Cardiopulmonary: Study Set 1 Flashcards
What are the general types of airway clearance techniques
Breathing strategies, manual and mechanical techniques, and postural drainage.
What are the indications for airway clearance
- Retained secretions in central airways
- Prophylaxis against post op complications
- Obtaining sputum for dx
- Difficulty clearing secretions
- Atelectasis caused by mucous plugging
What is atelectasis
collapse or partial collapse of the lung
What are the three phases of the ACB (active cycle of breathing)
Breathing control, thoracic expansion exercises, and forced expiratory technique.
What is an ABI and what is it used for?
An ABI compares systolic BP at the ankle and arm to check for peripheral artery disease
How is ABI taken and calculated?
An ABI measurement is done by taking the systolic BP of the brachial arteries bilaterally with a sphygmomanometer and tibialis posterior arteries bilaterally with a doppler ultrasound device
It is then calculated by dividing the highest ankle BP by the highest brachial BP
What ABI measurement is normal with no blockage
1.0-1.40
What is the ABI measurement of rigid arteries that require an additional ultrasound test to check for PAD
Greater than 1.40
What is the ABI measurement of mild blockage which could be the beginning of PAD
0.8 - 0.99
What is the ABI measurement of moderate blockage which could be associated with intermittent claudication during exercise
0.4 -0.79
What is the ABI measurement of severe blockage suggesting severe PAD and could cause claudication pain at rest
Less than 0.4
What is intermittent claudication
Pain felt in the calf with exercise and is relieved with rest
What is a contraindication of measuring ABI
deep vein thrombosis
When measuring arterial blood gas (ABG), what does pH stand for and what does its measurement indicate?
pH stands for potential hydrogen and it evaluates acid-base status. The balance of pH is dependent on PaCO2.
When measuring arterial blood gas (ABG), what does PaCO2 stand for and what does its measurement indicate?
PaCO2 stands for the partial pressure of Carbon Dioxide in arterial blood and it provides information regarding how well the lungs are able to remove carbon dioxide. Changes of PaCO2 directly affect the pH.
When measuring arterial blood gas (ABG), what does PaO2 stand for and what does its measurement indicate?
PaO2 is the partial pressure of oxygen in arterial blood and it provides information in combination with SaO2 (hemoglobin) about how well the lungs are functioning to oxygenate the blood.
When measuring arterial blood gas (ABG), what does HCO3- stand for and what does its measurement indicate?
HCO3- is bicarbonate and it plays a role in the chemical buffering system that keeps the blood from acidic or basic and is often part of an ABG test
When measuring arterial blood gas (ABG), what does SaO2 stand for and what does its measurement indicate?
SaO2 is the partial pressure of hemoglobin and it provides information in combination with PaO2 about how well the lungs are functioning to oxygenate the blood
In regards of ABG, what is the normal range of pH
7.35-7.45
In regards of ABG, what is the normal range of PaCO2
35-45 mm Hg
In regards of ABG, what is the normal range of PaO2
80-100 mm Hg
In regards of ABG, what is the normal range of HCO3-
22-25 mEq/L
In regards of ABG, what is the normal range of SaO2
95-98%
What is the correct order that ABG is written or spoken
pH/PaCO2/PaO2/HCO3-
