Pulse Ox vs ETCO2

Pulse Ox; Oxygenation

I: Transport of O2 via the bloodstream to the cells

II: May take minutes to detect a change

ETCO2: Ventilation

I: Level of change at end of exhalation

II: A change is detecated w/in seconds

Requires a pulse to measure saturation

Info about O2 reading reaches the tissues

Indentifies trends

Detects changews earlier than what is observed

Correlates / resp assessment

What Pulse Ox measures

Zoll Monitor

I: The oxygen saturated in arterial blood

The zoll monitor will show

I: Digital readout

II: A waveform

Treat the patient, not the monitor

Look at the whole patient

-Two (2) sensors & a light source

-Uses the color of the blood to determine its oxygen content

I: Oxygenated blood (Brighter red)

II: Unoxygenated blood (Dark)

Sensor measures this difference

Conditions which may advertisly affect pulse oximetery readings

CO poisoning (increase)

Cigarette's (increase)

Cold extremities (decrease)

The 'Hypo's"

-Hypotension

-Hypovolema

-Hypothermia

High intensity light

Conditions that may affect Pulse Ox reading

Part II

High intensity light

Cardiac arrest

fingernail polish

medical condition

medications

excessive patient mvment (sivering /trembling)

95-100%: Normal

92-94%: 

<90%: Heading to life threating issues

<85%: Life threating

Pulse Ox: Ventilation

I: Transport O2 via the bloodstream to the cells

II: May take minutes to detect

ETCO2

I: Level of CO2 in the airway at the end of exhalation

A change detected w/in seconds

-Req's a pulse to measure saturation

-Information about O2 reaching the tissue

-Indentify's trends

-Detects changes earlier than observed

Correlates w/ resp assessment
