A lot of anesthetic gases can be dangerous when used in a low alveolar ventilation anesthesia. This is because the anesthetic gases can combine with soda lime or other components of the boyles machine and produce poisonous gases. It is also known as low flow anesthesia where low fresh gas flow is set in a closed circuit or a semi closed […]
Some of the Sevoflurane respiratory effects include that there is no irritation to the airway, least among inhalation agents, this makes it suitable for inhalational induction, the low blood/gas solubility aids faster induction. Sevoflurane respiratory effects include respiratory depression, reduces minute ventilation, tidal volume and ventilatory response to CO2. Sevoflurane abolishes hypoxic pulmonary vasoconstriction in
Introduction to Long-Term Venous Access Long-term venous access is a vital component of modern medical treatment, allowing healthcare providers to administer therapies over extended periods. This method is particularly significant in scenarios requiring frequent or continuous access to the bloodstream, such as chemotherapy for cancer patients, dialysis for those with kidney dysfunction, and long-term antibiotic
What is Tidal Volume? Tidal volume (VT) is a fundamental parameter in respiratory physiology, representing the amount of air that is inhaled or exhaled during a typical breathing cycle. It is a crucial aspect of pulmonary function that aids in understanding an individual’s respiratory health. Tidal volume is measured in milliliters (mL) and varies among
General Anesthesia mask is used to ventilate the patient without intubation or before intubation. The mask significantly increases amount of dead space. These are available in sizes from 0 to 4 numbers. Face mask should be made of antistatic rubber. At the bottom of General Anesthesia mask there is air filled cuff which has soft cushioning effect.
The endotracheal tube position should always be confirmed because the correct placement of the tube is essential for proper ventilation of a person. If the endotracheal tube position is not correct within no time the patient can become hypoxic due to the unavailability of oxygen to the lungs. The tube may be wrongly placed in
The reservoir bag is also called as the Breathing bag. The bag is attached to anesthesia breathing circuits to ventilate the patient. The bag acts as a reservoir for anesthetic gases as well as for oxygen, which when pressed results in the delivery of the gases or oxygen to the patient. An anesthetized and paralyzed
Autonomic dysreflexia is an acute syndrome that frequently occurs in spinal cord injury (SCI) patients with a level usually above T6. It is characterized by excessive unmodulated sympathetic outflow in response to noxious stimuli below the spinal cord level. This can lead to dangerous elevations of blood pressure with disastrous clinical sequelae. Pathophysiology of Autonomic
Introduction to Pediatric Weight Calculation Calculating the body weight of pediatric patients is a crucial skill for healthcare providers, particularly in emergency situations. Accurate weight estimation not only facilitates proper medication dosing but also ensures appropriate fluid administration. To streamline this process, guidelines from both the Pediatric Advanced Life Support (PALS) program and the World

The diaphragm function is the most important determinant of the depth of respiration especially the inspiration. The Diaphragm is the muscle that separates the thorax from the abdomen. It is a thin sheet like muscle that has the right and the left crura. The diaphragm act as a partition between the two major cavities of the
