Flashcards in Chapter 13 - Respiratory Emergencies Deck (26):
What is Dyspnea?
Difficult or labored breathing accompanied by feeling short of breath.
What is diffusion?
A passive process where a substance move from an area of high concentration to one of lower concentration.
In terms of percentage, what is the chemical make-up of air?
1% other gasses
What effect does carbon dioxide have on the blood?
What is the primary muscle of respiration?
What are he main accessory muscles of respiration?
Pectoralis major and minor
In what structure does the oxygen/CO2 exchange occur?
What is the pleural space?
The "potential" space between the plera and the chest wall.
What is the pleura?
The thin membrane covering the outside of the lungs and inside of the chest wall.
Define airway patency.
A condition in which an airway is open and unobstructed.
What does COPD stand for?
Chronic Obstructive Pulmonary Disease
S/S of COPD?
Patient can not exhale adequate air
Increased mucus production
Persistent Productive Cough
S/S of Asthma?
Sudden, recurrent bronchiolar constriction
Increased mucous production
What does Hyperventilation cause to occur in the blood?
Low carbon dioxide levels.
What is DVT?
Deep venous thrombosis which are clots that form in the legs or pelvis and travel through the heart and into the pulmonary circulation.
What is a pulmonary embolism?
When an embolus travels to the pulmonary artery or branch completely or partially blocking it.
What is anoxia?
Lack of an oxygen supply
WHat is a pneumothorax?
An abnormal collection of air within the pleural space.
What is the most common cause of upper airway obstruction?
What is wheezing?
a high-pitched respiratory sound caused by a narrowing of the tubular airways.
What is bradypnea?
a decreased respiration rate of less than 10rpm in adults.
What is crepitus?
"crackling" feel of the skin indicating air under the skin.
Describe how to assess lung sounds.
1. upper lobes - anterior: 1.5" below the mid-clavicle - Left than Right
2. Lower lobes - anterior: at or below the nipple line and over the anterior midaxillary line - Left than Right
3. Upper lobes - posterior: between the top of the scapula and spine 2" below the neck - Right than Left
4. Lower lobes - posterior: below the bottom of the scapula - Right than Left
What is the hallmark of respiratory-related emergencies?
What respiratory rate(s) indicate impending respiratory failure?
less than 6-8 or greater than 30 in an adult.
