisten – Olfactory.](https://reader035.fdocuments.net/reader035/viewer/2022062421/56649dbf5503460f94ab3978/html5/thumbnails/131.jpg)
Pathophysiology
• Noxious particles of gas • Inflammatory response • Narrowing of airway
![Page 132: Respiratory Medical – Surgical Nursing P10B. Nasal Cavity Location – Btw mouth & cranium Function – Remove foreign bodies – Warm – Moisten – Olfactory.](https://reader035.fdocuments.net/reader035/viewer/2022062421/56649dbf5503460f94ab3978/html5/thumbnails/132.jpg)
Pathophysiology
• Inflammation • Thickening of the wall of the pulmonary
capillaries• (Smoke damage & inflammatory process)
![Page 133: Respiratory Medical – Surgical Nursing P10B. Nasal Cavity Location – Btw mouth & cranium Function – Remove foreign bodies – Warm – Moisten – Olfactory.](https://reader035.fdocuments.net/reader035/viewer/2022062421/56649dbf5503460f94ab3978/html5/thumbnails/133.jpg)
COPD
• Includes– Emphysema– Chronic bronchitis

COPD - FYI
• COPD 4th leading cause of death in the US• 12th leading cause of disability• Death from COPD is on the rise while death
from heart disease is going down
![Page 135: Respiratory Medical – Surgical Nursing P10B. Nasal Cavity Location – Btw mouth & cranium Function – Remove foreign bodies – Warm – Moisten – Olfactory.](https://reader035.fdocuments.net/reader035/viewer/2022062421/56649dbf5503460f94ab3978/html5/thumbnails/135.jpg)
COPD
Risk Factors for COPD• Exposure to tobacco smoke – 80-90% of COPD
• Passive smoking• Occupational exposure• Air pollution
![Page 136: Respiratory Medical – Surgical Nursing P10B. Nasal Cavity Location – Btw mouth & cranium Function – Remove foreign bodies – Warm – Moisten – Olfactory.](https://reader035.fdocuments.net/reader035/viewer/2022062421/56649dbf5503460f94ab3978/html5/thumbnails/136.jpg)
COPD risk factors
• #1– Smoking
• Why is smoking so bad??– ↓ phagocytes– ↓ cilia function– ↑ mucus production
![Page 137: Respiratory Medical – Surgical Nursing P10B. Nasal Cavity Location – Btw mouth & cranium Function – Remove foreign bodies – Warm – Moisten – Olfactory.](https://reader035.fdocuments.net/reader035/viewer/2022062421/56649dbf5503460f94ab3978/html5/thumbnails/137.jpg)
Chronic Bronchitis
• Disease of the airway• Definition:– cough + sputum production – > 3 months
![Page 138: Respiratory Medical – Surgical Nursing P10B. Nasal Cavity Location – Btw mouth & cranium Function – Remove foreign bodies – Warm – Moisten – Olfactory.](https://reader035.fdocuments.net/reader035/viewer/2022062421/56649dbf5503460f94ab3978/html5/thumbnails/138.jpg)
Chronic Bronchitis
Pathophysiology• Pollutant irritates airway • Inflammation• secretion of mucus
![Page 139: Respiratory Medical – Surgical Nursing P10B. Nasal Cavity Location – Btw mouth & cranium Function – Remove foreign bodies – Warm – Moisten – Olfactory.](https://reader035.fdocuments.net/reader035/viewer/2022062421/56649dbf5503460f94ab3978/html5/thumbnails/139.jpg)
Chronic Bronchitis
• Plugs become areas for bacteria to grow and chronic infections which increases mucus secretions and eventually, areas of focal necrosis and fibrosis
![Page 140: Respiratory Medical – Surgical Nursing P10B. Nasal Cavity Location – Btw mouth & cranium Function – Remove foreign bodies – Warm – Moisten – Olfactory.](https://reader035.fdocuments.net/reader035/viewer/2022062421/56649dbf5503460f94ab3978/html5/thumbnails/140.jpg)
Chronic Bronchitis
• Bronchial walls thicken– Bronchial Lumen narrows– Mucus plugs airway
• Alveoli/bronchioles become damaged• ↑ susceptibility to LRI
![Page 141: Respiratory Medical – Surgical Nursing P10B. Nasal Cavity Location – Btw mouth & cranium Function – Remove foreign bodies – Warm – Moisten – Olfactory.](https://reader035.fdocuments.net/reader035/viewer/2022062421/56649dbf5503460f94ab3978/html5/thumbnails/141.jpg)
