A 
relatively new
-common uses are...

Q

crackles

A

Q

rhonchi

A

lower pitched sounds that resemble snoring or rattling.
caused by secretions in larger airways like pneumonia or bronchitis. (or when material is aspirated into lungs)

generally louder than crackles

Q

emphysema

A

walls of the alveoli break down, greatly reducing the surface area for respiratory exchange.

the lungs begin to loose elasticity.

Q

asthma

A

attacks can be brought on by

  • insect stings
  • air pollution
  • infection
  • exercise
19
Q

pulmonary edema

A

patients with congestive heart failure may experience difficulty breathing because of fluid that accumulates in the lungs, preventing them from breathing adequately

-abnormal accumulation of fluid in the lungs

20
Q

CHF (congestive heart failure)

A

patients with CHF often have a both sided heat failure.

-CHF patients might also have JVD, bulging of neck veins, and accumulation of fluid in the abdominal cavity

-can overload the system and leak into the lungs. causing dyspnea
-signs
anxiety
diaphoretic
tachycardia
high BP
fast and labored respirations
low O2 saturation

21
Q

CHF and pulmonary edema treatment

A

keep legs dangling to minimize the fluid pressures in the upper body.

high concentration O2 if the patient is breathing adequately

assisted ventilations if needed

CPAP is also effective to push fluid out from the lungs and back to into the capillaries. (where it belongs)

22
Q

pneumonia

A

infection in one or both lungs caused by bacteria, virus, or fungi.

23
Q

symptoms of pneumonia

A
  • coughing up mucus
  • fever
  • chest pain
  • severe chills

on auscultation, crackles may be heard

24
Q

treatment of pneumonia

A

EMT can administer O2 through CPAP

-anti biaotics can be given at the hospital

25
Q

Spontaneous pneumothorax

A

when a lung collapses without any injury or any other obvious cause.

usually caused by a rupture of a bleb (a weak point in the lungs)

  • lungs collapse and air leaks into the thorax
  • auscultation is not a good test for this condition, because some patients may sound like they have normal lung sounds.

-pain is sharp pleuritic chest pain, shortness of breath

26
Q

treatment of spontaneous pneumothorax

A

treat with O2 like any patient that is suffering from shortness of breath.

-some patients may need a catheter or larger plastic chest tube inserted between the ribs into the plural area. (this catheter would remove the trapped air)

27
Q

pulmonary embolism

A

blood clot that travels into the pulmonary system and can cause shock, or cardiac arrest

these clots are called (DVT)
deep vein thrombosis

28
Q

signs of pulmonary embolism

A
  • sudden onset of sharp pleuritic chest pain
  • shortness of breath
  • anxiety
  • cough (often with bloody sputum)
  • sweaty, pale, or cyanotic skin
  • tachycardia
  • tachypnea
29
Q

treatment of pulmonary embolism

A
  • administer O2 (keep suspicion of patients who have recently been immobile or history of DVT
  • can be avoided by staying active
30
Q

epiglottits

A

when the epiglottis closes up due to infection.

caused by swelling and inflammation.

used to be very common in kids, but has dropped due to vaccinations

vaccines against haemophilus influenza type B

31
Q

symptoms of epiglottits

A
  • sore throat
  • painfull and difficult swallowing
  • typically patients are found in tripod position
  • drooling
32
Q

treatment of epiglottits

A
  • doing as much as possible to keep the patient calm
  • administering O2 without alarming the patient
  • not inspecting throat
  • child cases have a 10 death rate
  • hospital should be notified of the possibility of having the condition
33
Q

cystic fibrosis

A
  • genetic disease that typically appears in childhood.
  • causes thick sticky mucus that accumulates i the lung and digestive system
  • can cause life threatening lung and digestive infections

-no known prevention of CF

34
Q

signs of cystic fibrosis

A
  • coughing w/large amounts of mucus
  • fatigue
  • frequent occurrences of pneumonia (fever, increased pneumonia symptoms)
  • abdominal pain
  • coughing up blood
  • nausea
  • weight loss
35
Q

viral respiratory infections

A
  • scratchy throat
  • sneezing
  • runny nose
  • fatigue
  • possibly fever/chills

treatment:
-O2
alcohol based hand sanitizer

36
Q

prescribed inhaler

A
  • contains drugs that dilate air passages
  • used with a spacer (aero chamber)
  • should be at least room temperature
  • patient must be alert enough to use inhaler
  • exhales deeply before usage
  • must hold breath as long as possible after application of medication.
37
Q

types of meds used in inhalers

A

-albuterol (ventolin, proventil, volmax)
-levabuterol (xopenex)
-combination inhaler albuterol and ipratropium (combivent)
these are all used in emergency cases to reverse an airway constriction

38
Q

small volume nebulizer (SVN)

A
  • nebulizes a medication with oxygen and air/liquid
  • patient breaths in vapors
  • home use with patients suffering from (asthma, COPD)
39
Q

side effects of nebulizer

A

some side effects may include

  • increased pule rate
  • tremors
  • nervousness
  • jittery feeling
  • patient must be breathing deeply enough for the medication to work. (getting to lungs)
40
Q

patients inability to lie down

A

usually caused by fluid build up in lungs. a symptom of heart failure (CHF)

41
Q

patient with difficulty breathing, fever and mucus build up

A

likely suffering from COPD

42
Q

patient who had prior history of heart attack and gained weight recently

A

likely suffering from heart failure (CHF)

43
Q

ronchi

A

lower pitched sounds that resemble snoring or rattling

  • common in pneumonia or bronchitis
  • when material is aspirated into the lungs
