ULTRASOUND IN BEDSIDE DIAGNOSIS
Ultrasound is a versatile diagnostic modality permitting real-time bedside visualization of dynamic anatomy synergizing naturally with the physi­cal exam. If ultrasound is being considered to conrm or exclude a disease process, then an initial bedside ultrasound could prove useful increasing efciency.
Technical Considerations: A basic understanding of the physics of ultraso-
nography is essential for proper use of this tool. Ultrasound imaging detects ultrasound waves reecting from the body’s tissues. The intensity of the reected wave is directly proportional to the tissue density. The exceptions are gas-lled structures which do not transmit the ultrasound wave and therefore block penetration to deeper structures, and, at the other extreme,

bone so dense that ultrasound cannot penetrate. The boundaries between tis­sues of different density are seen most clearly. This is an important consider­ation in deciding which probe to use and how to obtain the best image.

This adjusts the signal amplication, essentially how hard the machine
“listens” for returning echoes. As the gain is increased, all returning echoes are amplied producing a brighter image. The correct gain is that which bal­ances the desired signal against the background noise.

ring in a one-dimensional scan line is displayed on the vertical axis over time on the horizontal axis. It is used in conjunction with B-mode scanning. The M-mode cursor is placed over the moving object on the B-mode image, and the M-mode button is pressed. This is very helpful in measuring the respi­ratory variability of the inferior vena cava (to assess volume status) and in evaluating the chest for pneumothorax.
Probe selection. Ultrasound probes are described by the size and shape of their face (footprint). High-frequency probes provide better resolution at the expense of decreased penetration compared with low-frequency probes which provide better penetration with less resolution. Three basic probes are used for a goal-directed ultrasound.
Linear (frequency 5–13 MHz). High frequency and better for imaging super­cial structures and vessels.

maneuvering between ribs which is ideal for echocardiography.
Ultrasound orientation. Orientation is a key to understanding what is seen on the display screen. The two main aspects of orientation are: (1) how the indicator is oriented relative to the screen, and (2) how the probe and the indicator are oriented relative to the patient. Ultrasound orientation can be challenging because it involves understanding how a two-dimensional plane cuts through a three-dimensional object not just in the three standard planes (sagittal, transverse, or coronal), but at any orientation.
Smaller footprint which allows

Indicator–screen orientation. The “indicator” on the probe may differ be­tween manufacturers but is typically a bump or a groove. There are two rules for this orientation: (1) the left side of the screen corresponds to the side of the probe marked with the indicator, and (2) the top of the screen displays structures closer to the probe and the bottom of the screen those farthest away from the probe.
Indicator–patient orientation.
the probe is placed on the patient, and images are viewed on the screen. Most diagnostic ultrasounds are performed using the standard orientation where the indicator (screen left) is toward the patient’s right, patients head, or in the arc between these directions.
Anatomic planes. There are three standard anatomic planes scanned in diag­nostic ultrasonography.

the anterior surface of the patient with indicator directed toward the pa­tient’s right. In this orientation, anterior structures will be toward the top of the screen, and right-sided structures will be on the left side of the screen as viewed.
Sagittal plane. The sagittal plane is obtained by placing the probe on the anterior of the patient with the indicator toward the patient’s head. In this orientation, anterior structures will be toward the top of the screen, and the patient’s head (cephalad structures) is to the left of the screen and feet (caudal structures) to the right.
Coronal plane. The coronal plane is obtained by placing the probe on the right or left ank with the indicator to the patient’s head. If the probe is on the right ank, the top of the screen will be right and the bottom left. If the probe is on the left, the top of the screen will be left and the bottom right. In both the cases, the indicator should be directed to the patient’s head, and thus the cephalad structures will be on the left of the screen and caudal structures will be on right.
Scope of Ultrasound in Diagnostic Examination
Symptom- or sign-based ultrasound. This uses specic algorithms that delineate which organ system should be examined based on patient’s primary complaints, e.g., shortness of breath, chest pain, undifferentiated hypotension, or undifferentiated abdominal pain. Bedside ultrasound should be limited and goal-directed, which means that the purpose of the examination must be clearly specied and goal-directed to impact the clinical decision­making of the physician performing the exam. If there is suspicion of a particular disease, the study should be limited to a specic organ system that can be expeditiously evaluated. After formulating a diagnostic hypothesis and differential diagnosis based on the patient’s presenting symptoms and signs, a quick focused ultrasound may identify the correct diagnosis and has­ten treatment. These are some examples where ultrasound can be a useful adjunct to physical examination:

abdominal aortic aneurysm, acute cholecystitis, or hydronephrosis.
Chest pain and shortness of breath. The chest can be evaluated for pleural
effusion and the lung for interstitial pulmonary edema. The heart can be assessed for systolic function, pericardial effusion, and signs of right ventricular strain.
Hypotension. Bedside ultrasound can quickly evaluate for free uid and

The Diagnostic Examination: Chapters 4 to 15
This section, organized by body region, explains the diagnostic utility of the symptoms and signs commonly associated with each region, often with a brief summary of the relevant physiology.
Each chapter is organized in the following sequence:
A brief review of the Major Systems examined, including relevant physi­ology, and anatomic landmarks.
The Physical Exam of the region.
The Symptoms commonly associated with region.
The Signs commonly encountered during examination of this region.
The Diseases and Syndromes associated with symptoms and signs in the region.
The symptoms and signs are set in boldface type as paragraph heads. These are clues to the pathophysiology of each disease which is important for accurate diagnostic hypotheses. The key symptoms are commonly chief complaints. The clinician should be familiar with the diseases and syndromes summarized in the last subsection.
Symptoms, signs, and syndromes marked with the icon need for urgent evaluation to avoid delaying diagnosis of a life-threatening condition.
The signs are placed in approximate order as they are encountered dur­ing the head-to-foot physical exam.
When particular symptoms and signs are useful in differentiating between the various etiologies, they are discussed after the
Some ndings are both a symptom and a sign. For instance, severe jaun­dice can be both the patient’s symptom and a clinical sign. In these instances, the nding is discussed where it most commonly occurs: vomiting is most often a symptom, though it can be witnessed; tenderness, although noted by the patient, is a sign elicited by the examiner.
Diseases and syndromes associated with each symptom and sign are listed under

Vital Signs, Anthropometric
Data, and Pain
This chapter discusses the vital signs (temperature, pulse, respirations, and blood pressure [BP]), followed by measures of body size (height, weight, and body-mass-index [BMI]), and nishes with pain assessment.
VITAL SIGNS
Why are temperature, pulse, respirations, and BP called vital signs? These are the signs of life (L. vitalis, from vita: life); their presence conrms life and their absence conrms death. The more abnormal these parameters become, singly, but especially in combination, the greater the life is threatened. Since ancient times, practitioners have used skin temperature, pulse, and respira­tions as prognostic signs. More recently, the BP was found to have similar pre­dictive value. Entire texts were written on the interpretation of pulse, fever, and respiratory patterns. It is now apparent that these signs are insufcient for establishing a specic diagnosis. On the other hand, they are sensitive indicators of disordered physiology and are useful in forming pathophysi­ologic hypotheses and differential diagnoses. They are strongly correlated with severity of illness and outcome.
Body Temperature: Internal body temperature is tightly regulated to main-
tain vital organ function, particularly the brain. Temperature deviation of more than 4°C above or below normal can produce life-threatening cellular dysfunction. Internal temperature is regulated by the hypothalamus, which maintains a temperature set point. The autonomic nervous system maintains body temperature by regulating blood ow, conducting heat from the inter­nal organs to the skin, and innervating sweat glands. Increasing ow and dilating cutaneous capillaries radiate heat away by conductive loss whereas sweat increases evaporative heat loss. Behavioral adaptations are also impor­tant. In hot conditions, people become less active seeking shade or a cooler environment. Decreased body temperature is countered by shivering, which generates heat, and by behavioral adaptations such as putting on clothes and seeking a warmer environment. Sustained temperature deviation indicates a change in the set point, increased heat production, decreased heat dissipa­tion, failure of the regulatory systems, or any combination of those.
Record the patient’s temperature at each visit to establish a baseline for future reference. Deviations from this baseline are either fever or hypo­thermia. Scales on clinical thermometers are either Fahrenheit or Celsius. Conveniently remembered clinical equivalents are 35°C = 95°F, 37°C =
98.6°F, and 40°C = 104°F.
