Continuous Positive Airway Pressure
Continuous Positive Airway Pressure device and consumables to support spontaneously breathing patients with respiratory failure.
What is CPAP?
“Continuous positive airway pressure (CPAP) is a type of positive airway pressure that is used to deliver a set pressure to the airways that is maintained throughout the respiratory cycle, during both inspiration and expiration.” [1] To keep the pressure constant in the breathing circuit, the flow rate should be at least equal to the patient’s peak inspiratory flow demand. This helps achieve Positive End Expiratory Pressure (PEEP). PEEP is achieved at the end of the expiratory breath by stenting the airways open enabling the lungs to remain inflated therefore stopping the collapse of the alveoli and maintaining sufficient air in the lungs.
Maintaining PEEP
Positive End Expiratory Pressure (PEEP) is used to maintain pressure on the lower airways at the end of the breathing cycle which prevents the alveoli from collapsing during expiration.
Increasing the surface area of the alveoli
The greater the surface area, the more gas exchange can occur therefore increasing the amount of oxygen in the blood.
Improving Oxygenation
By forcing the alveoli open and pushing oxygen across the alveolar membrane.
Frequently Asked Questions
Side effects of CPAP treatment may include congestion, runny nose or dry mouth, humidification can often help with these symptoms. Masks may cause irritation or redness of the skin from tight contact with skin.
