Interventions for Clients Requiring Oxygen Therapy or Tracheostomy

The goal of oxygen therapy is to use the lowest fraction of inspired oxygen (FiO2) to obtain the most acceptable oxygenation without causing the development of harmful side effects The goal of oxygen therapy is to use the lowest fraction of inspired oxygen (FiO2) to obtain the most acceptable oxygenation without causing the development of harmful side effects The average client requires an oxygen flow of 2 to 4 L/min via nasal cannula or up to 40% via Venturi mask. The average client requires an oxygen flow of 2 to 4 L/min via nasal cannula or up to 40% via Venturi mask. The client who is hypoxemic and also has chronic hypercarbia (increased partial pressure of arterial carbon dioxide [PaCO2] levels) requires lower levels of oxygen delivery, usually 1 to 2 L/min via nasal cannula, to prevent decreased respiratory effort. (A low PaO2 level is this client's primary drive for breathing.

Low-flow oxygen delivery systems NASAL CANNULA. The nasal cannula, or nasal prongs, is used at flow rates of 1 to 6 L/min. Approximate oxygen concentrations of 24% (at 1 L/min) to 44% (at 6 L/min) can be achieved. NASAL CANNULA. The nasal cannula, or nasal prongs, is used at flow rates of 1 to 6 L/min.

The nurse places the nasal prongs in the nostrils, with the openings facing the client

Low-flow oxygen delivery systems SIMPLE FACE MASK. A simple face mask is used to deliver oxygen concentrations of 40% to 60% for short-term oxygen therapy or in an emergency. A minimum flow rate of 5 L/min is needed to prevent the rebreathing of exhaled air. The nurse gives special attention to skin care and to the proper fitting of the mask so that inspired oxygen concentration is maintained SIMPLE FACE MASK. A simple face mask is used to deliver oxygen concentrations of 40% to 60% for short-term oxygen therapy or in an emergency. A minimum flow rate of 5 L/min is needed to prevent the rebreathing of exhaled air. The nurse gives special attention to skin care and to the proper fitting of the mask so that inspired oxygen concentration is maintained

Low-flow oxygen delivery systems PARTIAL REBREATHER MASK. A partial rebreather mask provides oxygen concentrations of 60% to 75%, with flow rates of 6 to 11 L/min. It consists of a mask with a reservoir bag but no flaps. The client first rebreathes one third of the exhaled tidal volume, which is high in oxygen, thus providing a high fraction of inspired oxygen (Fio2). PARTIAL REBREATHER MASK. A partial rebreather mask provides oxygen concentrations of 60% to 75%, with flow rates of 6 to 11 L/min. It consists of a mask with a reservoir bag but no flaps. The client first rebreathes one third of the exhaled tidal volume, which is high in oxygen, thus providing a high fraction of inspired oxygen (Fio2). The nurse ensures that the bag remains slightly inflated at the end of inspiration; otherwise, the client will not be getting the desired oxygen prescription. If needed, the nurse calls the respiratory therapist for assistance The nurse ensures that the bag remains slightly inflated at the end of inspiration; otherwise, the client will not be getting the desired oxygen prescription. If needed, the nurse calls the respiratory therapist for assistance

Low-flow oxygen delivery systems NON-REBREATHER MASK. A non- rebreather mask provides the highest concentration of the low-flow systems and can deliver an Fio2 greater than 90%, depending on the client's breathing pattern. The non-rebreather mask is used most often with deteriorating respiratory status who might soon require intubation. NON-REBREATHER MASK. A non- rebreather mask provides the highest concentration of the low-flow systems and can deliver an Fio2 greater than 90%, depending on the client's breathing pattern. The non-rebreather mask is used most often with deteriorating respiratory status who might soon require intubation. The non-rebreather mask has a one- way valve between the mask and the reservoir and two flaps over the exhalation ports. The valve allows the client to draw all needed oxygen from the reservoir bag, and the flaps prevent room air from entering through the exhalation ports. During exhalation, air leaves through these exhalation ports while the one-way valve prevents exhaled air from re-entering the reservoir bag.

During exhalation, air leaves through these exhalation ports while the one-way valve prevents exhaled air from re-entering the reservoir bag.

High-flow oxygen delivery systems VENTURI MASK. The Venturi mask (commonly called Venti mask) delivers the most accurate oxygen concentration. Its operation is based on a mechanism that pulls in a specific proportional amount of room air for each liter flow of oxygen. An adaptor is located between the bottom of the mask and the oxygen source. Adaptors with holes of different sizes allow only specific amounts of air to mix with the oxygen. Precise delivery of oxygen results. Each adaptor also specifies the flow rate to be used; for example, to deliver 24% of oxygen, the flow rate must be 4 L/min. Another type of Venturi mask has one adaptor with a dial that the nurse uses to select the amount of oxygen desired. Humidification is not necessary with the Venturi mask. The Venturi system is best for the client with chronic lung disease because it delivers a precise oxygen concentration VENTURI MASK.

Noninvasive positive-pressure ventilation Noninvasive positive-pressure ventilation (NPPV) is a newer technique using positive pressure to keep alveoli open and improve gas exchange without the need for airway intubation. Noninvasive positive-pressure ventilation (NPPV) is a newer technique using positive pressure to keep alveoli open and improve gas exchange without the need for airway intubation. This type of ventilation can deliver oxygen or may just use room air. Essentially, a nasal mask or full-face mask delivery system allows mechanical delivery of either bilevel positive airway pressure (BiPAP) or continuous nasal positive airway pressure. This type of ventilation can deliver oxygen or may just use room air. Essentially, a nasal mask or full-face mask delivery system allows mechanical delivery of either bilevel positive airway pressure (BiPAP) or continuous nasal positive airway pressure. For BiPAP, a cycling machine delivers a set inspiratory positive airway pressure each time the client begins to inspire. As the client begins to exhale, the machine delivers a lower set end expiratory pressure. Together, these two pressures improve tidal volume. For BiPAP, a cycling machine delivers a set inspiratory positive airway pressure each time the client begins to inspire. As the client begins to exhale, the machine delivers a lower set end expiratory pressure. Together, these two pressures improve tidal volume. Nasal continuous positive airway pressure delivers a set positive airway pressure continually throughout each cycle of inhalation and exhalation. The effect is to open collapsed alveoli. Clients who might benefit from this form of oxygen or air delivery include those with postoperative atelectasis or cardiac-induced pulmonary edema. This technique is also used for sleep apnea.

Transtracheal oxygen therapy Transtracheal oxygen (TTO) is a long-term method of delivering oxygen directly into the lungs. The physician passes a small, flexible catheter into the trachea via a small incision with the use of local anesthesia. Transtracheal oxygen (TTO) is a long-term method of delivering oxygen directly into the lungs. The physician passes a small, flexible catheter into the trachea via a small incision with the use of local anesthesia. TTO allows better compliance and avoids the irritation that nasal prongs cause. Clients also report it to be more cosmetically acceptable. TTO allows better compliance and avoids the irritation that nasal prongs cause. Clients also report it to be more cosmetically acceptable. A TTO team provides formal client education, including the purpose of TTO and care of the catheter. The physician prescribes a TTO flow rate for rest and for activity and a flow rate for the nasal cannula, to be used when the TTO catheter is being cleaned. The average client will have a 55% reduction in required oxygen flow at rest and a 30% decrease with activity A TTO team provides formal client education, including the purpose of TTO and care of the catheter.
