Flow Volume Loops are more sensitive and informative in detecting pulmonary diseases than conventional spirometry. Modem microprocessor controlled recording spirometers automatically generate these flow volume loops. The following are the parameters that are assessed in the Flow volume loops. TV= Tidal volume IRV = Inspiratory reserve volume IC = Inspiratory capacity ERV = Expiratory reserve
Nitrous oxide inhalation anaesthetic is a gaseous inhalation agent first described in 1799 by Hamphrey Davy and introduced by Horace Wells (1846), a dentist, into clinical use in the US and it is still in use. Physical properties: Nitrous oxide inhalation anaesthetic is a colourless, sweet smelling and non-irritant gas, bp-88°C, slightly heaver than air.
Minimization of the risk of aneurysm rupture during Anesthesia for Cerebral Aneurysm demands smooth induction and maintenance of optimum transmural pressure (TMP) gradient. TMP is the difference between mean arterial pressure (MAP) and ICP. Rise in MAP or fall in ICP affects transmural pressure gradient thereby increasing the risk of rupture of the aneurysmal sac.
Desflurane muscle relaxation chemical depresses the neuromuscular junction, it decreases the force of contraction of muscles and increases fade. Endotracheal intubation is possible. There is a potentiation of nondepolarizing muscle relaxants similar to isoflurane. There have been no reports of malignant hyperthermia in man but has been seen in animals. It is advisable to avoid
Below is an answer to the simple question what is sleep? What is Sleep? Physiologically, sleep is regarded as absence of wakefulness, where the responses to environmental stimuli are greatly reduced. But, in fact, it is an active state, related to definite anatomic structures as well to specific biogenic amines. Yet, its exact mechanism is
Doxapram injection Doxapram is a specific respiratory stimulant. It stimulates the respiratory center preferentially and has relatively less effect on cortical and spinal sites. Following intravenous doxapram injection the drug stimulates ventilation and increases cardiac output and work. Doxapram dose It is given in a dose of 1-1.5 mg/kg by intravenous injection. Intravenous infusion can also
Fentanyl citrate injection is a potent narcotic analgesic and an opioid. It is said to be 100 times more potent than morphine and 1000 times more potent than pethidine. Fentanyl citrate injection effects It causes profound analgesia and sedation in a dose of 0.1 mg intramuscular. Like other narcotic analgesics it causes respiratory depression and is
Wong baker pain assessment tool is used in the patients who do not have appropriate cognitive level to use a number scale, like lay persons or children. The patient then points out to face best represents how he/she is feeling at that point of time. The patient must be explained correlation between each face and
Desflurane is an inhalational agent used in anesthesia that is similar to isoflurane except the chlorine atom of isoflurane is replaced by fluorine atom which produces significant changes in physical properties. Physical Properties of Desflurane : It is colorless liquid. Pungent odor, so induction is not pleasant. Vapor pressure of Desflurane is very high (681
IV Anesthesia or intravenous anesthesia is when anesthesia is given through a vein through injections. Anesthesia is usually started or induced with intravenous or IV anesthesia drugs. The different IV Anesthesia drugs are: Thiopental sodium Midazolam Methohexitone Ketamine Etomidate Propofol Some Steroids Ultra short acting barbiturates The ultra-short acting barbiturates administered as IV Anesthesia to
