Q

What is the PASTE tool?

A

P: progression. Did the condition start suddenly or over time?
A: associated chest pain. Dyspnea can be a significant symptom of a cardiac problem.
S: Sputum. Has the patient been coughing up sputum? Mucus like sputum could indicate a respiratory infection.
T: talking tiredness. This could indicate how much distress the patient is in. Ask the patient to repeat a sentence and see how many words he can speak without needing to take a breath.
E: exercise tolerance. Ask the patient what he could do before the problem started like walk across the room. If he cannot do it now, it is another indicator that the person is in distress. Exercise tolerance will decrease as the breathing problem and hypoxia increase.

43
Q

What is Croup?

A

Inflammation and swelling of the pharynx, larynx, and trachea.

This disease is often secondary to an acute viral infection of the upper respratory tract and is typically seen in children between the ages of 6 months and 3 years. It is easily passed between children. Peak seasonal outbreaks if this disease occur in late fall and during winter. The disease starts with a cold, cough and a low grade fever that develops over 2 days. The Hallmark signs of croup are Strider and a seal-bark cough, which signal a narrowing of the air passage of the trachea that may progress into a significant obstruction. Crop is rarely seen in adults because their breathing passages are larger in can accommodate the inflammation and mucus production without producing symptoms.
Croup often responds well to humidified Oxygen. Note that bronchodilators are not indicated for Croup and can worsen a patient’s Symptoms.

44
Q

What is Epiglottitis?

A

Life threatening inflammatory disease of the epiglottis, the small flap of tissue at the back of the throat that protects the larynx and trachea during swallowing. Bacterial infection is the most common cause. This condition usually develops in otherwise healthy children, and symptoms are sudden and onset. Children with this infection look ill, report a very sore throat, and have a high fever. They will often be found in the tripod position and drooling. Strider is a late sign in the development of airway obstruction. Treat children with suspected epiglottis gently and try not to do anything that will cause them to cry. Keep them in a position of comfort, and give them high flow Oxygen. Do NOT put anything in their mouth come as this could trigger a complete airway obstruction. You should be concerned if your adult patient presents with Strider or any other sign of airway obstruction without an obvious mechanical cause. Focus your management on maintaining a patient’s (adequate) airway, And provide prompt transport to the emergency department.

45
Q

What is Respiratory Syncytial Virus (RSV)?

A

It is a common cause of illness in young children. It causes infection in the lungs and breathing passages, and can lead to other serious illnesses such as bronchiolitis and pneumonia, as well as serious heart and lung problems in premature infants and in children who have depressed immune systems. RSV is highly contagious and it can spread through droplets when the patient coughs or sneezes. The virus can also survive on surfaces come including hands and clothing. When you assess a child with suspected RSV, look for signs of dehydration. Infants with RSV often refuse liquids. Treat airway and breathing problems as appropriate. Humidified oxygen is helpful if available.

46
Q

What is Bronchiolitis?

A

It is a respiratory illness that occurs due to Respiratory Syncytial Virus (RSV) infection and results in severe inflammation of the bronchioles. Bronchioles, the tiny airways that lead from the larger airways (bronchi) to the alveoli in the lungs come become inflamed, swell, and fill with mucus. It occurs most frequently in newborns and toddlers, especially boys, whose airways can easily become blocked. Infections are common during the Winter and Spring. Young children who require hospitalization for bronchiolitis are in an increased risk for developing childhood asthma. The treatment for a child suffering bronchiolitis is mainly supportive. You should provide appropriate oxygen therapy and allow the patient to remain in a position of comfort. Reassess frequently for signs of worsening respiratory distress. Be prepared to provide airway management and positive pressure ventilation should the patient developed respiratory failure.

47
Q

What is Pneumonia?

A

Pneumonia is a general term that refers to an infection of the lungs. The infection collects in the surrounding normal lung tissues, in pairing the lungs ability to exchange oxygen and carbon dioxide. Pneumonia is often a secondary infection common meaning it begins after an upper respiratory tract infection such as a cold or sore throat. It can be caused by virus or bacterium, Or by chemical injury after an accidental ingestion or a direct lung injury from a subverts submersion incident.
Bacterial pneumonia results in severe symptoms more quickly including high fevers, would put the child at risk for febrile seizures. If our own among you have presents more gradually and his less severe. Regardless of the cause, treatment includes airway support in providing supplemental oxygen. Use oxygen with appropriate adjuncts, and provide supportive measures if needed period of valuate patient treatment through reassessment and prepare for possible deterioration in the patient’s condition.

48
Q

What is Pertussis?

A

Pertussis (Whooping Cough) is a airborne bacterial infection that primarily affects children younger than 6 years. Highly contagious and is passed through droplet infection. Patients will be feverish and exhibit a Whoop sounds on inspiration after a coughing attack. Symptoms similar to colds, but can last for more than a minute during which the child may turn red or purple.
In infants under 6 months Pertussis can be life threatening. Watch for signs of dehydration because children may vomit or not want to eat or drink. Give oxygen by the most appropriate means. Adults Pertussis does not cause to go whipping in when is that it doesn’t infants and toddlers. However, it can cause a severe upper respiratory infection, which can lead to pneumonia in geriatric patients or people with compromised immune systems

49
Q

What is Influenza Type A?

A

It is an animal respiratory disease that has mutated to infect humans. In 2009, the H1N1 strain of influenza type a became pandemic and outbreak that occurred on a global scale. Like seasonal flu, it may make chronic medical conditions worse. All strains of influenza type a are transmitted by direct contact with nasal secretions and aerosolized droplets from coughing and sneezing by infected people. Influenza type a virus can cause fever, cough, sore throat, muscle aches, headache, and fatigue and may lead to pneumonia or dehydration.

50
Q

What is Tuberculosis?

A

Tuberculosis TB is a bacterial infection caused by Mycobacterium tuberculosis. TB spreads by coughand is dangerous because many strains are resilient to antibiotics. TB most commonly affects the lungs but can also be found in almost any organ in the body, particularly the kidneys, spine, and lining of the brain and spinal cord (meninges). In some cases, TB can remain dormant (inactive) for years without causing symptoms or being infectious to other people. However when the person is in a state of weakened immunity, TB can become active again. The patient may not even be aware that he or she has the disease. Patients with active TB involving the lungs will report fever, coughing, fatigue, night sweats, and weight loss. If lung infection becomes severe, the patient will experience shortness of breath, coughing, productive sputum, bloody sputum, and chest pain.

51
Q

What is Hyperventilation syndrome(panic attack)?

A

Anxiety ,dizziness ,numbness, tingling of the hands and feet, spasms of the hands and feet. Patients often feel that they cannot catch their breath despite the rapid breathing. The syndrome occurs with the absence of other physical problems. It commonly occurs when the patient is experiencing psychological stress.

52
Q

What happens to the body with anaphylaxis?

A

Airway swells, blood vessel Dilation all over the body which may significantly lower blood pressure, widespread hives, itching, signs of shock, and symptoms similar to asthma. The airway may swell so much that the breathing problems can progressed to total airway obstruction in a matter of minutes. Most reactions occur within 30 minutes of exposure to the allergen.

53
Q

What is TIA(transient Ischemic attack)?

A

A disorder of the brain in which brain cells temporarily stops functioning because of insufficient oxygen, causing stroke-like symptoms that resolve completely within 24hours of onset.

54
Q

What is COPD?

A

Chronic obstructive pulmonary disease is a slow process of dilation is a disruption of the airways and alveoli caused by chronic bronchial obstruction. COPD is an umbrella term used to describe a few long diseases including emphysema and chronic bronchitis, an ongoing irritation of the trachea and bronchus. Most often it results from cigarette smoking. The most common form of COPD is emphysema.

55
Q

What is Emphysema?

A

The most common form of COPD. It is a loss of the elastic material in the lungs that occurs when the alveolar air spaces are chronically stretched due to inflamed airways and obstruction of air flow out of the lungs. Patients may present with adventures breath sounds such as crackles, rhonchi, and wheezes, or may have severely diminished breath sounds due to poor air movement.

56
Q

Whats the difference between Congestive Heart Failure and COPD?
Sounds?

A

CHF will most often sound Wet (Rhonchi, Crackles)
Happen quicker onset fluid overload
COPD will often have Dry sounds (Wheezes)
Happen slower onset of symptoms

57
Q

What is Asthma?

A

In acute spasm of the Bronchioles associated with excessive mucus production and with swelling of the mucous lining of the respiratory passages. 25 million Americans have asthma with highest prevalence rate seen in children aged 5 to 17.
