In which scenario would CPAP therapy be contraindicated?

In the context of CPAP (Continuous Positive Airway Pressure) therapy, it is crucial to consider the patient's hemodynamics, particularly blood pressure and overall stability. CPAP therapy can exacerbate hypotension due to a decrease in venous return to the heart because the positive pressure can impede blood flow. Therefore, in the scenario of a hypotensive patient with respiratory distress, administering CPAP could worsen the patient's condition by further lowering blood pressure, potentially leading to more serious complications.

In other situations, such as a confused but conscious patient with normal vital signs, a patient with clear lung sounds experiencing difficulty breathing, and a fully conscious and calm patient, the risks associated with CPAP are minimal when compared to the potential benefits. Each of these patients could potentially tolerate CPAP therapy without the added risk of exacerbating hypotension. Thus, when evaluating contraindications for CPAP therapy, the presence of hypotension in conjunction with respiratory distress clearly indicates that CPAP would not be appropriate.
