Dispatched around 1600 to a respiratory at 406 XYZ street, which is in the middle of HUD Housing and Cracktown.
Arrive on scene with fire behind and paramedic superivor pulling in third. Get out and realize that the house I am in front of is 408, and next one up is 410. Look back and realize I passed the address because I didn't think it would be the address- because it is a tented house.
"S-t, (partner), this is a respiratory to a tented f-king house."
Homeless person waves me down and walks us back to the back duplex, also tented, to find a 30-35 y/o female supine on the ground, one foot still inside the tent of the duplex, RR40+, combative, hypoxic, mild cyanosis, coughing. When asked, she reports that she fell asleep in the house around 1000 and that the company tented the house on her. Info tag on the tent states the chemicals and that it was tented at 1045. Supervisor on phone with poison control. Immediately tell her I know she is lying to my face, that they would not tent a person in a house, all companies do walk-troughs before sealing a tent, and that I know she broke in, and I need to know when she went inside. Homeless bystanders of course know nothing and claim they don't know the patient. She again sticks to her story. PD arrived and identifies her as a well known drug addict/prostitute/homeless. Place her on capno cannula and FFs help us move her to the stretcher and away from the building. Place on monitor, obtain 12-lead, sinus tach, no acute changes, RR 46, spo2 low 90s, capno in the 40-50s, LS wheezing.
Load into truck and have difficulty getting IV due to heavy track marks. Supervisor clears fire and they leave. He states poison control reports that the chemical is a respiratory irritant and be cautious of coughing, airway swelling, dyspnea, stridor, pulmonary edema, and respiratory failure; also reported effects are worse with longer exposure.
Secure 18g and am about to transport, check LS- flash pulmonary edema. Place CPAP and transport emergency for respiratory poisoning, myself driving, partner attending. PD follows behind emergency. Arrive to hospital where pt RR has decreased but she is still combative and trying to remove CPAP mask. Instruct her to leave it on because she will likely die without it, and she stops. Cop asks her a question as stretcher is removed from ambulance, and gets a coherent answer. Drop wheels and roll into ER, approx 60 feet from ambulance straight to ER bed. Turn and start DCing off monitor as partner is starting report, and see that pts head is bowed- unresponsive. Look at the cardiac monitor- Asystole. Check carotid- nothing.
"(Partner)! Check a pulse- monitor shows Asystole!"
Confirmed cardiac arrest, ripped off CPAP, moved to bed, worked in the ER for 15 minutes before confirmed. Hospital claimed we didn't recognize CA and were treating improperly; our EKG, BP, capno waveform, and SPO2 all have positive readings up until a full minute after arriving at the hospital. Partner had mild respiratory irritant from off gassing, in process of venting and deconing truck, my face, neck, and arms burn and itch, with coughing and burning chest. Supervisor, crew, and fire all questioned why hazmat response not called. All responders able to stay at work with no further health issues. Room in ER quarantined for 48 hours.
Lesson of the story: don't break into a tented house, you will die.
