First Responders Save Three Patients and One Dog After Near-Fatal Carbon Monoxide Poisoning in Lexington Park

August 31, 2019

On Saturday, August 31, 2019, at approximately 7:40 a.m., emergency medical personnel responded to the 46700 block of Planters Court in Lexington Park, for the reported unconscious subject after a fall.

The 911 caller stated a 50 year-old female was unconscious after a fall, and that a second patient was now unconscious with the caller going in and out of consciousness. Due to the answers and details the caller gave, the 911 Emergency Communications Center upgraded the assignment and dispatched firefighters from Bay District, along with fire and emergency medical personnel from NAS Patuxent River to the residence for the possible carbon monoxide detector with symptoms.

Crews arrived on the scene to find a one-story split foyer residence with nothing evident. Firefighters attempted voice contact at the locked front door, and were about to force entry into the residence when a semi-conscious female was able to unlock the door and was pulled out by firefighters.

Within 5 minutes of arriving on the scene and entering the residence one adult male was found unconscious in a bedroom, one adult female was found unconscious in the bedrooms bathroom, and one small dog was found vomiting and semi-conscious in the hallway.

All three patients and the dog were rescued from the residence and placed into the waiting hands of emergency medical personnel for care. Firefighters then re-entered the residence to search for the cause and to conduct a secondary search of the residence. Crews found a running vehicle in the attached garage, with the garage door closed.

The vehicle was reportedly running since late Friday night when one of the occupants arrived home and forgot to turn the vehicle off.

Three adult patients were transported to Millison Plaza where Maryland State Police Helicopters Trooper 2, and Trooper 7 transported them to an area trauma center with severe carbon monoxide poisoning. The residence and dog were placed into the hands of the St. Mary’s County Sheriff’s Office and Animal Control.

Health effects and symptoms from Carbon Monoxide (CO) are based on the different levels and length of exposure as well as the patients age and health condition. The concentration of CO is measured in parts per million (ppm). The exposure of CO in the range from 1 to 70 ppm are uncertain but most people will not experience any noticeable symptoms. As the level of CO rises, and remains above 70 ppm, symptoms become more noticeable and patients may have headaches, fatigue, and nausea. As CO levels increase even more to above 150 to 200 ppm, the concentration can become deadly if its persistent and patients will have disorientation, unconsciousness, or even death.

When firefighters first entered the residence, they received readings over 1,680 ppm in the house, and over 1,000 ppm in the basement.

Updates will be provided when they become available.

    What? Came home late Friday night. Forgot to turn off the car?! Read that again.

      I too thought, “How?”…until we bought a new, ‘push button start’ vehicle with ultra quiet engine & exhaust. I am not the daily driver and have twice gotten out of the vehicle (in the garage… middle of the day!) with it running…and I am a ‘car guy’! Once I realized it as I was standing next to it, the other my wife did. I think it’s the fact keys don’t need to be pulled to enter the house. I see modifications coming in the future, as this is happening more & more.

        I agree. I recently bought a push to start and have gotten out of it without turning it off. Mine beeps once I’m far away, but if I pulled up in my garage and set the keys down on the kitchen counter, I wouldn’t be far enough for the car to beep. I can understand how this happened, especially if someone was tired just getting off work. It’s reckless to make these assumptions about people. Give them a break, they’ve been through enough.

          Please remain anonymous!

          That way at least your families will be spared the embarrassment of their association with people so stupid they can’t remember they need to turn off their car engines after parking their cars.

          Intelligence has sharply declined as technology has increased.

          A lot of these new cars, with the emissions requirements and small displacement engines, are VERY quiet when running. My car beeps very loudly at me when I shut the door with the vehicle running and the keys outside the car. All vehicles need some sort of alert when you leave the car running. Especially these new vehicles that you can’t even tell are running unless you look at the tachometer.

      Attached garages and guns need to be banned! Too many people have died from these senseless instruments of death.

    We know these people. How do we establish contact with them to help? Not enough detail in article to be able to help if needed. Do not care about the circumstance as it is the people that count. Please consider giving these folks a break while realizing many folks responded because they may believe in the value of others as well. Thank-you for allowing us to reach out and try to get a handle on ways to help. Do not normally respond to snarky responders but this is to “gimmeabreak”. Perhaps the poster was unaware the name and statement could hurt the recovery of others should they read them at a later date. Perhaps the article is not fully accurate as written. Please withold judgement and if you do not have something productive to say then please be quiet.

      The wonderful thing about America is that you don’t have to read the comments section. You don’t have to go to this site, pickup your device or even connect to the internet. People in America also get to express their feelings. It’s wonderful here in America. If you prefer to be controlled, please seek asylum in the People’s Republic of China, the Democratic People’s Republic of Korea or the Republic of Cuba.

        Thank you Patriot!

        You are soooo correct in your assertions.

        I am also sick of these PC namby=pambies who are so worried about possible “hurt feelings” but not concerned with the constitutional rights of red blooded Americans, like our freedom of speech!

        If folks are too dumb to turn off their car when they get out of it –

        they need to be rebuked openly, to save not only their own lives, but those of others who read about their “near-death by negligence” experience.

        This moddy-coddling is one thing, but don’t tell people what they can and can’t say!

        • the home owner on September 6, 2019 at 6:23 pm

          hey you whoever you are I am the homeowner so if you think I need to be rebuked say it to my face. other wise just shut up

          • Coast Guard Vet on September 9, 2019 at 5:13 am

            Says “the homeowner.” If you are the homeowner and a Navy veteran as the Petty Officer flag stipulates in the pictures, you’re a dumbass. You almost killed your family.

        Don’t you see how St. Mary’s County folk worship the lives of dogs?

        They don’t even care about the people!

        They want action immediately on sparing the family dog from the fears of the strange shelter.

        have they inquired of the condition of the residents? HELL NO!

  6. Gimmie on September 1, 2019 at 1:03 am

    well I am one of the ones in the house, this was a unfortunate accident and let me tell you this, the Fire Dept. Police, Life Flight were top of the line professionals I can honestly say they saved our lives. we all got to Baltimore Shock Trauma Hospital in a twenty minute flight, went through 2 rounds in the hyperbaric chamber. finally got home at 1 am. Gimmeabreak accidents happen are you perfect

    • Just a concerned individual on September 1, 2019 at 2:50 pm

      I’m so happy that someone was able to call 911. First responders, all of them, were your lifesavers for sure. I have a friend who has a new vehicle. And so far two times I had to ask if she had turned the car off. Also we were inside a restaurant and a woman asked if any of us owned a specific car and told her the car was still running. I would think, in my mind only, that if that “device” in the car can be disabled, do so. I remember her saying there is no alarm when you leave it running as you don’t need the key. I’m assuming I’ve said this correctly.
      God bless all of you for making it out of there alive. I know we are supposed to have carbon monoxide detectors in our house and batteries checked often. I will definitely check mine at this time. Before daylight savings time.
      Take care and I hope you have no after effects.

    Fantastic job, first responders!!! Thank you for serving our community. You are awesome!!!

    • Gimmie on September 1, 2019 at 10:57 am

      absolutely I was the guy they gave CPR to and I am here to talk about how good of a job they did

  8. LOOOL on September 1, 2019 at 9:13 pm

    LOOOL, what a little snowflake.You’re way more worried about their pet that is obviously safe now than the actual people affected. I bet you voted for Hillary ,too. You know im right.

    • YOU ARE RIGHT! on September 5, 2019 at 8:18 am

      Yepper – IDIOTS abound!

      So worried about the dog and couldn’t care LESS about those people!


  9. Meme on September 3, 2019 at 2:02 pm

    I have a push start car, and if I leave my car with the key while it is running it will alarm immediately. I just have to step out of the door. I haven’t (yet) left my car running. I’m sure it is possible though. I’m glad all are okay.

    • Not always on September 4, 2019 at 7:33 am

      Only if you leave the vehicle…taking the FOB with you. If the FOB is left in the vehicle, the vehicle doesn’t know you left.

      Like Fred Flintstone!

  10. Great. Now cost will go up even more. on September 5, 2019 at 8:15 am

    So sad.

    So now auto manufacturers will be forced to install some type of “alarm for idiots” that goes off anytime the car is running un-occupied.

    That will drive up the pricing another couple hundred.

    People are so stupid they just don’t deserve the nice things we have.

    • Anon on September 5, 2019 at 8:22 am

      Most FOBs do generate a beep when leaving the vehicle with engine still on.

      But most idiots never read their vehicle’s owner’s manual –

      so they don’t even know what that sound means!
