Exam 2 WTF I Do Not Know About RLD Flashcards
what happens to FEV1 FVC and FEV1/FVC in restricted Lund disease (RLD)
FEV1 reduced
FVC reduced
ratio: can RTS or increase
what happens to TLC in RLL
decreases
DLCO in RLL
reduced
intrinsic vs extrinsic RLL
intrinsic: decreased airway compliance, like the thickening or scarring of the inner tubes
extrinsic: reduced chest wall compliance, like obesity, deformities, scoliosis, trauma, burns
do occupational causes like asbestos, silicosis, coal minors have intrinsic or extrinsic RLD
intrinsic
what are the two idiopathic intrinsic RLDs
pulmonary fibrosis and sarcoidosis
do you have a dry or wet cough with intrinsic RLD
dry
what does a honeycomb on a CT mean
that there is probably fibrosis in the lungs
what does a 6MWT of less than 212 mean for prognosis
not great
what do you have if you have RLD with no known cause, destruction of alveoli and loss of capillaries, and less compliance.
Idiopathic pulmonary fibrosis
what is a multi-system autoimmune disease that can cause interstitial fibrosis
Sarcoidosis
in what disease does it look like your upper lobes have nodules and egg shaped calcifications of the hilarity nodes
silicosis
what affects alveolar septa
hypersensitive pneumonitis
what are some things that came extrinsic RLD
SCI, burns, smoke, inhalation, facial burn and fires
how do post polio patients breath
the upper thorax will rise, and the abdominals with suck in
what do you have when BMI is over 30 and you have PaCO2 of less than 45 mmHg, and you have fat deposits over the chest wall that make it very hard to excursion, and therefore more work to breathe
obesity-hypoventilation syndrome (Pickwickian)
what are the three big signs in obesity-hypoventilation or Pickwickian disease
BMI over 30
PaCO2 less than 45
sleep related apneas.
how does obesity change TLC, VC, FEV1, and FEV1/FVC
the TLC, VC and FEV1 are reduced,
the FEV1/FVC is usually spared
what happens when you have pharyngeal muscles that do not maintain potency and you have a fall is SaO2 levels
obstructive sleep apnea.
what do you have when you have narrowed airways with fatty deposits in the neck
you have obesity related asthma
how do your Diagnose Pulmonary HTN
pressure over 25 mmHg at rest, and over 30 mmHg during exercise.
what are the five groups of PHTN and what are the 3 most common
pulmonary arterial HTN (PAH) PHTN due to L ventricular dysfunction PHTN de to lung disease PHTN due to chronic blood clots and PHTN due to other diseases
what might you have if you have dyspnea with exertion at rest, dull rostrosternal chest pain, narrowS2 splitting with loud P2 and right heart failure.
pulmonary HTN
what is it when you have a rare, idiopathic dyspnea, with chest pain and syncope
PAH
what might you have when you are tachycardia, tachypnea, scattered rales, post surgery and on bedrest, and overweight, and decreased breathe sounds
atelectasis
when is atelectasis a problem in terms of developing pneumonia
over 72 hours.
how can you prevent atelectasis
10 breaths per hour, early mobilization, chasing position and coughing
what are the 4 phases of bacterial pneumonia
- congestion
- red hospitalization (fibrin and RBCs fill alveolar spaces, and looks reddish then neutrophils
- grey hospitalization (no new RBCs, and most are degraded.)
- resolution (al debris is cleared by neutrophils.
what kind of pneumonia might you have with abrupt onset, fever, chills, nausea, apprehension, flaring and grunting, and pain
bacterial
what type of pneumonia might you have with gradual onset, coughing without much mucus, malaise, wheeling, rales, nasal flaring
viral
what is the difference between type I and type II acute respiratory failure
type 1: hypoxia without hypercapnia
type 2: hypoxia and hypercapnia
what ribs are fractured with a high energy fracture
ribs 1-3
what happens with a flail chest
this is when 3+ ribs breaks, or 1 ribs breaks in 2+ places, and you have the chest falling in with inspiration and falling out with expiration. there is unequal chest expansion
what is a sucking chest
a pneumothorax
in what way does the mediastinum shift when you have a pneumothorax
towards the contralateral side
if you are spitting up blood, what are you likely to have
a PE
