Which device options can be utilized for oxygen delivery in heart failure patients?

The option that includes facemask and CPAP is the most suitable for oxygen delivery in heart failure patients, primarily due to the need for effective oxygenation in these individuals, especially during exacerbations.

Facemasks provide a higher concentration of oxygen compared to nasal cannulas, making them useful in cases where patients require more support. Continuous Positive Airway Pressure (CPAP) is especially beneficial for heart failure patients, particularly those suffering from obstructive sleep apnea or acute pulmonary edema. CPAP helps maintain airway patency and improves oxygenation by preventing alveolar collapse during expiration.

Other methods like nasal cannulas can deliver supplemental oxygen but may not be adequate for patients in more severe distress or those requiring higher oxygen flow rates. While hooded oxygen devices can provide a gentle and non-invasive approach to oxygen therapy, they are less common in practice compared to facemasks and CPAP for heart failure management. Inhalers are generally used for delivering bronchodilators rather than for systematic oxygen delivery, so they do not serve the primary purpose of addressing hypoxia in heart failure patients.
