30 Questions
What is the difference between hypoxia and hypoxemia?
Hypoxia refers to inadequate oxygen supply in the tissues, while hypoxemia refers to an inadequate amount of oxygen in the blood
What is the primary cause of hypoxia in the tissues?
Deficient oxygen supply
What are the symptoms and signs of hypoxia?
Confusion, restlessness, shortness of breath, bluish discoloration, decreased level of consciousness, cough, difficulty breathing, decreased heart rate, palpitations, and sweating
Why is pulse oximetry essential in the operating room?
To detect and treat intraoperative hypoxemia
What is the risk of hypoxemia during anesthesia and operation?
Irreversible damage to the heart and brain
What is the primary goal of anesthesia staff during anesthesia and operation?
To avoid hypoxemia
What are the three potential causes of an obstructed airway that may lead to hypoxia during anesthesia?
Misplacement of the tracheal tube in the esophagus, aspirated vomit blocking the airway, and inadequate breathing.
What is the effect of severe bronchospasm on oxygen delivery to the lungs?
It prevents enough oxygen from reaching the lungs and also prevents carbon dioxide from being removed from the lungs.
What are the potential consequences of a pneumothorax on oxygen delivery?
It can cause the affected lung to collapse, preventing oxygen from reaching the alveoli.
How can anesthetic drugs contribute to hypoxia?
They can depress breathing and circulation, leading to inadequate oxygen delivery to the tissues.
What are the potential equipment-related causes of hypoxia during anesthesia?
Problems with the anesthetic equipment, oxygen supply, and monitoring equipment can all contribute to hypoxia.
What are the initial steps in managing hypoxia during anesthesia?
Checking if the airway is clear, looking for signs of laryngospasm, and ensuring the absence of vomit or blood in the airway.
What is the most common cause of hypoxia in theatre?
Airway obstruction
What can cause a previously well-saturated intubated patient to become hypoxic?
Displaced, kinked, or secretion-obstructed endotracheal tube
What can prevent oxygen from getting into the alveoli to combine with hemoglobin in the blood?
Bronchospasm, lung collapse, pulmonary edema, or pneumothorax
What can depress breathing in a patient?
Drugs such as opioids, poorly reversed neuromuscular blocking agents, or deep volatile anesthesia
Why is it essential to check the patient's circulation during management of hypoxia?
To ensure normal circulation and detect any signs of inadequate circulation, such as excessive blood loss or cardiac shock
How can inadequate circulation be revealed during management of hypoxia?
Through the pulse oximeter
What is a potential consequence of excessive Halothane administration?
Cardiac depression
What is the primary goal of managing hypoxia?
To restore oxygen in the blood to normal and keep the patient comfortable
What should be checked first when investigating a problem with oxygen delivery?
Obstruction or disconnection of the breathing circuit or tracheal tube
What should be done immediately when anaphylaxis occurs?
Stop giving the causative agent
What medications are administered in anaphylaxis management?
Adrenaline, Steroids, Bronchodilators, and Antihistamine
Why is it essential to check the anesthesia drugs before administration?
To ensure that all anesthesia drugs are given correctly
What is the primary method of treating hypoxia?
Oxygen administration
What is the purpose of mechanical ventilation in treating hypoxia?
Life support for patients who are very sick and cannot breathe
What is the importance of treating the underlying cause of hypoxia?
To address the root cause of hypoxia
What is the medical term for normal breathing?
Eupnea
What is the term for difficulty breathing during sleep?
Orthopnea
What is the term for shallow breathing?
Hypopnea
