Oxygen is _______for life and a ________ used for _______and_________.
|
gas, drug, hypoxemia, hypoxia
|
|
|
Atmospheric air
|
21%
|
|
|
What is the goal of oxygen therapy?
|
to use the lowest fraction of inspired o2 to have acceptable blood 02 levels without causing harmful side effects
|
|
|
What is the best measure in monitoring the need for oxygen and evaluating it effects?
|
Arterial blood gas
|
|
|
A nonnvasive way to monitor o2 level
|
pulse oximetry
|
|
|
Pt with hypercarbia, and Co2 narcosis receiving o2 by mask or nalcannula
|
Monitor rate and depth of respirations q 2 hour
|
|
|
Pt with altered LOC or has a endotracheal tube
|
Use respirations precautions
|
|
|
Assesment pts receivng o2 by mask and naal cannula
|
assess skin undre mask and under plastic tubing every shift for patients receiving mask, assess nares and skin under elastic band for nc
|
|
|
Nursing diagnosis for pt recieving o2 therapy
|
May require a diagnois for anxiety and acute confusion related to hypoxemia and risk for impaired spontaneous ventilation
|
|
|
Oxygen therapy presents certain hazards and complication which includes
|
A risk for combustion
Oxygen induced hypoventilation, Oxygen toxicity related to o2 conc. delivered, duration of o2 therapy, degree of lung disease,absorption atelectasis from dilution of nitrogen levels and aveolar collapse, infection resultig fm nebulizers or other delivery equipment |
|
|
How are oxygen delivery systems classified?
|
by the rate of oxygen delivered
as low flow and high flow systems |
|
|
What are low flow delivery systems?
|
nasal cannula, simple face mask, partial rebreather mask, and non-rebreather mask :inexpensive, easy to use and fairly comfortable
|
|
|
How can oxygen be delivered in low flow systems?
|
oxygen is delivered is variable and depends on the pts breathing pattern since room air dilution occurs
|
|
|
High flow oxygen delivery system include
|
Venturi mask, aerosol mask, face tent, tracheostomy collar, and a T-piece which deliver accurate oxygen concentrations from 24% to 100% at 8 to 15 liters
|
|
|
Noninvasive positive-pressure ventilation
|
technique using posiive pressure to keep alveoli open and improve gas exchange without the need for airway intubation,using oxygen or just room air
|
|
|
A long term method in delivering oxygen directly into the lungs
|
Transtracheal oxygen deliver o2 direclty int the lungs through a small,flexible catheter passed ito the trachea via a small incision
|
