Chief Complaint • The patient is a 49-year-old Caucasion female who complains of worsening dyspnea in the past few days
History of Present Illness • CC • HPI • PMHx • MEDS • Allergies • SocHx • FMHx • ROS • Physical Exam • Differential • LABS • Radiological • Diagnosis • Treatment The patient is a 49 year old caucasion female with a history of chronic obstructive pulmonary disease who presents to the ER after her PCP evaluated her with an oxygen saturation of 84%. The patient notes that she has become more short of breath since November and it has worsened in the past few days. This is apparent all day long and is worse with exertion. She notes that she feels better when she uses her boyfriends home oxygen. She also notes that her boyfriend is chronically tired and short of breath. At the time of her symptoms she denies having chest pain, palpitations, calf tenderness or recent upper respiratory infections. She was speaking really slow when examined but was alert and oriented x 3.

Next day they send someone to the house who finds carbon monoxide leak in oven.
Carbon Monoxide PoisioningBackground • Carbon monoxide (CO) • Colorless, odorless gas • CO is formed as a by-product of burning organic compounds • Fatalities result from • Fires • Stoves • Portable heaters • Automobile exhaust • Cigarette smoke is a significant source of CO • Improperly vented gas water heaters • Kerosene space heaters • Charcoal grills • Hibachis • Methylene chloride vapors
Carbon Monoxide PoisioningPathophysiology • CO toxicity causes • Impaired oxygen delivery and utilization at the cellular level • CO affects several different sites within the body • Most profound impact on organs with highest oxygen requirement • Brain • Heart • Method • CO reversibly binds hemoglobin • Relative anemia • Small concentration can have large affect • Result in significant levels of carboxyhemoglobin (HbCO). • Binds hemoglobin 230-270 times more avidly than oxygen • CO level of 100 ppm produces an HbCO of 16% at equilibration • CO binds to cardiac myoglobin • Greater affinity than to hemoglobin • Myocardial depression • HbCO level • Often does not correlate well with clinical status • Implies possible additional impairment of cellular respiration.
Carbon Monoxide PoisioningPathophysiology • HbCO levels often do not reflect the clinical picture • Levels • Around 10% • Beginning of symptoms • Headache • 50-70% • Seizure • Coma • Fatality • Elimination • CO is eliminated through the lungs • Half-life • 3-4 hours at room temperature • 30-90 minutes with administration of 100% O2 • 15-23 minutes with hyperbaric oxygen at 2.5 atm
Acute poisoning Malaise, flulike symptoms, fatigue Dyspnea on exertion Chest pain, palpitations Lethargy Confusion Depression Impulsiveness Distractibility Hallucination Confabulation Agitation Nausea, vomiting, diarrhea Abdominal pain Headache, drowsiness Dizziness, weakness, confusion Visual disturbance, syncope, seizure Fecal and urinary incontinence Memory and gait disturbances Bizarre neurologic symptoms, coma Cherry red rash Carbon Monoxide PoisioningHistory
Carbon Monoxide PoisioningPhysical • Vital signs • Tachycardia • Hypertension or hypotension • Hyperthermia • Marked tachypnea (rare; severe intoxication often associated with mild or no tachypnea) • Skin: Classic cherry red skin is rare (ie, “When you're cherry red, you're dead”); pallor is present more often. • Ophthalmologic • Flame-shaped retinal hemorrhages • Bright red retinal veins (a sensitive early sign) • Papilledema • Homonymous hemianopsia • Noncardiogenic pulmonary edema
Carbon Monoxide PoisioningPhysical • Neurologic and/or neuropsychiatric • Memory disturbance (most common) • Retrograde • Anterograde amnesia • Emotional lability • Impaired judgment • Decreased cognitive ability • Other signs include stupor, coma, gait disturbance, movement disorders, and rigidity.
Carbon Monoxide PoisioningLabs • HbCO • Elevated levels are significant • Low levels cannot exclude exposure • Up to 10% can be seen in smokers • CK-MB / Troponin • Ischemia can be associated • EKG • Sinus tachycardia
Carbon Monoxide PoisioningTreatment • 100% inspired oxygen • Sometimes can use hyperbaric O2 • Careful correction of acidosis • O2 is appropriate
