Fig 1.0 â The structure of the peritoneum and the peritoneal cavity. Note how the visceral layer invaginates to cover the organs. The peritoneal cavity is a potential space between the parietal and visceral peritoneum.It contains only a thin film of peritoneal fluid, which consists of water, electrolytes, leukocytes and antibodies. The fluid serves two main functions: 1  It acts as a lubricant, enabling free movement of the abdominal viscera.he peritoneal cavity is not completely closed in females. The abdominal ostia of the uterine tubes opens into the peritoneal cavity providing a potential pathway between the female genital tract and the peritoneum.
0 Hi all. I know that the Apical Pulse or PMI or mitral valve or whatever you want to call it is located at the left 5th intercostal space, midclavicular line.
1. To determine the pulse deficit, take the radial and the apical pulses simultaneously. 2. Position the patient either in a supine or a sitting position and expose the patient's sternum and the left side of the chest.3. Using the appropriate anatomical landmarks, locate the radial and the apical pulses.ompare the two rates; the difference between the two is the pulse deficit, which reflects the number of ineffective cardiac contractions in 1 minute. If you find a pulse deficit, assess the patient for other signs and symptoms of decreased cardiac output, such as dyspnea, fatigue, chest pain, and palpitations. 1.
