  • Respiratory Adjustments – Anatomy, Mechanism, Functions

    Respiratory Adjustments/Acclimatization is the process of adjustment that the respiratory system makes due to chronic exposure to a high altitude. Over a period of time, the body adjusts to accommodate the lower partial pressure of oxygen. The increase in muscular work and metabolic rate associated with exercise necessitates both elevated 02 uptakes by the gills (M02) and enhanced

  • Breathing Control – Anatomy, Mechanism, Functions

    Breathing control its main function is to send signals to the muscles that control respiration to cause breathing to occur. The ventral respiratory group stimulates expiratory movements. The dorsal respiratory group stimulates inspiratory movements. The control of ventilation refers to the physiological mechanisms involved in the control of breathing, which is the movement of air into and out of the lungs. Ventilation facilitates respiration. Respiration

  • Exchanging Oxygen and Carbon Dioxide

    Exchanging Oxygen and Carbon Dioxide/Gas exchange is the process by which oxygen and carbon dioxide move between the bloodstream and the lungs. This is the primary function of the respiratory system and is essential for ensuring a constant supply of oxygen to tissues, as well as removing carbon dioxide to prevent its accumulation. In the original

  • Gas Exchange – Mechanism, Functions and More

    Gas exchange is the process by which oxygen and carbon dioxide move between the bloodstream and the lungs. This is the primary function of the respiratory system and is essential for ensuring a constant supply of oxygen to tissues, as well as removing carbon dioxide to prevent its accumulation. In the original sense of the Latin

  • Gas Laws – Principle, Types, Purpose, Procedure

    The gas laws are a group of physical laws modeling the behavior of gases developed from experimental observations from the 17th century onwards. While many of these laws apply to ‘ideal’ gases in closed systems at standard temperature and pressure (STP), their principles can still be useful in understanding and altering a significant number of

  • Spirometry – Indications, Contraindications, Procedure

    Spirometry is a simple test used to help diagnose and monitor certain lung conditions by measuring how much air you can breathe out in one forced breath. It’s carried out using a device called a spirometer, which is a small machine attached by a cable to a mouthpiece. Spirometry is one of the most commonly used approaches

  • Pulmonary Function Tests – Indications, Contraindications

    Pulmonary function tests (PFTs) are noninvasive tests that show how well the lungs are working. The tests measure lung volume, capacity, rates of flow, and gas exchange. This information can help your healthcare provider diagnose and decide the treatment of certain lung disorders. Pulmonary function tests (PFTs) allow physicians to evaluate the respiratory function of their patients. They are reproducible and accurate. Ultimately, the results of

  • Non-Respiratory Functions of Lungs

    Non-respiratory functions of lungs/These nonrespiratory functions of the lung include its own defense against inspired particulate matter, the storage and filtration of blood for the systemic circulation, the handling of vasoactive substances in the blood, and the formation and release of substances used in the alveoli or circulation. Non-respiratory functions of lungs  In addition to their functions in

  • Tests of The Shoulder Joints and Physical Examination

    Tests of The Shoulder Joints and Physical Examination  (PETS) are clinical examination maneuvers designed to aid the assessment of shoulder complaints. Despite more than 180 PETS described in the literature, evidence of their validity and usefulness in diagnosing the shoulder is questioned. The complex structure of the shoulder, with its variable pathological conditions of rotator

  • Positive End-expiratory Pressure

    Positive end-expiratory pressure (PEEP) is a value that can be set up in patients receiving invasive or non-invasive mechanical ventilation. This activity reviews the indications, contraindications, complications, and other key elements of the use of PEEP in the clinical setting as relates to the essential points needed by members of an interprofessional team managing the

  • Hypoxia – Causes, Symptoms, Diagnosis, Treatment

    Hypoxia is a state in which oxygen is not available in sufficient amounts at the tissue level to maintain adequate homeostasis; this can result from inadequate oxygen delivery to the tissues either due to low blood supply or low oxygen content in the blood (hypoxemia). Hypoxia can vary in intensity from mild to severe and
