The Importance of Mechanical Ventilators in Severe Lung Infections

In severe lung infections, the respiratory system is significantly compromised, making it difficult for patients to get enough oxygen into their bloodstream and remove carbon dioxide. This can lead to respiratory failure, a life-threatening condition where the body’s vital organs do not receive the oxygen they need to function properly. Mechanical ventilators, also known as […]

Enflurane Mechanism Action

Leave a Comment / Anesthesia / Dr Akif

Circulatory system and Enflurane Mechanism Action : Enflurane reduces BP due to vasodilatation as a result of decrease in SVR and cardiac depression. There is increase in heart rate and reduction in cardiac output. It does not sensitize the heart to catecholamines or stimulate the sympathetic nervous system. The margin between adequate anaesthesia and unacceptable hypotension

Arteriovenous Malformations AVMs

Leave a Comment / Anesthesia / Dr Akif

The reduced cerebrovascular resistance at the site of Arteriovenous Malformations AVMs lead to an increase in blood flow to this area and the formation of a lower resistance shunt along with peri-infarction oedema. They usually represent a high-flow and low-resistance shunts with systemic arterial pressure more than the vascular intramural pressure ; so, rupture does

One of the Sevoflurane cardiovascular effects is that the Sevoflurane has minimal effect on heart rate. There is a fall in systemic vascular resistance and blood pressure, but less than isoflurane. Also Sevoflurane cardiovascular effects are complex such as the pulmonary arterial pressure is also reduced. There is a lesser depression of left ventricular systolic

Blood Brain Barrier Functions

Leave a Comment / Anesthesia / Dr Akif

In normal Blood Brain Barrier functions the effective pore size of cerebral capillaries is 7-9 A°. This small pore size does not allow movement of small ions, i.e, Na, K and C1. Therefore, the fluid movement across the Blood Brain Barrier Functions is determined by the ‘total’ osmotic gradient, generated both by large molecules and

Trichloroethylene Trichloroethylene is also called as Trilene. It is an inhalational anesthetic gas, which was widely used until recently. It is still used in some developing countries because of its cheap cost compared to the other halogenated inhalational anesthetics. Trichloroethylene Physical Properties • It is colorless liquid. • Odor is sweet. • Mildly irritant. •

Boyle’s law

2 Comments / Anesthesia / Dr Akif

Boyle’s law is an important gas law that states that at a constant temperature, the volume of gas is inversely proportional to the pressure of the gas. This means that when the temperature of a gas is kept constant, the relationship between Volume and pressure of a gas is inverse. Another way to put tis law
