Exercise in Chronic Pulmonary Disease: limitations and rehabilitation.
Medicine and Science in Sports and Exercise, 2001Co-Authors: Christopher B. CooperAbstract:COOPER, C. B. Exercise in Chronic Pulmonary Disease: limitations and rehabilitation. Med. Sci. Sports Exerc., Vol. 33, No. 7, Suppl., pp. S643-S646, 2001. Chronic Pulmonary Disease is common in the community and increasing in prevalence. Although numerous etiologies exist, Chronic obstructive Pulmonary Disease secondary to tobacco smoking, and asthma constitute the majority of cases. The important impact of these Diseases on patients is disabling breathlessness and impairment of functional exercise capacity. The symptoms set up a vicious cycle leading to physical deconditioning and worsening exercise performance. The discipline of Pulmonary rehabilitation has been conclusively shown to reverse this process, resulting in improved functional capacity and reduced breathlessness. Pulmonary rehabilitation, therefore, should be viewed as essential secondary preventative care for the majority of patients with Chronic Pulmonary Disease. As such, early Disease recognition and implementation of exercise reconditioning is important. In order to be maximally effective, Pulmonary rehabilitation must recognize the complex underlying pathophysiology in Chronic Pulmonary Disease and he customized to the individual patient. The chosen mode of exercise training should recognize that in order to be truly beneficial, any physiological responses need to translate readily into improvements in activities of daily living. Therefore, sessions in Pulmonary rehabilitation should concentrate on exercises that have proven useful in this regard. Aerobic and resistance exercise prescriptions should he rigorous, scientifically based, and derived from an understanding of the basic principles of the human response to exercise prescription. Each of these exercise prescriptions should encompass the basic principles of intensity, frequency, duration, and progression suitably modified for the individual patient with Chronic Pulmonary Disease.

Determining the role of exercise in patients with Chronic Pulmonary Disease.
Medicine and science in sports and exercise, 1995Co-Authors: Christopher B. CooperAbstract:ABSTRACT Chronic Pulmonary Diseases are common in the community and their pathophysiology is complex. The principal symptoms are dyspnea and limited exercise capacity. Some, but not all, patients have true ventilatory limitation where the maximal exercise ventilation (VEmax) equals the measured maximal ventilatory volume (MVV). Those with obstructive Disease have impeded expiration requiring an obligatory expiratory time for adequate lung emptying (i.e., a timing constraint). In these patients, increased breathing frequency during exercise tends to lead to hyperinflation and smaller tidal volumes, circumstances that predictably worsen breathing efficiency (i.e., result in high VD/VT). Those with restrictive Disease characteristically have limited inspiratory capacity but-unimpeded or even accelerated expiration (i.e. tidal volume constraint). These patients characteristically exhibit rapid respiratory rates (e.g., >50-min−1) at end exercise.

The study on noninvasive evaluation of Pulmonary artery pressure by the method of Pulmonary artery flow spectrum in Chronic Pulmonary Disease
Chinese Journal of Tuberculosis and Respiratory Diseases, 1996Co-Authors: Wang G, Liu H, Yang WAbstract:Pulmonary artery flow spectrum of patients with Chronic Pulmonary Disease were studied in order to find excellent Doppler Indexes reflected Pulmonary artery pressure, and establish multiple regression equation for estimating Pulmonary artery pressure more accurately. During catheterization, 54 patients with Chronic Pulmonary Disease were examined by echocardiography. Fourteen Doppler indexes of spectrum were compared with the Pulmonary artery pressure by catheter simultaneously, and multiple regression equations were taken. There were significant correlation between Doppler indexes PEP/AcT, AcVm, VI/(QTxVmax), RVET/QT and Pulmonary artery pressure. Two multiple regression equations were deduced: PAPs (kPa) = [9.4 x PEP/AcT-1.4 x AcVm-126.1 x VI/(QT x Vmax) + 75] divided by 7.5 and PAPm (kPa) = [7.5 x PEP/AcT-1.2 x AcVm- 87.7 x VI/(QT X Vmax) + 48] divided by 7.5. Above two regression equations could be used to noninvasively evaluate Pulmonary artery pressure in patients with Chronic Pulmonary Disease.

The application of non-invasive and invasive mechanical ventilation in the first episode of acute respiratory failure
Internal and Emergency Medicine, 2020Co-Authors: Cheng-chi Huang, Tain-fung Wu, Te-chun Shen, Te-chun Hsia, Chuen-ming ShihAbstract:Acute respiratory failure (RF) is a life-threatening syndrome. This study investigated the application of two major clinical strategies, non-invasive mechanical ventilation (NIV) and invasive mechanical ventilation (IMV), in the first episode of acute RF. Data from the longitudinal health insurance database, which included 1,000,000 insured citizens, were used. The NIV group consisted of 1201 patients and the IMV group consisted of 16,072 patients. Chi-square test and t test were applied to determine the differences in categorical and continuous variables. Further analysis was performed by using univariate and multivariable logistic regression and Poisson regression. There was a significant increase of 733% in the number of NIV users from 2000 to 2012. NIV use was frequently observed in old-age persons (aOR 3.99, 95% CI 3.06–5.21 for those aged ≥ 80 years), women (aOR 1.33, 95% CI 1.18–1.50), patients admitted to a high-level hospital (aOR 1.95, 95% CI 1.63−2.34 for those admitted to a medical center), and patients with a higher Charlson comorbidity index (CCI, aOR 1.38−1.66 for those CCI ≥ 2). In addition, patients with Chronic Pulmonary Disease, cancer, and congestive heart failure were predominant in NIV users and were significantly associated with NIV use. Overall, the use of NIV has markedly increased over the past few years. Persons of advanced age, women, patients admitted to a high-level hospital, and patients with multiple comorbidities were associated with more frequent NIV use. Chronic Pulmonary Disease, cancer, and congestive heart failure were most important comorbidities for NIV use.

borderline Pulmonary hypertension associated with Chronic hypercapnia in Chronic Pulmonary Disease
Respiratory Physiology & Neurobiology, 2019Co-Authors: Liu Zuoyou, Satomi Shiota, Yoshiteru Morio, Ai Sugiyama, Mitsuaki Sekiya, Shinichiro Iwakami, Hiroki Ienaga, Yoshinosuke Fukuchi, Kazuhisa TakahashiAbstract:Abstract Pulmonary hypertension (PH) due to lung Diseases is classified as group 3 by the Dana Point classification. Given the basic pathophysiological conditions of group 3 lung Diseases and the previously well-known concept of hypercapnic Pulmonary vasoconstriction, Chronic hypercapnia besides alveolar hypoxia might be another causative factor to increase mean Pulmonary arterial pressure (PAm). Two hundred twenty-five subjects with Chronic Pulmonary Diseases were assessed by a right heart catheterization and blood gas parameters. The subjects were classified into the following 4 groups: Hypercapnic Hypoxia (HCHX), Hypercapnic Normoxia (HCnx), Normocapnic Hypoxia (ncHX), and Normocapnic Normoxia (ncnx). Compared with ncnx, the HCHX, HCnx and ncHX groups all showed significantly higher PAm and met the criteria of borderline PH. Multiple regression analysis showed that PaCO2, as well as SaO2, was an independent variable for PAm. Given the poor prognosis with borderline PH, the elimination of excess Pulmonary carbon dioxide in hypercapnia could be a considerable treatment strategy in Chronic Pulmonary Disease.
