Administração de Oxigênio por Máscara

Gather a flow meter connected to an oxygen supply, a humidifier with sterile distilled water, an oxygen face mask, gauze pads, and Personal Protective Equipment (PPE). Assembling all equipment at the bedside conserves time and energy, making the procedure more efficient and preventing unnecessary delays during patient care.

Place the face mask over the patient's nose and mouth, then adjust the elastic strap to fit snugly but comfortably. If the patient reports irritation or redness, use gauze pads under the elastic strap at pressure points to reduce irritation to the ears and scalp. Proper positioning ensures effective oxygen delivery and patient comfort.

Humidification prevents mucous membrane dehydration, which can occur during oxygen therapy. Attaching the face mask to the oxygen source with humidification ensures the patient's airways remain moist and protected. This reduces discomfort and potential respiratory complications from dry air exposure.

Perform hand hygiene and wear PPE to prevent cross-infection. Ensure correct patient identification to prevent errors, close the door for privacy, and explain the procedure to promote cooperation and alleviate anxiety. These preparatory steps establish a safe, respectful environment and ensure the intervention targets the correct patient.

Remove the mask and dry the skin every 2 to 3 hours if oxygen runs continuously. Do not use powder around the mask, as it can interfere with the seal and cause irritation. Use gauze pads under pressure points to prevent skin breakdown. Regular assessment and maintenance reduce complications and improve patient tolerance.

Document the type of mask used, the amount of oxygen delivered, the patient's oxygen saturation level, lung sounds, and respiration patterns. Also note the patient's respiratory rate and effort, and any signs of respiratory distress. Thorough documentation provides a complete record of therapy effectiveness and guides future care decisions.

Face masks deliver oxygen at higher flow rates and concentrations than nasal cannulas, making them suitable for patients requiring more substantial supplemental oxygen. Understanding different oxygen delivering systems helps nurses select the appropriate device based on patient needs and prescribed oxygen requirements for optimal respiratory support.
