History

Review all medications Antihypertensives can cause significant hypotension, especially in the setting of volume depletion or over-diuresis. Anaphylaxis should be considered if the patient recently started on a new drug and presented with respiratory distress. Findings suggestive of hypovolemic shock Abdominal pain Diarrhea Dry skin, mucosa, axillae Hematemesis Hematochezia Melena Postoperative Trauma Vomiting Findings suggestive of cardiogenic shock Chest pain Dyspnea Palpitations Findings suggestive of distributive shock Altered mental status Chills Dyspnea Dysuria Fatigue Fever Flushing Headache Hematuria Malaise Myalgias Photophobia Productive cough Rash Tachycardia Tachypnea

Physical Examination

Vital signs Temperature Fever may suggest sepsis or anaphylactic reaction related to transfusion. Hypothermia may be associated with sepsis, adrenal crisis, or myxedema. Pulse Bradycardia or tachycardia can either be a primary or secondary process. Pulsus paradoxus may be seen in cardiac tamponade, pulmonary embolism, hemorrhagic shock, or tension pneumothorax. Pulsus alternans may be seen in heart failure, severe aortic insufficiency, or hypovolemic shock. Respiration Tachypnea commonly occurs in pneumothorax, sepsis, and cardiogenic shock. Hypopnea may be seen in narcotic or sedative overdose. Blood pressure Confirm arterial hypotension by checking blood pressure in both arms manually. Arterial line may be considered. Postural hypotension suggests volume depletion or autonomic dysfunction. Do not test orthostatic hypotension in hypotensive patients. Mental status Altered mental status may indicate inadequate perfusion to vital organs or use of sedatives or narcotics. Cutaneous Decreased skin turgor and dry mucous membrane signify dehydration. Cool extremities, clammy and mottled skin, peripheral cyanosis, and delayed capillary refill are commonly noted in cardiogenic shock and hypovolemic shock, whereas warm and moist skin may represent hyperdynamic phase of septic shock. Extensive burns and severe trauma may be evident on inspection and are associated with significant fluid loss. Hyperpigmentation may be an indicator of adrenal crisis. Neck Elevated jugular venous pressure (JVP) correlates with increased left ventricular end diastolic pressure (LVEDP) and decreased left ventricular ejection fraction (LVEF). Jugular venous distention or elevated JVP typically occurs in: Heart failure Tricuspid stenosis Pulmonary hypertension Superior vena cava obstruction Constrictive pericarditis Cardiac tamponade Kussmaul's sign Constrictive pericarditis Restrictive cardiomyopathy Tricuspid stenosis Superior vena cava obstruction Right ventricular infarction Abdominojugular reflux (a positive abdominojugular reflux correlates with a PCWP of 15 mmHg or greater) Cardiac tamponade Constrictive pericarditis Tricuspid insufficiency Inferior vena cava obstruction Heart failure (except for pure backward left-sided heart failure) Jugular venous pressure waveform Blunted y descent suggests cardiac tamponade or tricuspid stenosis. Steep y descent suggests constrictive pericarditis or severe tricuspid insufficiency.
