A deep breath is taken to fill the lungs about 75 per cent, and held for two or three seconds. Breathing out is forceful and slow which helps to move the mucus from the smaller to the larger airways. A normal urge to cough at this point is repressed, and the breathing pattern is repeated a few times. A strong cough then follows to expel the ...
Most protocols recommend first encouraging the patient to cough, and allowing them an opportunity to spontaneously clear the foreign body if they are coughing forcefully. If the person's airway continues to be blocked, more forceful maneuvers such as hard back slaps and abdominal thrusts (Heimlich maneuver) can be performed.
After positioning in which the patient sits upright with their arms at the side, with the chest clear of clothing, the four stages of the examination can be carried out. In order to listen to the lungs from the back the patient is asked to move their arms forward to prevent the scapulae (shoulder blades) from obstructing the upper lung fields.
SponTaneous Respiration using IntraVEnous anaesthesia and High-flow nasal oxygen (STRIVE Hi) is an open airway technique that uses an upwards titration of propofol which maintains ventilation at deep levels of anaesthesia. It has been used in airway surgery as an alternative to tracheal intubation. [99]
Generally, full mechanical ventilation is only used if a very deep state of general anaesthesia is to be induced, and/or with a profoundly ill or injured patient. Induction of general anaesthesia usually results in apnea and requires ventilation until the drugs wear off and spontaneous breathing starts. In other words, ventilation may be needed ...
Hyperpnea is distinguished from tachypnea, which is a respiratory rate greater than normal, resulting in rapid and shallow breaths, but not necessarily increasing volume in breathing. [1] Hyperpnea is also distinguished from hyperventilation , which is over-ventilation (an increase in minute ventilation ), which involves an increase in volume ...

Chronic obstructive pulmonary disease (COPD) is a type of progressive lung disease characterized by chronic respiratory symptoms and airflow limitation. [8] GOLD 2024 defined COPD as a heterogeneous lung condition characterized by chronic respiratory symptoms (dyspnea or shortness of breath, cough, sputum production or exacerbations) due to abnormalities of the airways (bronchitis ...
