What does oesophageal stethoscope do
Allows more accurate auscultation of heart and resp. Sounds
Osophageal stethoscope checks (5)
Clean Secure connection Accurate measurement Damage Placement
What does pulse-ox do (3)
Measure O2 sat
- % O2 bound to HGB in arterial blood
Some display pulse
Assess CV and resp. Function
Pulse-ox checks (6)
Clean Calibrated Connections secure Probe placement Damage to leads Charged/battery use
What does ECG do (2)
Measures electrical activity across heart
- HR and rhythm
ECG checks (5)
Clean Calibrated Connections secure/placement Charged/plugged in/battery life Damage to leads
What does BP monitor do (2)
Measure BP and tissue perfusion
Methods of direct BP measurement (2)
IV cannula into peripheral artery
Central venous via cannula into jugular
What does central venous BP measure
Blood volume returning to heart
Methods of indirect BP measurement (2)

Doppler
Features of oscillimetric BP monitor and what it measures (3)
Cuff inflates/deflates automatically
Systolic, diastolic and mean arterial BP
Features of Doppler BP monitor and what it measures
Cuff inflated manually
Ultrasound probe placed over peripheral pulse connected to speaker
Systolic only
BP monitor checks (5)
Clean (cuff and probe) Damage Calibrated Connections secure Charged/battery life
What does capnograph do (2)
Measures end tidal CO2
- CO2 expired at peak exp.
Early detection of resp. Compromise
Types of capnograph (2)
Main unit
- placed between et tube and circuit
Side stream unit
- small gas sample diverted away from circuit to distant sensor
