Effectiveness of Video Assisted Teaching Programme on Knowledge Regarding Care of Children on Mechanical Ventilator among Staff Nurses Working in Pediatric Intensive Care Units of Selected Hospitals at Belgaum”

Abstract

Background: Mechanical ventilation is a technique for assisting or replacing natural breathing. This may include using a ventilator, or having a physician or other appropriate individual compress a bag or a collection of bellows to assist breathing. Negative-pressure ventilation, in which air is simply drawn into the lungs, and positive-pressure ventilation, in which air (or another gas mix) is squeezed into the trachea, are the two types of ventilation. Because of the anatomy of the human pharynx, larynx, and esophagus, as well as the circumstances under which ventilation is needed, additional measures are often required to "protect" the airway during positive pressure ventilation in order to enable adequate passage of air into the trachea while avoiding air entering the esophagus and stomach.

Method: This was pre-experimental study a total of 500 subjects was selected through non-probability convenient sampling technique. Pre-experimental one group pre-test, post-test design was used. Data was collected by structured knowledge questionnaire. Data collected under the 2 sections (socio-demographic data, knowledge questionnaires). The reliability of the tool was established by spilt half method formula. The reliability result of knowledge was r = 0.902829. Video assisted teaching programme was developed effective for staff nurses regarding the care of children on ventilators, Content validity of the tool was established by six experts. Data was analyzed by using descriptive statistics and inferential statistically in terms of frequency, percentage, mean, standard deviation, Chi-square values.

Results: - With regard to the pre-test knowledge assessment, the mean percentage of response was 66.97 %, with mean and SD of 17.62±2.43, which increased to 91.67% with mean and SD of 29.43±1.82 in the post-test. Further effectiveness of planned video assisted teaching programe was tested by inferential statistics using paired‘t’ test [(‘t’= 90.4970, P< 0.05)]. On the whole, the analysis revealed that the video assisted teaching programme was very effective in increasing the knowledge of staff nurses on care of children on ventilator.

Conclusion: Video assisted teaching programme was effective in increasing the knowledge of staff nurses regarding care of children on ventilator
