| |
Sleep Apnea - CORRECT ANSWER✔✔-Tongue and the soft palate fall backward
| | | | | | | | | | |
(upper airway) |
Partial or complete obstruction of the pharynx
| | | | | | |
Obstructs from 10 - 90 secs | | | | |
Causes severe hypoxemia (decreased PaO2) and hypercapnia (increased PaCO2).
| | | | | | | |
STOP BANG- snore, tired, obstruction, pressure, BMI, age, neck, gender
| | | | | | | | |
sleep deprivation, ↑ risk for cardiovascular event
| | | | | |
MI
Dysrhythmias
CVA
HTN
↑ injury risk
| |
MVA
Workplace
Priority concerns with COPD - CORRECT ANSWER✔✔-Ineffective airway
| | | | | | | |

Assessment and Collab Management Sleep Apnea - CORRECT ANSWER✔✔-
| | | | | | | |
Assessment
Sleep Lab |
Treatment
Mild: Lifestyle
| |
Weight Loss |
↑ HOB

↓ Alcohol & CNS depressants
| | | |
Consistent sleeping habits | |
Oral appliance Mandibular Advancement Device
| | | |
Forces lower jaw forward
| | |
CPAP Continuous Positive Airway Pressure
| | | | |
Splints airway open
| |
Compliance is often poor- needs to be worn every night
| | | | | | | | |
, A patient is admitted to hospital with acute exacerbation of COPD related to
| | | | | | | | | | | | |
influenza. ABGs and CXR are ordered and Sa02 is 86%. BP 168/102, P 104, RR 28
| | | | | | | | | | | | | | |
What is your priority intervention?

| | | | |
COPD - CORRECT ANSWER✔✔-Progressive Respiratory Disorder
| | | | |
Progressive airflow obstruction | |
Ongoing dyspnea, ⬇ activity tolerance, increased mucous & coughing
| | | | | | | |
Past Definitions of COPD include:
| | | |
Chronic Bronchitis |
Emphysema
Prevalence
Estimated 64 million worldwide (WHO) | | | |
1.5 million probable COPD in Canada; with over 1.5 million likely undiagnosed
| | | | | | | | | | |
Most become symptomatic in mid adulthood (~ 40 y.o)
| | | | | | | |
In Canada- 80-90% caused by smoking
| | | | |
Common Clinical Manifestations | |
-Congested cough | |
