What is one contraindication for using CPAP?

A contraindication for using Continuous Positive Airway Pressure (CPAP) is a decreased level of consciousness. CPAP requires the patient to be able to maintain their own airway effectively. When a patient has a decreased level of consciousness, their ability to protect their airway diminishes significantly, increasing the risk of airway obstruction or aspiration.

In situations where the patient's level of consciousness is impaired, the ability to respond to respiratory distress and manage secretions becomes compromised. This can lead to serious complications, making the application of CPAP dangerous for that patient. Therefore, it is crucial to assess the patient’s neurological status before initiating CPAP therapy.

On the other hand, pulmonary edema and respiratory distress from COPD may benefit from CPAP usage, as it can help improve oxygenation and reduce work of breathing. The ability to maintain the airway is also a separate consideration, as patients who can maintain their own airway may be suitable candidates for CPAP.
