Study summary

  • Assessment of diaphragmatic function (excursion, thickness variation, thickness ratio) in COPD and bronchial asthma patients.
  • Assessment of presence of correlation between diaphragmatic dysfunction and pulmonary function.
  • Assessment of possible association between diaphragmatic dysfunction and presence of reversibility in pulmonary function post bronchodilator.

What researchers measure

Primary outcomes

  1. diaphragmatic function

    Compare diaphragmatic function using ultrasound device by measuring diaphragmatic thickness in both stable COPD and bronchial asthma patients.

    Time frame: 2 years

Secondary outcomes

  1. pulmonary function .

    assess the degree of effect of diaphragmatic dysfunction on pulmonary function measured by spirometry FEV1/FVC (forced expiratory volume1/ forced Vidal capacity )

    Time frame: 2 years
