inhalar

Inhalar is a verb in Spanish meaning to draw air, gas, or vapor into the lungs through the nose or mouth. Inhalation, or inhalación, is the process by which air and substances are taken into the lungs as part of respiration. In everyday language, inhalar is used to describe breathing in air, smoke, scent, or medication.

Etymology and usage: Inhalar is formed from Latin elements meaning into and to breathe, and it has cognates in other Romance languages. The noun form inhalación denotes the act or result of inhaling. The term is used in medical, scientific, and everyday contexts, often paired with phrases that specify what is being inhaled.

Physiology: Inhalation is one phase of respiration in which the chest cavity expands and air is drawn into the airways. Air travels through the nasal or oral passages, larynx, trachea, and bronchi to the alveoli where gas exchange occurs. The depth and rate of inhalation influence how much air and any inhaled substances reach the lungs.

Medical context: Inhalation therapy delivers medications directly to the lungs via devices such as inhalers. Common devices include metered-dose inhalers (MDIs), dry powder inhalers (DPIs), and nebulizers. Inhalation therapy is used for conditions like asthma and chronic obstructive pulmonary disease (COPD). Effectiveness depends on the suitability of the device and the user's inhalation technique.

Safety and public health: Inhalation can support treatment but also pose risks when exposure involves pollutants, smoke, or toxic chemicals. Reducing harmful inhalation exposures, using protective equipment, and monitoring air quality are important in occupational and environmental health.
