CPAP Circuits

• Continous Positive Airway Pressure (CPAP) is the method of ventilating a patient applying higher pressure than environmental atmospheric pressure to the airways of the patient to improve oxygenation via ventilator or CPAP machine
• CPAP prevents early end-expiratory closure of the airways and alveolar collapse
• Today CPAP is routinely used for mechanically ventilated patients or spontaneously breathing respiratory patients to improve the oxygenation

CPAP Indications

• Obstructive sleep apnea syndrome, ARDS, Post-operative atelectasis
• Acute respiratory distress, COPD, Cardiogenic pulmonary oedema
• Post-extubation hypoxemia, weaning
