  • Chest Auscultation: Presence/Absence and Equality of Normal/Abnormal and Adventitious Breath Sounds and Heart Sounds A
    Northwest Community EMS System Continuing Education: January 2012 RESPIRATORY ASSESSMENT Independent Study Materials Connie J. Mattera, M.S., R.N., EMT-P COGNITIVE OBJECTIVES Upon completion of the class, independent study materials and post-test question bank, each participant will independently do the following with a degree of accuracy that meets or exceeds the standards established for their scope of practice: 1. Integrate complex knowledge of pulmonary anatomy, physiology, & pathophysiology to sequence the steps of an organized physical exam using four maneuvers of assessment (inspection, palpation, percussion, and auscultation) and appropriate technique for patients of all ages. (National EMS Education Standards) 2. Integrate assessment findings in pts who present w/ respiratory distress to form an accurate field impression. This includes developing a list of differential diagnoses using higher order thinking and critical reasoning. (National EMS Education Standards) 3. Describe the signs and symptoms of compromised ventilations/inadequate gas exchange. 4. Recognize the three immediate life-threatening thoracic injuries that must be detected and resuscitated during the “B” portion of the primary assessment. 5. Explain the difference between pulse oximetry and capnography monitoring and the type of information that can be obtained from each of them. 6. Compare and contrast those patients who need supplemental oxygen and those that would be harmed by hyperoxia, giving an explanation of the risks associated with each. 7. Select the correct oxygen delivery device and liter flow to support ventilations and oxygenation in a patient with ventilatory distress, impaired gas exchange or ineffective breathing patterns including those patients who benefit from CPAP. 8. Explain the components to obtain when assessing a patient history using SAMPLE and OPQRST.

  • Prognosis in Bronchiectasis
    Arch Dis Child: first published as 10.1136/adc.6.31.1 on 1 February 1931. Downloaded from PROGNOSIS IN BRONCHIECTASIS BY LEONARD FINDLAY, M.D., D.Sc., M.R.C.P., Physician, East London Hospital for Children, Shadwell, and STANLEY GRAHAM, M.D., Physician, Royal Hospital for Sick Children, Glasgow. In 1927, we published in this journal' a communication embodying the results of our experience of bronchiectasis in childhood. We then expressed doubt regarding the correctness of the view held by some authors that the condition is curable. Nobecourt2, for example, in support of Hutinel3, has stated that recovery not infrequently does take place. This, he thinks, is brought about by the dilatation of the bronchi ceasing to increase, and, as the lung grows, the bronchi ultimately coming to have the normal proportions. Hutinel believed that the younger the age at which the bronchiectasis appeared the more likely was a cure to result. Thursfield and Paterson4 more recently have re-affirmed this favourable prognostic outlook. So far as we could see at the time of our first analysis the condition tended to get worse. From a study of the post-mortem material it was difficult, if not impossible, to understand how recovery could take place. Many of the lungs had the naked-eye appearance of a sponge or a hydatidiform mole. Naturally, of course, the post-mortem examples would be the most severe, though it is only fair to state that in several cases death had resulted from operative inter- ference and not in consequence of advancing pulmonary involvement.

  • Auscultation of the Lung As the Basic Method for Respiratory System Examination
    Auscultation of the lung as the basic method for respiratory system examination. The main and additional respiratory sounds Lung auscultation is an auscultation of the acoustic phenomena arising in a thorax in connection with normal or pathological work of the lungs. During auscultation it is necessary to estimate the main respiratory sounds, adventitious (additional) respiratory sounds and bronchophony. The main rules of lungs auscultation 1. It should be silent and warmly in the room where auscultation is carried out. 2. If it is possible the patient should be in vertical position (if the condition of the patient allows), and striped. 3. A stethoscope should be pressed to the chest wall firmly and uniformly. 4. In each point of auscultation 3 respiratory cycles should be listened. Remember: Sounds of low frequency are better conducted in using of a stethoscope without a membrane, especially with wide funnel, and at weak press of a stethoscope to the skin. Sounds of high frequency are auscultated better by means of a phonendoscope with a membrane, at strong press to the skin, or by means of Technique of lung a stethoscope with narrow auscultation funnel. by means of phonendoscope During auscultation the phonendoscope is placed in strictly symmetrical sites of the right and left sides of the chest practically in the same zones as during carrying out of comparative percussion. It is necessary to remember, that during carrying out of auscultation of the lungs in lateral parts of thorax hands of the patient must be raised and clamped at the back of the head. During auscultation behind the patient should be asked to cross his arms on the chest and to lower his head slightly.

  • Bronchophony. Thisis More Intense Than Normal Vocal
    AN INVESTIGATION INTO SOME OF THE PRIN- CIPLES OF AUSCULTATION. By ALBERT A. GRAY, M.D. Glasgow. (Continued from page 232.) PART II.-B. Changes in Quality of Sound conducted through the Lung. HITHERTo differences in intensity of the auscultatory signs have been considered. It remains to investigate the differences in quality which occur when sound is transmitted through the lungs to the ear. It is evident that in this part of the investigations the tuning-fork can help us but little: being a pure note, either entirely without audible partial tones, or very nearly so, there can be no change in the quality of the sound. For the most part we must depend upon the voice and the respiratory murmur to represent compound tones and sounds. Of these two the voice is, for the present purpose of investigation, the more valuable, because we know exactly where it is pro- duced and its acoustic characters; but there is some doubt as to the point of generation of the respiratory murmur. The physician recognizes four types of the thoracic voice,- the Normal Vocal Resonance; Bronchophony; £Egophony; and Pectoriloquy. The characteristics usually associated with each are: (1) Normal Vocal Resonance. An indefinite humming or buzzing noise; the spoken words are not distinguish- able. (2) Bronchophony. This is more intense than normal vocal resonance; the words are distinguishable; it is usually associated with increased vocal fremitus. (3) }Egophony. The voice is not quite so intense as in bronchophony, and is not associated with increase of INVESTIGATION INTO SOME PRINCIPLES OF AUSCULTATION. 355 the vocal fremitus.
