CPAP machine is routinely used during nights to treat obstructive sleep apnea
(OSA). This machine provides aid to the patient in breathing and provides oxygen
. Generally it is a safe treatment, free of any significant side effects. So, the palpitations are not likely to be due to CPAP. It would be better for you to consult your cardiologist. One may need to exclude a cardiac arrhythmia
(rhythm abnormality of the heart).
