What does a stridor sound indicate and where does it come from?
Stridor sound often indicates an airway obstruction in the upper airway
Mild impairments in oxygenation can cause what?
- fatigue
- irritability
- discomfort
What are some things that can cause alterations in Gas exchange?
- COPD, emphysema
- CO2 retention
- Airflow in alveoli blocked by sputum, inflammation, atelectasis, or fluid volume excess
- blood flow in caps blocked by clots, plaque, and emphysemic alveoli
- airway patency
- moderate impairement
Define othropnea
difficulty breathing when supine
To determine if someone has orthopnea what question could you ask your patient?
How many pillows do you sleep with? Do you have to sleep in a recliner?
Define Kussmaul breathing
Deep, rapid exhalations increase the elimination of CO2, affecting the acid-base balance
Define Cheyne-strokes respirations
Deep, rapid breathing and slow, shallow breathing with periods of apnea
When do Cheyne-strokes respirations occur?
In CHF, increased intracranial pressure, and drug overdoses
Define Biot Respirations
Shallow breathing with periods of apnea. Occur in CNS disorders
What are some modifiable risk factors for gas exchange?
- factors affecting the heart’s ability to circulate blood (hypertension, atherosclerosis)
- Obesity
3, T2 DM - Smoking
- Stress and anxiety
If a pt opts to continue smoking or using tobacco what should the nurse do?
Respect the pt’s right to choose
What anatomical differences do children have in their thoracic cavity?
- shorter, narrower airway
- tracheal division hgiher, at a different angle
- lung tissue not fully developed at birth
- children under the age of 6 breath primarily with a diaphragm
How can secondhand smoke affect children?
- causes lungs to develop more slowly
- increase risk fo respiratory infections
- can trigger asthma
- can increase the incidence of wheezing and coughing
What health promotion enouragements should you give to parents that smoke?
encourage the parents to quit smoking, or if they decide to continue smoking to smoke outside and away from their kids
