Q.6:richest source of vit.d??
answr cud have been unequivocally fish liver oil if it was there in the options...but the options mentiond FISH and not FISH OIL and if u refer to yhe table in PARK u will c that it has separate values for fish and fiah oils............and going by d same table,since fish oils isn't in d options,most appropriate answr shud b meat.................plz clarify.......

Reference: Dated February 26, 2007
The table may not come in a proper format. Please correlate....
Table 1: Boston University vitamin D analysis
Raw Fish (3.5 oz serving)
International Units (IU)
Wild Salmon (species unspecified)
[snip]
Ahi Tuna
404
Farmed Trout
388
Bluefish
280
Farmed Salmon*
245
Cod
104
Gray Sole
56
Mackerel
24
Other sources of vitamin D**
International Units (IU)
Cod Liver Oil, 1 Tablespoon
1,360
Tuna Fish canned in oil, 3 oz
200
Milk (fortified), 1 cup
[snip]
1 Whole Egg***
20
Beef liver, cooked, 3.5 oz
15
Swiss Cheese, 1 oz
12
I see that even if fish oil is eliminated in the options, fish itself is a strong contendor.

d)infrared end tiidal CO2 |
Vidyasagar has given the ans as a) for the centrineurxial block Q
and Capnography for the next Q(ref: textbook of aneasthesia , Ronald, 5th ed, vol 1 pg 1273)
answer impedence pulmonometry
refrence farnoff and martin neonatal and perinatal medicine 8th edition
Many devices are available for estimating airflow in infants. Noninvasive devices can be used for extended periods, yielding qualitative measurements of airflow that are sufficient for cardiorespiratory monitoring. However, quantitative measurements currently require a more invasive device such as a pneumotachometer, a hot wire anemometer, or an ultrasonic flowmeter for precise analysis of pulmonary mechanics.
The pneumotachometer is the gold standard for quantitative measurement of airflow. The basic design consists of a resistive element, such as a mesh screen or other material, inserted between two cylinders. As air flows through the resistive element, a pressure drop occurs that can be calibrated to output in units of flow. The flow signal can then be integrated to obtain Vt. To accurately measure flow, all air must pass through the pneumotachometer. Thus, in a ventilated patient the pneumotachometer can be attached to an endotracheal tube; leaks can be minimized by using a cuffed tube or gentle pressure applied to the neck. The difference between inspiratory and expiratory volume is the amount of gas leaked. In a spontaneously breathing infant, the pneumotachometer must be incorporated into a nasal or oral mask that is tightly sealed around the patient’s nose and mouth.[78]
During clinical practice the most common qualitative method of measuring airflow is impedance monitoring[/b]. [b]Impedance is measured using two electrodes placed on either side of the chest. Impedance monitoring is based on the principle that air has a much higher level of impedance than tissue. Using a very small current passed through the body, the electrodes can detect increases in impedance as the air-to-tissue ratio changes when air enters the lung during an inspiratory effort. Although impedance has minimal ability to quantify actual breath amplitudes when compared with the pneumotachometer,[74][81] it can detect the absence of airflow and thus the occurrence of central apnea. However, because air can move back and forth within the chest wall cavity during airway obstruction, impedance cannot distinguish obstructive apnea versus normal respiration.
Qualitative measurements of airflow can also be made at the nose via a thermistor or an end-tidal CO2 analyzer. The thermistor detects increases in temperature as warm air from the body crosses the sensor during expiration, whereas during inspiration air from the atmosphere cools the sensor back to room temperature. The end-tidal CO2 analyzer, which measures the level of CO2 during expiration, can also be used as a flow-sensing device. Although both end-tidal CO2 and thermistor devices have been used to document hypopnea,[119][135] both correlate poorly with Vt magnitude.[85][136] However, these devices can be used in conjunction with impedance monitoring to further characterize central versus obstructive apnea.
so neumotachometer is gold standar but it requires intubation
and as you can read impedence method is most commonly perfored.and does not requier e tube.
etco2 and thermistor technique is less useful than impedence.pls morgan says etco2 and capnograpy can be best used with measurement from et tube.
so answr is impedence. |

AIIMS
nov2002-
All of the following are risk factors for development of chorioCA following evacuation of H. mole except-
1. beta HCG greater that 40,000 iu.
2. uterine size more than 12wks
3. thyrotoxicosis
4. presence of bilat. theca leutin cysts
should the ans be 2 or 3?
pls someone answer

hi megh..the ans is "b" i.e. uterine size more than 16 wks..its not 12 wks as us have written...its 16 wks in the q...the ref is dutta obstetrics 6th edn page 197....he's given the criteria for invasie mole going into choriocarcinoma..in that is mentioned uterine size more than 20wks is the risk..not 16 wks...chek out..good luck..

guys all the best for AIIMS
. got new amit ashish.i am happy that most of the answers in this thread(baring hardly 2-3 questions) are exatly ame as per ashish amit.so i can say that i have not misguided anybody to the best of my abilities.
once again all the best for AIIMS
.
i will be starting new thread of the same kind after nov.2007 for nov.2007.
till then best of luck.
and i am extremely sorry if some mistakes are there in this thread. all the best.
