Oxygen Needs : Info from Mosby's Canadian Textbook for the Support Worker - E-Book – Sheila A. Sorrentino, Leighann Remmert, Mary J. Wilk, Rosemary Newmaster Flashcards
A sensitivity to a substance that causes the body to react with signs or symptoms, such as a runny nose, wheezing, congestion, or difficulty breathing
allergy
The lack or absence of breathing
apnea
Slow breathing; respirations are fewer than 12 per minute.
bradypnea
Respirations gradually increasing in rate and depth and then becoming shallow and slow; breathing may stop ( apnea ) for 10 to 20 seconds. This type of respiration is common when death is near.
Cheyne-Stokes
An abnormal condition, evidenced by bluish colour in the skin, lips, mucous membranes, and nail beds caused by a lack of oxygenated blood in the visible tissues.
cyanosis
Difficult, laboured, or painful breathing
dyspnea
Normal breathing.
eupnea
Bloody sputum
hemoptysis
Respirations that are more rapid and shallower than normal. Sometimes, respirations may be more rapid and deeper than normal.
hyperventilation
Respirations that are slow, shallow, and sometimes irregular.
hypoventilation
A deficiency of oxygen in the cells.
hypoxia
Deep, rapid respiration characteristic of diabetic acidosis or other conditions causing acidosis.
Kussmaul respiration
The inability to breathe deeply and comfortably unless sitting or standing
orthopnea
Sitting up and leaning over a table to breathe.
orthopneic position
Rapid breathing; respirations are 24 or more per minute.
tachypnea
Hemoglobin is made up of
iron, and it picks up oxygen in the lungs and carries it to the cells.
How does aging affect breathing and the health of the lungs?
Respiratory muscles weaken and lung tissue becomes less elastic with advancing age, making coughing more difficult.
List factors that affect oxygen needs.
Respiratory system function, Cardiovascular system function, Red blood cell count, Nervous system function, aging, exercise, fever, pain, drugs, smoking, allergies, pollutant exposure, nutrition, alcohol, drug overdose
The following are signs and symptoms of what?
• Restlessness • Dizziness • Disorientation • Confusion • Behaviour and personality changes • Difficulty concentrating and difficulty following directions • Apprehension • Anxiety • Fatigue • Agitation • Increased pulse rate • Increased rate and depth of respirations • Sitting position, often leaning forward
hypoxia
What is the name for an abnormal condition, evidenced by bluish colour in the skin, lips, mucous membranes, and nail beds in light-skinned clients.
cyanosis
What is the name of the device used to measure oxygen concentration in arterial blood as well as for measuring pulse rate.
pulse oximeter
How many breaths per minute do normal adults take?
12 to 20
How can a PSW promote oxygenation in a client?
(1) proper positioning and frequent rest periods and (2) encouraging coughing and deep breathing.
The best time to collect sputum is :
a) on awakening
b) after meals
c) at bedtime
d) after suctioning
On awakening
