Propane inhalation may create symptoms such as coughing, nausea, dizziness, nervousness, vomiting, increased heart rate, weakness, fever and lightheadedness, according to MedlinePlus. Higher levels of propane exposure can lead to convulsions, loss of consciousness, limb pain and numbness. It is important to seek medical attention after being exposed to propane.
Propane inhalation is dangerous because the gas overcomes the presence of oxygen in the lungs and strains or completely inhibits a person's ability to breathe correctly, notes MedlinePlus. A person who inhales propane gas must be moved to fresh air as soon as possible, and the individual's symptoms should be monitored for improvement. If no changes occur, emergency medical attention must be sought immediately.
Oxygen therapy is likely to be administered in a hospital while the patient's vital signs are watched carefully, and medical staff may elect to pull blood work to measure the extent of the patient's poisoning. Immediate medical attention is likely to save a patient, but waiting too long to call 911 can result in stroke, coma or death. MedlinePlus explains that propane is equally as harmful if ingested, in which case it helps to supply milk or water to a patient until medical help arrives. However, this is not advisable for patients who are having difficulty swallowing.
