Breathing discomfort

The flow field created within the protection zone depends mainly on the density difference between supply air and room air (Fig. 10.90). With vertical flow the supply air should be isothermal or cooler than ambient air. If it were warmer, the extension of the controlled flow would be reduced due to buoyancy effects, resulting in the supply air not reaching the operator s breathing zone. As the. supply air cannot be used for heating, the operator s thermal comfort should be maintained, preferably with radiant heaters in cold environments. If the supply air temperature is lower than the room air, the denser supply air accelerates down to the operator, and for continuity reasons the supply flow contracts. Excessive temperature differences result in a reduced controlled flow area with thermal discomfort, and should only be used in special cases. 

Notify die primary health care provider if any of tiie following occurs increased severify of chest pain or discomfort, irregular heartbeat, palpitations, nausea, shortness of breath, swelling of the hands or feet, or severe and prolonged episodes of light-headedness and dizziness. 

Lactic acidosis (buildup of lactic acid in the blood) may also occur with die administration of metformin. Although lactic acidosis is a rare adverse reaction, its occurrence is serious and can be fatal. Lactic acidosis occurs mainly in patients with kidney dysfunction. Symptoms of lactic acidosis include malaise (vague feeling of bodily discomfort), abdominal pain, rapid respirations, shortness of breath, and muscular pain. In some patients vitamin B12 levels are decreased. This can be reversed with vitamin B12 supplements or with discontinuation of the drug therapy. Because... 

The classic symptom of ACS is midline anterior chest discomfort. Accompanying symptoms may include arm, back, or jaw pain, nausea, vomiting, or shortness of breath. 

A casualty with known or potential exposure to carbon monoxide blood agents but who shows no signs of neurological or cardiac abnormalities, and does not complain of discomfort (e.g., headache, difficulty breathing, etc.). If available, breath measurement indicates that the blood carbon monoxide level is less than 10%. Anyone with potential exposure to metal carbonyls should be transported to a medical facility for evaluation because of the risk of latent chemical pneumonitis from inhalation of these agents. 

Signs and Symptoms Symptoms in immunocompromised individuals may include fever, difficulty breathing (dyspnea), nonproductive cough, bloody sputum (hemoptysis), bloody nose (epistaxis), a vague feeling of bodily discomfort (malaise), pneumonia, weakness, chest pain, and anorexia. May progress to inflammation of the eyes (endophthalmitis), sensitivity to light (photophobia), and/or inflammation of the heart (endocarditis). May also cause abscesses in the heart, kidneys, liver, spleen, other soft tissue, or the bone. If the central nervous system becomes involved, can cause altered mental states and seizures. 

Symptoms included nausea, vomiting, abdominal discomfort, diarrhea, giddiness, lassitude, headache, cough, and shortness of breath, and persisted for at least 2 h and sometimes 2 days. Serum nickel concentrations on day 1 after exposure were 286 (13-1340) pg/L vs. 50 pg/L in nonaffected workers for urine these concentrations were 5.8 (0.2-37.0) mg/L vs. 4.0 pg/L... 

The predominant symptom of ACS is midline anterior chest discomfort (most often occurring at rest), severe new-onset angina, or increasing angina that lasts at least 20 minutes. The discomfort may radiate to the shoulder, down the left arm, to the back, or to the jaw. Accompanying symptoms may include nausea, vomiting, diaphoresis, or shortness of breath. Elderly patients, patients with diabetes, and women are less likely to present with classic symptoms. 

Symptoms Anthrax can fool many victims as symptoms are quite non-specific namely fever, malaise, fatigue, cough, and mild chest discomfort followed by severe respiratory distress and labored breathing, profuse perspiration, harsh vibrating sounds during respiration, and bluish discoloration from lack of oxygenation in the blood. A patient can go into shock, and death can occur within twenty-four to thirty-six hours after onset of severe symptoms. However, in some instances, there can be a short period of seeming before the victim dies. 

In rats, the LDso for 4 hours was 1350 ppm. Behavior of the animals suggested irritation of the eyes, nose, and respiratory tract, with labored breathing. At necropsy, there were no discernible gross abnormalities of the major organs. In the same study, rats were exposed to methyl acrylate at 110 ppm 4 hours/ day, 5 days/week, for 32 days. There were no overt signs of central nervous system or respiratory effects, although the animals huddled with their eyes closed, possibly indicating some eye discomfort. 

When PTFE is heated to between 315°C and 375°C, the fumes cause influenza-like effects, including chills, fever, and tightness of the chest, that last 24-48 hours.Symptoms suggestive of pulmonary edema, including shortness of breath and chest discomfort, have been observed in a few instances. Although complete recovery usually occurs within 12 8 hours, a case of fatal acute pulmonary edema after exposure to the pyrolytic products of PTFE has also been reported. Presenting symptoms were cough, dyspnea, abdominal...

Infliximab intravenous infusions result in acute adverse infusion reactions in up to 10% of patients, but discontinuation of the infusion for severe reactions is required in less than 2%. Infusion reactions are more common with the second or subsequent infusions than with the first. Early mild reactions include fever, headache, dizziness, urticaria, or mild cardiopulmonary symptoms that include chest pain, dyspnea, or hemodynamic instability. Reactions to subsequent infusions may be reduced with prophylactic administration of acetaminophen, diphenhydramine, or corticosteroids. Severe acute reactions include significant hypotension, shortness of breath, muscle spasms, and chest discomfort such reactions may require treatment with oxygen, epinephrine, and corticosteroids. 

Cynanchum japonicum Moore et Decne. Bai Chen (root)50 No information is available in the literature. Antitussive, expectorant, for bad cold with cough and discomfort in the chest, asthmatic breathing, and acute bronchitis.
