Peak inspiratory flow through Turbuhaler in acute asthma.
Efficient use of dry powder inhalers, such as Turbuhaler, is dependent on the generation of adequate inspiratory flow. It is not clear whether patients with acute asthma are able to generate adequate flow. Peak inspiratory flow (PIF) was measured through an empty Turbuhaler, and without this device, in 99 adults presenting to hospital with acute exacerbations of asthma. Where possible, patients...
متن کاملInspiratory muscle training may increase peak inspiratory flow in chronic obstructive pulmonary disease.
BACKGROUND When choosing a specific inhalation device for a chronic obstructive pulmonary disease (COPD) patient, the internal airflow resistance and the ability of the patient to overcome it and to create an optimal inspiratory flow are essential. OBJECTIVES The purpose of the present study was to investigate: (1) the peak inspiratory flow (PIF) that a patient with COPD can generate while br...
متن کاملThe impact of inspiratory effort on inspiratory flow through Turbuhaler in asthmatic patients.
To investigate the impact of the inhalation effort on the peak inspiratory flow through Turbuhaler, 100 asthmatics having a wide range of asthma severity (baseline forced expiratory volume in one second 28-127% of predicted normal) were studied. Each patient inhaled through four modifications of empty Turbuhaler inhalers, using first a "deep" inhalation and then a "forceful and deep" inhalation...
متن کاملPotassium studies in chronic obstructive airways disease.
Seventeen male patients with chronic obstructive airways disease in remission were separated into two groups according to arterial carbon dioxide tensions. Hypercapnia was associated significantly with hypoxia and increased red cell volume whereas normocapnia was not. Normocapnic patients were significantly lighter than those with hypercapnia. Total body potassium (TBK) measured by the whole bo...
متن کاملDisease of the airways in chronic obstructive pulmonary disease.
The pathological hallmarks of chronic obstructive pulmonary disease (COPD) are inflammation of the small airways (bronchiolitis) and destruction of lung parenchyma (emphysema). The functional consequence of these abnormalities is airflow limitation. Airway abnormalities and emphysema interact in a complex fashion in the development of airflow limitation in COPD. In an attempt to improve underst...
