Brief summary
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.
Detailed description
This is a feasibility 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 adults asthma and COPD patients (age \>18) that arrive at the Emergency Department (ED). Patients will be enrolled on a continuous basis and will be monitored by a capnograph and an oximeter before, during and after lung function assessment and medical treatment.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Correlation between capnography parameters and severity of asthma | 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 |
