All about nosocomial asthma

Asthma is a medical condition of the respiratory system that manifests itself through hyperactivity of the respiratory system that results in inflammation and obstruction of the airways due to cellular hyper-reactivity. Both chronic and acute asthma present through shortness of breath, report shortened breaths and elevated pulse.

Asthma pathology

The pathophysiological mechanisms of asthma include bronchoconstriction and obstruction of the airways. This is due to the effect of edema that occurs in the airways as a consequence of a series of cellular inflammatory reactions, the cells that are involved are lymphocytes, mast cells, eosinophils, neutrophils, macrophages, resident cells and epithelial cells together with other mediators. inflammatory diseases recruited by the body in response to a foreign antigen, but unfortunately it becomes an overly cellular response.

In the asthmatic condition, a phenomenon is observed in the arterial blood gas pattern, where variations in the concentration of arterial carbon dioxide in the blood: PaCO2 and changes in the levels of Ph in the blood are used as an indication of the severity of the asthmatic condition. This is the rise in PaCO2 and the drop in Ph levels during an asthma attack. To a certain degree where the lungs cannot exhale more carbon dioxide from the lungs due to the obstruction of the airways, an increase in PaCO2 in the blood occurs and consequently a decrease in Ph levels. blood levels below the standard levels of 7.4, as the asthmatic condition worsens.

Factors that contribute to acute and chronic asthma include environmental factors such as environmental exposure to allergens and smoke; also areas prone to respiratory infections are contributing factors. Allergens are known to trigger the body’s immunity, causing the cellular immune mechanism to unfold. .

First aid advice for an asthmatic patient.

The first indication of an asthma attack is commonly a shortness of breath that is characterized primarily by difficulty breathing with difficulty. The patient may later become immobilized and convulse if the situation is not handled and the patient dies. Once a person has been identified as having an asthma attack, follow the tips below.

  • Sit them down and allow them to lean forward slightly to create more space in the lungs for smooth breathing.

  • Eliminate the allergen or move the person away from the triggering cause, this can be away from dusty, smoky or cold places.

  • Help the patient take their asthma medication, such as using the inhaler or taking antihistamine medications.

  • Seek medical help if the patient shows no improvement.


Asthma is a common condition that can be easily controlled, and having more information about it can go a long way in saving lives. The early diagnosis of the disease allows its treatment and, therefore, the mitigation of its severity.
