Laboratory

A) Obtain dosimetry reading from the victim's badge following an occupational exposure to estimate the exposure dose, if possible.
B) Monitor vital signs, pulse oximetry and respiratory function in patients at risk to develop pulmonary effects (ie, inhalation dose (exposure) of 50 ppm-min or above) or as indicated in patients with an unknown exposure.
C) In patients anticipated (ie, inhalation dose of 150 ppm-min or above or a suspicion of a high dose) to develop pulmonary edema, monitor vital signs every 15 minutes, frequent chest auscultation and assessment of respiratory function, continuous pulse oximetry, baseline arterial blood gases (repeat as indicated), and a baseline chest x-ray (repeat in 8 hours or as indicated).
D) Obtain a baseline CBC with differential, electrolytes, liver enzymes, and renal function following an exposure.
E) Monitoring fluid balance can be important in patients with evidence of pulmonary edema.
F) Monitor serum electrolytes as indicated, especially in patients that may receive diuretics.
