condition of being wtithout oxygen
What is the most common cause of respiratory insufficiency?
obstruction of the airway
How are airway obstructions reversed?
positioning and suctioning
- decreased amount of oxygen in the blood stream
- may lead to hypoxia
reduced amount of oxygen available to meet cellular needs
too much carbon dioxide in the bloodg
What are the symptoms of hypoxia
- retractions (muscles move in during inspiration)
Patients suffering from hypoxia are susceptible to....
- respiratory infections due to insufficient inflation of the lungs
- secretions pool providing a growth medium for microorganisms
What does the pulse oximeter measure?
- changes in arterial oxygen saturation
- intravenous dye and jaundice reduce accuracy
- levels below 90% is a signal of hypoxia
What are the 2 standard methods of clearing secretions?
deep breathing and coughing
What is postural drainage
- placing the patient in different positions to clear secretions in different segments of the lungs
- each position should be done for 5 - 15 minutes
- use a nebulizer to help make secretions thinner
- ususally done in the AM 45 - 60 min before breakfast
What are the 5 different instruments used to deliver oxygen?
Which pieces of equipment are needed for oxygen therapy?
- oxygen source
- humidifier (optional)
- required appliance
What is the normal flow rate for administering oxygen?
- 2 - 5 L/min (pg520)
- 4 - 6 L/min (pg521)
What are the (4) purposes of an artificial airway
- relieve an obstruction
- protect teh airway
- facilitate suctioning
- provide artificial ventilation
Name the 2 types of pharyngeal airways
pharyngeal suctioning is required for
- gravely debilatated or unconcious
- pts with ineffective cough
