Anatomy and Physiology

Determination of Clotting Time

Clotting time is defined as the time interval in between onset of bleeding and appearance of semisolid mass i.e. clot. Normal value of clotting time is 3-4 minutes.

Measurement of Respiratory Dead Space

The Dead space is the volume of breath that does not participate in the gas exchange and is the ventilation of the lungs without perfusion.

Calculation of Body Surface Area (Using a Nomogram)

The surface area is determined when a straight line connecting the patient’s height and weight crosses the BSA column. The aim of the experiment is to calculate body surface area using normogram

Preparation and Staining of Bone Marrow Smear

The semi-solid tissue found in the spongy or cancellous portions of bones is called as bone marrow. The contents are hemopoietic cells, marrow adipose tissue and supportive stromal cells.

Demonstration of Pure Tone Audiometry

The pure tone audiometry is the testing of hearing sensitivity of subject to pure tones. This helps in diagnosis of types of hearing loss namely conductive deafness, sensorineural deafness or mixed deafness
