While the patient is breathing normally into the spirometer he is instructed to make a deep expiration. It is important to ensure the maximal possible emptying of the lung so that all the reserve (supplemental) air will be expelled into the spirometer. To achieve this the subject must be stimulated to go on expelling air until the expiratory line flattens out. This process is repeated once or t...

Background: Stroke is the leading cause of death and disability worldwide. It a cerebrovascular disease, characterized by decreased blood supply to brain tissues. known that patients with stroke have respiratory muscle weakness. Aim: To evaluate effects Resistive Diaphragmatic Breathing Exercises on pulmonary functions in chronic stroke. Method: A randomized controlled trial was conducted. 20 s...

Incentive spirometry is one of the most common methods used for respiratory rehabilitation in early period after cardiac surgery. Inspiratory capacity values, obtained by a patient using spirometer, are not reliably trusted. Objectives. To compare volumetric parameters measured with incentive spirometer and results bedside ultrasound-based to assure feasibility use assess inspiratory e?ectivene...

BACKGROUND Long-term cohort studies and lung function laboratories are confronted with the need for replacement of spirometers. Lack of agreement between spirometers might affect the longitudinal comparison of data, notably when replacing conventional by portable spirometers. OBJECTIVES To compare the handheld EasyOne (EO) with the conventional SensorMedics (SM) spirometer, and to analyze the...

BACKGROUND A study was undertaken to test the long term performance of a small hand held spirometer for self-administered serial spirometric testing. METHODS Thirty turbine pocket spirometers (MicroMedical DiaryCard) were used in a clinical trial on 22 emphysematous patients with severe alpha 1-antitrypsin deficiency. The spirometers were able to store the date, time, forced expiratory volume...

Respiratory magnetometers are increasingly being used in sleep studies to measure changes in end-expiratory lung volume (EELV), including in obese obstructive sleep apnea patients. Despite this, the accuracy of magnetometers has not been confirmed in obese patients nor compared between sexes. Thus we compared spirometer-measured and magnetometer-estimated lung volume and tidal volume changes du...
