RESPIRATORY Flashcards
Best objective measurement for asthma
Peak flow
Chronic, reversible, triggers, children can have apenic periods/decreased HR
Asthma
What is the problem with asthma? What phase is prolonged? When does wheezing occur?
Problem with air getting out due to vasoconstriction. Expiratory phase is prolonged. Wheezing initially on exhalation and then worsens to inhalation.
What is a big risk for patients with bronchiolitis?
Dehydration due to increased RR and poor feeding - give humidified oxygen
Intermediate step b/t O2 and intubation
CPAP/BiPAP
What kind of CXR infiltrate typically is seen with PNA? TB?
PNA = middle/LL
TB = upper lobe
When do antibiotics need to be given for strep PNA?
Within 4 hours
cramping hands/feet d/t hyperventilation
carpopedal spasms
What 6 things are risk factors for a pneumothorax?
-Marfans
-Ehlers Danlos
-Smoking
-Drugs
-Meds
-Prior PTX
When do we get a CXR for PTX patients with a chest tube?
Immediately after insertion and at 4 hours
What lung sounds do we hear in pts with a PTX?
absent or markedly decreased
How much blood in a patient with a hemothorax needs OR/open thoracotomy?
> 1000 mL
What kind of shock does a tension PTX cause?
Obstructive due to pressure on the mediastinum
How do we treat a tension pneumo?
Immediately with a 14g/3.25” or larger needle @ 2nd ICS MCL affected side, reassess, will need chest tube and OR
What symptom does a PE cause? What kind of shock can a large PE lead to?
Progressive and unexplained SOB
Obstructive shock
Diffuse inflammatory response in lungs; sudden, progressive, severe; diffuse b/l infiltrates; commonly assoc with pulm contusion
ARDS
What are the 7 Ps in RSI?
-Prepare
-Pre-oxygenate (also “do-nitrogenation” - 100% O2 x 3 minutes with NRB)
-Pre-treat (sedate, consider lido for ICP protection and atropine in peds to prevent bradycardia)
-Paralyze
-Placement (Sellick = crich pressure)
-Proof (observe, listen, ETCO2, CXR)
-Post-intubation
What kind of pressure do we typically have? What kind of pressure does a vent use?
We use negative pressure; vent uses positive
