Elevated Co2 levels are an indication of breathing problems, such as emphysema, asthma or sleep apnea. Both CPAP and BiPAP are effective treatments for elevated Co2 levels. The cause of your elevated Co2 levels will determine which treatment is best.
CPAP delivers a predetermined amount of pressure continuously to keep your airway open. BiPAP delivers two levels of pressure, a higher amount when you inhale, and a smaller amount when you exhale.
CPAP is normally used in the treatment of elevated Co2 levels caused by sleep apnea, while BiPAP is often prescribed for people suffering from respiratory or cardiopulmonary diseases, in addition to sleep apnea. All of these problems cause elevated Co2 levels.
CPAP pressure settings and breathing mask can be adjusted to suit your needs. BiPAP is similar, except you can reduce the flow of oxygen to a predetermined level when you exhale.
Both CPAP and BiPAP machines are compact and portable, and can travel with you wherever you go.
CPAP and BiPAP side effects include headaches, runny nose, dizziness and indigestion.
The Best Choice
Both CPAP and BiPAP are effective breathing treatments for elevated Co2 levels, but most people prefer BiPAP because of the different pressure level settings for inspiration and expiration.
