LIFESAVING RELATED THEORIES AND MODELS

The Definition of Drowning

 

Drowning is the process of experiencing respiratory impairment from submersion/ immersion in liquid. Drowning outcomes should be classified as: death, morbidity, and no morbidity. This definition does not imply fatality, or even the necessity for medical treatment after removal of the cause, nor that any fluid necessarily enters the lungs. There was also consensus that the terms wet, dry, active, passive, silent, and secondary drowning should no longer be used.

The 4W Model of Drowning

 

According to the 4W Model of Drowning, when there is human activity in, on, around, near and under an aquatic environment, then, a drowning incident might happen to whomever (due to victim’s or rescuer’s mistake), wherever and under whatever circumstances. The factors that determine the outcome of drowning incidents are, in order of significance, rescuer characteristics (Who 1), casualty characteristics (Who 2), location (Wherever), and general circumstances (Whatever). Rescuer characteristics, and their interaction with other factors (mainly with casualty characteristics), appear to largely determine the outcome of drowning incidents. Risk taking behaviour leads to drowning when casualties are willing to seek pleasure by engaging themselves in aquatic activities with risk that perceive as controllable. The 4W model of drowning is a promising tool in lifesaving and lifeguarding.

The 5-Minutes Scanning Strategy

 

The 5 Minute Scanning Strategy teaches lifeguards a systematic approach to surveying their designated area. This method used physiological and psychological research to produce a simple yet effective system for lifeguards. This simple yet effective system requires lifeguards to change their posture and visual scanning pattern every 5 minutes. Lifeguards must count the people in their zone each time they change their posture or scanning strategy (every 5 minutes). Physiological and psychological research has shown that after 15 minutes of performing a simple task, a person's performance on that task gets worse. The Five Minute Scanning Strategy® was developed to help lifeguards stay alert while performing the task of watching people in the water.

The Connolly C-Zones

 

Lifesavers often discuss and analyze rescue and drowning incidents. The C-Zones Framework was designed to serve as an aid to such discussions. It is constituted by a number of zones (i.e., C1-concern, C2-crisis, C3-critical, C4-cardio-pulmonary resuscitation (CPR), C5-coma, C6-conclusion) and is simple enough to be easily remembered and quickly drawn on a piece of paper yet sufficiently detailed to be a serious analytical tool. The use of multicolored or different style lines permits the comparison of numerous casualty variations and outcomes on the one framework. The standard framework has a 20 min time limit describing the progress of an incident from its beginning to conclusion, but other versions of the framework are possible by adjusting the timing.

 

Before an event (to entering the framework) a person feels comfortable and non-threatened in, on, or near water and is in the Comfort Zone (C0). The Concern Zone (C1) describes the situation where an event changes the person’s feeling from being comfortable to being concerned (e.g., a fall into deep water). The Crisis Zone (C2) describes the situation when the person believes that his or her life is threatened. The Critical Zone (C3), describes the situation of a person who is close to exhaustion and who is losing the ability to self-help or to help a rescuer and may be about to panic or is already panicky, a point at which seconds count if the person is to survive. The CPR or Cardio- Pulmonary Resuscitation Zone (C4) depicts an unconscious, non breathing person with no heart beat in need of immediate life support. The Coma Zone (C5) portrays a person who has fallen into a coma. At the conclusion of an event, the Conclusion Zone C6, a casualty exits the framework in one of a number of possible physical states. Based on the International Life Saving drowning classification, the person is classified as either a fatal or nonfatal drowning. The working zones consist of C1 to C5. Each of the zones is divided into two subareas called minor and major to illustrate different degrees (or a deepening progression) within each zone. For example, in the Critical Zone (C3) minor, the person is close to unconsciousness but has not yet panicked; in Critical Zone (C3) major, the person is in a state of panic. This brief outline of the zones is expanded with examples later.

Overall, this framework can serve as a teaching aid and useful feedback tool offering a visual overview of rescue options and their potential or likely consequences at various stages in the drowning process. This information can be valuable to lifesavers, lifeguards, professional rescuers, lawyers, expert witnesses, and judges.

The Haddon Matrix

 

Drowning is a leading cause of death worldwide. Injury prevention models and theories aiming to educate people might play a role in drowning reduction. A framework for drowning prevention interventions based on the Haddon Matrix is proposed as means that can possibly assist professional rescuers in developing drowning prevention interventions. Given that the role of a lifeguard is mainly preventive and that successful prevention would reduce the need for rescue and treatment, the proposed framework could play a vital role in accident prevention and safety promotion (pre-event). Water safety educators can emphasize the in-event issues to prepare aquatic professionals and the general public to handle an emergency situation. Finally, post-event issues can help to generate feedback in all variables that are involved in a drowning episode.

Understanding Near-Death Experiences while Drowning

 

Research indicates that approximately one in five people who survive a close brush with death report a unique subjective state of consciousness known as a near-death experience (NDE). Such close brushes with death include drowning, and NDEs are often psychologically profound experiences with substantial and long-lasting implications for near-death experiencers’ (NDErs’) lives. Survivors of drowning-related NDEs might report their experiences to the lifesaving professionals who rescued them, and research indicates that how professionals respond to NDE disclosure can influence for good or ill the trajectory of NDErs’ processes of integrating the experiences into their subsequent lives. Two factors that seem to contribute to a helpful response to NDE disclosure are accurate knowledge about NDEs and knowledge of recommended interventions.

 

Following, we include a listing of recommendations into a form that hopefully makes them easy to recall in the demanding circumstances of a drowning resuscitation: one organized by the acronym “NDE.” The three components of the acronym are, first, the (D) don’ts—things for water safety professionals to avoid doing. Instead of the don’ts are the steps for professionals to (N) enact so that the resuscitant who is experiencing or experienced an NDE feels certain beneficial (E) effects.

 

Beginning with a search for a drowning victim and extending through the resuscitation process, a first don’t is to dismiss the possibility that the victim might be having an NDE. Rather, lifesaving professionals do best to assume that the victim may be having an NDE, which may include seeing the rescuers’ activities and hearing their conversations or even their thoughts. On this assumption, lifesaving professionals do best to narrate their activities and intentions—outloud if possible, but if circumstances do not allow, then silently. This narration can include introducing oneself by name; addressing the victim by name if the professional knows it; during a search, saying and thinking such messages as, “If you can see and/or hear me, I am looking for you” and during resuscitation, “If you can see and/or hear me, I am doing what I can to bring you back;” stating the date, time, and location; and explaining all activities related to the victim’s body, including but not limited to CPR procedures. If the victim remains physically unconscious following CPR, the professional does best to assume the victim may continue to be psychologically conscious and continues narrating outloud or silently that people in these circumstances sometimes find they continue to have conscious experience, including being able to see and hear people’s conversations and/or thoughts, and that if the victim is having this experience, it is normal. These activities on the part of the professional may help elucidate for the NDEr what he or she is experiencing.

Once a drowning survivor regains consciousness, an important don’t is to discourage the survivor from communicating about a possible NDE. Though some NDErs do not want to discuss their NDEs right away—if ever—most NDErs find it anywhere from helpful to urgently necessary to discuss their experiences. Consequently, lifesaving professionals do best to invite communication. If the survivor is on a ventilator or otherwise physically unable to speak, the professional does best to ask closed-ended questions that can be answered by yes or no—through means such as thumb up or down, head nod or shake, or one or two eye blinks. If the survivor can speak, the professional does best to ask primarily open-ended questions—those that cannot be answered by yes or no but rather that require a narrative response. The initial invitation can take a form such as, “During your drowning episode, did anything unusual happen?” or “People like you who’ve survived a drowning episode sometimes remember having been aware during a time they may have expected to be unconscious. Do you remember such an experience?” If the survivor indicates “no,” the professional does best to normalize that, “You are in the majority of people who remember nothing unusual during their critical events. However, on rare occasion, people who at first remember nothing, later remember something, and sometimes even people who remember something immediately don’t feel ready to discuss it right away. If, at any time in the future, you remember anything and want to discuss it, feel free to contact [me or another NDE-competent health professional] at [provide contact information].”

 

If the survivor indicates “yes,” then further invite, “Would you like to talk about it?” If a survivor indicates “no,” then the professional does best to say something like, “If you come to a point where you do want to discuss it, here is [my or another NDE-competent health professional’s] contact information.” If the survivor unable to speak indicates “yes,” the professional can invite further discussion with closed-ended questions, such as, “Such experiences have included one or more features. For example, did your experience include a sense of profound peace? A sense that your consciousness was functioning apart from your body? Seeing your body and/or the scene surrounding the crisis and/or your resuscitation? [continue with other NDE features described above, ending with a sense of returning to the physical body]. Did you have other features in your experience? [If so, and the survivor can write, provide them with the opportunity to describe the feature(s) in writing.] Were any aspects of your experience distressing to you?”. If a survivor able to speak indicates “yes,” a professional can invite further discussion open-endedly, such as “I’m interested in hearing as much as you’d like to tell me” and respond to the disclosure by reflecting back to the survivor, through paraphrasing and summarizing, the main points the survivor is expressing.

 

 If a survivor indicates even one of the NDE features described above, the professional does best not to deny that the experience was an NDE—a phenomenon that has been professionally recognized and labeled. Rather, the professional does best to know and name the experience as an NDE and to use research-based NDE information to answer questions the survivor might ask.

 

Because most NDErs perceive their NDEs to have been absolutely real, if not hyper-real, a third don’t for lifesaving professionals is to disbelieve that the NDE could be a real experience. Rather, they do best to naturalize NDErs’ feelings of reality to help NDErs feel endorsed in their perception that their experience was real or, at least, potentially real.

Because NDEs involve an often profound experience of an alternate reality, NDErs sometimes fear that they or the experience was crazy—or fear that others will think so. Lifesaving professionals do best not to diagnose NDEs or NDErs as somehow related to mental illness. Rather, they do best to normalize the experience as common—reported by about one in five people who survive a close brush with death—and shown by research not to be, in and of themselves, indicators of mental illness but rather to be reported by people of all ages and characteristics. This information can help an NDEr feel equalized rather than pathologized on the basis of the NDE alone.

 

Similarly, some professionals in whom NDErs have confided have demonized NDEs—considered them somehow evil, malevolent, or “of the devil.” Rather, lifesaving professionals do best to numinize the experience, that is, convey the spiritual neutrality or, potentially, the spiritual benefits of NDEs. In this way, the NDEr will feel enlightened that he or she has the potential to find the experience spiritually growthful.

 

Another temptation that lifesaving professionals may experience is an urge to determine for an NDEr the meaning of the NDE. Rather, professionals do best to inquire what meaning an NDEr attributes to his or her experience by asking questions like, “What do you make of your experience?” and “What does your experience mean to you?” (Roberta Moore Video Productions, 2013). Questions like these enable NDErs to ponder their NDEs and consider for themselves what the experiences mean to them—a meaning that may very well evolve as the NDEr reflects on the experience over time.

Finally, in general, the deeper an NDE—the more and more intense the features of the experience—the greater will be the challenge for the NDEr to integrate the experience into subsequent life. Participants at an NDErs’ retreat indicated an average of 13 years to adjust completely to their NDEs. Thus, lifesaving professionals do best not to deprive NDErs of resources for further information and support but, rather, to navigate NDErs—and their families—toward such resources. One fundamental resource is contact information of health professionals competent to further discuss the NDE if the experiencer wishes to do so—whether that is the lifesaving professional or another qualified professional.

Online resources include International Association for Near-Death Studies (www.iands.org), the Near-Death Experience Research Foundation (www.nderf.org), and the American Center for the Integration of Spiritually Transformative Experiences (www.aciste.org).

The Instinctive Drowning Response

 

Beginning in 1959, a 21-year observational study at Orchard Beach, Bronx, NY was carried out. This method conformed to the qualitative research methods. It was not ethical to use a treatment and control experimental design at Orchard Beach.  The research question was “Is there a difference between a drowning person and a swimmer in distress?” Filming the struggle and rescues of drowning people upheld the research hypothesis. The qualitative study documented there was a difference between a drowning person and swimmers in distress. Pia developed the prevailing water crises classification. The drowning vs. distress defined feature categorical classification was first shown in On Drowning. Categorical classifications were discussed comprehensively in Reflections on Lifeguard Surveillance Programs.

The Instinctive Drowning Response represents a person's attempts to avoid the actual or perceived suffocation in the water. The suffocation in water triggers a constellation of autonomic nervous system responses that result in external, unlearned, instinctive drowning movements that are easily recognizable by trained lifeguards. Here are the characteristics of the Instinctive Drowning Response.

 

  1. Except in rare circumstances, drowning people are physiologically unable to call out for help. The respiratory system was designed for breathing. Speech is the secondary or overlaid function. Breathing must be fulfilled, before speech occurs.
  2. Drowning people’s mouths alternately sink below and reappear above the surface of the water. The mouths of drowning people are not above the surface of the water long enough for them to exhale, inhale, and call out for help. When the drowning people’s mouths are above the surface, they exhale and inhale quickly as their mouths start to sink below the surface of the water.
  3. Drowning people cannot wave for help. Nature instinctively forces them to extend their arms laterally and press down on the water’s surface. Pressing down on the surface of the water, permits drowning people to leverage their bodies so they can lift their mouths out of the water to breathe.
  4. Throughout the Instinctive Drowning Response, drowning people cannot voluntarily control their arm movements. Physiologically, drowning people who are struggling on the surface of the water cannot stop drowning and perform voluntary movements such as waving for help, moving toward a rescuer, or reaching out for a piece of rescue equipment.
  5. From beginning to end of the Instinctive Drowning Response people’s bodies remain upright in the water, with no evidence of a supporting kick. Unless rescued by a trained lifeguard, these drowning people can only struggle on the surface of the water from 20 to 60 seconds before submersion occurs.

Observations at Orchard Beach over a 21-year period revealed that drowning people were often surrounded by patrons who did not realize that a drowning was occurring next to them. It is vital that new lifeguards be trained to rely on their assessment of the signs of drowning.  They must be instructed to begin saving the drowning person based on their scanning assessment. Unseasoned lifeguards cannot wait for patrons or more experienced to tell them that a person is drowning.

The RID Factor of Drowning

 

Most swimming-related deaths are unwitnessed drownings in which neither the lifeguard nor nearby swimmers noticed the drowning person struggle and slip below the surface of the water. A research study examined published accounts of drownings in the United States from 1910 to 1980. This assessment pointed out when active drownings occur the lifeguard failed to Recognize the instinctive drowning response, secondary duties Intruded on the lifeguard’s primary responsibility, patron surveillance, occurred, or there was Distraction from surveillance duties.  Understanding the RID Factor can be used to keep the patron surveillance system operating properly.

Recognition.

 

A vast majority of a lifeguard’s time is spent in preventing people from either engaging in dangerous practices or placing themselves in perilous conditions. When the preventive work of a lifeguard is effective, potential life-threatening conditions are corrected before rescues or injuries. Drowning and distress are the two types of water crises. Distress involves a swimmer who is unable to return to safety without help. The United States Lifesaving Association built on the original 1970 water crisis classification and added thirteen distressed swimmer descriptions to their training manual. Drownings can be subdivided into two groups; the instinctive drowning response and passive drowning people. Because of a sudden loss of consciousness, the passive drowning person slips under water without waving or calling out for help or struggling on or beneath the surface of the water. This emergency is caused by a heart attack, stroke, hyperventilation, a blow to the head, cold water immersion, or excessive alcohol consumption.

Intrusion.

 

Miller & Rice discuss open systems organizational theory. In this model, organizations are open systems that import, convert, and then export services or products. Parks and recreation departments take in individuals provide leisure activities, and individuals return home. Unfortunately, these organizations have limited finances and are often overworked and understaffed. A lifeguard performing surveillance work might appear available for more duties. Since emergencies can occur when few bathers are present, lifeguards should never be assigned recreational or maintenance duties during patron surveillance. Lifeguards cannot clean aquatic facilities, rent beach umbrellas or chairs, taking admission tickets, or giving swimming lessons when they are or should be part of the surveillance system. Asking lifeguards simultaneously to coach swimmers, perform maintenance duties, and watch bathers increases the likelihood of a drowning or injury occurring.

Distraction.

 

Distraction occurs when lifeguards engage in social conversations or daydream. Young children can sometimes struggle for only 20 seconds before submerging. I think, any lifeguard who takes his or her attention away from patron surveillance for more 10 seconds is inattentive to bathers. This strict standard of care can be met if lifeguards receive regularly scheduled breaks from their surveillance duties. In the United States, the American Red Cross’ lifeguard manual notes “You should take a break at least once an hour.” The USLA encourages providing continuous surveillance duty lifeguards with a 15-minute every hour.
