1.2.3 Chest X-Ray Basics Flashcards
What is the standard distance of a PA CXR?
6 feet
More dense objects will show up how on an CXR?
More dense will be whiter and less dense will be darker
What is the normal heart size on a CXR?
Less than 1/2 the width of the chest
How would you describe the size of the heart in this patient?
Normal sized
How would you describe the size of the heart in this patient?
Heart is enlarged - cardiomegaly
How would you describe the size of the heart in this patient? What is important to note about this image?
This patient has cardiomegaly, but it is important to note that this is an AP image. This could cause the heart to appear larger than what it actually is.
Where would the fissures appear on a CXR?
Where would the divides occur on this lateral CXR?
What lobe is this highlighting?
Right upper lobe
What lobe is this highlighting?
Right middle lobe
What lobe is this highlighting?
Right lower lobe
What lobe is this highlighting?
Left upper lobe
What is this highlighting?
Lingula
What lobe is this highlighting?
left lower lobe
How will alveolar infiltrates look on a CXR compared to interstitial infiltrates?
Alveolar will look cloudy and interstitial will look like lines
On this CXR, the circled part appears to be affecting what?
The alveoli - note cloudy appearance
On this CXR, the infiltrates are affecting the?
Interstitium
What is the silhouette sign?
Structures that anatomically contact each other will obscure that border.
Why would you be able to say this infiltrate is in the left lower lobe?
It obscures the border of the diaphragm
Where is this infiltrate located?
Right upper border - affecting alveoli
What is being affected in this image?
Right middle lobe
This is a right middle lobe pneumonia
In regards to heart failure, what are the CXR findings and their respective PCWP?
What is occurring in this image?
This is normal
What would the PCWP be in this patient?
This person has PV congestion, their PCWP is most likely 12-18
What is the PCWP on this patient?
This patient has congestion and interstitial edema. Their PCWP is most likely 18-25
What is this patients PCWP?
This patient has alveolar edema caused by heart failure. Their PCWP would be greater than 25
Where are all the parts of the heart located?
What is wrong with this image?
Malpositioned PICC line into R subclavian vein
Where should a PICC line go?
Right at the SVC
What is wrong with this PICC line?
It is positioned too low in the RA, and can put the patient at risk for developing irregular heart beats
What is wrong with this image?
Malpositioned PICC line in the left jugular
What is wrong in this image?
This is a malpositioned ETT tube in the right bronchus
