Lecture 30: Peri-anesthesia monitoring and complications-IV Flashcards
What do you check to monitor patients oxygenation
- SPO2
- Pulse rate
- Change in SV
What does SPO2 tell you
Oxygenation
What does pulse rate tell you that ECG does not
If the heart is actually beating
What is a normal PaO2
95 (80-100)mm Hg
What is normal SaO2
98 (95-100) %
What is normal PvO2
45 (40-45) mm Hg
What is normal SvO2
75 (70-75)%
What is the ideal maintenance of SPO2
95%
What is the minimum for SPO2
90%
SPO2 is an estimate of ___
SaO2
What is the definition of hypodermic
PaO2 <60mm Hg
A PO2 of 60mmHg is equal to __SO2%
90%
How do you assess accuracy of SPO2
- Waveform- constant/ good waveform
- Pulse rate/rhythm matches actual HR or PR
What can affect reliability of pulse ox
Motion, pigment, tissue perfusion, thickness of tissue
Where do you place pulse ox probe
Tongue, lips, toes, toe nails
If pulse ox not working what can you apply to tongue and what does it do
Dry cause- cushioning effect- prevent collapsed capillary
