EC Chp 17 Respiratory Emergencies Flashcards

1
Q

Inspiration or Inhalation

A

An active process which the intercostal muscles and the diaphragm contract, expanding the size fo the chest cavity and causing air to flow into the lungs

Q

Expiration or Exhalation

A

A passive processs in which the rib muscles and diaphragm relax causing the chest cavity to decrease in size and forcing the air from the lungs

Q

Wheezes indicate?

A

Very common in asthma and COPD - emphysema and chronic bronchitis

They are high pitches sounds created by air moving through narrowed passages and most commonly heard through expiration

Q

Rhonchi sounds like what?

A

Lower pitched sounds that resemble snoring or rattling. Which are caused by secreations in larger airways and may be seen in pneumonia or bronchitis or when materials are aspirated in the lungs
(Loser than crackles)

Q

Continuous Positive Airway Pressure (CPAP) is?

A

A form of non-invasive positive pressure ventilation (NPPV) consisting of a mask and a means of blowing oxygen into the mast to prevent the airway collapse or to helps alleviate difficulty breathing

Q

Contraindications for CPAP are

A

Mental status or lack of a normal respiratory rate, inability to sit up, hypotension, and inability to maintain a good mask seal.

Nausea, vomiting, penetrating chest trauma, shock, upper GI bleeding, facial trauma

Q

Side effects of CPAP

A

Cardiac input decreases resulting in drop in BP need to have Systolic BP of 90 mmHg
Hypotension
Pneumothorax (lung collapse
Increased aspiration

Can cause a weak section of the lungs to rupture, especially in patients with COPD and asthma
And drying of the cornea of the eyes

17
Q

Chronic Bronchitis means

A

The bronchiole lining is inflamed and excess mucus is formed.
(Crackles are heard)

18
Q

emphysema is

A

When the walls of the alveoli breakdown, greatly reducing the surface area for respiratory exchange and lungs lose elasticity

Combined air laden with Co2 is trapped in the lungs reducing effectiveness of breathing efforts

19
Q

Asthma

A

A chronic disease that has episodic exacerbations or flares (affect the patient at irregular intervals).

While emphysema and chronicle Bronchitis continuously effect the patient

20
Q

What happens in an asthma attack?

A

The small bronchioles that lead to the air sacs of the lungs become narrowed because of the contractions of the muscles that make up the airway. Mucus is produced and small passages practically close down

The air flow is mainly restrained in one direction

21
Q

Pulmonary Edema

A

abnormal amount of fluid accumulated in the lungs. And effects patients with congestive heart failure

22
Q

Patients with CHF often have both left and right sided heart failure because…

A

The right side that receives blood from the body also backs up in the systematic circulation which can led to edema in lower parts of the body (legs)

23
Q

Signs of pulmonary edema

A

Recent weight gain in just a few days
Anxiety, place and sweaty skin, tachycardia, hypertension,
Respiration’s are rapid and labored and low oxygen saturation.

24
Q

Treatment for pulmonary edema

A

High concentrations of oxygen by mask unless the patients breathing is inadequate then you need to ventilate. And keep the patients legs on a depending position (hanging down)

25
Q

Pneumonia is?

A

An infection fo one or both lungs abused by bacteria, viruses, or fungi. It results from inhalation of certain microbes that grow in the lungs and cause inflammation. People with COPD and other respiratory diseases are more likely to get it.

26
Q

Signs and symptoms o Pneumonia

A

Coughing mucus (yellow, green, or bloody)
Fever, chest pain and severe chills.
Most but not all complain of shortness of breath with or without exertion.
Chest pain that is sharp and PLEURITIC(worsens on inhalation.
May hear crackles in just one region

27
Q

Pleuritic:

A

Sharp chest pain that worsens on inhalation.

28
Q

What is a Spontaneous Pneumothorax?

A

When a lung collapses without injury or another other obvious cause. And air leaks into the thorax.

This is usually a result of a rupture of a bleb (small section of the lung that is weak).

29
Q

Bleb

A

small section of the lung that is weak

30
Q

Symptoms and signs of spontaneous pneumothorax

A

A sharp, pleuritic chest pain and shortness of breath.
Tire easily, tachycardic, breath fast and cyanosis
Do NOT provide CPAP

31
Q

Pulmonary Embolism can be defined as?

A

When blood clot, air or fat gets stuck in the blood vessel or artery in the lungs. Most common is a blood clot and starts in the vein in the leg or pelvis

32
Q

A dangerous type of clot is

A

Deep Vein Thrombosis (DVT)

Occurs a lot in cancer patients and those sitting in one position for an extended period

33
Q

Other things that can block pulmonary arteries are

A

Significant amount of air

Marrow of a fractured bone

34
Q

Signs and symptoms of pulmonary embolus are

A

Extremely variable making it difficult to tested.

Administer oxygen and keep a high index of suspicion

35
Q

Epiglottitis

A

When an infection inflames the area around and above the epiglottis and can occlude or close off the airway.

Do not inspect the throat or agitate it anyway

36
Q

Epiglottitis was more a of childhood infection but now less common due to

A

Vaccination haemophilus influenzae type B.

37
Q

If Epiglottitis is not treated what percent can die?

A

10%.

38
Q

Cystic Fibrosis (CF) causes?

A

A genetic disease that causes a thick sticky mucus that accumulates int he Lungs and Digestive system. The mucus can cause life threatening infections.
No known prevention

39
Q

Symptoms of CF

A 
Coughing with large amounts of mucus
Fatigue
Frequent pneumonia 
Abdominal pain
Coughing blood
Nausea and weight loss.
40
Q

Viral Respiratory Infection (common cold)

A

The most common affliction a person may get.

The cough can be persistence and produce sputum that is yellow or green. It usually for one or two weeks.

41
Q

Bronchoconstriction and most people with get what?

A

Constriction or blockage of the bronchi that lead front eh trachea to the lungs. Most people receive an inhaler with meds of a fine powder

42
Q

Medication used in metered dose can also be administered via a?

A

SVN or small-volume nebulizer. Allows meds to be taken during multiple breaths over several minutes due to the continuous flow
Used in hospitals and ambulances and prescribed to patients
