Pulmonary function testing (PFT) is used in a variety of ways at Holy Family Hospital at Merrimack Valley in Haverilll. PFT can be used to establish baseline lung function, evaluate respiratory impairment, and evaluate operative risk. PFT can also be used in conjunction with smoking cessation classes.
PFT is often performed to diagnose certain types of lung disease (especially asthma, bronchitis and emphysema) and to determine the cause of shortness of breath. PFT can be used to monitor the effects of therapies used to treat respiratory disease, for example, it can also be used after the administration of medications, such as a bronchodilator to assess their effect and to measure progress in disease treatment.
PFT may be used to screen for lung function problems prior to employment in companies where employees use respirators or to measure whether occupational exposure to contaminants affects lung function, perform surveillance for occupational-related lung disease and screen for disability.
In addition, PFT may be used in conjunction with other test to effectively predict intraoperative and postoperative morbidity and mortality from pulmonary complications, the forced expiratory volume in one second (FEV1) obtained from spirometry is a useful tool. Operative risk is heavily dependent on the surgical site, with chest surgery having the highest risk.
Patient-related factors associated with increased operative risk for pulmonary complications include preexisting pulmonary disease, cardiovascular disease, pulmonary hypertension, dyspnea upon exertion, heavy smoking history, respiratory infection, cough (particularly productive cough) and advanced age.
The ATS has published guidelines for a standardized technique that includes spirometer performance standards. All pulmonary function testing performed at Holy Family Hospital at Merrimack Valley meets ATS guidelines.
