Airway, Respiration, And Ventilation Flashcards
What is one key way to tell if manual ventilations are ineffective?
No chest rise
Explanation:
Chest rise indicates that the airway is open and you are delivering an adequate volume of air into the lungs.
The tiny air sacs at the end of the bronchioles are called ____.
Alveoli
What is a pneumothorax?
a buildup of air in the space between the chest wall and the lung
Early signs of hypoxia include ____.
increased heart and respiratory rate, anxiety, and restlessness
Explanation:
Hypoxia occurs when the tissues do not get enough oxygen, which can lead to symptoms of respiratory distress.
When is a jaw thrust maneuver used?
when a patient is unconscious and/or has a possible neck or spinal injury
Explanation:
A jaw thrust maneuver involves pushing the mandible upward and opening the airway without moving the patient’s neck.
Signs of labored breathing in a child can include ____.
retractions, nasal flaring, and grunting
Explanation:
Labored breathing indicates a person is working hard to get air in and out and they may use accessory muscles (which causes retractions), grunting, and nasal flaring.
Asthma often causes what type of breath sounds?
wheezing
Explanation:
Asthma may cause constriction of the airways, which causes a whistling sound referred to as “wheezing.”
What type of adjunct airway device should be used on a patient with an intact gag reflex?
nasopharyngeal airway
Explanation:
An oral airway may cause gagging in someone with an intact gag reflex. A nasal airway should be used if the gag reflex is intact.
What percentage of oxygen can be delivered with a Venturi mask?
24 to 40 percent
Explanation:
Special attachments corresponding to a certain liter flow allow a specific percentage of oxygen to be delivered.
What is a metered dose inhaler?
a small device used to deliver a set amount of aerosolized medication
Explanation:
A metered dose inhaler is often used to deliver medication to treat COPD and asthma.
What is a normal capillary refill time?
less than two seconds
Explanation:
more than two seconds is associated with decreased perfusion
Stridor can be a sign of ____.
upper airway obstruction
Explanation:
Stridor, which is a high-pitched wheezing or crowing sound heard in the upper airway, is often caused by a disruption of airflow.
What is end tidal CO2?
carbon dioxide exhaled from the lungs with each breath
Explanation:
Oxygen is inhaled into the lungs and carbon dioxide is exhaled.
What is gastric distention?
an accumulation of air in the stomach
Explanation:
Air can accumulate in the stomach if manual ventilations are too fast or forceful.
What is COPD
Chronic obstructive pulmonary disease (COPD) is a common lung disease causing restricted airflow and breathing problems. It is sometimes called emphysema or chronic bronchitis.
In people who have chronically high levels of carbon dioxide, the body gets used to the high levels and instead begins to base the drive to breathe on low oxygen levels. This is referred to as
hypoxic drive
What is Dyspnea
Dyspnea is shortness of breath or difficulty breathing that can occur for a variety of reasons. Respiratory illnesses, such as asthma and COPD, can lead to dyspnea. Additional causes of dyspnea include pulmonary edema, airway obstruction, and anxiety. Symptoms include shallow, rapid breathing and anxiety.
Pulmonary edema is
excess fluid in the lungs. It can occur suddenly due to congestive heart failure. Symptoms include shortness of breath, pink, frothy sputum, and a cough. The patient may also have crackles. Oxygen and the medication Lasix® (furosemide) are typical treatments.
COPD, or chronic obstructive pulmonary disease, is caused by damage to the _____ and is often due to smoking.
alveoli
Asthma is a chronic condition that can cause
increased mucus production, inflammation of the airways, and airway constriction. Symptoms may include wheezing, cough, and dyspnea.
Hay fever is an
allergic reaction to an allergen. Symptoms may include sneezing, cough, and runny nose.
Anaphylaxis is a
severe allergic reaction to an allergen. The condition can be life-threatening, since it can lead to airway swelling and a drop in blood pressure. Symptoms can include trouble breathing, stridor, and hives. Treatment includes epinephrine and airway management.
What is Spontaneous Pneumothorax
A pneumothorax involves air in the pleural space. It can occur spontaneously due to a lung infection, trauma, or for unknown reasons. Symptoms include chest pain, dyspnea, and decreased breath sounds over the affected area. Treatment includes inserting a chest tube to remove the air.
pleural effusion involves an
accumulation of fluid outside the lungs in the pleural space. It can occur due to an infection, congestive heart failure, and cancer.
