Anesthetic Equipment

Question 1

Oscillometre Blood Pressure

Answer 1

Measures rise/fall from the cuff bladder to detect changes from pulsing artery beneath cuff
Measures systolic, diastolic and MAP

Question 2

ECG

Answer 2

Graphic representation of electrical activity of the heart as it travels through the conduction system/heart muscle
Differentiates normal/abnormal and dangerous/nondangerous rhythms

Question 3

Esophageal Stethoscope

Answer 3

Permits auscultation of the heart from a distance

Question 4

Pulse Oximetre

Answer 4

Estimates saturation of hemoglobin (SO2)
Expresses as a % of total binding sites
Determined oxygen saturation (SpO2)
Probe is sensitive to hemoglobin light absorption and blood pulsations (red/infrared)

Question 5

Capnograph

Answer 5

Measures amount of CO2 in inhaled/exhaled air
Sensor is usually at junction of ET tube and breathing circuit
Measures infrared light absorption

Question 6

Blood Gas Analysis

Answer 6

Assesses oxygenation and CO2 levels
Measures pH, dissolved O2, arterial CO2 (PaO2/PaCO2) and venous blood (PvO2/PvCO2)
Indicates oxygenation, ventilation, acid-base status
*via blood from an artery

Question 7

Doppler

Answer 7

Measures systolic pressure

Sends ultrasound waves that reflect back from pulsing artery (whoosh sound)
