Which nursing action best promotes adequate gas exchange in Pulmonary disease (COPD)?

Using a high-flow Venturi mask to deliver oxygen as prescribed

The client with COPD retains carbon dioxide, which inhibits stimulation of breathing by the medullary center in the brain. As a result, low oxygen levels in the blood stimulate respiration, and administering unspecified, unmonitored amounts of oxygen may depress ventilation. To promote adequate gas exchange, the nurse should use a Venturi mask to deliver a specified, controlled amount of oxygen consistently and accurately. Drinking three glasses of fluid daily wouldnt affect gas exchange or be sufficient to liquefy secretions, which are common in COPD. Clients with COPD and respiratory distress should be placed in high Fowlers position and shouldnt receive sedatives or other drugs that may further depress the respiratory center.
