Cardio Pulm Review Flashcards
What is the primary action of Expectorant agents?
Increase respiratory secretions, which help to loosen mucus. Reducing the viscosity of secretions and increasing sputum volume improves the efficiency of the cough reflex and ciliary action in removing accumulated secretions.
What is the primary action of Mucolytic Agents?
Decrease the viscosity of mucus secretions by altering their composition and consistency, making them easy to expectorate.
When is Oxygen therapy indicated?
In patients with PaO2
What are the indications for tracheostomy?
airway obstruction at or above the level of the larynx and respiratory failure requiring prolonged mechanical ventilation
What are the ratings of the Angina Pain Scale?
1 - mild, barely noticeable
2 - moderate, bothersome
3 - moderately severe, very uncomfortable
4 - most severe or intense pain ever experienced
What are the values for the ABI?
> = 1.3 - indicates rigid arteries and need for an ultrasound test to check for PAD
1-1.3 - Normal; no blockage
.8-.99 - mild blockage, beginnings of PAD
.4-.79 - Moderate blockage, may be associated with intermittent claudication during exercise
How is the ABI calculated?
High of the two blood pressure measurements in ankles/ higher of the two systolic BP measurements in the arms
What is the S1 heart sound characterized by?
(lub) 1st heart sound closure of the mitral and tricuspid valves at the onset of ventricular systole
What is the S2 heart sound characterized by?
(dub) 2nd heart sound - closure of the aortic and pulmonic (semilunar) valves at the onset of ventricular diastole
What is the S3 heart sound characterized by?
vibrations of the distended ventricle walls due to passive flow of blood from the atria during the rapid filling phase of diastole
Normal in health young children, abnormal in adults associated with heart failure - “ventricular gallup”
What is the S4 heart sound characterized by?
Pathologic sound of vibration of the ventricular wall with ventricular filling and atrial contraction
May be associated with ht., stenosis, hypertensive heart disease or MI - “atrial gallup”
Describe the path of blood flow through the heart
O2 poor blood enters right atrium via SVC and IVC->tricuspid valve opens and blood enters the right ventricle-> pulmonary valve opens and blood enters pulmonary artery to go to the lungs -> O2 rich blood returns to heart from lungs via pulmonary veins to the left atrium -> mitral valve opens allowing blood to flow into the left ventricle -> aortic valve opens pushing blood into the aorta and then to the rest of the body
Describe normal tracheal and bronchial sounds
loud tubular sounds, normally heard over the trachea
Inspiratory phase shorter than expiratory phase
Describe normal vesicular breath sounds
high pitched, breezy sounds normal heard over the distal airways
Inspiratory phase longer than expiratory phase
Describe crackles (formerly rales)
Discontinuous, high pitched popping sound more often heard during inspiration
Often heard in the bases of the lungs with interstitial lung disease, atelectasis, pneumonia, bronchiectasis, and PE
Describe pleural friction rub
dry, crackling sound heard during both inspiration and expiration
Describe Ronchi
continuous low-pitched sounds described as having a snoring or gurgling quality that may be heard during inspiration and expiration
Describe stridor
Continuous high pitched wheeze heard with inspiration or expiration
Indicative of upper airway obstruction
Describe wheeze
Continuous musical or whistling sound compose of a variety of pitches
Arise from turbulent airflow and the vibrations of the walls of small airways
Describe bronchial breath sounds
abnormal breath sounds that are heard where vesicular sounds are normally present. (pneumonia may produce these sounds)
Describe Broncophony
Increased vocal resonance with greater clarity and loudness of spoken words (e.g. 99)
Describe Egophony
A form of bronco phony in which the long “E” changes to a long nasal sounding “A”
Describe whispered pectoriloquy
recognition of whispered words “1, 2, 3”
What are normal and abnormal fill times for capillary refill?
2 s - abnormal - capillary blood flow is compromised
What are the classifications for lymphedema?
Mild - 5cm difference between limbs
