Sajulga , RNCarbon monoxide poisoning : Carbon monoxide poisoning An example of an inhaled poison The result of the inhalation of the products of incomplete hydrocarbon combustion May occur as an industrial or household accident or as an attempted suicideCarbon monoxide : Carbon monoxide Exerts its toxic effect by binding to circulating hemoglobin to reduce the oxygen-carrying capacity of the blood Combines with hemoglobin to form carboxyhemoglobin The affinity between carbon monoxide and hemoglobin is 200- 300x that between oxygen and hemoglobin As a result, tissue anoxia occurs.Primary assessment: Primary assessmentPowerPoint Presentation: Assess airway and breathing. Respiratory depression may be present. If the carbon monoxide poisoning is due to smoke inhalation, stridor (indicative of laryngeal edema due to thermal injury) may be present.Primary interventions: Primary interventionsPowerPoint Presentation: Provide 100% oxygen by tight-fitting mask The elimination half-life of carboxyhemoglobin , in serum, for a person breathing room air is 5 hours 20 minutes If the patient breathes 100% oxygen, the half-life is reduced to 80 minutesPowerPoint Presentation: 100% oxygen in a hyperbaric chamber will reduce the half-life to 23 minutes [treatment of choice Intubate, if necessary, to protect the airway.Subsequent assessment: Subsequent assessmentPowerPoint Presentation: A thorough history is important: determine the type and length of exposure as well as possible other fumes inhaled An underlying anemia, cardiac disease, or pulmonary disease may place a person at higher risk. Determine LOC —the patient may appear intoxicated from cerebral hypoxia; confusion may progress rapidly to coma.PowerPoint Presentation: Assess complaints of headache, muscular weakness, palpitation, dizziness. Inspect skin: may be pink, cherry red, or cyanotic and pale—skin color is not a reliable sign. Monitor vital signs: increased respiratory and pulse rates are generally present. Be alert for altered breathing patterns and respiratory failure.PowerPoint Presentation: Listen for rales or wheezes in the lungs (with smoke inhalation, indicates acute respiratory distress syndrome). Obtain arterial blood samples for carboxyhemoglobin levels. Normal is less than 12%. Severe carbon monoxide poisoning is present when levels are greater than 30% to 40%.General interventions: General interventionsPowerPoint Presentation: History of exposure to carbon monoxide justifies immediate treatment. GOALS: to reverse cerebral and myocardial hypoxia and hasten carbon monoxide elimination. Give 100% oxygen at atmospheric or hyperbaric pressures to reverse hypoxia and accelerate elimination of carbon monoxidePowerPoint Presentation: Patients should receive hyperbaric oxygen for CNS or cardiovascular system dysfunction. Use continuous ECG monitoring, treat dysrhythmias, and correct acid-base and electrolyte abnormalities. Observe the patient constantly—psychoses, spastic paralysis, vision disturbances, and deterioration of personality may persist after resuscitation and may be symptoms of permanent CNS damage.PowerPoint Presentation: Thank you You do not have the permission to view this presentation.
