[Exam 3] Chapter 23 - -Management of Patients with Chest and Lower Respiratory Tract Disorders Flashcards
(209 cards)
Pulmonary Edema: What is this?
The abnormal accumulation of fluid in the lung tissue and alveolar space or sometimes both.
Pulmonary Edema: How is gas exchange here?
Difficult , will be SOB.
Pulmonary Edema: Fluid build up makes it difficult for O2 to do what?
Crossover from alveoli to capillary, gas exchange is impaired
Pulmonary Edema: Cardiogenic is often related to what?
HF, with fluid backing up into the lungs
Pulmonary Edema Non-Cardiogenic: What causes this?
There has been damage to the capillary lining.
Pulmonary Edema Non-Cardiogenic: What can damage to capillary lining be from?
Can be direct injury or indirect injury.
Pulmonary Edema Non-Cardiogenic: Direct injury includes what?
Chest trauma , smoke inhalaiton, pulmonary infection, aspiration, anyhting thats directly injured to capillary lining around alveoli
Pulmonary Edema Non-Cardiogenic: What are some examples of indirect causes?
Sepsis, burns, pancreatitis, something that sets off inflammatory process.
Pulmonary Edema Non-Cardiogenic: What happens to the capillary when injury occurs?
It becomes more permeable, meaning proteins and fluids are going to leak into the intersitial space and push on alveoli.
Pulmonary Edema Non-Cardiogenic: What problems occur when fluid accumulates?
Causes repsiratory difficulties, we arent able to get adequate gas exchange, and see them require a lot of oxygen
Pulmonary Edema Non-Cardiogenic: How is this treated?
You need to manage whatever disease process is causing this issue. If sepsis, treat sepsis. If chest trauma, treat that first.
Pulmonary Edema Non-Cardiogenic: Treatment different between this and Cardiogenic?
They are the same. You are wanting to get fluid out of the lungs except Hypoxia may exist even though we are giving them O2.
Pulmonary Edema Non-Cardiogenic: What does PEEP help with?
Helps open up the collapsed alveoli to help with gas exchange. Sometimes high PEEP doesn’t help them oxygenate. See decreased Sat levels.
Pulmonary Edema Non-Cardiogenic: What usually is activated here to cause this?
Inflammatory process is activated and capillary linings become permeable. Also seen in those with low albumin.
Acute Respiratory Failure: When does this happen?
When the patients cannot ventilate . Aren’t able to do gas exchange and cannot get enough oxygenation.
Acute Respiratory Failure: ABG values for acute?
pH < 7.35
CO2 > 50
PaO2 < 50
Resembles respiratory acidosis
Acute Respiratory Failure: Why does respiratory acidosis occur?
Because ventilaiton is impaired so bad that gas exchange is impaired.
Acute Respiratory Failure: what signs of respiratory acidosis may they show?
May be restless, may be fatigued, may have headache , confused, lethargy.
Can’t get enough oxygenation.
Acute Respiratory Failure: Why may symptoms get worse?
May happen as their respiratory failure gets worse
Acute Respiratory Failure Tx: How can we treat this?
Fix the underlying condition.
If caused by COPD, manage COPD.
May require intubation or ventilation.
Patho of ARDS: What is this?
Severe inflammatory process where there’s alveolar damage that leads to pulmonary edema.
Patho of ARDS: How are their oxygen levels?
Are hypoxic and are unresponsive to increased oxygen levels and PEEP
Patho of ARDS: Mortality rate for those that go into ARDS?
26-58 percent
Patho of ARDS - Causes: THis includes what?
Same causes of non-cardiogenic pulmonary edema.
Pneumonia, Shock, Sepsis, Drug Overdose, Aspiration. Trauma. Acute Injury.
