Mostmasks are made of clear, pliable plasticor rubber that can be molded to fit thefacePurposes:Nasal Cannula1.To prevent or reduce hypoxia. A nasalcannula is an effective mechanisms foroxygen delivery. It allows the client tobreathe through the mouth or nose; it isavailable for all age groups, and isadequate for short term or long-term use.Cannulas are inexpensive, disposable,generally comfortable and are easilyaccepted by most clients.2.To deliver low-concentration andmedium-concentration oxygenconcentrations (O’Discoll et al. 2017)3.To allow uninterrupted delivery ofoxygen while the client ingests food orfluids.Oxygen Mask1.To provide moderate 02 support and ahigher concentration of oxygen and/ orhumidity than is provided by cannula.The mask may deliver a highconcentration of oxygen (>50%) and istherefore not recommended for patientswho require low concentration oxygentherapy because of the risk of carbondioxide retention (O’Discoll et al. 2017).2.The mask is suitable for patients withrespiratory failure without hypercapnia(type 1 respiratory failure) but is notsuitable for patients with hypercapnic(type 2) respiratory failure.Equipment:Oxygen-delivery device as ordered bypatient’s health care providerOxygen tubing (consider extension tubing)Humidifier (if indicated) with steriledistilled waterOxygen sourceOxygen flowmeter connected to oxygensupplyStethoscope, pulse oximeterGauze to pad elastic band (optional)Personal Protective Equipment (PPE) asindicatedAppropriate room signs (e.g., no smoking,flammable, oxygen in use)Assessment1.Assess the patient’s oxygen saturationlevel before starting oxygen therapy to
