Transtracheal catheter high flow, insert a catheter through a small incision directly into the trachea. It is indicated for patients with chronic oxygen therapy needs
1/4-4, 60-100, More comfortable, concealed by clothing, less oxygen liters per minute needed than nasal cannula
Requires frequent and regular cleaning, requires surgical intervention, with associated risk for surgical complications
110
Mask, Venturi, high flow, most reliable and accurate method for delivering precise concentrations of oxygen through noninvasive means.
(4-6, 24,26,28), (6-8, 30,35,40)Provides low levels of supplemental O2
Must remove to eat
Precise FiO2, additional
111
Mask, aerosol, high flow
8*10, 30-100, Good humidity, accurate FiO2
Uncomfortable for some
112
Tracheostomy collar, high flow
8-10, 30-100,
| Good humidity, comfortable, fairly accurate FiO2
113
T-piece, high flow, onnects to the endotracheal or tracheostomy tube and is useful in weaning patients from mechanical ventilation
8-10, 30-100, Same as tracheostomy collar
Heavy with tubing
114
Face tent, high flow
8-10,30-100, Good humidity, fairly accurate FiO2
Bulky and cumbersome
115
Oxygen-Conserving Devices, Pulse dose (or demand)
10-40ml/breath, Deliver O2 only on inspiration, conserve 50–75% of O2 used
Must carefully evaluate function individually
116
low-flow (variable performance)
the patient breathes some room air along with the oxygen
117
high-flow (fixed performance)
provide the total inspired air. A specific percentage of oxygen is delivered independent of the patient’s breathing. High-flow systems are indicated for patients who require a constant and precise amount of oxygen.
118
Hyperbaric oxygen therapy
treat conditions such as decompression sickness, air embolism, carbon monoxide poisoning, cyanide poisoning, smoke inhalation, gangrene, tissue necrosis, wound healing, skin grafts, refractory anaerobic infections, and refractory osteomyelitis , 100% o2
119
Patient teaching for oxygen therapy
patient is instructed to see their primary provider every 6 months or more often, if indicated. Arterial blood gas measurements and laboratory tests are repeated annually or more often if the patient’s condition changes.
120
Incentive spirometry
method of deep breathing that provides visual feedback to encourage the patient to inhale slowly and deeply to maximize lung inflation and prevent or reduce atelectasis. The purpose of an incentive spirometer is to ensure that the volume of air inhaled is increased gradually as the patient takes deeper and deeper breaths.
121
volume type, incentive spir
the tidal volume is set using the manufacturer’s instructions. The patient takes a deep breath through the mouthpiece, pauses at peak lung inflation, and then relaxes and exhales. Taking several normal breaths before attempting another with the incentive spirometer helps avoid fatigue. The volume is periodically increased as tolerated.
122
flow type, incentive spir
olume is not preset. The spirometer contains a number of movable balls that are pushed up by the force of the breath and held suspended in the air while the patient inhales. The amount of air inhaled and the flow of the air are estimated by how long and how high the balls are suspended.
Indications
123
Incentive spiro use
Incentive spirometry is used after surgery, especially thoracic and abdominal surgery, to promote the expansion of the alveoli and to prevent or treat atelectasis.
124
Nursing managemet for Incentive spiro
placing the patient in the proper position, educating the patient on the technique for using the incentive spirometer, setting realistic goals for the patient, and recording the results of the therapy (see Chart 21-3). Ideally, the patient assumes a sitting or semi-Fowler’s position to enhance diaphragmatic excursion; however, this procedure may be performed with the patient in any position.
125
Chest physiotherapy (CPT
postural drainage, chest percussion and vibration, and breathing retraining. In addition, educating the patient about effective coughing technique is an important part of CPT. The goals of CPT are to remove bronchial secretions, improve ventilation, and increase the efficiency of the respiratory muscles
126
Endotracheal intubation
The oral route is preferred since oral intubation is associated with less trauma and lesser rates of infection; furthermore, the oral route can typically accommodate a larger diameter
