What is Carbon Monoxide ● Chemical symbol – CO ● Colorless ● Odorless ● Tasteless ● “Silent Killer ● “Great Imitator”

Carbon Monoxide Poisonings ● 6, 000 fatalities annually in US. ● 40, 000 -50, 000 people seek ED care for CO related problems annually. ● Often called “Silent Killer, ” CO’s initial symptoms are often vague, subtle and easily misdiagnosed.

Causes of Carbon Monoxide ● Incomplete combustion of carbon Carboncontaining fuels. ○ Home heating oils ○ Charcoal ○ Kerosene ○ Coal ○ Gas

Common CO Poisoning Sources ● Faulty Furnaces, heaters ● Auto exhaust ● Gas generators ● Charcoal grills used indoor ● Tobacco smoke ● Fires ● Small gas engines or equipment ● Gas appliances ● Gas heaters in enclosed areas

Pathophysiology ● CO is 200 -250 times more desirable that Oxygen to RBC’s. ● CO readily displaces oxygen from the hemoglobin and forms a compound called carboxyhemoglobin, which does not carry oxygen. ● Carboxyhemoglobin is delivered to cells in place of oxygen resulting in tissue hypoxia. ● Creates suffocation type of environment at cellular level.

Factors that Affect Severity ● Amount of carbon (concentration) ● Time (duration) ● Activity level (during exposure) ● Health ● Age

Who is at Risk? ● Specific Occupations (Fire & EMS) ● Elderly ● Children ● Infants ● Pregnant mothers ● People with existing health problems

Signs & Sympotms ● Headache ● Dizziness ● Weakness ● Nausea ● Vomiting ● Chest Pain ● Altered LOC ● Flu-like ● Coma ● Death

Signs & Sympotms (cont. ) ● Suspect Carbon Monoxide poisoning when: ○ Several symptoms are reported at the same time. ○ No other cause can be identified. ○ More than one person at scene reports similar symptoms/onset.

Nervous System Effects ● Even low-level exposure to carbon monoxide results in long-term impairment of higher cognitive functions such as memory, new learning ability, attention, and concentration. ● Effects may mimic a stroke (The great Imitator) ● Coma and Brain death

Cardiovscular System Effects ● Hypotension ● Tachycardia ● Dysrhythmia’s ● Myocardial Ischemia ● Symptoms may mimic an MI ● Ultimately Ventricular Fibrillation

Scene Safety ● Rescuer safety is #1 priority ● Never Enter hazardous scene without proper PPE. ● Evacuate occupants/victims ● Ventilate as needed

Detection ● Pulse Oximeters can not detect CO ● Rad-57, non-invasive and continuous method of detecting Carbon Monoxide in patients. ○ Detects carboxyhemoglobin levels ○ Detects oxyhemoglobin levles ○ Obtains pulse rate ○ Small, handheld battery operated ○ Finger clamp similar to a pulse oximeter.

Detecting CO in seconds with Rad 57 C ● The Masimo Rad 57 C is the only FDA-approved Pulse CO-Oximeter that noninvasively and continuously monitors Carbon Monoxide levels in the bloodstream in seconds. EMS professionals can quickly and easily diagnose carbon monoxide poisoning on the scene. Just slip the sensor on the patient’s finger and press a button. The Masimo Rad 57 C accurately detects the percentage of Carbon Monoxide in the bloodstream in just seconds, allowing for prompt and possibly life saving treatment.

Rad 57 Guidelines ● Any patient with suspected carbon monoxide poisoning should receive oxygen via NRB mask. ● The RAD-57 C may be used as a screening tool for ASYMPTOMATIC potentially exposed people: ○ If there is a CO alarm in a residence, the RAD-57 C may be used to test for levels on the occupants of the location. ○ Any asymptomatic patient with a level of greater than 15% should receive oxygen for 30 minutes, then reassess the patient.

Rad 57 C Guidelines (cont. ) ● The RAD-57 C may be used as a screening tool for SYMPTOMATIC patients: ○ If there is a CO alarm in a residence, the RAD-57 C may be used to test for levels on the ill occupants of the location. ○ Carbon monoxide poisoning does not have specific, clear cut symptoms, and other medical conditions may present with dizziness, nausea or confusion. ○ All symptomatic patients should be transported, regardless of RAD-57 C level.

Suggested Triage Algorithm Measure Sp. CO 0 -3% No further medical evaluation of Sp. CO needed Sp. CO >3% Loss of consciousness or neurological impairment or Sp. CO >25% ? No Yes Transport on 100% oxygen for ED evaluation. Consider transport to hospital with hyperbaric chamber Sp. CO >12 Sp. CO <12 Transport on 100% oxygen for ED evaluation Symptoms of CO exposure? Yes Transport on 100% oxygen for ED evaluation No No further evaluation of Sp. CO needed. Determine source of CO if nonsmoker

BLS Treatment ● Remove patient from environment ● Apply high-flow oxygen ● Obtain SAMPLE history ● Complete an assessment ● Obtain vital signs ● Use Rad 57 C if available ● Transport to most appropriate facility

ALS Treatment ● Re-Assess LOC & vital signs ● Evaluate respiratory system ● IV ● EKG monitoring ● Use Rad 57 C, if available ● Transport to most appropriate facility

Specialized Treatment ● Hyperbaric oxygen treatment (HBO) may be recommended if Sp. CO >30 and/or the patient is unconscious, has altered mental status, or the patient is pregnant. ● Follow local protocols for guidance.

Understanding PPM & Sp. CO PPM or “Parts Per Million” is the atmospheric concentration of the gas PPM is common fireground safety measurement, often misleading as CO forms in pockets Sp. CO - noninvasive measurement of CO in the blood Sp. CO as measured by RAD-57 is a function of PPM CO and total time of exposure of the poison Age, health and respiratory rate may be a factor Even low PPM levels can lead to high Sp. CO if exposure is long enough, common in overhaul Even an exposure of 50 PPM for 60 minutes requires assessment and possible medical treatment with oxygen
