Pulmonology is the branch of medical sciences which deals with the study of the respiratory system. It also covers the study of the normal physiology of our respiratory system, diseases of lungs and respiratory tract and the treatment of these diseases based on the clinical and laboratory diagnosis.
The respiratory system as we all know begins from the nasal cavity, includes the nasopharynx, trachea, bronchi uptil the alveoli present in the lungs. Actual gaseous exchange occurs between the membranes of alveoli and blood vessels. The proper functioning of our respiratory system is based on proper anatomy of the respiratory tract and the fact that the lifestyle of human beings greatly affects the normal physiology of the lungs and the rest of the respiratory tract.
Oxygen, a must for human life is supplied to our bodies by the respiratory system.
Oxygen is something we can’t live without. We need oxygen at the metabolic level to provide us with the fuel that we need for all the functions in our bodies. Lungs are the organs which are responsible for oxygen supply. This oxygen then reaches the tissue level and serves as a source of metabolic reactions occurring everywhere in the human body.
Diagnosis of lung diseases
With the passage of time and when we street our lungs too much, the oxygenation becomes poor and results in gradual decline and organ function. This happens in many diseases of the lungs. Some of the diseases require prompt diagnosis and treatment and can threaten life if we don’t take timely actions.
Lung volumes are always evaluated whenever a patient enters a pulmonologist’s room. By lung volumes, we mean tidal volume, total lung capacity, dead space, etc. These tests give us a holistic picture of the lung condition due to which a patient seeks medical help. Apart from the lung volumes that are measured by a spirometer, pulse oximetry and simply, the respiratory rates tell us the picture of the disease.
Pulse oximetry is a simple test by which we check the oxygen saturation of the lungs. It is a digital device that gives the level of oxygen saturation of the blood at any given time. Normal oxygen saturation is 100% and ideally must be maintained at this level. Patients with oxygen saturation of less than 90 are critical and need prompt attention.
Pulse oximetry is done in every ward, ER, ICU everywhere in the hospital and proper charts are maintained for its evaluation. Sometimes it is measured along with the vital signs.
Pulse oximetry tracker
As mentioned earlier, the oxygen saturation of patients is measured at regular intervals especially for an indoor patient, postoperative patient after anesthesia and patients coming to emergency after accidents or severe injuries.
So, a proper record is maintained like the vital records and is evaluated at regular intervals. Low oxygen saturation at any point of time needs attention and quick management. The pulse oximetry tracker contains the name of the patient and the percentage of oxygen saturation at any time. Some columns are assigned for the time below which the values are written.
