The woman may have fluid slowly collecting in the lungs in a process known as pulmonary edema. During an eclamptic seizure, it is possible for a person to vomit the contents of the stomach and to inhale some of this material in a process known as aspiration. If aspiration occurs, the woman may experience difficulty breathing immediately or could develop an infection in the lungs later, called aspiration pneumonia. It is also possible that during a seizure breathing will stop temporarily or become inefficient, and the amount of oxygen reaching the womans body and brain will be decreased (in a state known as hypoxia). If it becomes difficult for the woman to breathe, she may need to have her breathing temporarily supported by an assistive device in a process called mechanical ventilation. In some severe eclampsia cases, the mother may become weak and sluggish (lethargy) or even comatose. These may be signs that the brain is swelling (cerebral edema) or bleeding (intracerebral hemorrhage). Risk factors
Eclampsia, like pre-eclampsia, tends to occur more commonly in first pregnancies than subsequent pregnancies. Women who have long term high blood pressure before becoming pregnant have a greater risk of pre-eclampsia. Patients who have gestational hypertension and pre-eclampsia have an increased risk of eclampsia. Furthermore, women with other pre-existing vascular diseases (diabetes or nephropathy) or thrombophilia disease such as the antiphospholipid syndrome are at higher risk to develop pre-eclampsia and eclampsia. Having a placenta that is enlarged by multiple gestation or hydatidiform mole also increases risk of eclampsia.
Also, poor hand-washing and inadequate disinfection of respiratory devices cause cross-infection and are important factors. Pathogenesis
Most nosocomial respiratory infections are caused by so-called microaspiration of upper airway secretions, through inapparent aspiration, into the lower respiratory tract. Also, "macroaspirations" of esophageal or gastric material is known to result in HAP. Since it results from aspiration either type is called aspiration pneumonia.Although gram-negative bacilli are a common cause they are rarely found in the respiratory tract of people without pneumonia, which has led to speculation of the mouth and throat as origin of the infection. Diagnosis
In hospitalised patients who develop respiratory symptoms and fever, one should consider the diagnosis. The likelihood increases when upon investigation symptoms are found of respiratory insufficiency, purulent secretions, newly developed infiltrate on the chest X-Ray, and increasing leucocyte count. If pneumonia is suspected material from sputum or tracheal aspirates are sent to the microbiology department for cultures. In case of pleural effusion, thoracentesis is performed for examination of pleural fluid. In suspected ventilator-associated pneumonia it has been suggested that bronchoscopy or bronchoalveolar lavage is necessary because of the risks of incorrect clinical diagnoses. Differential diagnosis
Atelectasis
Congestive heart failure
Pulmonary embolism

Treatment
Usually initial therapy is empirical. If sufficient reason to suspect influenza, one might consider oseltamivir. In case of legionellosis, erythromycin or fluoroquinolone.A third generation cephalosporin (ceftazidime) + carbapenems (imipenem) + beta lactam & beta lactamase inhibitors (piperacillin/tazobactam)
