knowledge concerning the physiology of breathing dates back to the 17th century. Before that time‚ the ideas in vogue about why and how we breathe were mystical and strange. Hippocrates “counted air as an instrument of the body”. Galen‚ whose influence on medical thought and progress was immense for many centuries‚ enunciated the doctrine of Hippocrates and formed his own doctrine based on observation. In the Galenic

Lab I OXYGEN CONSUMPTION Oxygen consumption (VO2) is the amount of oxygen taken up and utilized by the body per minute. The oxygen taken into the body at the level of the lungs is ultimately transported by the cardiovascular system to the systemic tissues and is used for the production of ATP in the mitochondria of our cells. Because most of the energy in the body is produced aerobically‚ VO2 can be used to determine how much energy a subject is expending. VO2 can be reported in absolute

This assignment describes my own reflective experience while caring for a sick neonate with Respiratory Distress Syndrome (RDS) in the neonatal unit. This has enabled me to explore the meaning and significance of my clinical practice and to recognise the complexities within it. The experience raises a number of issues frequently encountered in daily nursing practice. Within this assignment‚ I will be discussing a particular pre term baby with RDS and critically analyse the use of nasal continuous

The assessment method used in this case is the Airway‚ Breathing‚ Circulation‚ Disability‚ Exposure (ABCDE) approach. Thim et al (2012) suggests that the aims of this approach are to provide the patient

involve gas exchanges between the lungs and the atmosphere. For instance‚ pulmonary ventilation‚ or breathing involves the inhalation and exhalation of air between our lungs and the atmosphere. External respiration is the exchange of gases across the respiratory membrane between the alveoli and the blood in the pulmonary capillaries. This is where the capillaries gains O2 and loses CO2. And finally‚ the Internal respiration is the exchange of gases between the blood in the systemic capillaries and tissue

Learning Objectives: To define the following terms: ventiliation‚ inspiration‚ expiration‚ forced expiration‚ tidal volume‚ expiratory reserve volume‚ inspiratory reserve volume‚ residual volume‚ vital capacity‚ forced expiratory volume‚ minute respiratory volume‚ surfactant‚ and pneumothorax. To describe the role of muscles and volume changes in the mechanics of breathing. To understand that the lungs do not contain muscle and that respirations are therefore caused by external forces. To explore

The human body cells need oxygen in order to function and the respiratory system allows this to happen. Consisting of air passages‚ pulmonary vessels‚ the lungs and breathing muscles‚ it supplies fresh oxygen to the blood which can be fed to other parts of the body. The ribs‚ rib muscles and diaphragm all play a part in allowing air into and out of the lungs‚ (oxygen going into the body and carbon dioxide leaving the body). This is known as ventilation. When we breathe in we inhale and when we

pharynx spread into her sinuses? The infection in Cari’s nasal passages and pharynx was able to spread into her sinuses due to the sinuses being a drainage area for the nasal passages. B) What is the cough reflex? Describe the process that Cari’s respiratory system is using to clear her lungs by coughing. The cough reflex is used to clear sputum and irritants that are in the nasal passages and pharynx. There are cilia in her trachea that is moving mucus up from the lungs. When the mucus becomes abundant
