EDN: Carbon Monoxide Poisoning

Inhaled poison

carbon monoxide poisoning is an example of what type?

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

carboxyhemoglobin

Carbon monoxide combines with hemoglobin to form

Tissue Anoxia

WHAT IS THE RESULT 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 and pal

how does carbon monoxide poisoned patient SKIN looks like?

Skin color

is not a reliable sign

20%

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

30-40%

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

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.
