Protective Gowns are made of materials that provide an effective barrier, are worn during invasive procedures that result in the splashing of blood or other body fluids. Protective gowns are worn in the isolation room when working directly with the patient.

Psychotherapy is a general term for a way of treating mental & emotional disorders by talking about the condition and related issues with a mental health professional. The common types of psychotherapy include art therapy, behavior therapy, cognitive therapy and dialectical behavior therapy.

Pulse Oximetry is a simple non-invasive method of monitoring the percentage of haemoglobin, which is saturated with oxygen. The pulse oximeter consists of a probe attached to the patients finger or ear lobe, which is linked to a computerised unit. The unit displays the percentage of Hb saturated with oxygen together with an audible signal for each pulse beat and a calculated heart rate. An oximeter detects hypoxia before the patient becomes clinically cyanosed.

The portable defibrillator operates on rechargeable batteries and therefore make use of DC-DC converters for stepping up the voltage required for charging the storage capacitor. The maximum energy delivered by portable defibrillator is generally 300 ohm delivered into 50 ohm load which is equivalent to about 400 Ws of stored energy. Since the patient impedance can vary considerably, it has a strong effect on defibrillation effectiveness.

PA catheters are long catheters, which are introduced through large bore central venous lines usually in the subclavian or internal jugular veins. The catheters have a balloon at their tip, which allows them to be carried via the flow of blood or floated to their resting position within the PA. The catheter has a distal lumen, which allows for measuring PA pressures and obtaining mixed venous blood samples. A proximal lumen permits fluid infusions and manometric measurement in the right atrium. It measures cardiac output via a technique known as thermodilution. A small bolus of cold 5% dextrose is quickly injected into the right atrium via the proximal lumen of the PA catheter.

Pulse meter is used to measure the blood flow rate in the finger or earlobe by shining light into the skin and sensing changes in light density in the photoelectric sensor; the pulsemeter then calculates and display the rate in bpm.

Pigtail diagnostic catheter is used to cannulate the contra lateral common iliac artery over the aortic bifurcation. It is placed at the apex of the left kidney for ideal imaging. Because the right kidney is usually lower than the left kidney, placement of the pigtail catheter at the top of the left kidney facilitates the visualization of bilateral kidneys and their respective blood supplies.

A portable fluoroscope utilizes a hingedly mounted, light shielded, fluorescent screen positioned in front of a look-through radiation shield. A leaded glass eyepiece positioned within the radiation shield is used as a radiation resistant viewing port to observe the image produced on the fluorescent screen by an irradiated object. The use of a relatively small piece of lead glass in the viewing port of the present device in comparison to the use of a lead-glass plate the size of the fluorescent screen, which is immediately adjacent thereto in the prior art, has resulted in a substantial reduction in weight and cost for the same degree of radiation protection.

Pulse oximetry is a non-invasive method of measuring hemoglobin saturation. Being non-invasive, it does not require a blood sample to obtain a result. It uses spectrophotometry to measure hemoglobin saturation. It uses two wave lengths of light, one red and one infrared. Pulse oximeters use two light emitting diodes to transmit light through a capillary bed to a silicone photodiode detector.

Patent Ductus Arteriosus (PDA) is a heart problem that occurs soon after birth in some babies. A PDA is a type of congenital heart defect. The symptom includes shortness of breath & cardiac arrhythmia and progress to congestive heart failure if left uncorrected. A patent ductus arteriosus allows oxygenated blood to flow down its pressure gradient from the aorta to the pulmonary arteries. Patent ductus arteriosus is the persistence of a normal fetal structure between the left pulmonary artery and the descending aorta. It is an abnormal opening between two major blood vessels, the aorta and the pulmonary artery.

Patent Foramen Ovale Closure Device includes a closure device, which is releasably connectable to an actuator. The device includes a proximal segment, an intermediate segment and a distal segment.

PaceMaster Treadmills offer the complete fitness and exercise solution. PaceMaster treadmills allow users to accurately quantify their exercise regimen's fitness benefits and build a program that acts as an 'on-call' personal trainer. This help exercisers personally count their way to cardio fitness.

Peripherally Inserted Central Catheter (PICC) is a form of intravenous access that is used for a prolonged period of time. A PICC is inserted in a peripheral vein, such as the cephalic vein, basilic vein or brachial vein and then advanced through increasingly larger veins, toward the heart until the tip rests in the distal superior vena cava or cavo-atrial junction. PICCs are inserted by radiologists, physician assistants, radiologist assistants or certified registered nurses using ultrasound, chest radiographs and fluoroscopy to aid in the insertion and to confirm placement.

Perfusion catheter is indicated for balloon dilatation of the stenotic portion of a coronary artery or bypass graft stenosis for the purpose of improving myocardial perfusion. These are also designed to provide distal blood perfusion during balloon inflations

Pigtail catheter is an angiographic catheter with a tightly curled end to reduce the impact of the injectant on the vessel wall or to remain in a chamber or space for drainage.
