Confusion assessment method – Look for

2. difficulty focusing, and

3. disorganized thinking or

4. altered LOC-lethargy, stupor or hyper-alert for positive test

EdemaDiagnosis

Management
Pressure of 1-2 seconds with finger over bony prominence produces pitting for pitting edema, recovers easily – non-pitting edema- does not pit easilyPitting edema – hypo-proteinic states, CHF
Non pitting edema – lymphedema (may pit in early stages), inflammatory edema

Vital Signs
TemperatureDetect fever/hypothermia

Diagnosis

Prognosis
Rectal 0.4-05. C

Higher than oral.

Oral 0.4-0.7C higher than axillary Oral 0.4 C

Higher than tympanic membrane. Tympanic rapid, convenient reflects core temperature (falsely low if cerumen present)
Defined as 99th percentile of maximum temperatures in healthy person -37.7° C oral

Fever patterns – less useful in antibiotic/antipyretic era

Extreme pyrexia > 41.1C or, (<36.1 indicates poor prognosis in certain clinical conditions)
McGee, 2007, Chapter 16.

44
Respiration RateDiagnosis

Prognosis
Observation while patient unaware measurement being done for at least 30-60 secondsNormal rate averages 20 breaths per minute (range 15-25)
Tachypnea > 25
Bradypnea < 8
Fetor
McGee, 2007, Chapter 17.

Respiratory PatternCheyne-Stokes

Kussmaul’s
Alternating cycles of hyperpnea and apnea

Rapid deep breaths
Congestive heart failure, neurologic disorders

Metabolic
McGee, 2007, Chapter 17.

44
Blood PressureDiagnosis

Prognosis
In stable clinical situations to avoid misdiagnosis of hypertension – patient sits 5 minutes, arm at heart level, arm supported, appropriate cuff size (cuff bladder to encircle at least 80% arm), inflated to 20-30 mm HG above systolic pressure, released 2 mm Hg per second using bell or diaphragm
Average of 2 readings should be taken.

Hospitalized
Essential hypertension- three or more reading over three visits separated by weeks exceeds 140/90

Blood pressure difference between two arms approx 10 mm Hg. More than 20 mm Hg difference indicates subclavian steal or aortic dissection

Low leg BP in young hypertensive indicates coarctation of aorta

Hypotension – systolic BP <90 – increased in mortality in ICU

Systolic BP < 80-increased mortality in Myocardial infarction
McGee, 2007, Chapter 15.

Reeves, 1995.

Pulse OximetrySuperior to cyanosis as a sign in detecting hypoxemiaMeasurement on earlobe or finger tipIndicates the degree of oxygen saturation of haemoglobin, not affected by haemoglobin concentrationMcGee, 2007, Chapter 18.
