Capnography is the monitoring of the concentration or partial pressure of ... a sudden drop in PETCO2 may indicate the patient has lost pulses and CPR may need to be ...
Hypocapnia also results in bronchoconstriction [3] in order to decrease ventilation. This mechanism is meant to counteract hyperventilation, and decrease the amount of oxygen coming into the lungs. The body's "goal" is to have a relatively even ratio of the partial pressure of oxygen to the partial pressure of carbon dioxide.
Acute respiratory acidosis occurs when an abrupt failure of ventilation occurs. This failure in ventilation may be caused by depression of the central respiratory center by cerebral disease or drugs, inability to ventilate adequately due to neuromuscular disease (e.g., myasthenia gravis, amyotrophic lateral sclerosis, Guillain–Barré syndrome, muscular dystrophy), or airway obstruction ...
Hyperventilation is irregular breathing that occurs when the rate or tidal volume of breathing eliminates more carbon dioxide than the body can produce. [1] [2] [3] This leads to hypocapnia, a reduced concentration of carbon dioxide dissolved in the blood.
Colorimetric capnography is a qualitative measurement method that detects the presence of carbon dioxide (CO2, a relatively acidic gas) in a given gaseous environment. From a medical perspective, the method is usually applied by exposing litmus paper/film to an environment containing a patient's airway gases (i.e. placing it into their breathing circuit/airway circuit), where it will then ...
In respiratory physiology, the ventilation/perfusion ratio (V/Q ratio) is a ratio used to assess the efficiency and adequacy of the ventilation-perfusion coupling and thus the matching of two variables:
A passenger has told NBC News of the dramatic incident that saw people aboard a Boeing flight thrown into the ceiling, as authorities probed what caused the plane's sudden mid-air plunge.
Central to implementing therapies to reverse or mitigate a state of respiratory compromise is an accurate diagnosis of the condition. Correctly diagnosing respiratory compromise requires a screening to determine the amount of gas in the patient's bloodstream.
