The management of this 37-year-old male with post-surgical hypoxemia, significant smoking history, occupational exposures, and productive cough should prioritize supplemental oxygen, chest physiotherapy, and smoking cessation counseling, as these interventions address both immediate and long-term needs, particularly in reducing morbidity, mortality, and improving quality of life. Given the patient's significant smoking history (20 pack years) and occupational exposure to respiratory irritants, the risk of chronic bronchitis and COPD is high, as supported by studies such as 1, which emphasizes the role of smoking and environmental exposures in chronic cough due to chronic bronchitis. The patient's symptoms of cough with copious sputum production are consistent with chronic bronchitis, a condition often associated with smoking and occupational exposures, as noted in 1 and 1. Key management options include:
- Supplemental oxygen to maintain oxygen saturation above 92%
- Chest physiotherapy with postural drainage and incentive spirometry to clear secretions
- Smoking cessation counseling, with consideration of nicotine replacement therapy, varenicline, or bupropion, as smoking cessation is crucial in managing chronic bronchitis and reducing the risk of COPD, as suggested by 1
- Pulmonary function testing after recovery to evaluate for underlying COPD or other chronic lung disease
- Occupational health evaluation to address workplace exposures and implement protective measures, recognizing that occupational exposures can contribute significantly to chronic bronchitis and COPD, as discussed in 1 and 1. Empiric antibiotic therapy may be considered if there is suspicion of acute bronchitis or pneumonia, but this should be guided by clinical judgment and evidence of infection, as the routine use of pharmacologic treatments for chronic cough due to stable chronic bronchitis is not recommended without evidence of safety and efficacy, as stated in 1. Bronchodilator therapy with albuterol may be initiated to improve airflow, especially if there is evidence of bronchospasm or COPD. Overall, the management plan should be tailored to the patient's specific needs, with a focus on addressing both the acute hypoxemia and the underlying chronic respiratory condition, while also prioritizing interventions that improve morbidity, mortality, and quality of life, such as smoking cessation and management of occupational exposures.
From the FDA Drug Label
WARNINGS After proper administration of acetylcysteine solution, an increased volume of liquified bronchial secretions may occur. When cough is inadequate, the airway must be maintained open by mechanical suction if necessary. Where there is a mechanical block due to foreign body or local accumulation, the airway should be cleared by endotracheal aspiration, with or without bronchoscopy. Asthmatics under treatment with acetylcysteine solution should be watched carefully. Most patients with bronchospasm are quickly relieved by the use of a bronchodilator given by nebulization. If bronchospasm progresses, the medication should be discontinued immediately.
The management options for a 37-year-old male with hypoxemia post-hernia surgery, significant smoking history, occupational exposure to respiratory irritants, and symptoms of cough with copious sputum production may include:
- Monitoring: close observation of the patient's respiratory status, including oxygen saturation and lung function
- Bronchodilators: use of bronchodilators given by nebulization to relieve bronchospasm, as mentioned in the acetylcysteine label 2
- Airway management: maintenance of a patent airway, potentially with mechanical suction if necessary, to prevent complications from increased bronchial secretions
- Antibiotics: consideration of antibiotic therapy, such as levofloxacin 3, although the label does not provide specific guidance on this patient's condition Caution is advised when considering discharge, as the patient's respiratory status and potential for complications should be carefully evaluated.

Management Options for Hypoxemia Post-Hernia Surgery
The patient's history of smoking and occupational exposure to respiratory irritants, combined with symptoms of cough and copious sputum production, suggests a high risk for postoperative pulmonary complications 4. Considering the patient's low oxygen saturation, the following management options can be considered:
- Supplemental Oxygen Therapy: Administering supplemental oxygen can help improve oxygen saturation and reduce the risk of postoperative pulmonary complications 5, 6. However, it is essential to monitor the patient's oxygen saturation levels and adjust the oxygen therapy accordingly to avoid hyperoxia, which can have detrimental effects 7.
- Smoking Cessation: Encouraging the patient to quit smoking can help reduce the risk of postoperative pulmonary complications 4. Intensive smoking cessation programs can be effective in helping patients become permanent non-smokers.
- Respiratory Care: Implementing specific respiratory pre-operative interventions, such as deep breathing exercises and incentive spirometry, can help improve lung function and reduce the risk of postoperative pulmonary complications 4.
- Monitoring and Follow-up: Close monitoring of the patient's oxygen saturation levels and respiratory function is crucial to identify any potential complications early on. Regular follow-up appointments can help assess the patient's progress and adjust the management plan as needed.
Considerations for Discharge
Before discharging the patient, it is essential to ensure that their oxygen saturation levels are stable and within a safe range. The patient should also be educated on how to manage their respiratory symptoms and when to seek medical attention if their condition worsens. Additionally, considering the patient's history of smoking and occupational exposure, it may be beneficial to provide guidance on how to reduce their risk of future respiratory complications 4, 8.
