Thanks for your query
Sudden fainting and stoppage of breathing in aknown COPD patient is indicative of some underlying complication specially pulmonary arterial hypertension or pulmonary embolism. Again your mom had a bed snore in this 70 years of age and in this case we need to exclude obstructive sleep apnea. Therefore i asked you to consult a pulmonologist, get locally examined and go through the following sets of investigations -
1. chest x-ray (PA view)
2. ECG
3. Echocardiography with spl focus to measure the mean pulmonary artery systolic pressure (PASP) to exclude PAH
4. CT angiography
5. Polysomnography
6. Lipid profile
Also ask the pulmonologist to check the inhaler technique and to assess the control of COPD.
Thank you.
