CPAP (Continuous Positive Airway Pressure) and BiPAP (Bilevel Positive Airway Pressure) are two forms of therapy used for individuals with sleep apnea or other respiratory conditions. While these therapies are similar, the two have a few key differences. Today, we will discuss the difference between CPAP and BiPAP therapies to give you a better understanding of what they are and when to use them.

CPAP and BiPAP Similarities

CPAP and BiPAP are both non-invasive respiratory support devices used to treat sleep apnea and other respiratory conditions. They are both forms of positive airway pressure (PAP) therapy. CPAP and BiPAP utilize a similar mask and hose system to deliver PAP therapy. They can both be used in a hospital or home setting. Both are versatile, as they can help treat various conditions.

CPAP and BiPAP Differences

The main difference between CPAP and BiPAP is that BiPAP therapy delivers two levels of air pressure, one for inhalation and one for exhalation. In contrast, CPAP therapy delivers a continuous single level of pressure.

CPAP

  • CPAP therapy is the most common treatment for obstructive sleep apnea (OSA), and it delivers a continuous, single level of air pressure. The constant air pressure helps keep the airway open and prevent apnea events throughout the night.
  • CPAP machines are a much more affordable option than BiPAP machines. CPAP machines are the ideal option for traveling as they are compact and affordable.
  • CPAP therapy is commonly used to treat less severe cases of sleep apnea and other mild respiratory conditions.
  • CPAP therapy can be less comfortable, and the adjustment period may be more extended for patients than BiPAP therapy because of the continuous level of air pressure that CPAP therapy provides.

BiPAP

  • BiPAP therapy delivers two different air pressure levels, called “bilevel.” A higher-pressure level is delivered during inhalation, and a lower pressure level is delivered during exhalation. These two pressure settings are inhalation-positive airway pressure (IPAP) and exhalation-positive airway pressure (EPAP).
  • The switch between these two levels can be timed on the machine and stays the same throughout the night (Fixed Setting) or automatically adjusted based on the user’s breathing patterns (Spontaneous Setting).
  • BiPAP machines can be more expensive than CPAP machines because of the additional settings and sensors. Sometimes, insurance companies will only cover the costs of a BiPAP machine once CPAP therapy has been found ineffective for the individual.
  • The two different pressure settings provide a more comfortable experience for the user and benefit individuals who require higher-pressure support.

Both CPAP and BiPAP therapy effectively treat sleep apnea and other respiratory conditions. Personal preference and severity of the condition will determine which option is better for you.
