Transthoracic Ultrasonography Findings and Their Relation to Spirometric Indices in Patients With Obstructive and Restrictive Respiratory Diseases

Study Overview
=================
Brief Summary
-----------------
Evaluation of respiratory function is considered a crucial component in the assessment of patients with a wide range of respiratory diseases. Spirometry is considered a common method of measuring pulmonary function. Recently, Transthoracic ultrasound yields important diagnostic information within minutes. Respiratory muscle ultrasound is used to evaluate the anatomy and function of the respiratory system.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| normal people<br>people who don't complain of respiratory diseases will be examined by chest ultrasound and pulmonary function test. | Radiation: transthoracic ultrasonography<br>* lung ultrasonography Diaphragm and respiratory muscle ultrasound inferior vena cava ultrasound<br>Device: spirometry<br>* pulmonary function test : FVC, FEV1, FEV1/FVC will be measured.<br>|
| obstructive respiratory diseases<br>the patients who are diagnosed with either COPD or asthma. | Radiation: transthoracic ultrasonography<br>* lung ultrasonography Diaphragm and respiratory muscle ultrasound inferior vena cava ultrasound<br>Device: spirometry<br>* pulmonary function test : FVC, FEV1, FEV1/FVC will be measured.<br>|
| restrictive respiratory diseases<br>patient with either ILD | Radiation: transthoracic ultrasonography<br>* lung ultrasonography Diaphragm and respiratory muscle ultrasound inferior vena cava ultrasound<br>Device: spirometry<br>* pulmonary function test : FVC, FEV1, FEV1/FVC will be measured.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| investigate the correlation between transthoracic ultrasonography findings and their relation to spirometric indices in patients with different respiratory diseases. | we will study the degree of change in lung ultrasound, diaphragm, and respiratory muscles ultrasound, inferior vena cava ultrasound in obstructive and restrictive respiratory diseases .also, we find their correlation with spirometric indices in these diseases. | 6months |
