EDN: Carbon Monoxide Poisoning

Inhaled poison

carbon monoxide poisoning is an example of what type?

incomplete hydrocarbon combustion

carbon monoxide poisoning is a result of inhalation of the products of _________

Carbon monoxide poisoning

it is a result of inhalation of the products of complete hydrocarbon combustion.

oxygen-carrying capacity of the blood

Carbon monoxide exerts its toxic effect by binding to circulating hemoglobin to reduce the

200 to 250

The affinity between carbon monoxide and hemoglobin is ________ times more than between oxygen and hemoglobin

soot on the back of hard palate or pharynx

What would be your assessment if carbon monoxide poisoning is due to smoke inhalation?

carboxyhemoglobin

Carbon monoxide combines with hemoglobin to form

Tissue Anoxia

WHAT IS THE RESULTING COMPLICATION OF CO poisoning?

Stridor

indicative of laryngeal edema because of thermal injury

hard palate or pharynx

Check for soot on the back of the _______ or _______if smoke inhalation is suspected.

Arterial blood

in ABG, what blood sample is taken, arterial or venous?

5 hours and 20 minutes

The elimination half-life of carboxyhemoglobin, in serum, for a person breathing room air is

80 minutes

If the patient breathes 100% oxygen, the half life is reduced to

25 minutes

100% oxygen in a hyperbaric chamber oxygenation (TREATMENT OF CHOICE) will reduce the half-life to

pink, cherry red, or cyanotic

how does carbon monoxide poisoned patient SKIN looks like?

Skin color

is not a reliable sign

12%

Normal NON-Toxic concentration of CO?

20%

TOXIC concentrations of CO poisoning are considered to be greater than ________

30-40%

in severe carbon monoxide poisoning, levels are greater than ____________??

rales or wheezes

In smoke inhalation, this indicates acute respiratory distress syndrome

to reverse cerebral and myocardial hypoxia

What is the GOAL for CO poisoning management?

Hyperbaric Chamber Oxygenation

TREATMENT OF CHOICE for CO Poisoning?

permanent CNS damage

Observe the patient constantly—psychoses, spastic paralysis, vision disturbances, and deterioration of personality may persist after resuscitation and may be symptoms of ______________

rales or wheezes

with smoke inhalation, this assessment indicates acute respiratory distress syndrome

Provide 100% oxygen using tight-fitting mask

If the hospital DOES NOT HAVE Hyperbaric chamber oxygenation, what is the substitute? That helps reduced CO poison half life to 80 minutes.

Hyperbaric Oxygenation Membrane

what is the machine called?

diabetic foot

Hyperbaric Chamber Oxygenation is also used to what complication?

3%

Normal carboxyhemoglobin levels for non-smokers should be less than _______ percent

laryngeal

In smoke inhalation, stridor may indicate _______ edema.

headache, dizziness, palpitation

A person exposed to CO may initially complain of _______ and muscular weakness.

Hyperbaric oxygen therapy

What is the treatment of choice to reduce carboxyhemoglobin levels rapidly?

skin color

Which clinical sign is least reliable when assessing CO poisoning?

intubate immediately

What should be done if a CO-poisoned patient is unconscious with airway compromise?

>20%

The carboxyhemoglobin level considered toxic is:

ARDS

The presence of wheezing and rales in a smoke inhalation victim suggests:

B. Eliminating oxygen from the body

The goal of CO poisoning management includes all EXCEPT:
A. Reversing myocardial hypoxia
B. Eliminating oxygen from the body
C. Monitoring cardiac rhythm
D. Correcting acid-base imbalances

A. Permanent CNS damage

Chronic CO exposure can lead to:
A. Permanent CNS damage
B. Asthma
C. Skin cancer
D. Hepatic failure
