Airway Quiz Flashcards
(28 cards)
What do Snoring Respirations mean?
Studies suggest snoring respirations are vibrations caused by relaxing upper airways that partially close while you’re asleep. Snoring respirations are entwined with sleeping position, sleep stage, and whether we breathe through the nose or mouth.
What is capnography?
Capnography is the monitoring of the concentration or partial pressure of carbon dioxide in the respiratory gases. Its main development has been as a monitoring tool for use during anesthesia and intensive care.
What is cyanosis and what causes it?
Cyanosis, broadly speaking, is caused by disorders of deoxygenated hemoglobin and disorders of abnormal hemoglobin. Oxygen might not reach hemoglobin in an adequate or sufficient amount as a result of conditions affecting the respiratory system, cardiovascular system, and the central nervous system
When is a BVM used?
A BVM should be used when you need to deliver high concentrations of O2.
What are Crackles, Stridor, Rales, Rhonchi?
- Crackles – Fluid in the lungs
- Rhonchi – Disease (pneumonia)
- Stridor – Infection in upper airway
- Rales – Rales are abnormal lung sounds that are rattling sounds or like a Velcro fastener being opened.
What is shallow breathing?
Shallow breathing, or chest breathing is the drawing of minimal breath into the lungs, usually by drawing air into the chest area using the intercostal muscles rather than throughout the lungs via the diaphragm. Shallow breathing can result in or be symptomatic of rapid breathing and hypoventilation.
What is a patent airway?
Patent airway. An airway that is open and clear and will remain open and clear without interference to the passage of air into and out of the body. Stridor. A high pitched sound generated from partially obstructed air flow in the upper airway.
Best way to assess lungs?
Auscultation using a stethoscope.
What is inhalation?
Inhalation is the process or act of breathing in, taking air and sometimes other substances into your lungs.\
What is exhalation?
The act of breathing out air. During exhalation, the diaphragm relaxes and moves upward, causing compression of the lungs and an outward flow of air. Also called expiration.
What is ventilation?
Ventilation: The exchange of air between the lungs and the atmosphere so that oxygen can be exchanged for carbon dioxide in the alveoli (the tiny air sacs in the lungs).
How long without O2 for brain damage?
4-6 min possible
6-10 min very likely
What is an OPA?
An oropharyngeal airway (also known as an oral airway, OPA or Guedel pattern airway) is a medical device called an airway adjunct used to maintain or open a patient’s airway.
What is gastric distention?
When using a BVM or any other ventilation device, be alerted for gastric distention, inflation of the stomach with air.
What is cystic Fibrosis?
CF is a genetic disorder that affects the lungs and digestive system
What sounds are in asthma and when does it happen?
Wheezing during inspirations/expiration. Excessive mucus in the bronchioles.
What is croup?
Infection of the upper airway. Seal barking sounds
Symptoms of hyperventilating?
Shortness of breath, or feeling that you can’t get enough air
A faster than normal heartbeat
Feeling faint, dizzy, or lightheaded
Pain or tightness in your chest
Frequent yawn or sighs
A numb, tingly feeling in your hands or feet
What is acute pulmonary edema?
Pulmonary edema occurs when fluid accumulates in the air sacs of the lungs – the alveoli – making it difficult to breathe. This interferes with gas exchange and can cause respiratory failure. Pulmonary edema can be acute (sudden onset) or chronic (occurring more slowly over time).
Adequate Breathing?
12-20 breaths/min
Regular inhalation/exhalation
Adequate depth(tidal volume)
Unlabored without adventitious breath sounds.
Drawback of manual ventilation?
Should not be used on patients with COPD or suspected cervical spine or chest injuries. Has difficulty maintaining airway.
When to replace O2 tank?
500 psi
Prone airway management?
The prone position improves oxygenation in intubated patients with acute respiratory distress syndrome.
Supine airway management?
supine is the most dangerous position for a patient with a compromised airway. The most detrimental position for a patient, from an airway perspective, is flat on their back. Supine is best described as the “COFFIN position,” or “Cannot Oxygenate Face Flat In Neutral position.
