The patient presented 2 months after his injury with progressive stridor and dyspnea necessitating tracheostomy. A computed tomographic scan of the neck revealed stenosis extending from the vocal cords to the top of the sternum. [ncbi.nlm.nih.gov]
Resuscitation and initial reviews are done there before admission to the burn unit if the burns occurred within 24 hours of presentation, or to the general wards if the burns occurred more than 24 hours before presentation. [woundsresearch.com]

Clinically mustard exposures present with dyspnea and wheezing from the pulmonary standpoint. Symptoms are often delayed for hours to days after initial exposure, but subclinical changes occur earlier. [clinicaladvisor.com]
- Rales
Note rhonchi, rales, wheeze and use of accessory muscles of respiration. Facial burns show nearness to the fire. Other burns demonstrate an inability to escape. [patient.info]
Auscultation may reveal a variety of findings, such as absent or diminished sounds, wheezing, rales (crackles) or rhonchi. [emsworld.com]
Hypoxia, rales and rhonchi occur only in those with the most severe injuries. 1 An admission chest X-ray is also a poor predictor, but is important for the baseline of evaluations. 6, 24 Figure 1 An algorithm to manage the patients at risk for inhalation [dovepress.com]

Although some authors reported that bronchial wall thickening was sometimes found on initial chest radiographs, patients with inhalation injuries often have a normal chest radiograph at initial stages. 38 In contrast, the presence of pulmonary infiltrates [dovepress.com]

That can mean a delay in seeking medical help and starting treatment. The worse the victim is burned, the worse the smoke inhalation symptoms are likely to be. [walkuplawoffice.com]

Epidemiology Due to lack of consistent diagnostic methods, the incidence of inhalation injury from all chemical irritants is not readily available. [clinicaladvisor.com]
A further 19% were due to a combination of burns and being overcome by gas or smoke. [ 1 ] Epidemiology [ 2, 3 ] A study from North West England found that the overall admission rate to hospital for smoke inhalation or burns was 0.29/1,000 population [patient.info]

Prevention
How can smoke inhalation be prevented? To prevent fires, make sure that electrical wiring, chimneys, wood stoves, and space heaters are working properly. Use flammable liquids safely and store them in a locked area out of the reach of children. [uhs.berkeley.edu]
The results of this study underscore the need for early diagnosis of inhalation injuries and prevention or treatment of associated life-threatening complications. [woundsresearch.com]
You can take steps to try to prevent inhalation injuries: At home, practice fire safety, which includes preventing fires and having a plan in case there is a fire If there is smoke from a wildfire nearby or lots of particulate pollution in the air, try [medlineplus.gov]
Medical intervention can help restore function or at least prevent additional damage. [vanderwalde.com]
All were back to work, except for two who continued to need artificial airways. [ 27 ] Prevention The prevention of smoke injury is largely the prevention of fire but, if it does occur, then early warning is necessary. Smoke detectors save lives. [patient.info]
