Timeline of respiratory therapy

Timeline of Respiratory Therapy

The Timeline of Respiratory Therapy traces the development of Respiratory Therapy, a healthcare profession specializing in the treatment, management, diagnosis, and care of patients with deficiencies and abnormalities associated with the respiratory system. This timeline highlights significant milestones, discoveries, and innovations that have shaped the field from its inception to the present day.

Ancient Times

The history of respiratory therapy dates back to ancient times when various methods were used to clear airway obstructions and support breathing.

• c. 1500 BCE - The Ebers Papyrus, an ancient Egyptian medical document, describes the use of herbal remedies believed to treat respiratory conditions.
• c. 400 BCE - Hippocrates, often considered the "Father of Medicine," describes the use of tracheotomy to maintain an open airway in cases of airway obstruction.

19th Century

The 19th century saw the development of mechanical devices to aid breathing and the establishment of the scientific basis for respiratory care.

• 1837 - John Dalziel invents the respirator, a device designed to assist breathing.
• 1858 - George Fell introduces the Fell respirator, an early mechanical ventilator to support respiration in patients.

20th Century

The 20th century was a period of rapid advancement in respiratory therapy, marked by technological innovations and the formalization of the profession.

• 1928 - The iron lung, a type of negative pressure ventilator, is introduced to treat patients with poliomyelitis-induced respiratory paralysis.
• 1943 - The development of positive pressure ventilators during World War II provides a more effective means of ventilatory support.
• 1947 - The Inhalation Therapy Association, now known as the American Association for Respiratory Care (AARC), is founded, marking the formal beginning of the profession.
• 1955 - The introduction of intubation and mechanical ventilation in the treatment of polio patients.
• 1960s - The development of Pulmonary Function Testing (PFT) equipment allows for the detailed assessment of lung function.
• 1970s - Advances in critical care medicine and the establishment of Intensive Care Units (ICUs) increase the demand for respiratory therapists.
• 1980s - The introduction of Pulse Oximetry revolutionizes the monitoring of patients' oxygen saturation levels.

21st Century

The 21st century continues to see innovations in respiratory therapy, particularly in the areas of disease management and ventilatory support.

• 2001 - The use of Non-Invasive Ventilation (NIV) becomes widespread, offering an alternative to intubation for certain patients.
• 2009 - The H1N1 influenza pandemic underscores the critical role of respiratory therapists in managing respiratory emergencies.
• 2020 - The COVID-19 pandemic brings unprecedented challenges to the field, with respiratory therapists at the forefront of treating patients affected by the virus.

Future Directions

The future of respiratory therapy is likely to see further technological advancements, including the use of artificial intelligence (AI) in patient monitoring and the development of more sophisticated ventilatory support systems. The ongoing research into respiratory diseases and their treatment will continue to shape the profession.
