This is an observational study which aims to evaluate the possibility of using data from a capnography device to assess obstructive airway severity in both Chronic Obstructive Pulmonary Disease (COPD) and Asthma patients.

- Study Primary Completion Date: May 21, 2018
This is an observational study which aims to evaluate the possibility of using data from a capnography device to assess obstructive airway severity in both COPD and Asthma patients. The study will include adult asthma and COPD patients (age >18). Patients will be enrolled on a continuous basis and will be monitored by capnograph and oximeter before and after lung function assessment and also during and after medical treatment.
Arms, Groups and Cohorts
- Asthma and COPD patients
- Patients with COPD and Asthma. Continuous capnography and spirometry measurements of the subjects will be taken from the subjects with at least two minutes recording before the first spirometry assessment. All clinical diagnoses and treatments will be performed according to the department’s protocols. This is an observational study with no interventions
Clinical Trial Outcome Measures
- Correlation between capnography parameters and severity of asthma
- Time Frame: 1/2 hour to 48 hours from enrollment of subjects
- Correlation between the airway obstruction severity calculation based on the capnography parameters and the clinical severity of asthma and COPD as defined by forced expiratory volume in 1 second (FEV1), in severe asthma and COPD patients
