Uncertainties in the expected value for forced expiratory volume in one second after surgery.

چکیده
The purpose of this study is to understand better the reasons for the frequent unreliability of the expected value for the forced expiratory volume in one second (FEV1) in predicting surgical results after pneumonectomy. Measurement of FEV1 was performed in 159 patients before and after removal of one lung. Only 41 of the postoperative values for FEV1 differed from predicted values by less than 5 percent. The reason for the discrepancy can be technical, resulting either from the method used to assess the functional pulmonary distribution (bronchospirometry or isotopic procedure) or from the data used to calculate predicted FEV1. The discrepancy can also depend on the patient himself and particularly on the possibilities of the remaining lung to expand normally after surgery. Follow-up of patients confirmed the clinical and functional effects of erroneous predicted FEV1.

Cromolyn sodium, a mast cell stabilizing agent, provides an immediate protective effect against the exercise-induced bronchoconstriction while being used before the exercise. However, cromolyn is ineffective in reversing asthmatic bronchospasm; it is used as a maintenance therapy and has a prophylactic role in chronic asthma. The purpose of this study was to determine the extent of change...

Background and Objectives: Idiopathic pulmonary fibrosis (IPF) is characterized by progressively worsening lung function, ventilation capacity, dyspnea, and finally reduced exercise intolerance. All of these have a significant negative impact on functional capacity and quality of life. In this study, we aim to evaluate the effects of pulmonary rehabilitation (PR) in IPF and assess the predictor...
