Two cases of pneumoperitoneum following tension pneumothorax are described. Lungs in both patients had identifiable pathology and were ventilated with high inflation pressure and moderate positive end-expired pressure (PEEP). Laparotomy was performed in both patients with no evidence of intra-abdominal viscus perforations. A possible mechanism for the(More)
The aim of this study is to observe the effects of dark chocolate on endothelial function after a series of successive apnea dives in non-thermoneutral water. Twenty breath-hold divers were divided into two groups: a control group (8 males and 2 females) and a chocolate group (9 males and 1 female). The control group was asked to perform a series of dives(More)
OBJECTIVE The aim of the study was to observe the effects of dark chocolate on endothelial function after scuba diving. METHODS Forty-two male scuba divers were divided into two groups: a control (n=21) and a chocolate group (n=21). They performed a 33-metres deep scuba-air dive for 20 minutes in a diving pool (Nemo 33, Brussels). Water temperature was(More)
The dynamic responses of 3 transducer-tubing systems (TTS) were documented using square and sine wave generators. The TTS tested were P23 ID with 5 feet tubing (P23-5'), P23 ID with 6 inches tubing (P23-6") and P50A transducer with no tubing (P50). Natural frequencies were 45, 33, and 7 Hz for P50, P23-6", and P23-5', respectively. All were underdamped(More)
