Final answer:
Cricoid pressure is used to prevent regurgitation during induction of anesthesia but is controversial due to questions about its efficacy and risk. Body pressures are crucial indicators typically monitored invasively in critical settings; routine blood pressure measurements are done non-invasively. Experts recommend using cricoid pressure based on clinical judgment instead of making it a standard practice.
Step-by-step explanation:
The routine use of cricoid pressure, also known as the Sellick maneuver, has been a topic of debate in medical practice. It is a technique used during rapid sequence intubation to prevent regurgitation of stomach contents into the upper airway, which can be a critical concern during the induction of anesthesia. However, its routine use is controversial due to the lack of consensus on its effectiveness and potential risks.
Body pressures measurements are often crucial medical indicators and are usually monitored during surgery or for patients in intensive care using invasive methods, such as catheters. In contrast, routine blood pressure measurements are non-invasive and are carried out using an inflatable cuff on the upper arm, which detects blood flow below the cuff, and the pressures are transmitted to a mercury-filled manometer.
The current consensus among experts in anesthesia and emergency medicine is to apply cricoid pressure based on clinical judgment, considering the potential risks and benefits, rather than as a universally mandated standard for all patients undergoing anesthesia.
