Respiratory therapy
Respiratory therapy is the health profession focused on assessing breathing, supporting oxygenation and ventilation, managing airway and lung treatments, operating respiratory equipment, and helping people with acute or chronic cardiopulmonary problems.
What respiratory therapy is
Respiratory therapy is a clinical field focused on breathing and cardiopulmonary support. Respiratory therapists assess how well a person is moving air, exchanging oxygen and carbon dioxide, clearing secretions, using respiratory muscles, and responding to treatment. The field combines bedside care, technical equipment, patient education, emergency response, and long-term disease management.
Breathing as a clinical problem
Breathing problems can develop suddenly, as in asthma attacks, pneumonia, trauma, overdose, sepsis, heart failure, or respiratory failure. They can also be chronic, as in COPD, cystic fibrosis, neuromuscular disease, pulmonary fibrosis, sleep-disordered breathing, or recovery after severe illness. Respiratory therapy asks what support is needed now and what will help the person function better over time.
Assessment
Assessment may include respiratory rate, work of breathing, breath sounds, oxygen saturation, blood gases, cough strength, airway clearance, ventilator data, response to medicine, exercise tolerance, and the person's symptoms. Respiratory therapists also help perform or interpret pulmonary function testing, oxygen assessments, sleep-related testing, and other measurements that guide treatment plans.
Treatment and equipment
Treatment can include oxygen therapy, aerosol medicines, airway clearance, chest physiotherapy, noninvasive ventilation, invasive mechanical ventilation, artificial-airway care, humidification, suctioning, inhaled gases, pulmonary rehabilitation, patient teaching, and emergency airway support. The equipment matters, but so does matching the treatment to the person's diagnosis, goals, and safety needs.
Ventilators and critical care
In intensive care, respiratory therapists help manage ventilators that support or replace breathing. They monitor alarms, pressures, oxygen delivery, carbon dioxide removal, patient comfort, airway safety, and readiness to reduce support. Ventilator care is highly team-based because the same patient may also need sedation decisions, infection treatment, nutrition, mobility, family communication, and recovery planning.
Pulmonary rehabilitation
Respiratory therapy also supports people living with chronic breathing problems. Pulmonary rehabilitation may combine supervised exercise, breathing strategies, oxygen planning, education, nutrition guidance, energy conservation, and emotional support. The goal is not simply better test numbers; it is helping people walk farther, manage symptoms, avoid triggers, use medicines correctly, and do more of daily life.
Newborns, children, and transport
Respiratory therapists may care for premature newborns with fragile lungs, children with asthma or infection, adults after surgery, and critically ill patients during transport. These settings require careful attention to airway size, oxygen targets, ventilator settings, alarms, infection risk, family teaching, and rapid changes in condition.
Why it matters
Respiratory therapy matters because breathing problems can become dangerous quickly, but long-term lung disease can also quietly limit work, sleep, movement, and independence. Good respiratory care can stabilize emergencies, support recovery from severe illness, teach safer home management, and help people live with less fear around breathlessness.
