Tight bag is a clinical situation where excessive pressure needs to be applied to a reservoir bag of a breathing system to an intubated patient, which may or may not produce satisfactory ventilation. The various clinical scenarios and the appropriate steps for its prevention are described.

Background: It is currently presumed that spinal anaesthesia can compromise respiratory muscle function during carbon dioxide (CO2) pneumoperitoneum. This observational study was designed to delineate the respiratory effects of CO2 pneumoperitoneum under spinal anaesthesia.Patients & Methods: Forty one patients undergoing elective gynecological laparoscopy were administered spinal anaesthesia with 15 mg heavy bupivacaine and 50 mcg of fentanyl. Heart rare, blood pressure, tidal volume, respiratory rate and end tidal CO2 were serially recorded before, during and after the pneumoperitoneum. Arterial blood gas analysis was done before and 20 min after initiation of pneumoperitoneum.

Introduction
The objective of this study is to evaluate retention of CPR skills
among interns at 2 months after training and the need for
reeducation for better performance of skills.
Materials and Methods
The study involved 30 interns who underwent CPR training
using mannequin. None of the interns had prior proper CPR
training. During initial education classes, all 30 interns were
educated according to 2005 AHA guidelines for CPR until they
achieved 100% performance. Two months later, all interns
were tested for CPR skills. The parameters that were subjected
to assessment were: safe approach, call for help from
surroundings, opening of the airway, breathing check, pulse
check, adequacy of inspired volume in mouth to mouth
ventilation, adequacy of chest compressions 100/min
acceptable with proper hand positioning and compression
ventilation ratio (30:2), sequence and potentially injurious
performances.
Results
There was statistically significant deterioration in the
parameters like safe approach, response check, open the
airway, check breathing, adequate ventilation volume,
adequate chest compression and sequence at 2 months. Safe
approach, call for help, check breathing, CV ratio and sequence
were better performed by female interns. Other parameters
were better performed by male interns. Overall difference in
performance between males and females is not more.
Conclusions
In light of our findings, we conclude that as CPR skills have
deteriorated by 2 months itself, a short and inexpensive
retraining of skills is essential at two months after initial
education.
