  Artificial respiration

Artificial respisration is the restoration or initiation of someone's breathing by manual, mechanical, or mouth-to-mouth methods.

 • Artificial respiration is required whenever there is an arrest of breathing , without cardiac failure.

 • Purpose of artificial respiration is to ventilate the alveloi and to stimulate the respiratory centers.

Methods of artificial respiration are of two types

 1. Manual methods



 Manual methdos can be applied quickly without waiting for the availability of any mechanical aids.

 Affected person must be provided with clear air . Clothes around neck and chest regions must be loosened. Mouth, face and throat should be cleared of mucus, saliva , foreign particles etc. Tounge must be drwan forward and it must be prevented from falling posteriorly.

 Manual methods are of two types:-

 i. Mouth- to - mouth methods : In this methods , subject should put on supine position and resuscitator kneels at side of subject.Resucitator should keep thumb at mouth and pull lower jaw , close nostril of subject with other hand. Resuscitator should take deep breath and keep mouth on mouth of subject and exhales all the air to subject.

 This procudure is repeted 12 to 14 times per minute, till normal breathing start.

 ii. Holger Nielsen method (or Back Pressure Arm Lift method ) : In this method subjct is placed in Prone position,.and his hands near the chick . And pressure is applied on back of subject. This method is repeted 12 times per minute.

 2. Mechanical methods

This method is used when the subject needs artificial respiration for long periods. Mechanical methods are of two types :

 i. Drinker method :- The machine used in this method is called iron lung chamber or tank respirator.

 ii. Ventilation Method:- A rubber tube is insert into the trachea of the patient through the mouth. Apparatus used for ventiliation is called ventilator. It is used to treat acute respiratory failure. Ventilator are of two types- Volume ventilator, and Pressure ventiltor.

Contents [hide]  Shock  Definition- Systemic hypoperfusion owing to reduction in either cardiac output or in the effective circulating blood volume. Shock- clinical features Hypotension Tachycardia Cold clammy skin Rapid shallow respiration. Drowsiness.  confusion, irritability Multi organ failure. Classification  Cardiogenic shock –  myocardial pump failure – Intrinsic myocardial damage (infarction), vent. Arrhythmias,  extrinsic comopression (cardiac tamponade) or outflow obstruction (pulmonary embolism). Hypovolemic shock –  loss of blood or plasma volume-  by h’hage, fluid loss from severe burns or trauma. Septic shock –  systemic microbial infection most commonly in gram negative infectns(endotoxic shock) ,can occur with gram +ve & fungal infectns Neurogenic shock- anaesthetic accident or spinal cord injury.

 name differnt vitamins , symptoms of difiency of vit D, Vit K 10mark VITAMINS:- (2 mark) Vitamins are defined as "Small organic molecules present in diet which are required in small amounts "  • most of the vitamin are not synthesized in the body and hence they most be supplied in the diet.  • however, few provitamins are present in the body , which are converted to vitamins. types of vitamin: Vitamins are divided into two groups  1. Fat soluble vitamins  • Vitamin A  • Vitamin D  • Vitamin E  • Vitamin K  2. Water soluble vitamins  • Vitamin B complex  • Vitamin C Vitamin A (5 Mark)  • They are retinol (vitamin A alcohol), Retinal (vitamin A aldehyde) and retinoic acid (Vitamin A acid).  • in nature vitamin A occurs in two forms.  a. retinolesters- in the food of animal origin.  b. carotenes- in plant foods as provitamin.  • in the intestine, pancreatic esterase hydrolyzes retinolesters present in the ...
